Ten in-use 1985 Mercedes-Benz light-duty diesel vehicles equiped with particulate trap oxidizer systems and with mileages between 30,000 and 50,000 miles were tested for particulate (PM) and gaseous exhaust (HC,CO, CO2, and NOx) emissions. Seven out of ten vehicles had a first-test particulate emission level lower than a predetermined cutoff point of 0.35 g/mi. (The California PM certification standard for 1985 light-duty diesel vehicles is 0.4 g/mi.) Attempts were made to regenerate the particulate trap oxidizers on the three vehicles which exceeded the 0.35 g/mi PM level and the vehicles were retested. Two of three retested vehicles passed the PM cutoff level.
