Method for determining water load of air filter of internal combustion engine by control unit, involves carrying out determination of water load depending on signal of windshield wiper system correlating to existing rain intensity

摘要

The method involves carrying out determination of the water load depending on a signal of the windshield wiper system (4) of the motor vehicle (10) correlating to the existing rain intensity. The wiping frequency of the wiper of a windshield wiper system of the motor vehicle is represented by the signal of the windshield wiper system or the signal of the rain sensor (6) of the motor vehicle driving the windshield wiper system. The speed of the motor vehicle, the air flow through the air filter are additionally detected for determining the water load of the air filter (3). An independent claim is included for a method for operating an internal combustion engine with a turbocharger.
