The California Energy Commission (CEC) approved a $1 million grant to develop a 12-liter natural gas engine for heavy-duty vehicles that produces near-zero nitrogen oxide tailpipe emissions, the commission has announced.

The grant focuses on existing engine research and consists of engine development and on-road vehicle demonstration. The engine will be offered as an option for fleets with larger vehicles, according to CEC.

The South Coast Air Quality Management District will work with Cummins Westport, Inc., to develop the engine. The development of the natural gas engine will help meet the California Air Resources Board's (CARB) 2010 emissions standards and support efforts to improve air quality in the South Coast and San Joaquin Valley air basins.
