Detroit Diesel Series 60 11.1L Engine Specifications & Applications

Overview of the Detroit Diesel Series 60 11.1L Engine

The Detroit Diesel Series 60 11.1L is the original displacement variant of the legendary Series 60 engine family. Introduced in the late 1980s, the 11.1L (or 677 cubic inches) version set the standard for electronically controlled heavy-duty diesel engines. Designed as an inline 6-cylinder, 4-stroke, turbocharged diesel, this engine became a staple in both on-highway and off-highway markets—including marine, industrial, and power generation sectors.

Unlike later 12.7L and 14L versions, the 11.1L was engineered for moderate-duty applications requiring fewer emissions controls and offering exceptional fuel economy, simplified serviceability, and robust mechanical durability. Its lower displacement and advanced electronics made it an ideal platform for marine auxiliary power, diesel-electric applications, irrigation pumps, and mid-size generator sets—especially when uptime, diagnostics, and affordability are priorities.

Key Features of the Series 60 11.1L Engine

The 11.1L Series 60 brought Detroit Diesel Electronic Control (DDEC) into the market, providing more accurate fueling, better diagnostics, and reduced fuel consumption without the complexity of today's aftertreatment systems. While later 12.7L and 14L versions targeted higher output, the 11.1L is prized for its simplicity, economy, and longevity.

Advantages:

Lower fuel consumption than mechanical engines of similar size
Ideal power-to-weight ratio for auxiliary systems and mid-size propulsion
Mechanical simplicity with electronic precision (DDEC I & II)
Full aftermarket support for remanufacturing and repair
Durable cast-iron block and cylinder head construction

Common Applications of the Detroit Series 60 11.1L Engine

Though the 11.1L Series 60 began its life in on-highway trucks, its robust design and adaptable configuration made it a popular repower and OEM option for many off-highway and marine platforms.

Marine Applications

Marine engineers and operators rely on the 11.1L engine for a balance of performance, serviceability, and fuel efficiency in a relatively compact package.
