APG Gains EPA Approval for 85 More OUL Engines

January 2014, Vol. 241 No. 1

American Power Group (APG) received notification from the EPA that its clean alternative fuel vehicle and engine conversion submissions have been approved for use in two outside useful life (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 used APG’s V5000 Dual Fuel Turbocharged Natural Gas™ technology, which must meet the specific design, componentry and emission compliance criteria of 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 performs tests with an engine dynamometer for the more stringent intermediate useful life (IUL) requirements. An EPA engine family approval allows APG to market the specific engine model conversion without further emissions testing.

“This round of EPA approvals marks the completion of a majority of our Class 8 truck OUL emissions testing,” said APG CEO Lyle Jensen.

In the next few months, APG expects to complete its submission for one remaining targeted OUL engine family and seek approval of several additional engine models for the glider kit market.
