APG's technology converts existing diesel engines into more efficient and environmentally friendly engines that have the flexibility to operate on:

• Diesel and Compressed Natural Gas (CNG)

• Diesel and Liquefied Natural Gas (LNG)

• Diesel and various sources of pipeline and wellhead natural gas


Users experience significant fuel savings with no loss of power and torque, normal maintenance cycles with high up-time, ability to transfer systems to other eligible engines at end-of-life, and the freedom to hedge against future fuel risks by returning to a diesel-only operation if required.


APG’s Turbocharged Natural Gas® Dual Fuel System for stationary and vehicular engines has met specific anti-tampering design, componentry, and emission compliance criteria and guidelines as set forth by the EPA, including the new EPA Clean Alternative Fuel Vehicle Conversion regulations.
