Numerous vegetable oils suitability has been investigated for use in internal combustion engines. The effects of different fuels on the performance characteristics of engines have been extensively reported. The high viscosity and low volatility of these vegetables oils are the major problem for their use in the diesel engines. However use of different biodiesels in an engine results in variability in the engine performance and emission due to physical and chemical characteristics of fuel. The effect of these physio-chemical properties on fuel supply system such as fuel pump and fuel filter have already been reported.
In this work an attempt is made to improve the combustion characteristics of the engine fueled with biodiesel. Hence a detailed investigation is carried out on the underlying combustion and heat release characteristics. The experimental work is conducted on 4S, single cylinder, water cooled and DI stationary diesel engine. In this work bsfc and thermal efficiency are computed, for different incylinder pressure and peak heat release rate.
