摘要 |
An in-cylinder pressure detection device for an internal combustion engine, which is capable of calculating a hysteresis amount properly to thereby detect in-cylinder pressure with high accuracy. The in-cylinder pressure detection device comprises an in-cylinder pressure sensor that detects in-cylinder pressure as a detected in-cylinder pressure. The in-cylinder pressure detection device estimates an in-cylinder pressure generated when combustion is not performed in the cylinder, as a motoring pressure, calculates a hysteresis amount indicative of a difference between the detected in-cylinder pressure and an actual in-cylinder pressure, based on the detected in-cylinder pressure and the motoring pressure obtained during the exhaust stroke of the engine, and corrects the detected in-cylinder pressure based on the calculated hysteresis amount. |
