The California Energy Commission has awarded the Gas Technology Institute a $1 million grant to develop and demonstrate an advanced natural gas engine to be installed in 18 vehicles, such as delivery trucks and school buses.
The Cummins-Westport Inc. ISB6.7 G natural gas engine meets the 2018 U.S. Environmental Protection Agency (EPA) Heavy-Duty Onboard Diagnostics (HD-OBD) requirements, as well as the California Air Resources Board’s (CARB) optional low NOx emissions.
Both CARB and the EPA are requiring all heavy-duty alternative fuel vehicles to run onboard diagnostics (OBD) beginning with the 2018 model year. Since 2013, all heavy-duty diesel vehicles have required OBD, but the OBD requirement for alternative fuel vehicles was pushed back until 2018.
