The Detroit Diesel Series 50G was an 8.5 litre, inline, 4-cylinder natural gas engine. Introduced in September 1993, the Series 50G was derived from the diesel-fueled Series 50. Both engines were popular for transit bus applications in the United States and Canada. The four stroke, overhead cam engine used a lean burn combustion process. It featured a wastegated turbocharger and air-to-air charge cooling. Production of the Series 50G engine ended in 2005.
The Series 50G engine was fully electronically controlled and used DDECIII and later DDECIV electronics.
