How does the retrofit system work?
o The gasoline tank is removed and storage cylinders are placed either in the trunk, underneath a vehicle and/or body load space. The number and type of cylinders varies between vehicles depending on the GGE needed and tank space available. CNG is pumped from the gas valve into the cylinders at the refueling station. As needed, CNG travels through the master manual shut-off valve and into the engine via high pressure fuel lines. The gas enters a regulator in the engine compartment, which reduces the pressure of the natural gas to approximately 100 psi depending upon engine system and certification. The gas from the regulator through a custom designed fuel rail to the newly installed gaseous fuel injectors. The gas mixes with air and flows through the induction system and finally enters the engine’s combustion chambers.
