PERFORMANCE AND EMISSION CHARACTERISTICS OF YSZ THERMAL BARRIER COATED PISTON WITH VARIABLE EGR RATES AND RAPESEED OIL AS FUEL

The decreasing deposits of petroleum reserves and increasing risk of environmental pollution which is devastating the flora and fauna has become biggest concern. In order to address this one of the solutions is using alternate fuels which decreases the risk and is driving the researchers for a better biodiesel. This work is aimed at analysing the performance and emission characteristics of YSZ thermal barrier coated piston on Rapeseed oil B100 with EGR. It was found that at peak load conditions the emission of CO, CO2 and HC increases whereas the NOx emission decreases which sustains the functionality of EGR. By varying the rates of EGR i.e. 10%, 15% and 20% on coated piston for 20% at full load condition the maximum NOx reduction is observed.
