Title: EMISSIONS AND FUEL PERFORMANCE EVALUATION OF NATURAL GAS VEHICLES. FINAL REPORT, MAY-JUNE 1991
Abstract: Students of 24 North American universities designed and installed their own natural gas fuel systems on identical 1991 GMC Sierra pickups for the 1991 Natural Gas Vehicle Challenge student competition. Scoring criteria for the competition included emissions and fuel economy tests according to the EPA Federal Test Procedure (FTP), and a standardized cold start test. The report provides a description of these tests and the results. Emissions analysis included full speciation of the vehicles' hydrocarbon and aldehyde emissions. Estimates were also made of ozone formation potential of each vehicle's exhaust. The fleet of student-converted vehicles showed the potential of natural gas vehicles to produce lower non-methane hydrocarbon emissions and ozone formation potential than gasoline vehicles.
