Abstract: With the depletion of fossil fuel resources and increase in pollution level leads to researches to concentrate much for the development of renewable fuels for the existing diesel engines. Currently more than 95% of the biodiesel is produced from edible oils. Producing biodiesel using edible oil may leads to shortage towards eatables and also increases in the cost. Nonedible oil is the alternative to solve this problem. But any alternative fuel which finds suitable as substitute to diesel is comparatively inferior to diesel in performance, emission and combustion characteristics. To bridge this gap various technologies are developed. However in this work an attempt will be made to enhance and optimize fuel properties like pour point, flash point, cloud point, viscosity etc. This can be carried by two means. They are LHR engine concept and turbocharger. In diesel engines maximum amount of heat is lost to cooling medium. For better performance of the engine, improved combustion, reduced emissions, temperature and pressure of in cylinder are responsible which are controlled by cooling rate. Under these circumstances, material selection of components is the main criteria. One of the most promising ceramic materials known for its low density, high thermal stability in severe chemical environments is mullite. Further low thermal conductivity, strength and creep behaviour of this material are also suitable.100 microns and 500 microns thickness mullite thermal barrier coating on the piston head is to be considered for experimental purpose. The density of air entering the cylinder decreases in the insulated engine. Thus the volumetric efficiency of the LHR engine decreases. Turbocharger will be used in order to increase the volumetric efficiency and engine output.
