The CPB, together with existing Chart LNG vehicle fuel systems, will work safely and reliably and with minimized chance of venting during both vehicle operation and refueling. This feature enables simplified fuel station design and reliable SI engine operation independent of LNG fuel station capability.
Moreover, it will operate just as it does now when it receives saturated LNG (typically above 100 psi) from a fuel station. If it receives lower pressure (and saturation temperature) cold fuel from the fuel station, the CPB automatically raises the pressure (and temperature) of the vehicle fuel tank to reliably meet the engine’s pressure requirements. It also minimizes emissions and reduces the higher cost associated with alternative LNG fuel systems requiring cold fuel.
