A method for starting the combustion operation of a vehicle heater includes: in an ignition phase after generating a start command, operating an air conveyer for conveying combustion air into the combustion chamber at an ignition phase speed, and operating a fuel conveyer for conveying fuel into…
A heating system, more particularly for heating a motor vehicle, including a fuel-operated heating device and a sensing unit, which is configured to sense the presence of fuel in the heating device at least for a first case in which there is no flame formation, more particularly both for the first…

A combustion chamber assembly unit for a fuel-operated vehicle heater includes a mixing chamber () extending in a direction of a combustion chamber assembly unit longitudinal axis (L) for generating an air/fuel mixture. A fuel feed device () feeds fuel to the mixing chamber () and a combustion air…
In a control method for the switch-on function sequence of a fuel-operated heating device, this comprises the following time periods: a pre-run phase (VPh) beginning with the switching on of the heating device, during which only outside air but no fuel is supplied to the combustor chamber for…
The method involves having a starting procedure in a starting phase of pre-determined length of time with an electrically excitable heating arrangement (24, 26) and in a second starting phase at expiration of the first starting phase fuel is mixed with air for burning. The starting procedure with…
Method for operating the heating system in a motor vehicle whereby the outputs of sensors upstream and downstream of a heat exchanger region are used to control the heat output of a heat source supplying heat to the heat exchanger region. An Independent claim is made for a heating system comprising…
The heating system has at least one first heating device (10) and at least one second heating device (12), at least one flow path between the first and second heating devices and at least one auxiliary fan (50) for producing a flow from the second heating device to the first heating device. The…
The auxiliary heating device (16) has a fuel supply (22) for supplying fuel to a burner (20) of the auxiliary heating device (16) and a control device (28) for controlling the operation of the auxiliary heating device (16). In order to further reduce the pollutant emissions and fuel consumption of…
