Abstract
An arrangement for space heaters for motor vehicles, which are fired with liquid fuel including, (depending on the type of burner used), a glow plug for either igniting a fuel/air mixture and/or vaporizing fuel. Only one type of glow plug, i.e., a glow plug designed for a 12-V electrical system, is normally employed. If the motor vehicle has a 24-V battery, a compensating resistor, which has the same electrical resistance as the glow plug, is connected in series with the glow plug. The amount of electrical energy converted into heat in the compensating resistor is practically equal to that transformed in the glow plug. The compensating resistor is integrated within the burner housing, in which case it is located in the flow path of the combustion air and is properly cooled by the air flowing past it, to provide a safe trouble free and space-saving arrangement.
