Abstract
With a fluid fuel driven standard heating for motor vehicles, whose combustion chambers are equipped as vaporizer burners, a heater plug with open heater coils up to now would be installed in the usual way. What is disadvantageous for the operation, particularly in the starting, is the voltage dependence of such a heater plug. Also, with time an increasing carbonization would be established. According to the invention the vaporizing of the liquid fuel occurs under a seal by the use of a rod heater plug. The ignition can--independent of voltage--occur with the help of a spark plug (high voltage electrode). In a construction design the vaporizer is developed as a heat pipe, in which the rod heater plug is arranged.
