Detroit Diesel has a long history in marine, industrial, military, commercial-vehicle, and power-generation applications.

General Motors founded the GM Diesel Division in 1938. The Series 71 became the foundation of the company’s two-cycle engine range, followed by the Series 53, Series 149, and Series 92. Detroit Diesel introduced the four-stroke Series 60 in 1987, one of the first production heavy-duty diesel engines supplied with integrated electronic control as standard.

Important Detroit Diesel marine engine families include:

• Detroit Diesel Series 53
• Detroit Diesel Series 71
• Detroit Diesel Series 92
• Detroit Diesel Series 149
• Detroit Diesel Series 60
• Detroit Diesel 8.2L
• Detroit Diesel marine generator engines
• GM Diesel marine engines
• Gray Marine Detroit Diesel packages
• MTU Detroit Diesel engines
• Detroit Diesel–MTU Series 2000 and 4000 platforms

The modern Detroit brand primarily promotes engines and powertrain products for commercial road vehicles. Legacy Detroit Diesel marine and off-highway products are generally associated with Rolls-Royce Power Systems’ MTU service network and specialist Detroit Diesel distributors.

Detroit Diesel is particularly famous for its two-stroke diesel engines.

Unlike a conventional four-stroke engine, a Detroit Diesel two-cycle engine completes its combustion cycle with every crankshaft revolution. These engines use a mechanically driven blower to supply scavenging air to the cylinders.

Common Detroit Diesel two-stroke marine families include:

• Series 53
• Series 71
• Series 92
• Series 149

Typical marine applications include:

• Commercial fishing vessels
• Tugboats
• Workboats
• Passenger boats
• Patrol vessels
• Fireboats
• Landing craft
• Military vessels
• Marine generator sets
• Fire pumps
• Deck machinery
• Hydraulic power systems

Detroit Diesel two-stroke engines remain popular because of their:

• Compact installation dimensions
• High power-to-weight ratio
• Mechanical simplicity
• Strong parts familiarity
• Wide historical use
• Rebuildable cylinder-liner design
• Large international service base

Correct identification is essential because engines with the same basic family name may use different injectors, pistons, liners, blowers, turbochargers, governors, exhaust arrangements, and cooling components.

Detroit Diesel model designations commonly identify the number of cylinders and the engine family.

Examples include:

• Detroit Diesel 3-53
• Detroit Diesel 4-53
• Detroit Diesel 6V53
• Detroit Diesel 6-71
• Detroit Diesel 8V71
• Detroit Diesel 12V71
• Detroit Diesel 6V92
• Detroit Diesel 8V92
• Detroit Diesel 16V92
• Detroit Diesel 12V149
• Detroit Diesel 16V149
• Detroit Diesel Series 60

The designation can normally be interpreted as follows:

• 3, 4 or 6 before a hyphen – inline cylinder configuration
• 6V, 8V, 12V or 16V – number of cylinders in a V configuration
• 53, 71, 92 or 149 – approximate displacement per cylinder in cubic inches
• T – turbocharged on many specifications
• TA – turbocharged and aftercooled on many marine specifications
• N – naturally aspirated on selected engine descriptions

Examples:

• 6-71 – inline six-cylinder Series 71
• 8V71 – V8 Series 71
• 6V92TA – V6 Series 92, turbocharged and aftercooled
• 16V149 – V16 Series 149

Additional engine information may be contained in:

• Complete model number
• Engine serial number
• Arrangement or specification number
• Injector type
• Marine-conversion information
• Left-hand or right-hand rotation
• Heat-exchanger or keel-cooling arrangement
• Turbocharger model
• Governor or DDEC version

Before ordering, customers should provide the complete engine model, serial number, existing part number, component photographs, and vessel application.
