Introduction to S4000 Flanged Gas Train SystemsTurbocharged Natural Gas® Dual Fuel Systems
BackgroundThe American Power Group (APG) Dual Fuel system is a patented aftermarket upgrade system which seamlessly meters natural gas into the induction system of a diesel engine.
S4000 Dual Fuel configuration does not change any of the OEM diesel engine components. APG’s Electronic Control Unit (ECU) monitors many base engine functions within the OEM engine system such as coolant temp, exhaust gas temp, load/manifold absolute pressure, etc., either through serial communication [the Controller Area Network (CAN) system (“read only”)] and/or through APG installed sensors.
The Dual Fuel controller will not allow natural gas to flow unless the base engine parameters are within normal operating range, therefore “cold” engine start‐up is on 100% diesel fuel. The conventional diesel engine governor controller acts to reduce diesel fuel flow as natural gas is introduced to maintain requested engine speed/load.
APG’s system is non‐invasive to the OEM diesel engine and takes a read only position to the OEM CanBus network. If for any reason, the engine parameters are not within standard operating range, as programmed in the APG ECM, the APG Mixed‐Fuel system turns off the NG flow and returns the engine back to 100% diesel fuel operation.
APG Gas TrainFrom the fuel source, the APG Dual Fuel system gas train is comprised of a gas filter, zero governor regulator, dual solenoid shut off valve, variable fuel metering valve and induction gas mixer upstream of the diesel engine turbocharger and intake manifold.
APG Control SystemAPG’s ECU monitors all engine parameters through the CAN access or installed sensors and operates the natural gas fuel control valve and variable fuel metering valve for seamless operation. Operational information is available through a Remote Display Unit (RDU).
Operational Fuel CostDepending on the natural gas fuel source, we expect an average range of 40% ‐ 55% displacement, with peak displacement up to 75%, allowing end users to see a significant reduction in fuel costs.
Detroit‐based powertrain engineers designed and tested APG’s patented 3rd generation Turbocharged Natural Gas® Dual Fuel Technology
