This report discusses a proposal for new exhaust emission factor rates of hydrocarbons (HC) carbon monoxide (CO) and oxides of nitrogen (NOx). The new exhaust emission rates were developed for 1975-1980 light-duty gasoline vehicles at both high and low altitudes. The rates were not updated for the California region. The HC and CO rates were developed from a sample of vehicles that excluded those with evidence of air pump tampering, catalyst removal and misfueling. The NOx emission rates were developed from a sample that excluded the same vehicles plus those with evidence of EGR tampering. The HC and CO rates for 1980 are substantially lower than MOBILE2, while the HC, CO, and NOx rates for 1975-1979 are little changed from MOBILE2. Included in this report are the effect of these new rates.
