Performance of UNDI Oil Biodiesel with Diesel in VCR Compression Ignition Engine under Variation in Engine Load & Compression Ratio

The world is facing many problems like energy, fuel, global warming and pollution. Petroleum diesel fuel which play very important role in the regular life for industries, transportation & any domestic sector, finding a suitable alternative (biodiesel fuel) to diesel is urgent need for this country. Undi based biodiesel is a non-edible fuel suitable for petrol & diesel engines. Transesterification process is used for preparation of Undi biodiesel. The physical & chemical properties of Undi biodiesel is nearly same as diesel. Experimental investigation of Undi oil has been carried out to analyze emission, performance characteristics in diesel engine with blends in diesel (0%, 20%, 40%, 60%) by changing compression ratio and engine load. The emissions from the diesel engine calculated with the help of smoke meter & gas analyzer. We can change compression ratio & engine load of diesel engine without any major modifications in variable compression ratio (VCR) diesel engine.
