Abstract
A control device of an internal combustion engine provided with throttle air passage calculating means for calculating an amount of throttle air passage through a throttle valve, excess air calculating means for calculating an amount of excess air to a cylinder corresponding to drop in air pressure in intake pipe due to an intake valve for that cylinder opening, cylinder air charge estimating means for estimating a cylinder air charge amount for each cylinder based on the amount of throttle air passage detected by the throttle air passage detecting means and an amount of excess air calculated by the excess air calculating means, and engine control means for controlling the internal combustion engine based on the cylinder air charge amount for each cylinder estimated by the cylinder air charge estimating means.
Claims11
A control device of an internal combustion engine, comprising:
- throttle air passage calculating means for calculating an amount of throttle air passage through a throttle valve,
- excess air calculating means for calculating an amount of excess air to a cylinder corresponding to a drop in air pressure in an intake pipe occurring due to pulsation of the air pressure due to an intake valve for that cylinder opening,
- cylinder air charge estimating means for estimating a cylinder air charge amount for each cylinder based on the amount of throttle air passage detected by said throttle air passage detecting means and an amount of excess air calculated by said excess air calculating means, and
- engine control means for controlling the internal combustion engine based on the cylinder air charge amount for each cylinder estimated by said cylinder air charge estimating means.
