The American Power Group dual fuel system is a US patented after-market conversion system which meters natural gas into the induction system of a diesel engine.
The dual fuel configuration does not change any of the original engine manufacturer (OEM) diesel engine components and monitors compliance with OEM system parameters like oil pressure, coolant temperature, exhaust gas temperature, manifold air pressure, diesel fuel pressure etc, either through the Communication Area Network (CAN) system or installed sensors.

The dual fuel controller will not allow gas to flow unless the base engine parameters are within standard operating range (i.e. the gas does not flow until the engine coolant temperature and exhaust gas temperatures are at "normal" operating values, therefore "cold" engine start-up is on 100% diesel fuel). The conventional diesel engine governor controller acts to reduce diesel fuel flow as gas is introduced to maintain requested engine speed/load.

The OEM diesel engine control system remains unchanged with the V5000HD dual fuel system. If for any reason the engine parameters are not within standard operating range or the gas storage pressure falls below 210 kPa, the dual fuel system turns off the gas and seamlessly returns the engine back to 100% diesel fuel operation. Also, if the gas fuel supply is depleted, the system automatically returns to 100% diesel fuel.
