Clean Air Act violations

In 1998, the EPA announced fines totaling $83.4 million against Detroit Diesel and six other diesel engine manufacturers, the largest fine to date, which evaded testing by shutting down emissions controls during highway driving while appearing to comply with lab testing. [17] The manufacturers also agreed to spend more than $1 billion to correct the problem. [18] The trucks used engine ECU software to engage pollution controls during the 20-minute lab tests to verify compliance with the Clean Air Act, but then disable the emissions controls during normal highway cruising, emitting up to three times the maximum allowed NOx pollution. [18]

In 2016, Detroit Diesel agreed to pay US$28.5 million to resolve violations of the US federal Clean Air Act. The company sold 7,786 heavy-duty diesel engines, which were assembled approximately 80% complete in 2009, including the crankshaft, block, pistons, and connecting rods, the short block engines were stored temporarily and completed the remaining assembly in early 2010 for use in trucks and buses of in model year 2010. [7] These engines were alleged not to comply with stricter 2010 emission standards. [7]

It was most active in association with GM's Detroit Diesel Engine Division, which produced lines of lightweight diesel engines that could be adapted to many uses including road vehicles, small boats, military equipment, construction and farm equipment, pumping, and auxiliary power generation. In 1939, Detroit Diesel Series 71 engines were installed in buses produced by Yellow Coach, who would be acquired by GM in 1943 to launch the GMC Truck and Coach Division. Uses for Detroit Diesel engines would proliferate during World War II and the postwar economic boom. The GM Cleveland Diesel Engine Division's products were sold to relatively few customers for mostly marine uses.
