| Summary: | In general the diesel combustion and its performance is based on the wear and the ceramic coating. In this paper the engine used is four stroke single cylinder diesel engine wind the fuel used for combustion is a biofuel which is the result of blending the jatropha seed oil with that off methyl ester. Since the biofuel tends to harsher on the piston which inturn affect the performance of the engine the piston are suggested to be coated with Cr3C2-PS. ZrO2 powders which acts as a thermal as well wear resistance barrier on the piston. Jatrophai organic diesel mineral is used as a blend to test diesel engine combustion and output properties. With specific loads 0%, 25%, 50%, 50%, 100% for both coated and uncoated pistons, the experimental tests on the combustion characteristics of heat escape, peak strain, inflammatory delay and thermal brake performance are tested. Due to esterification (10–20% by volume), the organic diesel blends prepared from jatropha are made. Here the jatropha bio diesel blends are used in the diesel engine whose results states that the performance of the piston coated engine is highly strengthened for about 10% than that of uncoated piston engine. Thus the cylinder pressure is improved to 20% JME in contrast with that of uncoated piston with a compression ratio of 17.5 respectively. Thus proving that the wear resistance of coated piston tends to shift by 47% to overall reduction wear rate of 35%. |
