The Detroit Diesel Series 60 is a four-stroke diesel engine in 11.1L and 14.0L displacements, producing 275-600kW in generator set configuration. It features DDEC (Detroit Diesel Electronic Control) for precision fuel injection, real-time diagnostics, and J1939 data link compatibility. It is one of the most widely deployed mid-range diesel generator engines in North American history.

DDEC stands for Detroit Diesel Electronic Control — the proprietary engine management system on Series 60 and other modern Detroit Diesel engines. DDEC monitors engine parameters in real time, controls fuel injection timing and quantity for optimal efficiency and emissions, stores fault codes, and provides J1939 data link output for integration with building automation and generator monitoring systems.

Detroit Diesel and MTU are both brands within the Rolls-Royce Power Systems group (formerly DaimlerChrysler). Detroit Diesel refers to engines manufactured in Detroit under the Detroit brand identity. MTU refers to the German-engineered Series 2000 and 4000 engines from Friedrichshafen. While they share corporate ownership, they are distinct engine families with different designs and target applications.

Yes. The Series 60 is one of the most proven diesel engines in North American history, with millions of units deployed in heavy trucks, industrial equipment, and generator sets. Known for robustness, straightforward service, and universal parts availability. The DDEC electronic control system adds diagnostic capability that simplifies troubleshooting and reduces downtime.

The Series 71 and 92 are two-stroke diesel engines from Detroit Diesel's legacy lineup (1940s-1980s) — still in service in legacy standby and marine applications, cost-effective for non-Tier-4 applications. The Series 60 is a modern four-stroke engine (1987-present) with DDEC electronic fuel injection, better emissions performance, and longer service intervals. For new purchases, Series 60 is preferred.

The Detroit Diesel Series 60 in generator set application is primarily a Tier 2/3 engine. For Tier 4 Final applications, MTU Series 2000/4000 engines (successor technology from the same corporate family) should be specified. Power Generation Enterprises can advise on Tier 4 options — contact us at (818) 484-8550.

Series 60 parts are available through MTU/Detroit authorized dealers, Freightliner dealers (the Series 60 powers many Freightliner trucks), NAPA, and major aftermarket diesel parts suppliers. The universal availability of Series 60 parts — available at virtually any diesel shop in North America — is one of its key long-term ownership advantages.

Detroit Diesel generators are well-suited for commercial standby power, prime power in locations with strong Series 60 service infrastructure, and legacy replacement applications. The universal parts network makes Detroit ideal for facilities in areas with limited major-brand dealer support. Also popular for export to markets where Series 60 service knowledge is widespread.
