Abstract
A cleaning apparatus for a burner on a motor vehicle energizes a heater of a fuel atomizer for heating and atomizing fuel, when fuel supply to the fuel atomizer is shut off and the speed of rotation of the engine on the motor vehicle is higher than a prescribed level, so that carbon deposits on and in the fuel atomizer will be burned out and removed.
Claims10
A cleaning apparatus for a burner on a motor vehicle having an engine mounted thereon, the burner including a fuel atomizer having a heater for heating and atomizing supplied fuel, and an igniting means for igniting the atomized fuel injected by the fuel atomizer, said cleaning apparatus comprising:
- speed detecting means for detecting the speed of rotation of the engine mounted on the motor vehicle and for providing a speed signal;
- fuel detecting means for detecting whether fuel is supplied to the fuel atomizer or not and for providing a fuel signal;
- and
- A controller, coupled to said speed detecting means and said fuel detecting means, for controlling energization of the heater of the fuel atomizer when the fuel signal from said fuel detecting means indicates that the supply of fuel is shut off, and the speed signal from said speed detecting means indicates that the speed of rotation of the engine is higher than a preset level.
A motor vehicle heater mounted in a motor vehicle having an engine, to heat the passenger compartment of the motor vehicle, comprising:
- means for supplying fuel;
- a burner for igniting the supplied fuel, said burner having deposits formed thereon, said burner including:
- a fuel atomizer having means for heating the supplied fuel, said fuel atomizer atomizing the supplied fuel;
- and
- igniting means for igniting the atomized fuel produced by the fuel atomizer;
- means for transferring heat from the ignited atomized fuel to the passenger compartment of the motor vehicle;
- speed detecting means for detecting the speed of rotation of the engine and for generating a speed signal;
- fuel detecting means for detecting whether fuel is being supplied to said fuel atomizer and for generating a fuel signal;
- and
- control means for controlling the energization of said heating means in said fuel atomizer when the fuel signal from said fuel detecting means indicates that fuel is not being supplied to said fuel atomizer and the speed signal from said speed detecting means indicates that the speed of rotation of the engine is higher than a predetermined speed, so that when said heating means is energized by said control means, the deposits on said burner are burned off.
