Control system for internal combustion engine
First Claim
1. A control system for an internal combustion engine having fuel injection means for injecting fuel to an intake pipe or a combustion chamber of said engine, comprising:
- intake gas state parameter detecting means for detecting intake gas state parameters indicative of a state of intake gases supplied to said engine;
demand value calculating means for calculating demand values of the intake gas state parameters according to operating condition parameters indicative of an operating condition of said engine;
intake gas state control means for controlling the intake gas state so that the intake gas state parameters coincide with the demand values; and
fuel injection control means for calculating a control value according to the operating condition parameters and deviations of the intake gas state parameters from the demand values, and for controlling an amount of fuel injected by said fuel injection means according to the control value.

Abstract
A control system for an internal combustion engine having at least one fuel injection valve for injecting fuel to an intake pipe or a combustion chamber of the engine. Intake gas state parameters indicative of a state of the intake gases supplied to the engine are detected. Demand values of the intake gas state parameters are calculated according to operating condition parameters indicative of an operating condition of the engine. The intake gas state is controlled so that the intake gas state parameters coincide with the demand values. A control value is then calculated according to the operating condition parameters and deviations of the intake gas state parameters from the demand values. Accordingly, an amount of fuel injected by the at least one fuel injection valve is controlled according to the control value.
