DETROIT ENGINES
DD13/DD15/DD16
The Detroit DD Series is a family of heavy-duty, inline-6 diesel engines used mainly in Freightliner and Western Star trucks.
- All three DD13/DD15/DD16 engines are inline 6-cylinder, turbocharged, electronically controlled diesel engines.
- Engine Displacement
- DD13 → 12.8 L
- DD15 → 14.8 L
- DD16 → 15.6 L
- Detroit lists the DD family as part of its heavy-duty engine line.
- A FASS System can:
- Help DD13/DD15/DD16 engines by improving fuel supply consistency, removing air/vapor from the fuel, improving filtration before the factory system.
- Protect the high-pressure fuel system from aeration or contamination-related wear.
- A FASS System Solves loss of prime issues caused by faulty OEM Filter housings.
- Makes secondary filter post maintenance priming unnecessary.
Series 60
The Detroit Diesel Series 60 is a heavy-duty, inline-6 diesel engine commonly used in Class 8 trucks, buses, fire apparatus, vocational equipment, and some industrial or marine applications.
- The Series 60 was produced in 11.1L, 12.7L, and 14.0L versions and is a 4-stroke, turbocharged, electronically controlled diesel engine using Detroit’s DDEC electronic control system.
- Engine Displacement
- 11.1 L
- 12.7 L
- 14.0 L
- It is best known for its highway truck use, especially the 12.7L Series 60, where fleets valued its durability, fuel economy, rebuildability, and strong electronic diagnostics.
- A FASS System can:
- Help Series 60 because its electronic unit injector system depends on steady, clean fuel delivery, and many older Series 60 trucks now deal with aging tanks, long fuel lines, suction leaks, fuel restriction, water contamination, or aeration that can contribute to hard starts, rough idle, injector wear, low power, and inconsistent fuel pressure.
- Makes secondary filter post maintenance priming unnecessary.
Series 71 & 92
The Detroit Diesel Series 71 and Series 92 are classic two-stroke diesel engine families used in trucks, buses, military equipment, marine vessels, generators, and industrial machinery.
- The Series 71 uses about 71 cubic inches per cylinder and came in inline and V configurations such as 4-71, 6-71, 6V71, and 8V71, while the Series 92 uses about 92 cubic inches per cylinder and was commonly built in V configurations such as 6V92, 8V92, 12V92, and 16V92.
- Engine Displacement for Detroit Series 71 (2‑stroke)
- 71 cubic inches per cylinder (≈ 1.2 L per cylinder)
- Total engine size depends on cylinder count:
- 6‑71 → ~7.0 L
- 8V‑71 → ~9.3 L
- 12V‑71 → ~14.0 L
- Engine Displacement for Detroit Series 92 (2‑stroke)
- 92 cubic inches per cylinder (≈ 1.51 L per cylinder)
- Total engine size examples:
- 6V92 → ~9.0 L
- 8V92 → ~12.1 L
- 12V92 → ~18.1 L
- 16V92 → ~24.1 L
- These engines are known for their distinctive Detroit two-stroke sound, Roots-blower scavenging system, mechanical unit injectors, strong rebuildability, and wide use in older vocational, bus, marine, military, and stationary equipment.
- A FASS System can:
- Help Series 71 and Series 92 engines because many of these older two-strokes are running with aged tanks, older fuel lines, mechanical unit injectors, and contamination-prone fuel systems, so improved fuel polishing, water separation, and steadier supply can help reduce injector wear, rack-related fueling inconsistencies, smoke, hard starts, and power loss caused by dirty or aerated fuel.
- Makes secondary filter post maintenance priming unnecessary.
DETROIT ENGINES
Detroit is a diesel engine and powertrain brand best known for heavy-duty truck engines used in Freightliner, Western Star, buses, fire apparatus, marine, military, generator, and industrial equipment. Detroit’s current highway engine family is the DD Series, while its best-known legacy engines include the Series 60 and the older two-stroke Detroit Diesel engines such as the Series 53, 71, 92, and 149.
Detroit engines are generally known for:
- High-mileage durability
- Strong parts availability
- Good electronic diagnostics, especially from DDEC-era engines onward
- Fuel economy and integrated powertrain design on modern DD engines
- Wide application range, from highway tractors to marine, military, industrial, bus, fire, generator, and vocational equipment
