Alternative fuels such as LPG, CNG, hydrogen etc. have emerged as solutions to address depleting crude oil resources as well as deteriorating urban air quality. As a gaseous fuel, LPG has already been proven in terms of low emissions of carbon monoxide and hydrocarbon. The Government of India has taken an important and encouraging step towards the reduction of atmospheric pollution by directing its attention towards use of LPG as an automobile fuel. On Indian roads it has been found that, the vehicles that run on LPG have low compression ratio. It was also found that LPG could be directly retrofitted in existing gasoline fuelled engine and hence operating parameters such as compression ratio and ignition timing might affect performance and exhaust emission.
