EXPERIMENTAL INVESTIGATION OF PERFORMANCE AND EMISSION ANALYSIS ON DIESEL ENGINE FUELLED WITH KARANJA OIL METHYL ESTER

The present research work is aimed to investigate the performance and emission characteristics of a Variable Compression Ratio (VCR) Diesel engine with karanja oil methyl ester (KOME) blend. An experimental work has been conducted on a four strokes, single cylinder water cooled diesel engine with a compression ratio of 17:1, 17.5:1 & 18:1 and 3.5 kW capacity. Blend (B) of KOME, B10 (10% KOME+ 90% Diesel), B20 (20% KOME+ 80% Diesel) and B30 (30% KOME+ 70% Diesel) biodiesel are used for conducting the test in diesel engine at different load conditions. Several parameters such as specific fuel consumption, thermal efficiency and emissions are recorded in a period of time. The noteworthy properties of KOME were related with the diesel to validate the experimental results. The experimental result shows that the fuel of B20 with the compression ratio of 18 can be used in diesel engines without any engine modifications.
