EPA's engine research focuses on developing engines that are simultaneously clean, efficient, and cost effective, and which have high potential to produce real-world benefits.
Clean Diesel burning technology is one example of these innovative engine concepts. EPA's testing suggests the potential for a diesel engine design, using innovative air, fuel, and combustion management and conventional particulate matter aftertreatment, to achieve lower NOx levels without the need for NOx after treatment. EPA is developing this technology as a potential alternative with other diesel emissions control approaches (e.g., NOx adsorbers, urea selective catalytic reduction (SCR), etc.).
Clean Diesel burning technology shows the potential to meet NOx levels "engine-out" over the entire engine operating range, to a level required for future diesel emissions standards. EPA has partnered with several automotive and engine manufacturers to evaluate the production feasibility of this technology. Using clean diesel combustion technology in conjunction with the full hydraulic drive is projected to improve fuel economy more than using either technology alone.
