(EN) Control system of internal combustion engine
要約
(EN)

A control system of an internal combustion engine is provided with an air flowmeter which is arranged in an engine intake passage, has a transition period from the initial operating state to the end operating state for obtaining the output value of the air flowmeter in the period from the time of startup of the internal combustion engine to when the warmup operation ends, calculates the cumulative air amount in the transition period from the detected output value of the air flowmeter, and uses the calculated cumulative air amount and the reference intake air amount corresponding to the transition period as the basis to correct the output value of the air flowmeter.
