CCAT has become the FIRST company to be
awarded a California Air Resource Board (CARB)
propane-diesel dual-fuel off-road Alternative
Fuel Certification. CARB issued Executive Order
B-56U on November 3, 2011.
CCAT’s DUAL FUEL RETROFIT SYSTEM (DFRS): works with existing Diesel Engines in combination with either Propane or Natural Gas.
A typical system consists of the following components: ECU, injector bank, fuel regulator, electronic fuel metering device, sensors, fittings and accessories. The various components of the system are installed externally to the engine and at no time is the engine disassembled or tampered with during the installation procedure.
The CCAT ultra-sophisticated dual-fuel system uniquely controls both the propane and diesel injection rates. The system injects propane into the air intake manifold on the pressure side of the turbocharger and after the intercooler. This system originally was developed as an OEM CNG system for small diesel pickup trucks. It has been adapted to work with propane on heavy-duty engine applications such as the Caterpillar 3406/C15 and Cummins QSM11.
CCAT has matched the best exhaust treatment system available to the DFRS to maximize the effect of this combination of technologies to achieve best available control technology (BACT) status.
PERC GRANT
CCAT would like to give a special thanks to the Propane Education and Research Council (PERC) for their grant that enabled CCAT to complete development of the DFRS and carry it through CARB Certification.
