Detroit Diesel Injectors

Equipment Intelligence

The Detroit Diesel 2-Stroke Engines are an efficient and compact engine used for main propulsion and stationary applications. Debuting in 1939, Detroit Diesel Corporation (DDC), created by General Motors (GM), introduced the Series 53 Engine and Series 71 Engine. With the 53 Series two-stroke diesel engines "Detroits" found their way into automotive, marine, standby power generation and military applications. By 1925 DDC had manufactured over 1 million units.

In the 1980s, the US Government's Environmental Protection Agency (EPA) began introduction of laws resticting emissions which directly affected DDC 2-Stroke Engines as well as others. Production ended of these workhorse engines as they were deemed old technology and not economically viable for upgrade to these new requirements, sidelined in favor of more environmentally friendly four-cycle engines. The exception to the environmental rules was for engines used in National Security such as Military Equipment. In 2006, MTU purchased the rights to off-road applications of the 2-stroke engines from DDC and continued to support these engines through their lifecycle.

Around the world, many of these "Detroits" were, and in many cases still are, in service in hard-working city buses, generators, pumps, haul trucks, aircraft ground support equipment, commercial marine vessels, high-end marine pleasure craft and most of the world's armies, air forces and navies. As of 2023, more than 250,000 2-stroke diesel engines remain in service globally.
