Investigation of Performance and Emissions with Low Level Ethanol-Gasoline Blends on a Passenger Car

Ethanol blended gasoline has offered new opportunities in Indian automotive industry. Ethanol (5%) blending in gasoline is already commercially implemented in many states of India. The steep increase in crude oil prices and depleting oil resources has forced the government and Oil Marketing Companies (OMC) to look forward to the implementation of 10∼20% ethanol-gasoline blend in future.

Before implementation of the 10% blend, the effect of ethanol-gasoline on vehicle performance and emissions are need to be studied. This paper investigates the performance of vehicle in terms of fuel economy, cold and hot start ability, power performance and emissions performance (Type-I and IV) of gasoline passenger car with 5% and 10% ethanol-gasoline blends.
