APG’s dual fuel system converts diesel engines and diesel generators to function more efficiently and at a lower operating cost by seamlessly displacing 40%-70% of the normal diesel fuel consumption with CNG, LNG or bio-methane.

APG said that its system is non-invasive to the OEM engine and operates within all OEM performance controls with the flexibility to return to 100% diesel operation at any time.

The EPA test exemptions will allow APG to gather critical engine performance and emission data on a pre-dual fuel and post-dual fuel basis to support EPA approval requirements and commence commercialization of their non-invasive dual fuel upgrade system in the US.

The initial vehicle to be tested for Casella Waste Systems will be a 2003 DT530 8.6 liter/275HP International refuse truck.
