American Power Group Inc. received online notification from the U.S. Environmental Protection Agency that its recent Clean Alternative Fuel Vehicle and Engine Conversion Submissions have been approved for the following Outside Useful Life 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 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 requirements. 

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