Abstract
Methods and systems are provided for a fuel system. In one example, a method may include adjusting operation of a fuel-operated heater (FOH) and an exhaust system to regenerate the FOH. The operation may include flowing gases from the exhaust system to the FOH to return the FOH to a less coked state.
Claims17
A system, comprising:
- a fuel operated heater (FOH) fluidly coupled to an exhaust system of an engine and a vehicle interior cabin;
- and
- a controller comprising computer-readable instructions that when executed enable the controller to:
- direct exhaust gases from exhaust system to the FOH in response to a regeneration request;
- and
- crank the engine and flow engine compressed air to the FOH in response to the regeneration request being present when the engine is not combusting.

A system, comprising:
- a fuel operated heater (FOH) fluidly coupled to an exhaust system of an engine and a vehicle interior cabin;
- a differential pressure sensor coupled to an inlet and an outlet of the FOH;
- and
- a controller comprising computer-readable instructions that when executed enable the controller to:
- direct exhaust gases from exhaust system to the FOH in response to a regeneration request, wherein the regeneration request is in response to a pressure differential sensed by the differential pressure sensor.
2 more elements
A method, comprising:
- activating a fuel operated heater (FOH) for a threshold duration;
- deactivating the FOH;
- flowing exhaust gases from an engine to the FOH;
- and
- maintaining the FOH active and cranking the engine in response to the engine being unfueled.
