Abstract:
1. An internal combustion engine induction air volume calculating apparatus for calculating the volume of induction air supplied to an internal combustion engine via an air induction pipe, the apparatus comprising: a. an air flow meter for detecting the volume of induction air which passes a throttle valve disposed in the air induction pipe; b. an air induction pipe internal pressure sensor for detecting the internal pressure of the air induction pipe; c. determination unit for determining whether or not induction air other than the induction air volume so detected is supplied to the internal combustion engine based on the detected induction air volume and air induction pipe internal pressure; and d. correction unit for correcting the detected induction air volume when it is determined that induction air other than the induction air volume so detected is supplied to the internal combustion engine.
