Dual Fuel Systems for Vehicular Diesel Engines

The Science Behind APG’s Dual Fuel Technology for Vehicular Applications

American Power Group’s Dual Fuel Technology is an EPA-approved, aftermarket upgrade system that seamlessly meters a secondary fuel into the induction system of diesel engines for over-the-road and return-to-base fleets. APG provides an affordable solution that reduces both costs and greenhouse gas emissions.

Our Dual Fuel Technology is a negative pressure system that uses the diesel engine’s governor to reduce diesel fuel usage, as the higher energy value of the secondary fuel mixed with air is recognized at the point of compression flash point. Remaining diesel fuel provides proper engine lubricity and helps retain the power and torque of the base engine.

Depending on the secondary fuel source, owners can expect an average range of 40–55% displacement, with potential peak displacement up to 75%. Fleet owners have seen fuel savings up to 40% and can achieve their environmental goals by choosing carbon-neutral or carbon-negative fuel sources.

• No loss of power and torque
• Fuel savings impact the bottom line
• Utilize domestic fuel sources
• CARB and EPA approved
• Meet environmental goals with carbon-neutral or carbon-negative fuel sources
• Return to base engine operations at any time – no range anxiety
