Abstract
Official abstract text for this publication.
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 case in which there is no flame formation and for a second case in which there is flame formation.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A heating system for heating a motor vehicle, comprising a fuel-powered heating device and a detection unit which is configured to detect the presence of fuel in the heating device at least in a first case in which there is no flame formation, wherein the detection unit is configured, in order to carry out the detection, to use an electrical power consumption of at least one ignition device within a corresponding calculation and/or comparison and/or analysis and further wherein a control device of the heating system is configured to carry out an additional start attempt, with a leaner mixture, when it is determined that flame formation is not present when fuel is present. 2 . The heating system as claimed in claim 1 , wherein the detection unit is configured, in order to carry out the detection, to use at least one operating parameter of the heating system. 3 . The heating system as claimed in claim 1 , wherein the detection unit is configured, in order to carry out the detection, to use at least one parameter which is assigned to the at least one ignition device of the heating device. 4 . The heating system as claimed in claim 1 , wherein a temperature of at least one ignition device can be controllable to a constant value. 5 . The heating system as claimed in claim 1 , wherein the detection unit is configured to detect whether flame formation has taken place when a fuel is present in the heating device. 6 . The heating system as claimed in claim 1 , wherein the detection unit is configured to detect the presence of fuel in the heating device in a second case in which there is flame formation. 7 . The heating system as claimed in claim 1 , wherein the at least one ignition device comprises at least one glow plug, whose power consumption is used. 8 . The heating device as claimed in claim 1 , wherein the electrical power consumption of the at least one ignition device is used in such a way that at least an increase in the electrical power consumption can be determined. 9 . The heating device as claimed in claim 1 , wherein the electrical power consumption of the at least one ignition device is used in such a way that an increase and a decrease in the electrical power consumption can be determined.
