Abstract: A fuel delivery system for an engine is provided. The fuel delivery system includes a tank, a temperature sensor, a delivery conduit, a return conduit, a heat exchanger, a first valve, a second valve, an accumulator, and a controller. The controller is configured to receive a signal indicative of a temperature of a fuel present within the tank. The controller is also configured to control at least one of the first valve and the second valve to selectively bypass at least a portion of the fuel to the tank through the return conduit and the accumulator based, at least in part, on the received signal. The portion of the fuel is adapted to raise the temperature of the fuel present within the tank.

Abstract: A fuel level measurement system and method for liquified natural gas (LNG) powered machines is disclosed. An engine control module (ECM) receives fuel line pressure levels at a first time (e.g., a key-off event) and, again, at a second time (e.g., a key-on event). The ECM predicts an expected change in pressure from the key-off event to the key-on event based on various factors. If the change in pressure detected is greater than a threshold level different from the predicted change in pressure, the ECM determines a fill event and resets a current fuel level. The ECM tracks mass flow commands used to provide fuel to the engine to determine the consumption of fuel from the fuel tank and to determine a new current fuel level based on the amount of fuel consumed. The current fuel level is displayed on a fuel gauge.

Abstract: A dual fuel engine control system includes a pressure sensor, and an electronic control unit coupled with the pressure sensor and structured to receive cylinder pressure data indicative of cylinder over-pressurization, and to switch the system to a limited gas-to-liquid substitution mode based on the cylinder pressure data indicative of cylinder over-pressurization. The electronic control unit is further structured to return the system to a normal gas-to-liquid substitution mode, receive cylinder pressure data indicative of cylinder over-pressurization after returning the system to the normal gas-to-liquid substitution mode, and responsively output a gas substitution fault signal.

Abstract: A fuel delivery system for an engine is provided. The fuel delivery system includes a tank, a temperature sensor, a pressure sensor, a delivery conduit, a return conduit, a heat exchanger, a first valve, a second valve, and a controller. The controller is configured to receive a signal indicative of a temperature of a fuel present within the tank. The controller is also configured to receive a signal indicative of a pressure of the fuel downstream of the heat exchanger. The controller is further configured to control at least one of the first valve and the second valve to selectively bypass at least a portion of the fuel in a gaseous state to the tank through the return conduit based, at least in part, on the received signals. The portion of the fuel is adapted to raise the temperature of the fuel present within the tank.
