Greenkraft, a California-based manufacturer of alternative fuel systems and trucks, announced that its 8L V8 CNG-powered engine received new certification from the California Air Resources Board’s (CARB) “On-Road New Vehicle and Engine Certification Program.”
Greenkraft says its 8L V8 fuel-injected engine achieved a NOx emission value less than 0.02 g/bhp-hr, which meets the optional near-zero NOx level set by CARB. This engine is available as either a stand-alone product or can be installed in one of Greenkraft’s 26,000 GVW or 33,000 GVW heavy-duty trucks.
To be certified, a vehicle must demonstrate that its exhaust and evaporative emission controls systems are durable and comply with the emission standards for the vehicle’s useful life. CARB reviews a production vehicle’s durability and compliance with emissions requirements, on-board diagnostics, anti-tampering, fuel tank fill-pipe and openings, crankcase emissions, among other things.
