American Power Group Corp. (APG) has received notification from the U.S. Environmental Protection Agency (EPA) that its recent clean alternative fuel vehicle and engine conversion submissions have been approved for additional engines, including Detroit Diesel Series 60 (11.1L to 14L, 1987 through 2002 model years) engines.

APG’s V5000 dual fuel turbocharged natural gas technology is also available for Volvo/Mack D11, D12, D13, D16, E7, MP7, MP8, MP10 engines of 10.8L to 16.1L for model years 2002-2009.

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, the company said. An EPA engine family approval allows APG to commercialize that specific engine model conversion in the market without further emissions testing.

“This round of EPA approvals marks the completion of a majority of our Class 8 truck OUL emissions testing. We now offer fleet operators the broadest range of OUL Class 8 engine model conversions than anyone in the industry,” said Lyle Jensen, CEO. “These specific approvals open up the APG Detroit Diesel dual fuel glider kit market as previously announced on August 6th and the Volvo-Mack engine families which are popular in the grocery and beverage distribution channels. Over the next few months, we expect to  complete our submission for the one remaining targeted OUL engine family and seek approval of several additional engine models for the glider kit market.”
