Performance test on Diesel Engine by Changing Triangular Piston Crown

In internal combustion engines is one of the most important factors controlling the combustion process. It governs the fuel-air mixing and burning rates in diesel engines. The main drawback is incomplete combustion of fuel - air in a combustion chamber. This is due to emissions of pollution and the performance of the diesel engine become lowered. Hence it can be solved by modifying the piston crown configuration. The main objective of the paper is to reduce the emission and improve the performance level. The different emissions such as un burnt hydrocarbon (HC), carbon monoxide (CO), carbon dioxide (CO₂) etc. and the performance parameters are brake power (BP), indicated power (IP), frictional power (FP) and mechanical efficiency. The piston is modified by triangular shape on the crown, due to intensifying the air swirls for betterment of combustion. This configuration is compared to normal piston configuration, the experiments were conducted and compare the results values.
