Detroit Diesel Series 50
From CPTDB Wiki
The Detroit Diesel Series 50 is an 8.5 litre, inline, four cylinder, diesel engine. Introduced in 1993, the Series 50 was built off of the existing block of the Detroit Diesel Series 60. The Series 50 engine was used as a major bus engine in the United States and Canada and was used for trucks, motor homes, and construction and industrial equipment.
The Series 50 engine was fully electronically controlled and used DDECIII and later DDECIV electronics. The overhead cam engine featured electronic unit injectors and was turbocharged and air-to-air intercooled. Being built off the Series 60, it shared the same cylinder kits, bearings, gear train, rocker arms, valves, and pumps.[1]
In response to the EPA 2004 emissions standards, Detroit Diesel announced in March 2000 revisions to the Series 50 for 2000. This included the addition of an exhaust gas recirculation (EGR) system and a variable geometry turbocharger (VGT). These components were controlled by the DDEC IV engine controls.[2] Though the EPA 2004 emissions standard didn't take affect until October 2002, the engine was made available before that time.[2] To further reduce particulate emissions to lower than 2007 levels of 0.01 g/bhp-hr, there is an option to use ultra low sulfur diesel and particulate filter.[3]
In September 2004, Detroit Diesel ceased production of the Series 50 for on highway applications.
