Abstract
The main aim of this study is the experimental investigation of single cylinder DI diesel engine with and without coating. Diesel and radish (Raphanus sativus) oil Methyl Ester are used as fuels and the results are compared to find the effect of biodiesel in a thermal barrier coating engine. For this purpose, engine cylinder head, valves, and piston crown are coated with 100 μm of nickel-chrome-aluminium bond coat and 450 μm of TiO2 by the plasma spray method. Radish oil methyl ester is produced by the transesterification process method. From the experimental investigation, slight increase in specific fuel consumption in thermal barrier coating engine is observed when compared with the uncoated engine, whereas NOx, HC, Smoke, and CO emissions decreased with coated engine for all test fuels used in the coated engine when compared with that of the uncoated engine.
