Investigation of Bio-Diesel in Uncoated Piston Head Vs Bio-Diesel in Coated Head

The need for less carbon content in fuel, as well as an increase in energy consumption, has paved the way for the development of alternative fuel for engines. Biodiesel is an environmentally friendly alternative to conventional fuel. Thermal barrier coating reduces heat transfer to the cooling system while the engine is idle and protects engine components from high thermal stresses. This paper investigates the blending of waste fish fry methyl esters in a single cylinder, four stroke DI diesel engine with a stellite-6 coated engine head. In this study, waste fish fry oil (WFFO) was transesterified with methanol and a NaOH catalyst. The methyl esters were obtained, and various test fuels were made (WFFO10, WFFO20, WFFO30) These blended samples were fired up in the DI diesel engine, and performance tests were conducted. Engine characteristics such as brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), and engine emissions were measured for the stellite6 coated cylinder head.
