摘要： An engine control unit includes pressure detector provided in a combustion chamber of the engine. A motoring pressure of the engine is estimated. A combustion starting time is detected when the difference between an internal pressure detected by the pressure detector and the pressure estimated by the ECU exceeds a predetermined value. When the internal pressure detected by the pressure detector reaches its peak after the combustion starting time has been detected, the crank angle at this time point is determined to correspond to the maximum internal cylinder pressure that is generated by combustion.

摘要： An in-cylinder pressure detection device for an internal combustion engine, which is capable of detecting an in-cylinder pressure accurately without being adversely affected by changes in the atmospheric pressure even when the atmospheric pressure changes. An in-cylinder pressure sensor detects pressure within a cylinder as a detected in-cylinder pressure. An ECU estimates pressure generated in the cylinder during a non-combustion period as a motoring pressure. An atmospheric pressure sensor detects an atmospheric pressure (PA). The ECU corrects the motoring pressure according to the atmospheric pressure and identifies correction parameters such that the difference between the detected in-cylinder pressure detected during a compression stroke of the engine and the corrected motoring pressure becomes minimum, and corrects the detected in-cylinder pressure by the identified correction parameters, to thereby calculate an in-cylinder pressure.
