Study on Performance & Emission Characteristic of CI Engine Using Biodiesel

Abstract

Biodiesel are extracted from transesterification process of edible and non-edible oil of vegetable and animal fat. It can be used in the diesel engine either in the form of neat oil or as a mixture of diesel fuel in the form of blend. The properties of oil are compared with the characteristic required for the fuel of internal combustion engine and the properties fuel are compared with conventional diesel fuel. Use of bio-diesel in a conventional diesel engine results in substantial reduction in unburned hydrocarbon (UBHC), carbon monoxide (CO), particulate matters (PM) emission and oxide of nitrogen. The blends of biodiesel with small content in place of petroleum diesel can help in controlling air pollution and easing the pressure on scarce resources without significantly sacrificing engine power and economy.
