ABSTRACT:
An auxiliary vehicle heater includes a combustion air fan, an intermittently rotating, absorbent wick, a glow plug for initiating combustion and a water jacket surrounding a combustion chamber. Fuel is supplied to the rotating wick by a metering pump and the hot combustion gases enter the combustion chamber and give up heat to the vehicle coolant surrounding it in the water jacket. The coolant is then pumped to the heater core of the vehicle heater. A thermocouple in the exhaust passage of the combustion chamber senses the exhaust temperature and three thermostats in the water jacket provide temperature data to a microprocessor which controls operation of the heater in response to sensed conditions and operator commands.
