  • Compressed natural gas fuel mass control system
    Patent number: 9091240
    Abstract: A system, related method and computer program product are disclosed for controlling fuel mass of CNG received by an engine. The system may comprise a heat exchanger configured to receive CLNG and supply coolant and to output CNG and return coolant, an injector configured to inject CNG into the engine, a gas line between the injector and heat exchanger, a control valve configured to receive return coolant from the heat exchanger and to change the amount of return coolant flowing through control valve, and a controller connected to the control valve. The gas line may be configured to carry CNG from the heat exchanger to the injector. The controller may be configured to maintain a Gas Line Temperature within an operating range by adjusting the amount of return coolant flowing through the control valve based, at least in part, on the Gas Line Temperature and a Target Return Coolant Temperature.
