Аннотация:The major contributor of pollution in the environment has been because of the transportation sector. Compression ignition engine has been a popular engine in the transportation sector. Compression ignition engines have been very popular in the power plants and marine engine because of its high compression ratio. Compressors and reciprocating engine(cylinder-piston) are the mechanical assembly in an IC engine. Change in air fuel mixture in the cylinder improves the combustion and emission. Rising concern for the environmental emission, strict rules have been implemented because of which automobile manufactures have to modify the engine to suit better the emission standards. Depleting fossil fuels and rising emission standards, biodiesel blend has gained interest as an alternate fuel, for being used in CI engine. Biodiesel could be produced from waste and non-edible oils, shows similar properties to conventional diesel fuel. Waste cooking oil as biodiesel have gained interest in the researchers. Employing waste cooking oil biodiesel in a CI engine, it was important to analyses the effect on cylinder and piston. This paper analyses and compares the thermal effect of the waste cooking oil biodiesel with conventional diesel on the piston of a CI engine.
