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.

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： In order to stabilize a performance of a pump employed for processing in an inkjet printing apparatus such as sucking ink from a printing head with a low cost configuration and without the need of using any specific detecting unit, the following configuration is employed. Namely, a tube pump having a member with a curved surface aligned with a flexible tube for supporting the tube and a roller which moves while pressing (squeezing) the flexible tube is driven with a DC motor. To keep revolutions always constant, a current PWM control is employed for changing a power applied to the motor according to load fluctuations, and a phase of the roller is determined based on the current PWM value to manage a pressure generated by the pump and a discharge rate.

摘要： This invention relates to a printing apparatus and a conveyance control method capable of allowing even an arrangement having a plurality of conveyance rollers in a printing medium conveyance path to accurately control conveyance of a printing medium. According to this invention, a first encoder detects a conveyance amount by a first conveyance roller, provided in a conveyance path, for conveying a printing medium. A second encoder detects a conveyance amount by a second conveyance roller provided in the conveyance path in the conveyance direction of the printing medium at the downstream side of the first conveyance roller for conveying the printing medium. On the other hand, a signal output from the first or second encoder is selected on the basis of the position of the printing medium on the conveyance path. Conveyance of the printing medium is controlled on the basis of the selected output signal.
