The Detroit Diesel Series 50 is an

Series 60, which itself was initially designed by Detroit Diesel. The cylinder heads were cast by John Deere

at one time.

History

The Series 50 engine is used as a major

inline six, V-6 or V-8

diesel engines.

In 2000, in order to better respond to more stringent EPA emissions standards, Detroit Diesel announced revisions of the Series 50 for diesel applications. The changes included the addition of an exhaust gas recirculation (EGR) system, and a variable geometry turbocharger system to improve torque.

In September 2004, Detroit Diesel ceased production of the Series 50 heavy duty diesel engine for on highway applications due to emissions standards. It is still available for off-road applications. A replacement was scheduled to take place in 2007, then was pushed back until 2009. According to Detroit Diesel, Series 50 engines will no longer be produced for non-

Daimler AG

trucks or buses beginning in 2010.

Alternative fuels

In addition to being powered by diesel fuel, the engine can also use alternative fuels such as

liquified natural gas (LNG) under the Series 50G label. Several thousand Series 50 propelled buses are now on the streets of major cities such as New York City and Los Angeles

.
