Performance, Emissions and Combustion Characteristics of a Single Cylinder Diesel Engine Fuelled with Blends of Jatropha Methyl Ester and Diesel

Performance, Emissions and Combustion Characteristics of a Single Cylinder Diesel Engine Fuelled with Blends of Jatropha Methyl Ester and Diesel

ABSTRACT: In order to meet the energy requirements, there has been growing interest in alternative fuels like biodiesels, ethyl alcohol, biogas, hydrogen and producer gas to provide a suitable diesel substitute for internal combustion engines. An experimental investigation was performed to study the performance, emissions and combustion characteristics of diesel engine fuelled with blends of Jatropha methyl ester and diesel. In the present work three different fuel blends of Jatropha methyl ester (B10, B20, B40 and B100) were used. The increments in load on the engine increase the brake thermal efficiency, exhaust gas temperature and lowered the brake specific fuel consumption. The biodiesel blends produce lower carbon monoxide & unburned hydrocarbon emission and higher carbon dioxide & oxides of nitrogen than neat diesel fuel. From the results it was observed that the ignition delays decreased with increase in concentration of biodiesel in biodiesel blends with diesel. The combustion characteristics of single-fuel for biodiesel and diesel have similar combustion pressure and HRR patterns at different engine loads but it was observed that the peak cylinder pressure and heat release rate were lower for biodiesel blends compared to those of diesel fuel combustion.

Influence of injection timing and compression ratio on performance, emission and combustion characteristics of Annona methyl ester operated diesel engine

Influence of injection timing and compression ratio on performance, emission and combustion characteristics of Annona methyl ester operated diesel engine

4.3. Effect of compression ratio on performance, emission and combustion characteristics 4.3.1. Specific fuel consumption (SFC) Fig. 11 shows variations of specific fuel consumption for dif- ferent compression ratios and for A20 blend when compared to that of neat diesel fuel. 19.5:1 of compression ratio gives lowest SFC as compared to all other compression ratios and neat diesel fuel. The specific fuel consumption of the A20 blend at the compression ratio of 19.5:1 is 0.30 kg/kW h whereas for diesel it is 0.32 kg/kW h. This is due to the fact that increase in compression ratio reduces BSFC due to reduction in dilution of charge by residual gases, which results in better BTE and lower BSFC. However increase in BSFC is observed with lower compression ratio due to slow combustion pressure because of more charge diameter and lower compression pres- sure and temperature.

Study the Performance of Algae Oil in Diesel Engine with Various Injection Pressure

Study the Performance of Algae Oil in Diesel Engine with Various Injection Pressure

--------------------------------------------------------------------------------------------------------------------------------- Abstract - In the recent years, vehicle population increased enormously which increases the demand of fossil fuel. The availability of crude oil supply decreases continuously, these reasons makes the researchers to find new renewable alternative fuel especially biofuels. Some of the vegetable plants like neem, karanja, rapeseed, jatropha, soabean, etc. were already found as successful production of biodiesel. But the problems in these sources were the land availability. Still, it has been reported that the use of biodiesel considerably reduced emission and increase the performance of the engine. The most promising method for the production of biodiesel is transesterification process. Now-a-days researchers have reported the possibility for the production of biodiesel from algae oil because of its high lipid content in nature. In the present study, algae methyl ester is used as the biodiesel in the direct injection (DI) diesel engine. The general optimum biodiesel blend AME20 (diesel 80% and algae methyl ester 20%) was taken for the experiment. The injection pressure of the engine has been varied from 210 bar to 230 bar in the steps of 10 bar. The result of experimental investigation reported that the change in injection pressure with AME20 shows the better performance in the diesel engine as well as reduced the emission characteristics.

Effect of Various Injection Pressures on Performance and Emission Characteristics of a Four Stroke CI Engine Fuelled With Algae Biodiesel

Effect of Various Injection Pressures on Performance and Emission Characteristics of a Four Stroke CI Engine Fuelled With Algae Biodiesel

Now a days in diesel engines the fuel injectors are designed to maintain very higher injection pressures in order to acquiring better performance results. The main intention of this design is decrease the exhaust emissions and increasing the efficiency of the engine. The fuel injection pressure is inversely proportional to the droplet size of the fuel. The fuel droplets diameter is increases at lower injection pressures then the ignition delay period is increases during the combustion. This further leads to increase the injection pressure. Engine performance will be reduce since combustion process goes to poor condition. When injection pressure improved the fuel particle size decreased. The air and fuel mixture formation becomes better from that complete combustion was done in the cylinder during the period of ignition. When injection pressure is high the ignition delay period is shorter. The homogeneous mixture is leads to increase in combustion efficiency.
