Experimental Investigation of YSZ Coated Piston Crown on Performance and Emission Features of LHR Diesel Engine with Mahua Biodiesel

Abstract

Researchers have carried out numerous studies on low heat rejection (LHR) engines. Among the studies reported, some are experimental and many are theoretical in nature. The thermal barrier coatings (TBC) play a prominent role in LHR engines. Ceramic coatings are TBCs, they shield the base material and high temperature protect the source. The present work is focused on Yttria-stabilized zirconia (YSZ) material with a thickness of 500 microns. Is a bond coat which is used a plasma spray Tanique for costed on the required surface. Experimental analysis is carried out on a diesel engine with diesel and Mahua biodiesel with different loading conditions. This study results to expose that brake thermal efficiency is bigger along with lessening of BSFC. The LHR engine reduces the Hydro carbon (HC) and carbon monoxide (CO) emissions drastically but the Nitrogen oxide (NOx) emission is increased.
