The traditional way to control motor vehicle emissions, towards the ultimate goal of achieving a desired level of air quality, has been the command and control approach. That is, the US Congress or Environmental Protection Agency (EPA) set a level of emissions that may not be exceeded by a vehicle for a defined useful life, when measured according to a predetermined and highly specific protocol. Such is the case at present for diesel-fueled heavy-duty engines, which must meet exhaust emission standards for hydrocarbons, carbon monoxide, oxides of nitrogen and particulate matter of 1.3, 15.5, 10.7 and 0.60 grams per brake horsepower-hour (g/bhp-h), respectively. Beginning in 1991, the tailpipe emission standard for nitrogen oxides will be tightened further to 5.0 g/bhp-h and the standard for particulate will be lowered to 0.25 g/bhp-h for trucks and 0.10 g/bhp-h for urban bus engines. For 1994, all heavy-duty diesel engines will be required to meet the 0.10 g/bhp-h particulate standard - and the authors will usher in the age of the smokeless diesel, provided the technology to achieve this extremely demanding combination of exhaust emission standards can keep pace with the regulatory demands. Correspondingly stringent standards are in place for gasoline-fueled heavy-duty engines.
