MaxxForce DT Engine
The DT has long been referred to in the industry as "The Legend." Bringing traditional big bore features, such wet-sleeve design, in-chassis rebuild possibilities, and premium design elements, to the mid-range diesel market is the big idea that gave rise to the legend. For many years, Class 6-7 truck buyers made this engine the market share leader due to its dependability and performance, which led to a low cost of ownership and great residual value. Diesel Power magazine clearly said as follows while listing the DT as one of the "Top 10 Diesel Engines - Ever": Put simply, these are the engines that fleet managers all over America prefer because they are dependable, effective, and good at moving freight. They have earned the respect of drivers and operators worldwide and can even be repaired inside the truck's chassis.

Career-Related Applications
To satisfy the needs of clients from throughout the world, the MaxxForce DT was developed. It is compatible with a wide variety of automated and manual driveline options, as well as thousands of different build configurations, to suit the broadest range of on- and off-highway applications. The MaxxForce DT has a power range of 215–300 hp and a torque range of 560–860 lb.-ft. with torque. using torque. Peak torque can be improved when shift energy management technology is used in conjunction with particular transmissions.
Outstanding Power
MaxxForce DT engines feature dual sequential turbochargers to deliver outstanding performance for any activity. While the larger secondary turbo produces maximum power at higher speeds and on inclination, the smaller primary turbo reacts quickly for an immediate launch at low engine speeds. The two successive twin turbochargers offer the following:
- Fewer moving parts and complexity for more dependable performance
- Wastegate prevents excessive bearing loads and overboost
- Great pulling power on steep climbs thanks to excellent throttle response with peak torque at 1,000 to 1,200 rpm.
Reliability
The DT's renowned dependability is based on a strong, time-tested foundation. The following provide evidence of the DT's dependability:
- Premium plateau-honed cylinder design
- The wet-sleeve design's precise machining
Durability
The precision-machined wet-sleeved structure of the MaxxForce DT provides heavy-duty engine durability. Six bolts per cylinder provide the head-gasket integrity that competitive four-bolt systems cannot. Further extending engine life are high-quality valvetrain components and a low-friction design. The potential of this engine to undergo a complete in-frame rebuild increases its appeal. Because of this, it is much less expensive to repair the engine to factory specifications than it would be to remanufacture it, providing them a sizable value advantage when they sell it.
Energy Curves
560 lb.-ft. / 215 HP
The inline 6-cylinder engine of the MaxxForce® DT provides significant power with ratings of up to 300 horsepower and 860 lb.-ft. using torque. The dual-sequential turbochargers are designed to deliver powerful performance in any situation. While the smaller, low pressure turbo reacts quickly for an immediate takeoff at low engine speeds, the larger, high pressure turbo offers peak power at higher speeds and on steep hills.
