摘要： A system, method, and apparatus for controlling intake manifold air temperature (IMAT) of a dual fuel engine are provided. A determination regarding whether IMAT is to be modified is performed, followed by modifying the IMAT by changing flow of coolant in a cooling circuit in fluid communication with a separate circuit aftercooler (SCAC) of a SCAC circuit from a first flow path to a second flow path when it is determined that the IMAT is to be modified. A portion of the first flow path overlaps a portion of the second flow path.

摘要： A liquefied gas fuel supplying apparatus includes an injector that injects fuel to an engine, a fuel tank that stores the fuel, a fuel pump that pumps the fuel from the fuel tank to the injector, a fuel cooler that cools the fuel that is pumped from the fuel pump to the injector, a fuel temperature sensor that detects a fuel temperature in a pipe, and an ECU. The ECU, during engine operation, estimates the fuel temperature in the pipe after engine stop, based on a detection value detected by the fuel temperature sensor, and performs drive control of the fuel cooler to cool the fuel, when the estimated temperature is higher than a temperature that is evaluated from a predetermined saturated vapor pressure curve.

摘要： The present invention provides a heat exchange system for a closed loop fuel delivery system. The heat exchange system generally includes a first pump, a heat exchanger, a high pressure pump pressurizes fuel. The heat exchanger, which is located downstream of the first pump, receives the pressurized fuel flow. The high pressure pump, which is located downstream of the heat exchanger, delivers a predetermined amount of fuel flow to a jet engine. The circulating pump receives fuel flow downstream of the heat exchanger and recirculates the fuel flow upstream of the heat exchanger.

摘要： A fuel conditioning and measuring system for testing diesel engines is disclosed. The system includes a fuel conditioning loop having first and second heat exchangers, one employing a heating medium, and one employing a cooling medium. The flow of the heating and cooling mediums to the heat exchangers is controlled by control valves which receive a signal indicative of the temperature of the fuel flowing through the system and compare the measured temperature to a desired temperature to generate a control signal for positioning the control valves appropriately. The system includes a mixing tank which serves as a buffer between the fuel supply and the test engine to ensure any disturbances from fuel returning from the test engine do not adversely affect the testing of the engine, and to provide a mechanism by which the temperature of the fuel can be more accurately controlled. Both a flow meter and a density meter are employed to measure the flow of fuel through the system to provide accurate indications of mass and volumetric flow.
