FUEL DELIVERY SYSTEM

摘要

A fuel delivery system for an engine is provided. The fuel delivery system includes a tank, a temperature sensor, a delivery conduit, a heat exchanger, a control valve, a check valve, a bypass conduit, a bypass 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 control the control valve to selectively reverse at least a portion of the fuel in a gaseous state from the heat exchanger to the tank through the bypass conduit 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.

1. A fuel delivery system for an engine, the fuel delivery system comprising:
a tank adapted to store a fuel; a temperature sensor provided in association with the tank, the temperature sensor configured to generate a signal indicative of a temperature of the fuel present within the tank; a delivery conduit coupled to the tank and the engine; a heat exchanger coupled to the delivery conduit downstream of the tank, the heat exchanger adapted to convert the fuel from a liquid state to a gaseous state; a control valve coupled to the delivery conduit downstream of the heat exchanger, the control valve adapted to control a flow of the fuel from the heat exchanger to the engine; a check valve coupled to the delivery conduit downstream of the tank and upstream of the heat exchanger; a bypass conduit coupled to the delivery conduit and parallel to the check valve; a bypass valve coupled to the bypass conduit; and a controller coupled to the temperature sensor and the control valve, the controller configured to:
receive the signal indicative of the temperature of the fuel present within the tank; andcontrol the control valve to selectively reverse at least a portion of the fuel in the gaseous state from the heat exchanger to the tank through the bypass conduit based, at least in part, on the received signal, wherein the portion of the fuel is adapted to raise the temperature of the fuel present within the tank.
