BURNER HAVING A DEVICE FOR CONTROLLING FUEL COMBUSTION THEREIN

摘要

A burner (6) produces combustion gases which are fed to a heat exchanger (13) for heating air supplied by a blower (16) to the passenger compartment of a motor vehicle and are then discharged into an inlet manifold (1) of the engine of the vehicle. The burner includes a fuel atomizer (9) with a fuel atomizing glow plug (92) in a combustion chamber (71) and an igniting glow plug (10) in an ignition chamber (70). In order to control the atomization of the fuel and thus its combustion, the temperature of the burner is sensed by measuring by means of a detector (100), the resistance of a resistance wire, having a postive temperature coefficient of resistance, embededded in the ignition glow plug (10). The detector (100) sends a signal to a controller (21) which controls the electric power supplied to the atomizing flow plug (92) and hence its temperature. The controller (21) also receives signals from an atomospheric temperature sensor (12) since the atmospheric air temperature also affects the temperature in the conbustion chamber (71).
