System for measuring amount of air introduced into combustion chamber of internal combustion engine with avoiding influence of temperature dependent air density variation and pulsatile air flow
A system for measuring intake air amount to be introduced into an engine cylinder employs a throttle angle sensor as a basic intake air flow amount indicative factor. Basic intake air flow amount is derived on the basis of a throttle vale angular position and an engine speed. The basic intake air flow amount is corrected with taking delay factor to introduce the intake air past the throttle valve into the engine cylinder, and a temperature dependent factor compensating variation of air density depending upon the temperature condition.
