The project received funds from the Energy Commission’s Clean Transportation Program and Natural Gas Research and Development program.

The engine is a critical technological advancement, offering an immediate commercially available technology to help achieve the state’s sustainable freight, clean air, and climate goals. This was the first midrange engine in North America to receive emission certifications from the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) that meet the 0.02 grams per brake horsepower-hour optional Near Zero NOx Emissions standards for medium heavy-duty truck, urban bus, school bus, and refuse applications.

The engine has already exceeded the 2016 U.S. Department of Transportation/EPA standards for greenhouse gas emissions. It is on track to exceed proposed future standards. While the engine has been heavily modified to reduce related greenhouse gas emissions, the performance is comparable to the diesel-powered counterpart.
