Method for operating an internal combustion engine for favorable exhaust gas treatment

摘要

The invention discloses a method for operating a drive device (10), in particular in a motor vehicle, comprising an internal combustion engine (12) and at least one further drive assembly (28) which is not an internal combustion engine (12), wherein an exhaust gas from the internal combustion engine (12) is treated by means of an exhaust gas treatment system (16), and wherein it is checked whether the internal combustion engine (12) is in an operating point defined as favorable for the exhaust gas treatment, and wherein then if it is found that the internal combustion engine (12) is not in an operating point defined as favorable for the exhaust gas treatment, the operating point of the internal combustion engine (12) is brought using the further drive assembly (28) into a range defined as favorable for the exhaust gas treatment.

主权项

1. A method for operating a drive device (10), comprising an internal combustion engine (12) and at least one further drive assembly (28) which is not an internal combustion engine (12), wherein an exhaust gas from the internal combustion engine (12) is treated by an exhaust gas treatment system (16), the method comprising:
determining the internal combustion engine (12) is not in an operating point defined as favorable for the exhaust gas treatment; and bringing the operating point of the internal combustion engine (12) into the range defined as favorable for the exhaust gas treatment using the further drive assembly (28); wherein the operating point is defined as favorable for the exhaust gas treatment is determined using a temperature of the exhaust gas and a ratio of NO2 to NOx in the exhaust gas.
