Abstract | This volume of the two-volume report describes the heavy-duty, gasoline engine baseline emissions evaluations conducted at Southwest Research Institute. Initially, a facility was developed which was capable of complying with the requirements in the 1984 dynamometer transient procedure. Seventeen gasoline engines were then tested over the transient and the nine-mode emissions test procedures. Included were 1969 model year engines for HC baseline, 1972-73 engines for NOx baseline, and 1978-79 engines for correlation purposes. Emissions measured were hydrocarbons, carbon monoxide, and oxides of nitrogen on all engines. |
