摘要： A bottom assembly unit for a vaporizing burner combustion chamber assembly unit, especially for a vehicle heater, includes a bottom part (24) with a bottom wall. A porous evaporator medium (44) at least partially covers the bottom wall on a front side (42) positioned such that it faces a combustion chamber (20). A ring-shaped holding part (34) has a contact area (40) touching the porous evaporator medium (44). The contact area has a contact section (62) extending radially inwardly from a holding part circumferential wall (36) and extends over the porous evaporator medium (44) in a radially outer area (66). A plurality of contact projections (68) are arranged at spaced locations from one another about the longitudinal axis and extend in the direction of the porous evaporator medium. The porous evaporator medium (44) is pressed by the contact projections (68) in a radially outer area (66) against the bottom wall.

摘要： A fuel-operated vehicle heater, combustion chamber assembly unit includes a combustion chamber housing (14) having a combustion chamber bottom (18) and a combustion chamber circumferential wall (16) extending in a housing longitudinal axis (L) direction to define a combustion chamber (20). A porous evaporator medium (60) is on the combustion chamber circumferential wall or/and the combustion chamber bottom, at an inner side facing the combustion chamber. A fuel feed line (62) feeds liquid fuel into the porous evaporator medium. A first combustion air feed device (68), associated with the combustion chamber bottom, feeds primary combustion air (VP) into a first combustion zone (50) at which the porous evaporator medium is arranged. A second combustion air feed device (70), following the first combustion zone in the housing longitudinal axis direction feeds secondary combustion air (VS) into the combustion chamber at an axially spaced location from the first combustion zone.

摘要： A fuel-operated vehicle heater includes a burner area (12) with a combustion chamber (14); a fuel pump (24); and a combustion air blower (28). A pressure sensor (38) detects a feed back pressure. An actuating unit (36) actuates the fuel pump (24) with a predefined value of a pump operating variable, and actuates the combustion air blower with a predefined value of a blower operating variable. A heater process includes detecting the feed back pressure in case of a feed operating state set during the combustion operation and comparing the detected feed back pressure (Pe) with an expected feed back pressure (PE) for the set feed operating state. If the detected feed back pressure deviates from the expected feed back pressure the pump operating variable is changed such that the feed back pressure changes toward the expected feed pressure and/or essentially corresponds to the expected feed back pressure.

摘要： 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).
