Emissions Performance of Bi-fuel CNG and Bi-fuel LPG Passenger Cars Using Sequential Multi-point Injection Systems 2001-01-1195
This paper describes a study into the emissions performance of a passenger car running on natural gas and liquified petroleum gas. The gasoline engine was modified to allow the introduction of the alternative fuels into the engine. The effect of fuel system hardware on emissions was investigated. Modifications were carried out to the gasoline EMS to allow control of the alternative fuel systems. A number of changes were made to the gasoline calibration to allow operation on the alternative fuels. Emissions tests were conducted on commercial grade natural gas and liquid petroleum gas. The results were compared with gasoline emission results of an equivalent vehicle.
