This paper describes the results of an exhaust emission testing program conducted for EPA by Automotive Testing laboratories. Twenty diesel-powered light-duty trucks were tested. Gross vehicle weight ratings for these trucks ranged from 5300 to 6200 lbs. The primary purpose of this program was to provide data to establish emission factors for light duty diesel-powered trucks. Secondary objectives included an assessment of the emission durability of the engines and an evaluation of fuel economy. The test vehicles were randomly selected from the general public in the St. Louis area using direct appeals to individual owners and referrals from other test participants. The test sequence included the Federal Test Procedure, the Highway Fuel Economy Test and several short tests. Mass emissions were also measured during individual steady state and transient modes of operation. The work was conducted during March and April of 1980. The average emission test results were very low and similar to those from diesel engines in passenger cars. It appears that diesel engines in light duty truck service demonstrate virtually no emission deterioration while in-use over their 'useful life' although two engines required major engine rebuilding before 50,000 miles.
