Abstract
A fuel system for a vehicle includes a fuel tank configured to provide fuel to an engine of the vehicle, a shutoff valve configured to selectively restrict a flow of the fuel along a flow path between the fuel tank and the engine, a temperature sensor configured to monitor a temperature of at least one of the engine of the vehicle or a temperature associated with a body area of the vehicle and provide a temperature signal, and a controller coupled to the temperature sensor and the shutoff valve. The controller is configured to control the shutoff valve to restrict the flow of the fuel in response to the temperature signal indicating a temperature in excess of a temperature threshold.
Claims20
A fuel system for a vehicle, comprising:
- a fuel tank configured to provide fuel to an engine of the vehicle;
- a shutoff valve configured to selectively restrict a flow of the fuel along a flow path between the fuel tank and the engine;
- a temperature sensor configured to monitor a temperature of at least one of the engine of the vehicle or a temperature associated with a body area of the vehicle and provide a temperature signal;
- and
- a controller coupled to the temperature sensor and the shutoff valve, wherein the controller is configured to control the shutoff valve to restrict the flow of the fuel in response to the temperature signal indicating a temperature in excess of a temperature threshold.
A fuel system for a vehicle, comprising:
- a fuel tank configured to provide fuel to an engine of the vehicle;
- a shutoff valve configured to selectively restrict a flow of the fuel along a flow path between the fuel tank and the engine;
- a proximity sensor positioned to monitor a position of an object within a surrounding environment;
- and
- a controller coupled to the proximity sensor and the shutoff valve, wherein the controller is configured to control the shutoff valve to restrict the flow of the fuel based on the position of the object.
A fuel system for a vehicle, comprising:
- a fuel tank configured to provide fuel to an engine of the vehicle;
- a shutoff valve configured to selectively restrict a flow of the fuel along a flow path between the fuel tank and the engine;
- a pressure sensor positioned along the flow path and configured to monitor a pressure of the flow of the fuel;
- and
- a controller coupled to the pressure sensor and the shutoff valve, wherein the controller is configured to:
- identify leakage of the fuel based on the pressure of the fuel falling below a pressure threshold, the pressure threshold relating to an expected operating pressure of the fuel when the fuel is flowing between the fuel tank and the engine;
- and
- control the shutoff valve to restrict the flow of the fuel in response to identifying the leakage of the fuel.
