Abstract

This was a two-part study effort. In the first part, an evaluation was made of vehicle simulation computer programs to determine and select the best program for EPA use in conducting various analyses of automobile fuel economy and emissions effects. The programs considered were (1) a DOT simulation routine called VEHSIM, (2) a program developed by the University of Wisconsin, and (3) a program developed by The Aerospace Corporation. The DOT VEHSIM program was picked primarily because it provides exceptional flexibility and ease of operation, and because it appeared to be readily adaptable to modifications required for the analysis of timing and carburetion calibrations in part two of this study. The latter effort entailed the determination and calculation of factors representing the fuel economy influence of ignition timing and carburetor calibration differences in certification test vehicles. Using the VEHSIM program with auxiliary programs VSIMI and VSIMII, specific calculations were made for distributor and carburetor calibration curves representing equipment in 1976 model year cars.
