Natural-gas-vehicle challenge: EPA emissions and fuel-economy testing, 1992. Technical report

The report describes the results of a student alternative fuels engineering design competition called the 1992 Natural Gas Vehicle Challenge which was held April 22 through June 1, 1992. Students from eighteen universities in the United States and four universities in Canada competed. The objective of this competition for each participating team was to convert a gasoline-fueled General Motors (GM) Sierra pickup truck to natural gas operation and compete with students from other universities in the areas of exhaust emissions, fuel economy, performance, and design. This report also includes the comparisons between the results of the student compressed natural gas pickup truck conversions and the test results of similar gasoline-powered trucks and a dedicated compressed natural gas truck provided by General Motors.
