Experimental Investigation of the Effects of Gasoline-Methyl Ethyl Ketone Fuel Blends on Engine Performance and Exhaust Emissions

Gasoline engines have been widely used because of operating with stoichiometric ratio and lower exhaust emissions compared to compression ignition engines. However, thermal efficiency is less than diesel engines due to lower compression ratio. In the present study, the influences of methyl ethyl addition were researched on engine performance, CO, CO2 and HC emissions in a single cylinder spark ignition engine. For this purpose, the test engine was run at wide-open throttle, engine speeds of 2400, 2800, 3200, 3600, 4000 rpm and the variations of engine torque, effective power, specific fuel consumption (SFC), thermal efficiency, CO, CO2 and HC emissions were investigated. It has been observed that engine power and torque increase and SFC decreases as methyl ethyl ketone is added to gasoline. It was observed that the thermal efficiency at 2800 rpm increased by 6.47%, 13.81% and 19.51%, respectively, with MEK20, MEK30 and MEK40 test fuels compared to gasoline. As the methyl ethyl ketone ratio in the blended fuels increased, HC and CO emissions reduced compared to gasoline. As a result, it was seen that methyl ethyl ketone additive can be utilized easily in a spark ignition engine without making any modification.

A CFD ignition model to predict average-cycle combustion in SI engines with extreme EGR levels

Control of the combustion process in Spark-Ignition (SI) engines operated with extreme dilution from exhaust gas re-circulation (EGR) represents one of the major limitations in the industrial design of such technology. Numerical approaches able to describe in detail the formation of the early flame kernel become essential to face such an ambitious task. This work presents a RANS-based multi-dimensional model of the combustion process, including an advanced description of the ignition stage to consider its stochastic re-ignitions within the average cycle prediction. The spark-channel is described as a column of Lagrangian parcels that represent early flame kernels, whose growth is controlled by the laminar flame speed and energy input from the electrical circuit. The spatial evolution of each parcel is computed according to a scaled value of the average-flow speed, to mimic the smooth but short elongation of the mean-cycle channel produced by stochastic restrikes affecting the single-cycle arcs. To clarify this phenomenon and assess the proposed CFD method, a series of experiments are performed in a single cylinder SI engine with optical access, running at a low-load cruise-speed operating condition. Increasing EGR levels are tested up to the onset of misfire, with measurements of the secondary-circuit features and of the flame evolution through high-speed imaging. Satisfactory results are achieved in terms of numerical-experimental comparison of the cycle-averaged in-cylinder pressure, discharge parameters, and spatial flame distribution, demonstrating the reliability of the proposed numerical approach.

The Effect of Dual Fuel Producer Gases with Y-Shaped Mixing Chamber on Single Cylinder Spark Ignition Engine Operation

In the operation of SI engines, alternative biomass fuels such as rice husk can be utilized. This will contribute limit the consumption of fossil fuels. The dual-fuel approach can also be employed on SI engines. One of the solutions that can be employed in dual-fuel SI engines with gasoline is producer gas, a flammable gas created by biomass gasification. However, the numerous methods of incorporating gases into SI engines necessitate substantial investigation. In this study, producer gas and gasoline are combined and fed into an SI engine. The dual fuel is used to power the single-cylinder SI engine. The most optimal operation of the Y-shaped mixing chamber is investigated. Experiments were conducted to determine the optimal air-producer gas ratio values based on the SI engine's ability to operate in time at idle. Two variables were chosen as inputs: air producer gas ratio and fuel mixture percentage. According to the study's findings, an air-producer-gas ratio of 1.5:1 with 50% gasoline results in better mixing. The single-cylinder SI engine has been running smoothly and longer than other parameters without knocking.

Derivation and validation of heat transfer model for Spark-Ignition engine cylinder head

The valve train is located in the engine cylinder head, which has various operational heat transfer mechanisms to accommodate the combustion process. Most heat transfer studies in this area have only addressed medium-to high-power vehicles at a single running speed. In this study, a model of an air-cooled underbone motorcycle valve, valve seat, and engine cylinder head was tested to determine the thermal characteristics using actual engine operating conditions at low, medium, and high engine speeds. One-dimensional thermal simulation analyses were conducted to obtain the instantaneous heat-transfer coefficients of an actual engine. The average thermal value was determined as the boundary condition in the three-dimensional thermal analysis. A three-dimensional model was prepared using the ANSYS commercial computational fluid dynamics software package. The results show that as the engine speed increases, so does the thermal load toward the component in the engine cylinder head. The strongest temperature regions were concentrated around the combustion face. The exhaust valve held most of the heat, with the valve neck recording the highest temperature. For the intake valve, the combustion face registered the majority of the heat. The heat flux intensity was gathered in the contact surface area between the valve and its seat, between the valve stem and guide, and between the stem guide and tip section. A thermal survey was used to validate the three modelling results for two separate engine datasets. The cumulative relative errors for intake and exhaust valve seats for low engine speeds were 3.73% and 0.17%, respectively. The intake and exhaust valve seats had cumulative relative errors of 4.12% and 0.70%, respectively, at intermediate speeds. This methodology provides valuable information for analysing the heat characterisation of air-cooled engines. It can also be a useful blueprint for the automotive industry and other researchers involved in thermal measurements.

Experimental Investigation on Multi Cylinder Spark Ignition Engine Fuelled With Waste Plastic Oil with Oxygenated Fuels

Abstract: In the current day situation, emissions associated with the exhaust of automobiles resulting in global warming are a major threat to the entire world and also harmful to health. In this perspective, waste plastic solid is presently getting renewed interest. Plastics have now become indispensable materials in the modern world and application in the industrial field is continuously increasing. As substitute, non-biodegradable, and renewable fuel, waste plastic oil is getting rising attention. An experimental investigation is conducted to evaluate the emission and performance characteristics of a multi-cylinder spark ignition engine fuelled with Plastic Petrol derived from waste plastic by the process of pyrolysis. Petrol is blended with waste plastic pyrolysis oil as 10%WPPO and 85% petrol as blend-I and 20%WPPO and 75% petrol as blend-II. The performance and emission characteristics are found for both the blends and compared with the characteristics of petrol. Some amounts of oxygenated fuels viz., ethanol and methanol are added in the concentration of 5% each to the both the blends and their characteristics are compared to the blends without oxygenate fuels and sole petrol. The tests are conducted using each of the Gasoline and Plastic Petrol with oxygenated fuel additives with the engine working at variable load of 0 to 7 kg for constant speed at 1500 rpm. The differences in the measured performance from the baseline operation of the engine with petrol, blends with addition of oxygenated fuels and without addition of oxygenated fuels are compared. It resulted that, by adding additives the brake thermal efficiency of the engine improved. The CO and HC emissions are reduced but NOX and CO2 emissions are increased for all the blends when compared to petrol.

Intake Manifold Flow Study using Numerical Method with all Runners Opened

Intake manifolds have to be designed to improve engine performance by avoiding the phenomena like inter-cylinder robbery of charge, inertia of the flow in the individual branch pipes, resonance of the air masses in the pipes and the Helmholtz effect. The objective of work is to predict and analyze the flow through intake manifold of four cylinder spark ignition engine. One of the important factors is air flow inside the intake manifold; the ideal intake manifold distributes flow evenly to the piston valves. The structural analysis has been conducted to decide the thickness and material that is suitable for intake manifold to withstand bursting pressure. Three-dimensional inlet manifold was modeled in ANSYS workbench and numerically analyzed by using the commercially available FLUENT software to study the pressure, velocity and flow characteristics inside the runner. The steady state analysis has been carried out for three for All runners open, The predicted results of total pressure loss and total outlet mass flow were discussed. Inlet pipe and plenum connection creates a back step geometry which causes more total pressure loss due to flow recirculation in conventional model. Tapering the geometry is causing more inlet mass flow due to reduction in total pressure loss in the plenum chamber.

The Effect of Pine Oil Emulsifier on Gasoline-Alcohol Blends in a Spark Ignition Engine with Multi-Point Fuel Injection

This paper presents the results of a study conducted to establish the effect of pine oil as an emulsifier on gasoline-alcohol blends in a twin cylinder spark ignition (SI) engine with multi-point fuel injection (MPFI) system. The test fuels were prepared by blending both ethanol and isopropanol with gasoline separately and pine oil was used as an emulsifier to either of the fuel blends. The 3 sets of fuel samples were used in which the concentration of pine oil was kept constant at 20 % by volume, while the concentration of both alcohols namely ethanol and isopropanol was varied from 5 to 15 % and the rest is gasoline. The experiments were conducted at different loads from 0 to 100 % in steps of 20 % at a constant speed of 2500 rpm. The results demonstrate that the use of gasoline-alcohol blends with pine oil in MPFI SI engine improved brake thermal efficiency (BTE) by 7.8 and 11.2 % with the higher proportions of ethanol and isopropanol in gasoline, i.e., E15 and IPA15, respectively when compared to neat gasoline. Carbon monoxide (CO) and hydrocarbon (HC) emissions reduce by 22.5 and 27.5 %, respectively while HC emissions reduce by 21.5 and 28.8 %, respectively with the E15 and IPA15, respectively. However, higher amounts of nitrogen oxides (NOx) emissions is the negative impact of the said blends. It was also observed that there is a reduction in brake specific fuel consumption (BSFC).

Improvement of SI engine combustion with ammonia as fuel: Effect of ammonia dissociation prior to combustion

Although recent studies have shown the possibility of running ‘standard’ spark-ignition engines with pure ammonia, the operating range remains limited mainly due to the unfavorable characteristics of ammonia for premixed combustion and often requires the addition of a complementary fuel such as H2 to extend it. As the best way to add H2 is to crack ammonia directly on-board, this paper focuses on the impact of the upstream cracking level of ammonia on the performance and emissions of a single cylinder spark ignition engine. Experiments were performed over several equivalence ratios, dissociation rates and load conditions. It is confirmed that only a slight rate of ammonia dissociation (10%) upstream of the combustion considerably enhances the engine's operating range thanks to a better combustion stability. In terms of pollutant emissions, the partial dissociation of ammonia, especially for slightly lean mixtures induces a very clear trade-off between high NOx and high unburned ammonia level for high and low ammonia dissociation rates, respectively. Therefore, cracking NH3 does not only improve the operating range of ammonia-fueled spark ignition engines but can also help to reduce NH3. However, to reach the same engine output work, higher ammonia fuel consumption will be necessary since the global system efficiency is lower using fuel dissociation. In addition, the global warming effect is increased with dissociation level since a higher level of N2O is generated by the hydrogen contribution.

Enhancement and Analytical Assessment of Single Cylinder Spark Ignition Engine Operated on Liquefied Petroleum Gas (LPG)

Utilizing gaseous fuels, such as Liquefied Petroleum Gas (LPG) and Liquefied Natural Gas (LNG), has become widespread in the realm of commercial vehicles. This undertaking is driven by the primary goal of adapting an existing gasoline-fuelled Spark Ignition (SI) engine to seamlessly operate with LPG. Simultaneously, the secondary aim of this Endeavor involves a meticulous examination of the theoretical performance of the engine when fuelled with both LPG and gasoline. A comprehensive analytical comparison has been conducted to scrutinize the engine's performance under these diverse fuel scenarios. The engine under consideration for this scholarly pursuit is a four-stroke single cylinder 7 kW TVS King Bajaj engine. To achieve the desired modification, a meticulously chosen first-generation LPG conversion kit has been identified and seamlessly integrated into the existing gasoline-fuelled engine. This conversion kit comprises essential components such as a mixing unit, pressure regulator, vacuum lock-off and filter, selector switch, solenoid valve, multi-functional valve, and LPG cylinder. After the successful adaptation of the engine to run on both fuels, it was mounted on a water dynamometer to systematically assess its performance and emission characteristics. The outcomes of the analytical engine performance evaluation are remarkable. The brake power output exhibited an impressive 7.2% improvement, coupled with a noteworthy 1.98% reduction in brake specific fuel consumption when the engine operated on LPG instead of gasoline. Moreover, when running on LPG, the engine's brake thermal efficiency experienced a commendable boost of 2.66%. These discerning parametric analyses underscore LPG as an up-and-coming alternative to gasoline, not only in terms of performance but also in consideration of anti knock properties, emission characteristics, and the cost-effectiveness of the fuel.

One-dimensional numerical simulations of single-cylinder spark ignition engine fuelled H2O based emulsion fuel, methanol blends, and gasoline conventional

In this work, we have used two types of renewable fuels for testing in one-dimensional simulation software and comparing its performance and emission characteristics with 100% Gasoline fuel. For this work, we have used ethanol 20%-H2O 2%, and gasoline 90% based micro-emulsion fuel and blends of 20% Methanol in 80% Gasoline fuel as an Alternative fuel. This work is done computationally on one-dimensional licensed AVL Boost Simulation Software. The micro-emulsion fuel was prepared in the lab by adding ethanol as co-surfactant and H2O as an additive in the blended fuel. The other alternative fuel Methanol blended 20% with Gasoline 80% is also used to test the performance and emission characteristics of multi-cylinder Spark Ignition Engine. This is a novel based work done to improve the performance and Emissions of 3- Cylinder Spark Ignition Engine. The performance parameters like power, Torque, BSFC, BMEP, showed better results & emissions like CO, HC, & NOx showed significant decrease as compared to conventional 100% Gasoline fuel. Micro-emulsion fuel were better in emissions particularly NOx, which showed 25% decreases than Methanol fuel. Also showed slightly better power & Torque output by 10% than Methanol blend. Both the renewable fuel were compared with gasoline 100%.

Experimental investigation of alcohol blending effect on the performances of a single cylinder spark-ignition marine engine

This work represents an experimental study on the performances of a single cylinder spark-ignition marine engine fueled by ethanol blends. Several studies have been carried out to investigate the use of alternative fuels in spark-ignition engines to improve their efficiency and reduce exhaust emissions. The experiments have been conducted on a test bed under full load condition with varied engine speed from 1000 rpm to 3000 rpm and an engine wall’s temperature fixed between 75°C – 85°C. The study includes the blending of ethanol and gasoline with different blending ratios (E0, E5, E15, and E20). The results of the study showed that E15 conducted for better results in specific fuel consumption without notable loss in engine performances in comparison with other blends. Experiments showed that ethanol blends are a viable option as a fuel alternative in spark-ignition engines due to its potential to conserve acceptable engine performances.

Merit function for simultaneous optimization of fuel properties, naturally aspirated spark-ignition engines equipped with port fuel injection system, and regulated emissions

Merit function allows systematically rank gasolines to better understand the relationship between fuel properties and thermal engine efficiency relative to E10 gasoline. In this sense, merit function was employed to ranking Mexican gasolines and for optimization of fuel properties. The performance of fuels was extended to investigate thermal engine efficiency, fuel consumption, and regulated emissions. Three base gasolines were blended with ethyl-tert-butyl-ether (ETBE), methanol, ethanol, dimethyl carbonate or isobutanol at 3.5, 10, and 20 wt% of oxygen. Fuels were tested in a mono cylinder spark-ignition research engine, which is coupled to an asynchronous dynamometer and equipped with an emissions analysis system.Results obtained in the mono cylinder engine show that gasolines blended with ETBE, or ethanol improve thermal engine efficiency (+2.4%) in line with a reduction of fuel consumption (−1.0%) relative to Premium gasoline. Besides, emissions of NO (−3.6%), HC (−3.1%), and CO (−8.5%) show a steadily reduction compared to those observed for Premium gasoline. However, gasolines blended with ethanol present a major impact on thermal engine efficiency, fuel consumption, and emissions (of CO and hydrocarbons) respect to those blended with ETBE. In fact, we found that a gasoline blended with ethanol (9.4% vol.%) could help to reduce by 5.5%, 7.5%, 11.3%, and 1.2% emissions of NO, HC, CO, and CO2, respectively, by boosting thermal engine efficiency (+3.5%) with a reduction on fuel consumption (−1.0%), relative to Premium gasoline. For the old vehicular fleet from México, a merit function based on Regular gasoline is proposed. It was found that the US E10 gasoline has a negative impact on thermal engine efficiency (−1.0%) relative to Regular gasoline. Results obtained in this investigation confirm that boosting the merit score by enhancing fuel properties relative to E10 or Regular gasolines, result in a reduction of the final emissions. However, there is not a clear correlation among the magnitude of variation of emissions, fuel consumption, thermal engine efficiency, and merit score.

Performance Evaluation of a Single Cylinder Spark Ignition Engine Fuelled by Mixing Ethanol and Gasoline

The use of ethanol blend as an alternative source of fuel for developing clean and sustainable energy sources has grown considerably. In this study, the performance characteristics of an air-cooled, single-cylinder 4-stroke Spark Ignition (SI) engine (TD201) with a compression ratio of 8.5:1 was determined using gasoline and different blend ratios of ethanol and gasoline (E0, E2, E4, E6, E8, E10, and E12) at a varied engine speed of 2000rpm, 2200rpm, 2400rpm, 2600rpm and 2800rpm. The results revealed that as the ethanol content of the blend increases, the heating value decreases while octane value increases. The experimental results indicated that the brake torque, and power increase as the ethanol content in the blends increases. However, BSFC and exhaust temperature decreases as the ethanol content in the blends increases because of the oxygen enrichment. The emissions of unburned hydrocarbon and carbon monoxide reduce while carbon dioxide and ethanol content increases when compared with the reference fuel (E0).

Theoretical and Experimental Studies on The Combustion of Synthetic Fuels in Spark Ignition Engines.(Dept.M)

A theoretical and experimental investigation on the performance and emission of spark ignition engine have been made using gasoline, alcohol and gasoline-alcohol mixture as fuels. A thermodynamic model has been developed with superimposed pseudo-kinetic NO and CO formation. This has been used to compute estimated performance and emission data for a spark ignition engine. The model has also been used to compare the prediction performance and emission data when operating the engine with methanol, ethanol and gasoline fuels. A series of an experimental tests were carried out on a single cylinder spark ignition engine to confirm the theoretical results of the mathematical model. Comparison of results indicates that alcohol seems to be a viable alternative fuel to gasoline with respect to efficient, operational and emission considerations.

Parametric Investigation on Single Cylinder Spark Ignition Engine Fueled Methanol Blends; Water-Based Micro Emulsions and Conventional Gasoline

In this contribution, the investigation conducted on alternative fuels includes methanol 20% blended with gasoline 80% and emulsion-based fuel with the composition of gasoline 80%, ethanol 15%, and H2O 5% are compared with 100% conventional gasoline fuel. These fueled single-cylinders spark ignition engine is studied for checking their performance and emission characteristics as per future emission norms. This work is performed on One-dimensional AVL Boost Simulation Software. The simulations predicted the performance and emission characteristics were far lesser than conventional 100% gasoline. These fuels meet the strict emission regulations of Euro VII. The main purpose of this investigation is to use alternative fuels to improve the performance and emission characteristics of the single- cylinder spark ignition engine and reduce the consumption of fossil fuel reserves. This investigation led to the conclusion that by using methanol 20% in 80% gasoline and micro-emulsion, fuel improves the power, BSFC (brake specific fuel consumption), thermal efficiency and combustion properties of the single-cylinder spark-ignition engine. The CO, HC and NOx emissions were also reduced for alternative fuel than 100% gasoline fuel. The novel water-based emulsion fuel showed the lowest value of NOx emissions as compared to blended 20% methanol with 80% gasoline and 100% gasoline fuel.

The Effect of Injection Parameters on Fuel Consumption and Emissions in A PFI Small Spark Ignition Engine

Mixture formation in port fuel spark ignition engines is one of the most im-portant parameters, which affect combustion and emissions. In this study, the ef-fects of different injection start timings and some other port fuel injection (PFI) parameters on the performance and emissions of a water cooled and single cylin-der spark ignition engine were examined experimentally. The experiments were performed at different engine speeds (1200 and 1500 rpm for effect of injection pressure and 1500 rpm for changing injection timings) and different engine loads (3 bar and 5 bar for injection pressure and 1 bar and 5 bar for start of injection). The start of injection was chosen according to intake pressure measurements. The experiment results showed that brake specific fuel consumption (BSFC) and total hydrocarbon (THC) emissions are increased by the increase of the injection pressure. Because with the increase of injection pressure, the fuel can reach the intake manifold wall or intake valve. Therefore, the fuel enters the cylinder as a droplet. Different start of injection experiments showed that injection times have an effect on emissions and performance. The minimum brake specific fuel con-sumption and THC values were obtained at -243 °CA value of injection start. The twice injection in one cycle increased brake specific fuel consumption and THC emissions.

Design and Analysis of Exhaust System for Ultra-fuel Efficient Vehicles

Exhaust systems for Internal Combustion (I.C) engines have been finding their significance in the performance of an engine from its inception. One of the detrimental factors for the performance of exhaust is the amount of backpressure building through the flow. This study focuses on reducing backpressure occurring in the exhaust and increasing the ease of manufacturability for a 50 cm3 single cylinder Spark Ignition (S.I.) engine used in an ultra-fuel efficient vehicle. The flow of the exhaust gases from the engine are analyzed with the help of ram induction theory. Computational Fluid Dynamics has been employed to facilitate the study of turbulent flow in the exhaust and obtain results close to a streamlined flow. Parameters such as dimensions, operating pressures and velocities are calculated to understand the flow characteristics. The results strengthen the bilateral scopes of study here being, smooth flow of exhaust gases and greater manufacturability. The bend and end cone angles are defined in such a way that the wastage of material is least and complexity of the geometry is moderate. The exhaust has been designed keeping the chassis and engine complacency constraints in concern. The results of this study can be useful in manufacturing and integration with light gasoline engines, but of the same orientation as the one discussed here, for prototyping purposes.

Computational parametric investigation on single cylinder constant speed spark ignition engine fuelled water-based micro-emulsion, ethanol blends, and conventional gasoline

In this contribution two Alternative fuels in fixed proportions were compared with conventional 100% gasoline fuel on a constant Speed single cylinder based generator. This work defines the complete state of the art work done on computational Simulation Software on AVL Boost. In this work, we have compared the performance and emission characteristics of single cylinder spark Ignition engine constant speed of 3000 rpm fuelled conventional Gasoline 100% with blended Alternative fuel Ethanol15% with 85% Gasoline, and water-Ethanol based micro-emulsion fuel Gasoline 85% Ethanol 10% and H2O 5% on licence based Simulation Software AVL Boost. The performance parameters were checked for all the three types of fuels and emission characteristics were compared with all the three types of fuels. The results were very promising for water-Ethanol based micro-emulsion fuel as far as the emission characteristics are concerned. Ethanol 15% blends with 85% Gasoline also showed very less emissions as compared to conventional 100% Gasoline. The power & Torque has shown slightly more increase for conventional 100% Gasoline fuel as compared to other two Alternative Fuels. However, emissions were far lesser for water-Ethanol based micro-emulsion and Ethanol blended fuel. The main aim of this investigation is to reduce the emissions and trying to meet the future emission standards Euro 7.

Experimental Investigation of Performance and Emissions of Spark Ignition Engine Fueled with Blends of HHO Gas with Gasoline and CNG

Fossil fuels are widely used all over the world to power the motor vehicles. Due to superfluous consumption of these fuels, their reservoirs are depleting continuously. The huge demand of crude oil has caused the unprecedented price rise, environmental pollution, and global warming which directly affects the living beings as well as the surroundings in which they are surviving. Alternative fuels can suffice the demand with less adverse effects on the environment through the means of different sustainable technologies. Hydroxy gas (HHO) can be effective source of energy to combat these prominent issues. This work covers the experimental analysis of different parameters related to advantages and disadvantages of using HHO as a blend with gasoline and CNG fuel mixture. The analysis is based on engine performance and emissions. The experiments were performed on engine model fueled with a mixture of fuel and HHO gas. HHO was used as a fuel supplement. A compact HHO gas kit was installed in the engine compartment. A 219cc, four stroke, single cylinder spark ignition engine was used. No modifications were required in the engine design as HHO was used as a fuel supplement. The production of HHO was accomplished by the electrolysis of double distilled water in the presence of KOH(aq.) as an electrolyte. Products of water electrolysis consisted of H2 and O2 in the ratio of 2:1 by volumetric basis. Performance enhancement in overall engine characteristics such as brake power, specific fuel consumption, and overall efficiency was observed. Furthermore, a significant reduction in the emissions of unburnt hydrocarbons, carbon monoxide, and carbon dioxide was noticed. However, due to lean air-fuel mixture and tremendous peak combustion temperature the amount of NOx was increased.

Performance and emission characteristics of a single cylinder spark ignition engine fuelled by ethanol-H2O based micro-emulsion, blended ethanol, and CNG as an alternative fuel

In this work, the 15% ethanol blended with gasoline 85% micro-emulsions, and CNG were computationally investigated on one-dimensional simulation software AVL Boost for predicting the emission and performance of the single cylinder spark ignition engine. The engine properties taken for the single cylinder spark ignition engine are the same engine that is present in the lab as the constant speed single cylinder based generator. The water based emulsion fuel, which is prepared in the lab taking its composition as gasoline 85%, ethanol 15%, and H2O 5%, and the same composition was used in the AVL Boost Software. Finally, CNG was also used to check its emissions and performance on the same software and then was compared with the micro-emulsion and ethanol blended gasoline. This study explains how the three types of fuel performed on the same engine and predicted its performance and emission formation comparatively.
