摘要

In this study, the comparative effect of combustion and emission of Standard diesel engine and partially stabilised zirconia coated piston were investigated. Primarily three piston crowns were coated with Al2O3 (bond coat) of 100μm thickness each by using Plasma spray coating technique. Then these piston crowns were coated with Partially Stabilized Zirconia (PSZ) with a thickness of 250μm, 350μm, 450μm respectively by using the same technique over the bond coat. Then these three coated and one uncoated piston inserted into the cylinder one by one of a single cylinder, water cooled DI diesel engine. The result showed that on the application PSZ as a ceramic coating increased oxidation, which increases the generation of CO2. It has been also observed that coated piston engine increases the cylinder pressure and better heat release rate due to complete combustion.
