Optimization of performance and emission characteristics of 7% YSZ coated diesel engine with biodiesel using Taguchi method

The primary analysis focuses on the impact of thermal barrier coated pistons on the efficiency and emission characteristics of diesel engines (CI). The test engine piston surface was coated with a 0.25 mm thick 7% YSZ top coat and a 0.05 mm thick Ni-Cr-Al-Y base coat using the plasma spray method. The tests will be carried out in a 4-stroke, 1-cylinder CI baseline engine utilise test fuels (Diesel, Mahua, and Jatropha) in both coated and uncoated tests. According to the analysis, a covered engine's BTE significantly improved by 2.7% and with a coated piston, the BSFC was lowered by 3.1%. In ceramic insulated engines, pollutants like HC and CO went lower by 6.9% and 6.5% respectively the NOx discharge was elevated by 11.9% validated to the base-line engine. The Taguchi strategy and response surface methodology were used to determine the optimal factor levels in terms of effectiveness and emission variables.

Control exhaust emissions of insulated diesel engine fuelled with biogas and cottonseed biodiesel

Gaseous fuels have many advantages than liquid fuels, as their calorific values of fuels are high, pollutants emitted by gaseous fuels are low and less dangerous when compared with liquid fuels. The drawbacks associated with use of vegetable oils in diesel engines such as high viscosity and low volatility can be reduced to some extent by converting them into biodiesel. However, they (biodiesel) cause combustion problems in diesel engine, due to their moderate viscosity, and hence call for low heat rejection (LHR) engine, which can burn low calorific value fuel, give high heat release rate and faster rate of combustion. The concept of LHR engine is to minimize heat loss to the coolant, thereby increasing thermal efficiency. LHR engine in this investigation consisted of ceramic coated diesel engine. They are many methods toinduct gaseous fuels such as port injection, carburetion technique, injection of gaseous fuel at the near endof compression stroke etc,. Investigations were carried out with biogas gas as primary fuel inducted by port injection and cottonseed biodiesel was injected into the engine in conventional manner, as India is second large producer of cottonseed oil in the world. Particulate matter (PM), oxides of nitrogen (NOx), carbon mono oxide (CO) levels and un-burnt hydro carbons (UBHC) are the exhaust emissions from a diesel engine. They cause health hazards, once they are inhaled in. They also cause environmental effects like Green-house effect and Global Warming. Hence control of these emissions is an immediate effect and an urgent step. The pollutants of PM, NOx ,CO and UBHC were determined at full load operation of the engine with varied injection timing such as recommended injection timing and optimum injection timing. NOx levels were reduced with provision of exhaust gas recirculation (EGR) at optimum flow rate of 10%. The maximum induction of biogas with conventional engine (CE) was 35% of total mass of biodiesel as full load operation, while it was 45% with LHR engine. Particulate emissions were determined by AVL Smoke meter, while other emissions were measured by Netel Chromatograph multi-gas analyzer at full load operation. These pollutants were drastically reduced with induction of biogas and further reduced with advanced injection timing. NOx levels drastically reduced with EGR.

Investigation of low heat rejection diesel engine run on N,N′‐diphenyl‐p‐phenylenediamine antioxidant doped Jatropha methyl ester‐diesel blend

AbstractLow heat rejection (LHR) diesel engines help increase engine performance and reduce engine emissions, but they increase air‐polluting nitrogen oxide (NOx) emissions. Different types of antioxidants or additives can be added to fuels to reduce NOx emissions and improve engine performance. In this investigation, N,N′‐diphenyl‐p‐phenylenediamine (DPPD) is used as an antioxidant. Different concentrations of DPPD namely, 500, 1000, 1500, and 2000 ppm are mixed with Jatropha Methyl Ester (JME)‐diesel blend (JME20), and the fuels are tested in an engine fitted with a TBC piston. The piston crown is coated using a mixture of Yttria‐stabilized zirconia (YSZ) and cerium oxide (CeO2) with a coating thickness of 0.3 mm. The novelty of this research work is the comprehensive assessment of the engine characteristics of an LHR diesel engine run on a synthetic antioxidant‐doped biodiesel‐diesel blend. Results indicate that the peak heat release rate (HRR) and the peak cylinder pressure are lesser by about 5.6% and 5.1% for JME20B4, respectively, at maximum engine load, in the coated engine (CE). The nitric oxide (NO), hydrocarbon (HC), and carbon monoxide (CO) emissions are reduced by about 6.5%, 17.4%, and 34.6%, respectively, at full load for the JME20B4 fueled LHR diesel engine. Smoke opacity decreases up to 15.3% in the coated diesel engine fueled with JME20B4 at full load.

Novel Scenedesmus obliquus algae biofuel emission and performance characterise in Si-DLC coated diesel engine

Investigation of the viability of providing biodiesel made from the algae Scenedesmus obliquus in a compression ignition (CI) engine. This research suggests Scenedesmus slick biodiesel (SOBD) as a possible source of energy, as it is found widely in marine, freshwater and aquaculture communities worldwide. SOBD was mixed with neat diesel fossil fuel at multiple volume ratios of 20 %, 30 %, 40 %, and its properties as a biofuel were analyzed according to ASTM standards. The characteristics study towards combustion, performance and emission of biofuel were analyzed by testing it on a single cylinder diesel engine at a 1500 rpm rated speed. The outcomes of the tests reveal that the efficiency of B20 (20 %SOBD + 80 % diesel) blend is comparable to pure diesel thermal efficiency, smoke, hydrocarbons and carbon monoxide. Still, the SOBD blend caused somewhat increased emissions of carbon dioxide and nitrogen oxides. At 100 % load, SOBD when compared with diesel achieves relatively lower cylinder pressures and lower heat release rates. In general, it is possible to deduce that the B20 blend (20 % SOBD 80 % diesel) will be a favourable feedstock variety that will be employed in unaltered combustion engines with minimal exhaust emissions.

The Effect of Thermal Barrier Coatings on Diesel Engine Performance

The performance of internal combustion engines should be improved depending on some technological requirements and rapid increase in the fuel expenses. On the other hand, the improvements in engine materials are forced by using alternative fuels and environmental requirements. Therefore, the performances of engine materials become increasingly important. For improving the performance of engine, thermal barrier coatings (TBCs) are a promising step forward. In this experimental study, alumina – (40 %) titania and nickel - chromium are used as the thermal barrier materials. The purpose of using these materials is to reduce the heat loss from engine. TBCs are done by atmospheric plasma spraying technique. Engine working conditions are maintained constant before and after coating. The results showed a reduction in specific fuel consumption. CO and HC emissions are slightly more than the conventional coated diesel engine at low and medium loads but lesser at higher loads whereas NOx is reduced.

Experimental Examination on Performance and Emission of a Coated Diesel Engine Fueled with Diesel and Pre-Heated Coriander Oil Blends

Abstract The aim of the study is to determine the effects of the preheated coriander seed oil, used as fuel, on the performance and the emission characteristics of the ceramic coated single-cylinder diesel engine. In this study, the piston, exhaust, and inlet valve of a single-cylinder air-cooled diesel engine were coated with Cr3C2 at 300 µm thickness. Pure coriander oil was mixed with diesel fuel volumetrically at the rates of 30% and 50%. The plasma spray method was used as the coating method. It was determined that the preheating process provided a more suitable fuel flow, decreased the viscosity of the coriander oil and also the coating process decreased CO, soot and HC emissions but increased NOx, thermal efficiency, and EGT.

Multi‐fuel performance and emission characteristics of an optimized thermal barrier coated diesel engine

AbstractOwing to the depletion of world oil reserves and increased environmental issues, engine modifications amid alternative fuels to improve performance are alluring a lot of attention nowadays. More than half of the total energy generated in the internal combustion engines are dissipated from the system through frictional losses, engine part cooling, exhaust, etc. The minimisation of these energy losses through heat transfer can improve the engine performance to an extent. The finest alternative for minimizing the energy losses through heat dissipations from the engine is with the use of thermal barrier coated (TBC) combustion chambers. In this paper optimum working condition of a single cylinder Kirloskar diesel engine with a ceramic thermal barrier coating (Yttria‐stabilized zirconia) on the piston was determined using Design of Experiments (DOE) software and predictions were validated experimentally. Further the multi‐fuel performance of a diesel engine with ceramic coated piston was also analyzed. The fuels used were diesel, pure biodiesel and optimized biodiesel blend B20. The optimum working condition was determined by using central composite design method in Design Expert‐7 software. The B20 fuel with TBC engine resulted to the maximum efficiency. Further it was validated experimentally by performing experiment at rated revolutions per minute (RPM) in a Kirloskar made single cylinder direct injection computerized diesel engine. Eventually a mathematical equation for the relationship between brake power, brake specific fuel consumption and brake thermal efficiency was derived using DOE software.

Experimental investigation of the effects of ethanol‐diesel mixture on the performance and emissions of the thermal barrier coated diesel engine

AbstractIn this study, the effects of thermal barrier coating (TBC) and diesel‐ethanol mixture fuel on carcinogenic and greenhouse‐causing harmful emissions from diesel engines were experimentally investigated. In the first stage, the combustion chamber parts of the single cylinder diesel engine were coated with ceramic Al2O3TiO2 material with low thermal conductivity. Plasma spray method was used as the coating method. Then, coated and uncoated engines were run on diesel fuel. In the second stage, ethanol‐diesel mixture containing 5% ethanol E5 (v/v) was used in both engines. In both stages, the engines were operated at full load and at different engine speeds and compared in terms of emissions and performance. Combustion improved as the effect of the increased in‐cylinder temperature thanks to the low heat transfer with TBC. Therefore, an increase in engine power occurred. However, when E5 fuel was used in the TBC engine, the engine power decreased slightly. In the coated engine, HC and CO emissions have been significantly reduced. NOx emission increased with the effect of the thermal barrier coating, but decreased by 18% with the addition of ethanol in the TBC engine due to lower calorific value of ethanol.

Investigating the Performance, Reduction of Emission and Combustion Characteristics of YSZ Coated D.I.Diesel Engine Powered by Binary Bio-fuels

Performance, emission and combustion studies were carried out on the ceramic coated diesel engine (YSZ) fed with biodiesel obtained from the oil derived from the mango seeds (MSBD) and MSBD blended with turpentine oil (MSBTO). The performance study showed that the MSBD and MSBTO blends showed 3.6% and 7.1% more BSFC value compared to that of DF in ceramic coated engine due to higher density and viscosity. The maximum brake thermal efficiency was observed 28% for DF in coated engine compared to other fuels due to less fuel consumption of DF because of lower density. The emission characteristics displayed that the MSBTO fuel showed 12%, 15.2% and 29.1% reduction in the smoke density, NOx and CO respectively compared to that of DF in coated engine. However, the MSBD and MSBTO showed 17 and 21% more release of UBHC at full conditions compared to that of DF in ceramic coated engine due to lesser calorific values of MSBD and MSBTO compared to the calorific value of DF. Combustion study revealed that the MSBD and MSBTO displayed less cylinder pressure compared to that of DF in coated engine and the MSBTO fuel showed the 5.3% decrease in the cylinder pressure compared to that of DF in coated engine owing to less heat liberation and lower cetane value. HRR followed the similar trend of variation of cylinder pressure and the MSBTO displayed 7.4% lower HRR compared to that of DF in coated engine.

The exhaustive nature of petroleum products triggers the obstacles of scarcity, economic imbalance, and environmental depletion. It is difficult to avoid their usage all of a sudden and switch to clean electric prime movers. Under all these circumstances, the researchers may initiate their investigations on alternative fuels for preeminent solution. The present study covers the performance and emissions of a single cylinder, four‐stroke, diesel engine fueled with Pongamia pinnata and Calophyllum inophyllum biodiesels added with n‐butanol additive at various proportions. In this investigation, the piston has been coated with ceramic material with a thickness of 200 µm topcoat. The blends have been tested at 1500 rpm speed and rated compression ratio of 17.5 : 1 at various operating loads. A comparative result analysis has been made on the engine parameters operated by diesel and showed that mechanical efficiency gradually increases with a percentile increment of n‐butanol in the blend. Moreover, emissions such as CO, CO2, NOx, and opacity were found to be reduced for the samples having high amount of n‐butanol, whereas HC emissions slightly increased. In addition, all the exhaust gases have been predicted by using second‐order polynomial equations generated and artificial Intelligence technique, and the comparative analysis has been made. It has been identified that ANN showed an average accuracy of prediction superior than regression analysis.

An experimental study on harmful pollution reduction technique in low heat rejection engine fuelled with blends of pre-heated linseed oil and nano additive

The number of energy users in the world is growing more significant and more prominent in the current scenario for the automotive sector. About 70% of India’s energy depends heavily on non-renewable fossil fuels. The cost and demand for the fuel are incredibly high. Over and above these reasons, environmental pollution is causing great concern. Consequently, many of the present researchers are focusing on finding a renewable fuel that can become an alternative for fossil fuel that is fast depleting. Biodiesels have drawn much attention from the research community because of their natural characteristics and chemical composition. In this manuscript, we have reported the linseed oil, which is effectively used as biodiesel (B20) and pre-heated to decrease the viscosity of the fuel with the aid of heater up to 100°C. The nanoparticle used in this work is titanium dioxide because of its highest oxygen content and easy availability in the market. Different proportions of titanium dioxide nanoparticles are blended (50 ppm, 100 ppm, 150 ppm, and 200 ppm) with pre-heated linseed oil in a coated diesel engine. The coating material used is Partially Stabilized Zirconium and the preferred thickness of 0.5 mm that is achieved with plasma spray techniques guidance. The crown of the piston or the top surface of the piston is coated with Partially Stabilized Zirconium (PSZ). It is observed that pre-heated PLSNP200 linseed oil has shown the enhanced performance and lower emissions when correlated with all the other blends. Pre-heating of Linseed oil and diesel engine (DI) coating has resulted in a 5.2% increase in thermal efficiency. The combination of PLSNP 200 reduces emissions of CO, smoke, and HC by 37.78%, 25%, and 37.92%, respectively. The oxides of nitrogen are elevated drastically by 7.43% when correlated with diesel fuel. The blend PLSNP200 increased the BTE and NOx by 8.11% and 6.53% respectively when compared with PLS20. The PLSNP200 blend HC, CO and Smoke opacity emission is drastically decreased by 33.82 21.05% and 26.57% when compared with the preheated linseed oil B20 (PLS20).

Модифицированный квазистационарный метод изучения изменения температур перехода поршней дизельного двигателя, покрытых теплозащитными материалами

The purpose of the work is to identify complex transient heat flow paths in the combustion chamber of engine, significantly improve the models of diesel engine heat flow, and study the effect of aluminum oxide coating by the galvanic plasma method on short-term and long-term reactions of the piston head. The analysis of operation of aluminum alloy coated diesel engine piston is carried out using a modified quasi -steady method and a finite element method. A thermodynamic analysis is presented using energy and state equations with corresponding gas heat transfer. Time-dependent boundary conditions are set on the gas-blown surfaces of 2D finite element transition models of combustion chamber components. It is shown that this methodology can reveal complex transient paths of the heat flow in engine combustion chambers and distribution details of heat losses in various cooling media. Numerical simulation has shown that the maximum temperature increase relative to the uncoated piston is 64.3% for the coating thickness of 0.13 mm. Tests have shown that the coatings can endure up to 280 thermal cycles. It is found out that predictions of numerical simulation are in good agreement with the results of experiments conducted with repaired pistons. The experimental operation of Cummins КТА 38 engines at Chernogorsk and Vostochno-Beysk coal mines has shown that the engine equipped after repair with the piston coated with aluminum applied by the galvanic plasma method has been in operation for 2 years and 3 months, whereas its set overhaul period is 18,000 hours. Therefore, the proposed methodology allows to reduce temperature variations in the piston and, thereby increase the service life of engine pistons coated with the use of the thermal barrier coating technology.

Oxygenated fuel additives and thermal barrier coating (TBC) applications are noteworthy subjects that may reduce the exhaust emission levels and improve the performance of vehicles. In this study, the exhaust emission and performance characteristics of chromium oxide (Cr2O3) coated single cylinder diesel engine fueled with dibutyl maleate (DBM) blends were investigated. In addition, an artificial neural network (ANN) which had the ability to reduce experimental repeats, cost and time loss was designed and its performance was examined. Piston crown and valves of diesel engine were treated with chromium oxide. Experiments were carried out with DBM3, DBM6, DBM9 blends that contain 3%, 6%, 9% by volume of DBM, respectively. The results indicated that carbon monoxide (CO), hydrocarbon (HC), smoke density, brake specific fuel consumption (BSFC) values reduced in the isolated engine (IE) whereas nitrogen oxide (NOX), exhaust gas temperature (EGT) and engine vibration (EV) values increased compared to standard engine (SE). The addition of DBM reduced CO, HC, smoke density, EGT, and engine vibration whereas NOX and BSFC values increased in both IE and SE. Consequences of ANN revealed that exhaust emission and performance attributes of an engine can be estimated with high accuracy.

The performance and emission affected by piston catalytic coating have been analyzed in this study. The main contributing factors for improving performance such as load, fuel and speed have been preferred to reduce the emission and improve the performance of an IC engine. These specific standard parameters have been modified with copper alloy coated diesel engine with the aid of design of experiment by Taguchi with grey relational analysis optimization (GRA) method, for improving the IC engine performance and reducing the emissions.

The present work give emphasis to investigate the exergy and energy analysis of 20% pomegranate seed oil methyl ester with engine operating parameters modification at thermally coated engine. The present work intends to find the optimum engine operating parameters in ceramic coated diesel engine. The engine was initiated with diesel as a working fuel. Followed by, the conventional engine was allowed to work with pomegranate seed oil methyl ester at standard compression ratio, injection timing and injection pressure. The engine operating conditions were altered in 5.2 kW, 1500 rpm, single cylinder water-cooled direct injection engine.

From the results, it was observed that the biodiesel sample showed significant engine characteristics at high compression ratio, injection pressure and injection timing in thermally coated engine. In addition, the aforesaid combination offered a considerable performance in thermodynamic analysis of biodiesel sample in both conventional engine and thermal barrier coated engine. The practice of using pomegranate seed oil methyl ester (B20) with engine operating parameters modification in Yttria Stabilized Zirconia coated engine may be considered as the advantageous approach to achieve better engine characteristics.

Operational evaluation of thermal barrier coated diesel engine fueled with biodiesel/diesel blend by using MCDM method base on engine performance, emission and combustion characteristics

In this study, engine operating conditions which given the best result in terms of performance, exhaust emission and combustion characteristics in a thermal barrier coated (TBC) diesel engine, which was covered with ceramic on combustion chamber elements, were determined by multi-criteria decision-making (MCDM) method. It was also included in the optimization of the data obtained from the uncoated (standard) engine (STD) in order to better evaluate the TBC engine. In the experimental study, diesel, pure biodiesel derived from cotton oil frying waste and biodiesel/diesel blend fuels (5, 20 and 50% by volume) were used as fuel. In optimization, operational competitiveness rating (OCRA) was preferred as a MCDM. The experimental data, which included a total of six hundred data, in TBC and STD engines fueled biodiesel and its blends were used in optimization. According to the optimization result, the best results in terms of engine performance, exhaust emission and combustion characteristics were generally obtained from the TBC engine. According to the optimization sequence, the ranking obtained from the TBC engine were observed to be ahead of the STD engine at all engine speeds. It was also found that the best results were concentrated at engine speeds of 1800 rpm and 2100 rpm. The best result was achieved by using B20 (20% biodiesel + 80% diesel) in TBC engine at 1800 rpm. The performance, emission and combustion characteristics obtained under these optimum operating parameters (OOP) were also compared with those of the STD engine fueled with B0 and B100.

Investigation of using pumpkin seed oil methyl ester as a fuel in a boron coated diesel engine

In this study, pumpkin seed oil was converted into biodiesel using alkali-catalyzed transesterification. Physicochemical properties were examined based on ASTM standards and compared with commercial diesel fuel (D-2). To improve the performance of engine, combustion chamber components like piston head, cylinder liner, intake and exhaust valves were thermally coated. Boronizing method was applied for the first time in the coating of conventional cast iron cylinder liner surface to reduce heat transfer. 150 μm thick Fe2B layer was deposited on the surfaces. So, the conventional engine was converted into low heat rejection engine. In order to determine the insulation affect of Fe2B layer, 3-D finite element transient-state analyses were done to the both coated and standard cylinders. D-2 and PSME fuel blends were used as test fuels. Emission and performance of the coated engine (CE) have been investigated for both fuels. CE showed lower emission and higher performance. For D-2 and B-20 fuels; results showed that, CO decreased by 13–15%, HC decreased by 53–36%, smoke density decreased by 15–36%, respectively. But NOx emission increased by 11–37% for D-2/B-20 fuels, respectively. Besides, BTE for D-2/B-20 fuel increased by 10-10% while BSEC decreased by 3–9%, respectively.

Performance and emission properties of preheated and blended fennel vegetable oil in a coated diesel engine

The use of crude fennel seed oil in a diesel engine, whose combustion chamber was thermally insulated, with diesel fuel at specific rates was investigated in the present study. A single-cylinder air cooled diesel engine was used as the test engine. Plasma spray method (coated with Cr3C2 in a thickness of 300 µm) was used as the coating method. Since the atomisation and vaporisation of fennel oil are highly affected by the physical properties of the fuel, a preheating process of 100 °C was applied. Crude fennel oil mixed with diesel fuel at 30% and 50% by volume. It was shown that a preheating process of 100 °C provided a proper fuel flow and reduced the viscosity of the funnel oil and additionally, the coating process decreased carbon monoxide (CO), smoke, and hydrocarbon (HC) emissions but increased nitrogen oxides (NOx), thermal efficiency, and exhaust gas temperature (EGT).

Performance and emission characteristics analysis of thermal barrier coated diesel engine using palm biodiesel

Various research works are being undertaken around the world on the subject of thermal efficiency improvisation and emission reduction from diesel engines. This research work analyzes the performance and emission characteristics of a thermal barrier coated diesel engine which used palm biodiesel. The piston and cylinder liners were coated with equal percentages of alumina (Al2O3) and yittria-stabilized zirconia (YSZ) powder using plasma spraying coating method. The piston was coated with 100μm thickness and the two cylinder liners were coated with 150 and 200μm thicknesses and were used to analyze the performance and emission characteristics. Test results of the thermal barrier coated engine using palm biodiesel were compared with the results derived from the base engine. The tests revealed an increase of 3.8% specific fuel consumption (SFC) as an average when neat palm biodiesel was used in the base engine. Interestingly, the palm biodiesel used in the 150- and 200-μm thick thermal barrier coated engine was responsible for a significant decrease of the SFC by an average of 4.18% and 8.05% respectively. The brake thermal efficiency was found to decrease on an average of 1.02% when tests were run using the neat palm biodiesel in the base engine. But an average proportionate increase of 0.72% and 2.19% was visible when palm biodiesel was used in the tests conducted on the 150- and 200-μm thick thermal barrier coated engine. There was also an understandable brake specific reduction of 0.991g/kWh carbon monoxide (CO) emission and 0.025g/kWh unburned hydrocarbon (HC) levels. The nitrogen oxide (NOx) emission was observed as 14.06g/kWh in the 200-μm thick thermal barrier coated engine which was slightly higher when the results were compared with that of the uncoated engine. The novelty of this research investigation is based on the usage of yttrium-stabilized zirconia and alumina thermal barrier coating on the cylinder liner and piston head of engine. This is justified due to the fact that most of the previous investigations undertaken focused on the thermal barrier coating in the piston, valve, and cylinder head alone. The utility factor of the palm biodiesel (B 100) in the low heat rejection engine has also proved to be another significant and novel factor in the present investigation outlined in this paper. This is mainly due to the fact that the ongoing investigations in this realm concentrated only on blends of 20 to 30% of palm biodiesel with diesel fuel in the low heat rejection diesel engine.
