Performance Analysis on 2.5 kW CI Engine Using Ethanol-Diesel Blends

Diesel engines are one of the major contributors of air pollution as they emits exhaust gases like particulate matter (PM), carbon monoxide (CO), nitrogen oxides (NOX); unburnt hydrocarbon (UHC) and other harmful compounds , which are very toxic for living beings as they can cause many diseases ,even cancer. They are even causing damages to our environment. So it is very important for us to switch to a cleaner fuel. Ethanol secures a special place as it has a lot of advantages over others. Most important reason for using alcohols is: it is cheap, renewable and echo-friendly. In very small blend percentage it has an ability to drive the existing CI engines without modifications. Many researchers’ have concluded that the brake thermal efficiency and brake power due to combustion process in diesel engines can be increased further by allowing the diesel fuel to combine with more oxygen atoms to form better combustion. As ethanol has oxygen atoms, when blended with diesel fuel it improves fuel characteristics. This whole process of addition of oxidants to the diesel fuel can reduce the smoke, carbon monoxide (CO) and unburnt hydrocarbon (UHC) emissions to a great extent. The objective of this research work is focused mainly on performance analysis of diesel engine by using diesel- ethanol blends. The tests are conducted with a single cylinder, four-stroke, naturally aspirated, 2.5 kW air cooled diesel engine. Present research work is focused on the test conducted on a diesel engine using diesel – ethanol blends by having 5% & 10% ethanol blend with diesel. The performance tests are carried out under normal engine operating conditions and the evaluations are compared with that of diesel fuel. All experiments have been conducted at 0% to 50 % load conditions to study the performance of different proportions of ethanol on CI engine. Overall results of the methods show that with the increase in percentage of ethanol in diesel fuel, highest temperature in cycle kept on decreasing also exhaust gas temperature goes on decreasing. Power developed and torque also increases with increase in percentage blend.

Modeling and performance analysis of diesel engine considering the heating effect of blow-by on cylinder intake gas

Recently, the stringent international regulations on ship energy efficiency and NOx emissions from ocean-going ships make energy conservation and emission reduction be the theme of the shipping industry. Due to its fuel economy and reliability, most large commercial vessels are propelled by a low-speed two-stroke marine diesel engine, which consumes most of the fuel in the ship. In the present work, a zero-dimensional model is developed, which considers the blow-by, exhaust gas bypass, gas exchange, turbocharger, and heat transfer. Meanwhile, the model is improved by considering the heating effect of the blow-by gas on the intake gas. The proposed model is applied to a MAN B&W low-speed two-stroke marine diesel engine and validated with the engine shop test data. The simulation results are in good agreement with the experimental results. The accuracy of the model is greatly improved after considering the heating effect of blow-by gas. The model accuracy of most parameters has been improved from within 5% to within 2%, by considering the heating effect of blow-by gas. Finally, the influence of blow-by area change on engine performance is analyzed with considering and without considering the heating effect of blow-by.

Theoretical Investigation of Combustion and Performance Analysis of Diesel Engine under Low Load Conditions

Diesel engine is using prominently in islands and remote areas due to its reliability and stability for power generation. In recent years, most of the isolated power systems (e.g., islands and remote areas) have integrated renewable energies to reduce both the cost and pollution in diesel power generating system. However, due to intermittent and stochastic behaviour of renewable sources (e.g., solar and wind), it is unable to eliminate diesel generation entirely. In that case, low-load diesel operation (operation < 30% of maximum rated load) is particularly relevant for its ability to support higher levels of renewable penetration. In this paper, a thermodynamic model was developed using MATLAB for diesel engine combustion and performance. This model includes sub models such as heat release rate, heat transfer, double-Wiebe function, and ignition delay correlation. Engine thermal efficiency (TE), brake power (BP), indicated mean effective pressure (IMEP) and brake specific fuel consumption (BSFC) has been taken into consideration for performance analysis. The simulation results show that at 25% load, in-cylinder pressure and temperature are 168 bar and 2300 K which are the cause of lower heat release rate (74 J/deg) and longer ignition delay (0.25 ∼0.5 ms higher than that of conventional mode) and significantly responsible for lower efficiency (18%), brake power (4kW) and higher brake specific fuel consumption (1.2 g/kWh).

Comparative performance analysis of diesel engine fuelled with hydrogen enriched edible and non-edible biodiesel

In the present study, a comparative analysis of enrichment of hydrogen alongside diesel fuel and two different sources of biodiesel namely rice bran oil is an edible oil, and karanja oil being non-edible is tested. Hydrogen at a fixed flow rate of 7 lpm is inducted through the intake manifold. A total of six fuel samples are considered: diesel (D), hydrogen-enriched diesel (D + H2), hydrogen-enriched 10, and 20% rice bran biodiesel blend (RB10 + H2 and RB20 + H2), and hydrogen-enriched 10 and 20% karanja biodiesel blend (KB10 + H2 and KB20 + H2). Results indicate that enrichment of hydrogen improves combustion and results in 2.5% and 1.6% increase in the brake thermal efficiency of diesel fuel and rice bran biodiesel, respectively. For karanja biodiesel the increment is negligible. Fuel consumption of the D + H₂ is 6.35% lower and for RB10 + H₂ and KB10 + H₂ it is decreased by 2.9% and 1.3%, respectively. The Presence of hydrogen shows the 4–38% lower CO emissions and 6–14% lower UHC emission due to better combustion. The blends RB10 + H₂ and KB10 + H₂ produce up to 6–13% higher NOx emission and that for the blends RB20 + H₂ and KB20 + H₂ it goes up to 25%. Overall rice bran oil is found to provide better performance than karanja biodiesel.

Experimental analysis of fuel properties and performance analysis of diesel engine with esterified castor oil blended with gasoline

As world is gone up against with double emergency of oil fuel exhaustion and ecological debasement, more prominent utilization of oil powers, high import cost of diesel and oil, expanded contamination has made biodiesel an appealing elective fuel to fulfill the future vitality needs. Biodiesel is an option in contrast to oil diesel, perfect, natural well-disposed and biodegradable fuel. As country is confronting a deficiency of eatable oil, it would not be practical to create biodiesel by palatable oils. Castor oil is non-eatable oil in this manner it opened a decent chance to think about its appropriateness to deliver castor biodiesel. The serious issue with castor oil was its consistency, which makes poor fuel atomization; carbon stores arrangement issues in the customary diesel motor. An outstanding base transesterification strategy was utilized for castor biodiesel creation utilizing methanol and NaOH. The fuel properties of castor biodiesel mix i.e. esterified castor oil in addition with petrol were studied and compared with petro diesel. In earlier studies mixing of biodiesel with diesel in various extents, for example, B10, B20, B30 were tried in diesel motor. In this present work, a test examination has been done in a single cylinder diesel engine at a consistent speed of 1500 rpm from zero load to 50% load to assess the performance qualities of esterified castor oil with petrol as biodiesel blends in three different proportionate.

Performance Analysis of Diesel Engine using Moringa Oil Methyl Ester with Fumigation Technique

The paper investigated the effect of 1-hexanol fumigation in an engine performance using Moringa biodiesel blend. In this research, the biodiesel used is processed from Moringa Olifera seed. In this research tests were performed with the modification of a CI engine to carburet the hexanol into the intake manifold. Initially the experiment was conducted with diesel and Moringa biodiesel (MOME25), and then the test was conducted with various proportions of fumigated hexanol along with MOBD25. Results revealed that, the BTE was increased by 1.08% for MOBD25 with 10% n-hexanol fumigation compared with other diesel and other proportions of fumigations with MOBD25 blend. The NOx emission and smoke were diminished by 36% and 38% respectively for MOBD25 with 30% n-hexanol fumigation. It is concluded that 30% n-hexanol fumigation with MOBD25 blend drastically reduce the NOx emissions with the penalty of BTE.

A facile preparation, performance and emission analysis of pongamia oil based novel biodiesel in diesel engine with CeO2:Gd nanoparticles

CeO2 and CeO2:Gd nanoparticles were synthesized by microwave assisted method and the samples were characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), Thermo gravimetric analysis (TGA), X-ray photo electron spectroscopy (XPS) analysis. Biodiesel was synthesized from pongamia oil using pre-synthesized CeO2 nanoparticles as heterogeneous catalyst and the obtained biodiesel was blended with diesel at different ratios. The CeO2 and CeO2:Gd nanoparticles were dispersed in blended biodiesel to analyse the emission from four stroke single cylinder Diesel engine with pure diesel and blended biodiesel. The blended biodiesel was characterized by Fourier Transform Infrared Spectroscopy (FTIR) and Gas Chromatography–Mass Spectroscopy (GC–MS). The physicochemical properties of blended biodiesel such as kinematic viscosity, flash point and acid value were measured using ASTM test methods and compared with biodiesel which was produced using conventional catalysts. From the performance analysis of diesel engine, it was observed that the pollutant emission relatively decreased in the CeO2:Gd dispersed blended biodiesel compared to pure diesel and blended biodiesel without ceria nanoparticles. The results of the present study revealed that the prepared pongamia based biodiesel using cerium oxide nano catalyst with CeO2:Gd nanoparticle dispersion can be considered as potential alternate fuel to the conventional diesel.

A Study on Chicken Fat as an Alternative Feedstock: Biodiesel Production, Fuel Characterisation, and Diesel Engine Performance Analysis

Biodiesel is one of the promising renewable sources to fulfill the future energy demand of the world. Sustainable feedstock for biodiesel production is one of the major criteria to ensure the process of renewability. Chicken fat is an encouraging feedstock for biodiesel. In this study, waste chicken fat was converted to biodiesel via catalysed transesterification. Optimised process parameters were recorded at 1:4 oil-to-methanol volume ratio and 0.5 wt% KOH catalyst concentration with a biodiesel yield of 96%. The FT-IR spectral analysis of chicken fat and chicken fat biodiesel confirmed the conversion of chicken fats into biodiesel. The physico-chemical properties of biodiesel were tested in accordance with ASTM D6751 and EN 14214 biodiesel standards. The specific fuel properties of chicken fat biodiesel that include calorific value, viscosity and acid value were found to be lower than that of petrodiesel. The diesel engine performance tests confirmed that the biodiesel blends performance was similar to petrodiesel. It is noted that while the brake horsepower increased with the increase of biodiesel blending percentage, the engine power output was found to decrease. Specific fuel consumption also increased along with the biodiesel blending percentage.

This work deals with the implementation of back propagation based artificial neural network (BPANN) model for prediction of the different diesel engine parameters, i.e., mean effective pressure, mechanical efficiency, fuel consumption, air-fuel ratio, and torque, to overcome the difficulties of practical experimentation and minimization of time and cost in this endeavor. The parameters provided as input to this model were engine speed, load and different biodiesel, and diesel fuel blends. The model has been trained with approximately 85% of the test results, and the rest were kept for prediction. The number of hidden layers and the number of neuron in each layer were varied to achieve the best predicting model. Once the model was ready, it had been used to predict the remaining data where the mean square error was as low as 6.51×10−4 and had a very low total R value. This work hereby shows that the BPANN based model can predict the performance of diesel engine fed with biodiesel and diesel fuel blends.
