Environmental pollution from engine exhaust emission has attracted worldwide attention. Besides vehicular pollution, the significance of engine exhaust emission from stationary utility engines, particularly gensets for electrical energy applications, has also been realized. Gensets based on kerosene are widely in use in developing countries like India. To reduce the exhaust emission, from these small carbureted engines is challenging due to cost factor. In present work, an attempt has been made to reduce the exhaust emission of a portable genset by blending alcohols in kerosene. It was observed that blending alcohols in kerosene helps reducing Carbon Monoxide (CO) and Hydrocarbon (HC) emission and fuel consumption of the engine while Nitric Oxide (NO) emission increases. Further, the effect of varying carbureted jetsize on the performance and exhaust emission is also examined. A comparison of kerosene with base jetsize was done with the various combinations of fuels and jetsizes to achieve optimized emission and fuel economy. It was observed that by blending 10% n-butanol in kerosene and operating engine on a slightly richer side, emission from a kerosene operated genset can be reduced along with improvement in fuel economy without any engine hardware modification.
