Patent ID: 6898928

Claim:
A method for influencing an exhaust gas temperature in an internal combustion engine, the method comprising: determining whether an exhaust gas temperature exceeds a preset maximum temperature; if it is determined that the exhaust gas temperature does not exceed the maximum temperature then performing the following: determining a setpoint temperature according to a prioritization scheme, the prioritization occurring such that a temperature limitation for component protection has a highest priority; and determining whether the exhaust gas temperature exceeds the setpoint temperature; wherein if the exhaust gas temperature exceeds the setpoint temperature, performing at least one of deactivate heating measures and activate cooling measures, and wherein if the exhaust gas temperature does not exceed the setpoint temperature, performing at least one of activate the heating measures and deactivate the cooling measures; and if it is determined that the exhaust gas temperature exceeds the maximum temperature, performing at least one of deactivate the heating measures and activate the cooling measures.
