Performance characteristics of automotive engines in the United States. First series. Report No. 13. 1975 American Motors, 258 CID (4. 2 liters), 1V

Experimental data were obtained in dynamometer tests of a 1975 AMC 258-CID production IV engine to determine fuel consumption and emissions (hydrocarbon, carbon monoxide, oxides of nitrogen) at steady-state engine-operating modes. The objective of the program is to obtain engine-performance data for estimating emissions and fuel economy for varied engine service and duty. The intent of the work is to provide basic engine characteristic data required as input for engineering calculations involving ground transportation.
