Experimental Analysis of Emissions in a 4S Diesel Engine Blended with Refined Vegetable Oil

Abstract

In the scenario of fossil fuels and in ever depleting, there is always a scope for alternative fuels and this paper aims to study blends of diesel with Refined corn oil (BRC) on a stationery engine. The experiment is done on krisloskar Direct injection 4 stroke diesel engine, single cylinder, air cooled 4.4 kW constant speed at 1500 rpm with an compression ratio 17.5:1. Methyl esters of BRC were transesterified with sodim meth oxide before blending with diesel. For different blends at diesel (10%, 30%, 40%) in volume at specific injection pressures ( 180bar, 210 bar and 240bar) against different loads (0%, 25%, 50%, 75%, and 100%) have been tried in the experiment to study NOx, CO, HC, Smoke emissions with exhaust temperature. A 3- hole nozzle has been used and the emission are analyzed with AVL gas analyzer. Even though marginal increase in NOx with exhaust temperature at higher temperature are noticed the decrease in engine temperature by 3 deg in addition to HC and CO an significant.
