APG Receives EPA Approval for Additional OUL Engines


American Power Group Inc. (APG) reports that the U.S. Environmental Protection Agency (EPA) has approved the company's recent clean alternative fuel vehicle and engine conversion submissions for a range of additional outside useful life (OUL) engines.

The EPA approvals are for the following OUL engines:

– Detroit Diesel: Series 60; 11.1L to 14L; (2002-1987)

– Volvo/Mack: D11, D12, D13, D16, E7, MP7, MP8, MP10; 10.8L to 16.1L; (2009-2002)

The submissions utilized APG's V5000 Dual Fuel Turbocharged Natural Gas technology, which APG says is required to meet specific design, componentry and emission compliance criteria per the EPA Final Rule 40CFR Parts 85 and 86.

Depending on the age and mileage of the targeted engine year to be converted, APG performs either an on-road emissions test to meet the OUL requirements or tests on an engine dynamometer for the more difficult intermediate useful life (IUL) requirements. APG says an EPA engine family approval allows the company to commercialize that specific engine model conversion in the market without further emissions testing.

‘APG is putting the foundation in place to facilitate a broad-base adoption of natural gas conversions for the North American Class 8 trucking industry,” says Lyle Jensen, CEO of American Power Group Corp. “With current OUL and future IUL approvals for CAT, Cummins, Detroit Diesel, Mack, Mercedes Benz, and Volvo engines, and an estimated 3 million plus Class 8 engines on the road today, APG is in a unique position to address a multibillion-dollar market through our WheelTime Authorized Dealer and Certified Installer Network.’
