Abstract |
This report discusses the derivation of I/M benefits for the post-1980 Federal fleet as contained in EPA's emission factor model MOBILE2. As is widely recognized, the post-1980 model year fleet will be predominantly composed of vehicles which employ what has become known as three way catalyst technology. This technology incorporates a sophisticated microprocessor-based engine control system which holds the air/fuel ratio very close to stoichiometry, thereby allowing the three way catalyst to simultaneously convert hydrocarbons (HC), carbon monoxide (CO) and oxides of nitrogen (NOx) to harmless by-products. As could be expected, such a significant shift in technology will have an impact on the expected in-use emissions performance of these vehicles both with and without an inspection and maintenance (I/M) program. |
