Specification
The Detroit DD15 engine is a premium 14.8-liter heavy-duty diesel engine, designed to deliver exceptional power and performance. Featuring a durable cast-iron block, advanced swirled piston technology and ball-bearing turbocharger to recover wasted exhaust energy. Producing up to 505 horsepower and 1850 lb-ft of torque, this inline 6-cylinder engine offers strong low-end pulling power ideal for long-haul transportation and heavy freight operations.
Coming along with its advanced fuel system, reduced maintenance requirements, and proven durability, the Detroit DD15 engine offers its long torque curve maintains strong pulling power at low RPMs around 1,100 RPM minimizing gear shifts on steep grades. To comply with modern environmental standards, the DD15 incorporates advanced emissions technologies such as Exhaust Gas Recirculation (EGR) and Selective Catalytic Reduction (SCR).
Variants
DD15 Gen 5
The Detroit Diesel DD15 Gen 5 builds on the platform with a ball-bearing, simple-geometry turbocharger, ultra-high compression, and an optimized swirl piston design. These upgrades focus on improving combustion efficiency, reducing parasitic losses, and maximizing fuel economy during sustained highway cruising.
DD15 Gen 6
The upcoming DD15 Gen 6 is being developed to meet stringent 2027 ultra-low NOx emissions standards. It is expected to introduce further refinements in combustion control and after treatment systems, along with updated efficiency-focused power ratings aimed at balancing performance with significantly reduced emissions.
DD15 TC (Turbo Compound)
The DD15 TC (Turbo Compound) variant enhances efficiency by capturing otherwise wasted exhaust energy and converting it into usable mechanical power at the flywheel. This system improves overall fuel efficiency and torque delivery without increasing fuel consumption, making it especially effective for heavy-duty long-haul applications.
