Detroit Diesel DD15™ Engine

Detroit Diesel Corporation recently showcased its new Detroit Diesel DD15™ engine to legislators and government agencies at the SAE International Government Industry meeting. The DD15 was featured because it exemplifies goals of the Department of Energy’s 21st Century Truck Partnership focusing on new ways to move freight while reducing pollution and dependency on foreign oil.

“We applaud the spirit of innovation at Detroit Diesel and recognize the company for its contribution to creating a new generation of engine technology that meets current and future emission regulations while meeting our shared and immediate goals for significant reduction in fuel consumption,” said Alexander Karsner, DOE assistant secretary for Energy Efficiency and Renewable Energy. “It is rewarding to see real examples of outcomes of these projects, such as these we see today, being incorporated in the brand new DD15 engines from Detroit Diesel. These innovations offer long-reaching and positive implications for surface transportation fuel use in this country.”


The Office of Energy Efficiency and Renewable Energy, through the Office of Vehicle Technologies, has partnered with several diesel engine manufacturers to develop advanced technologies in the areas of combustion, emission control and system integration. The result of the largest investment ever made in the development of an engine by an engine manufacturer, the DD15 achieves its goals through the application of a new Amplified Common Rail System (ACRS), as well as innovative turbo compounding technology.

Production of the DD15 began in March. Built with the upcoming EPA 2010 standards in mind, the DD15 is an EPA ‘07 engine that relies on a specialized after-treatment device to prevent the emission of harmful particulates into the atmosphere.

Detroit Deisel, in collaboration with the DOE, developed key methodologies for controlling the physical and chemical processes that occur during particulate aftertreatment soot capture and regeneration. “We applaud the spirit of innovation at Detroit Diesel and recognize the company for its contribution to creating a new generation of engine technology that meets current and future emission regulations while meeting our shared and immediate goals for significant reduction in fuel consumption,” Karsner said.

“Fuel economy is the single-most important development target for our engines. We are looking forward to our continued collaboration with the DOE in developing and bringing to market new technologies that help meet the national goal of reduced petroleum consumption,” said Bernard Heil, head of Daimler Trucks’ Engine Development. The DD15 is the first in a family of new worldwide heavy-duty engines from Daimler Trucks being jointly developed by engineering teams in Germany, Japan and the U.S.

“We are proud to have collaborated with the DOE on technology development programs because we fully recognize the value of this partnership to the technical advancements incorporated into our new products.” “It is rewarding to see real examples of outcomes of these projects, such as these we see today, being incorporated in the brand new DD15 engines from Detroit Diesel,” Karsner said. “These innovations offer long-reaching and positive implications for surface transportation fuel use in this country.”

ABOUT THE DD15

Detroit Diesel DD15™ engine.

The DD15’s after-treatment system uses advanced technology to capture soot through a particulate filter. Temperature control across all system components also plays a major role in the after-treatment system and ultimately overall engine efficiency. Innovation leading to development of the DD15 also led the company to announce a series of enhancements to the diesel particulate filter regeneration process for the EPA ‘07 version of Detroit Diesel’s venerable Series 60® engine.

These enhancements will deliver up to a 2.5 percent reduction in fuel consumption by the EPA ’07 Series 60 engines already on the road. In addition, development of the DD15 led to other areas of engine technology advancements including: Detroit Diesel’s new ACRS, Turbo Compound System and integrated Jacobs Brake.
