Abstract

Swiftly developing industrialization, growing population, environmental threat, energy demands,have directed research towards alternative fuels. This experimental investigation aims todetermine the temperature distributions by coating on piston crown to analyze the effect of higherblends (B30 & B40) of Cashew nut shell oil (CNSO) diesel blends and studied the combustionbehavior. The thickness of the coating layer on the piston crown of the test engine are 500 ìm. Priorto coating, the surface of the crown area was grinded upto 500 μm so that the compression ratio ofthe existing engine continue to be the same. Then the mentioned parts were coated with 150 μmNiCrAl as a bond coat and thereafter same parts were coated with 85% of ZrO2and 15%Magnesium of 350 μm by plasma spray method. In this experimental work, single-cylinder 4-stroke compression ignition engine are used. The influence of coating thickness and distributionof temperature was investigated using the finite element method. Effect of combustion analysis,performance and emissions parameter are evaluated on the coated piston and compared with theuncoated piston. It was observed that BTE improved and CO, HC and smoke emission reducedsignificantly at maximum load, with increased NOX emissions.
