Abstract
This paper investigates performance and emissioncharacteristics of a two stroke petrol engine.A single cylinder two stroke petrol engine was used for the experiments at various speeds. An a EUROGAS model 8020 gas analyser and a smoke meter were used for the measurements of exhaust gas emissions. Engine performance (brake power, indicated power, brake mean effective pressure, mechanical efficiency, brake specific fuel consumption, volumetric efficiency, brake thermal efficiency and air–fuel ratio, and emissions (carbon monoxide, carbon dioxide, hydrocarbons, nitrogen monoxide and oxygen), were measured to evaluate and compute the behaviour of the two stroke petrol engine running on blends of petrol and lubricant oil without and with jatropha biodiesel and ethanol. The results showed that the best value among the blends of the brake power, indicated power, brake mean effective pressure, mechanical efficiency, hydrocarbons emissions and nitrogen monoxide in the blend (98%petrol and 2% lubricant oil), the best value of brake specific fuel consumption, brake thermal efficiency, air–fuel ratio in the blend (94% petrol, 2% jatropha biodiesel, 2% lubricant oil and 2% ethanol), the best value of carbon monoxide, carbon dioxide and oxygen emission in the blend (92% petrol, 4% jatropha biodiesel, 2% lubricant oil and 2% ethanol).
