The DD13 engine has been significantly redesigned with innovative new features, building on the legacy of the most popular Class 8 diesel engines in North America.
The DD13 engine builds upon proven Detroit® technology to offer industry-leading power and productivity in this 6-cylinder engine.
Versatility for a wide range of applications.
New power ratings, greater application coverage, and available front and rear engine power take offs (FEPTO / REPTO).
Greater reliability than ever before.
Engineered to offer less complexity and more durability in many of its key components, the DD13 achieves an even higher standard of reliability.
Longer maintenance intervals.
The new Detroit® Aftertreatment System does more with less. This new ATS features a single, larger Diesel Particulate Filter (DPF) with Asymmetric Cell Technology for increased service intervals and 60-pound weight savings in a smaller housing. The new ATS works hand in hand with the Detroit heavy-duty platform of engines through techniques such as Asymmetric Injection and Auto-Elevate to ensure optimal temperatures, leading to fewer regens. When paired with the Detroit Vocational or On-Highway Series of DT12® transmissions, the engine can also ThermoCoast, keeping temperatures up during low load driving.
Better combustion for better fuel economy.
Ultra-high compression ratios combined with a new swirl piston design and a new, 10-pin injector create better combustion, reduce ash production, and improve fuel economy by up to 4% compared to previous models.
Detroit’s trusted service and technology.
Detroit’s #1 service network, along with the Detroit Connect Virtual Technician® remote diagnostic system, helps maximize uptime.
Enough power to get payloads moving quickly.
A simple, ball bearing, fixed Geometry Turbo allows peak power and torque to be reached faster, which gets payloads moving without compromising efficiency.
Longer maintenance intervals.
Better combustion for better fuel economy.
Versatility to be used in a wide range of applications.
Greater reliability than ever before.
