A Single Cylinder Engine Study of Power, Fuel Consumption and Exhaust Emissions with Ethanol 2001-28-0029

In this study experiments were carried out to evaluate performance and exhaust emissions of carbon monoxide (CO) and hydrocarbons (HC) with ethanol-gasoline blends (15E and 85E) and gasoline in a single cylinder, 4-/changing parameters like engine speed, compression ratio, air-fuel ratio and ignition timing were studied in relation to engine performance and exhaust emissions. Effect of intake air temperature on engine performance was also studied. It was found that higher power output and improved energy efficiency were possible with ethanol gasoline blends as compared to gasoline at similar air-fuel ratios. At higher compression ratios engine performance was further improved with ethanol gasoline blends. An extended lean limit was observed which was favorable to obtain lower exhaust emissions.
