Abstract

See full text

A method is provided for operating a fuel-operated vehicle heater (10) during a start phase of combustion operation. The heater includes a combustion air feed device (26) feeding air and a fuel feed device (22) feeding fuel (B) to a burner area (12) with a combustion chamber (16). An electrically energizable ignition element (32) ignites a fuel/air mixture formed. The method includes energizing the ignition element (32) in a preheating phase prior to the fuel feed, at a time of entry into an ignition phase, detecting electrical resistance of the ignition element (32) and determining a desired resistance based on the electrical resistance of the ignition element (32) detected and operating the ignition element (32) in a resistance-regulating operating mode during the ignition phase such that an actual resistance of the ignition element (32) is in the range of the determined desired resistance of the ignition element (32).
