Abstract

The compression ignition (CI) engines are most efficient and robust but they rely on depleting fossil fuel. Hence there is a speedy need to use alternative fuels that replaces diesel and at the same time engine should yield better performance. Accordingly, Dairy Scum oil methyl ester (DSOME) was selected as an alternative fuel to power CI engine in the study. In the first part, this paper aims to evaluate best fuel injection timing (IT) and injector opening pressure (IOP) for the biodiesel fuels (BDF). The experimental tests showed that DSOM yielded overall better performance at IT of 27o before top dead centre (BTDC) and IOP of 240 bar. In the second part, the effect of number of holes on the performance of BDF powered CI engine was studied keeping optimized IT and IOP. An injector of five holes with 0.3 mm orifice diameter yields better performance when engine powered with BDF at optimized conditions.
