Performance and Emission analysis of Multi-Cylinder Common Rail Direct Injection Diesel Engine Powered with Blends of Tyre Pyrolysis Oil-Ethanol-Diesel

Abstract

This paper mainly focuses on optimal replacement of diesel by Tyre Pyrolysis oil-Ethanol blends to run a common rail direct injection (CRDI) multi cylinder engine and to compare the results with neat diesel fuel operation results at 1500 rpm. The engine was operated at different loads and speeds. From the experimental study, decrease in brake thermal efficiency (BTE) and oxides of nitrogen (NOx) emission with increase in carbon monoxide (CO), hydrocarbon (HC), and smoke emission was observed for blends as compared to diesel fuel. Further, it was also observed that increase in speed from 1200 rpm to 1800 rpm yielded higher BTE with decrease in CO, HC and smoke emission. But slightly increase in NOx, peak pressure (PP) and heat release rate (HRR) was reported at higher speed as compared to lower speeds. Beyond engine speed of 1800 rpm, knocking was observed.
