Abstract:
A control apparatus for an internal combustion engine, which is capable of calculating engine parameters required for controlling the engine, particularly a combustion parameter, based on a result of detection by an in-cylinder pressure sensor, accurately in real time, thereby making it possible to improve the controllability of the engine. The control apparatus includes an in-cylinder pressure sensor for detecting in-cylinder pressure PCYL in a cylinder, a plant model provided in an electronic control unit and including a combustion model for calculating a heat release rate using the detected in-cylinder pressure PC for calculating engine parameters (the heat release rate, intake manifold pressure Pin, EGR temperature Iegr, EGR pressure Pegr) indicative of states of the engine, including the heat release rate, and an engine controller provided in the electronic control unit, for controlling the engine using the engine parameters calculated by the plant model.

Claim (Index 8):
The control apparatus according to claim  2 , wherein the engine includes a fuel injection valve for injecting fuel directly into each cylinder, and\n wherein the in-cylinder pressure sensor is integrally provided on the fuel injection valve.
