Abstract The Environmental Protection Agency was mandated by the 1977 Clean Air Act Amendments to determine the statutory NOx emission standard for 1985 heavy-duty engines. The standard was to be based on a 75 percent reduction from the average measured emissions for uncontrolled (1972-73 model year) gasoline-fueled heavy-duty engines. To establish the amount of NOx emissions from the uncontrolled heavy-duty gasoline-fueled engines, ECTD began a baseline testing program. This program consisted of four sections: (1) engine procurement, (2) restorative maintenance, (3) testing the engine emission levels using the transient test procedure, and (4) determination of the average measured emissions. Twenty-six engines were tested with 73 valid tests to obtain the average NOx emissions. Based on the results of these emission tests, the average NOx emission level is 6.8 g/BHP-hr. The CAAA of 1977 calls for a 75 percent reduction in NOx emissions as the statutory emission standard; complying with this requirement the 75 percent reduction prescribed yields a heavy-duty engine NOx emission standard of 1.7 g/BHP-hr.
