ABSTRACT:
A combustion heater system for use in a moter vehicle has a combustion chamber housing a combustion pad which is heated by a pre-glow plug for vaporizing a fuel that is supplied from a fuel tank through a solenoid-operated valve to the combustion pad. The combustion chamber is supplied with air from a fan, and houses a spark plug for producing sparks in the combustion chamber to ignite a fuel vapor emitted from the combustion pad. The combustion heater system has a control unit which energizes the pre-glow plug to heat the combustion pad, actuates the solenoid-operated valve to supply the fuel to the combustion pad, and actuates the fan to supply air to the combustion chamber. The control unit subsequently energizes the spark plug to produce sparks upon elapse of a preset period of time hereby to ignite the fuel vapor emitted from the combustion pad for producing flames in the combustion chamber. To extinguish the flames, the control unit inactivates the solenoid-operated valve to stop supplying the fuel to the combustion pad and subsequently inactivates the fan to stop supplying air to the combustion chamber.
