ABSTRACT:
Arrangement for calculating the fuel injection quantity for an internal combustion engine. An air mass meter has a heated sensor and an air temperature sensor. Since, during a stop condition of an internal combustion engine, any and all cooling by a mass stream of air is absent, the air temperature sensor is heated by the heated sensor when the air mass meter continues to be turned on. In order to eliminate the error in an output signal of the air mass meter that occurs when the internal combustion engine is restarted, the air mass meter is shut off during the stop condition of the internal combustion engine.
