The MOBILE4 Tech IV Credit Model is used to estimate the emission factor equations, the effects of Inspection and Maintenance (I/M) programs, and the bag fraction equations for 1981 and later passenger cars. The model's results are then stored in the EPA MOBILE4 emission factor model database. The report describes the development, use and results of the Tech IV model. It also documents the normalized bag fractions, high altitude emission factors, biennial I/M credits, and idle emission I/M credits used in MOBILE4.
