Detroit Diesel Corp. 2013 Engine Enhancements

Detroit Diesel Corp. has made new enhancements to its engine family for 2013. Engineered to meet Greenhouse Gas 2014 regulations from the Environmental Protection Agency and the National Highway Traffic Safety Administration, the updated Detroit family of heavy-duty engines combines engine, electronics and BlueTec emissions technology improvements to benefit fuel economy. All Detroit heavy-duty engines feature the enhanced BlueTec emissions system. New components include a liquid-only DEF delivery system, which contributes to better fuel economy due to the elimination of air assist. A 1-Box package with fewer parts is now universally configured for all trucks, resulting in improved serviceability. Additional changes to every engine include enhanced DDEC engine electronics that contribute to improved engine control, optimized powertrain and BlueTec management, and accurate fuel reporting for the customer. Further contributing to ease of serviceability and decreased maintenance costs is the new fuel filter system. Ideal for regional, LTL and vocational applications, the updated Detroit DD13 engine features longer service intervals and improvements such as fuel injector nozzle modifications and a new crankcase sensor for OBD requirements. A variable-speed water pump creates greater efficiency compared to a gear-driven design. With ratings from 370-470 HP and a torque range from 1,250-1,650 pounds, the enhanced DD13 offers the power ratings customers demand. Detroit will continue to offer the DD15 TC with turbo compounding, which will receive many of the engine family changes including the new DDEC electronic controls and improved fuel filter system. The DD15 TC will be available in many of the Freightliner and Western Star trucks and will continue to deliver the reliability and performance customers have demanded since its introduction in 2008. Rounding out the Detroit engine family, the enhanced Detroit DD16 now has a wider selection of available horsepower and torque ratings that have been shifted from the DD15 engine. With up to 600 HP delivering up to 2,050 pounds of torque, the DD16 was designed to haul the heaviest of loads through the most difficult terrains.
