    摘要: A method for operating a soot sensor in the exhaust gas tract of an internal combustion engine. The soot sensor includes an inter-digital electrode structure to which a measurement voltage is applied. Soot particles from the exhaust gas flow deposit themselves on the inter-digital electrode structure and an measuring current is evaluated as a measurement for the soot concentration of the soot sensor. A heating element for burning clean the inter-digital electrode structure is provided. The method for operating the soot sensor has good measurement results and the shortest possible idle time. To this end, a point in time for burning clean the soot sensor is determined in accordance with the operational state of the internal combustion engine and then, the burning clean of the inter-digital electrode structure starts by heating the soot sensor by the heating element.

    摘要: 1-nonen-3-one is added to food, pharamaceutical, cosmetic and perfume compositions to flavor the products and so that they impart aroma. It is added particularly to dairy products and coffee extract for enhancing the aroma imparted by those compositions. The 1-nonen-3-one may be combined with other compounds which provide flavor and aroma, and the combined compounds are added to the compositions.

    摘要: A method for performing on-board functional diagnostics on a soot sensor of a vehicle and/or for detecting further components in the soot in a motor vehicle having an internal combustion engine. The soot sensor is electrically connected to an evaluation circuit with is permanently installed in the motor vehicle. In order to specify a method for performing functional diagnostics on a soot sensor and/or for detecting further components in the soot, with which method it is possible to detect a faulty soot sensor and/or further components in the soot in a cost-effective way, the evaluation circuit measures the temperature coefficient of the soot sensor and detects the defectiveness of the soot sensor and/or the presence of further components in the soot on the basis of the temperature coefficient of the soot sensor.
