Abstract: A control circuit includes a computing unit, which computes a target oil pressure, a duty output unit, which outputs a drive electric current based on a result of computation of the computing unit, and a dither output unit, which applies a dither signal to a linear solenoid. The dither signal is added to the drive electric current outputted from the duty output unit and is applied to the linear solenoid. The dither output unit always applies the dither signal to the linear solenoid throughout an operation. The dither output unit reduces a pulse height of the dither signal in a dead zone in comparison to a pulse height of the dither signal in a control zone. In this way, even when an axial position of a spool is changed between the control zone and the dead zone, the amplitude of dither of the spool can be made generally constant. Thereby, it is possible to limit a change in an output oil pressure.

Abstract: An ECU controls waste heat quantity of an engine according to a required heat quantity in response to a heat-utilize requirement. The ECU controls a valve opening period of an intake valve based on an engine driving condition and an ignition timing based on a most efficient timing at which fuel economy is highest. The ECU determines whether there is an ignition advance margin relative to the most efficient timing. When there is no margin, an actual compression ration of the engine is decreased by advancing or retarding a valve close timing of the intake valve and the ignition timing is advanced relative to the most efficient timing in order to increase the waste heat quantity.

Abstract: A sub-injector injects liquid fuel into a vaporized-fuel chamber of a vaporized-fuel tank. The injected liquid fuel is vaporized in the vaporized-fuel chamber. The generated vaporized fuel is supplied to a combustion chamber through a vaporized-fuel passage. A supply of the vaporized fuel to the combustion chamber is controlled by a purge valve. Thereby, the vaporized fuel can be precisely supplied to the engine at a start of engine, so that emission can be reduced.

Abstract: An engine control system includes an engine that outputs a rotation of a crankshaft through a torsional damper; a calculation portion that calculates a value of engine torque based on an angular acceleration of the crankshaft and a moment of inertia of the crankshaft; and a correction portion that calculates a correction value based on a torsional angle of the torsional damper, and corrects the calculated value of the engine torque using the correction value.

Abstract: A fuel supply device includes: an injector that injects and supplies fuel to an engine; a pressure accumulator communicating with a cylinder of the engine through a communication passage; a valve that opens or closes the communication passage; and a controller that controls the injector and the valve. When the engine is rotated, an air-fuel mixture is compressed in the cylinder, and an accumulating portion of the controller accumulates the air-fuel mixture in the pressure accumulator. When the engine is restarted, a supplying portion of the controller supplies the air-fuel mixture accumulated in the pressure accumulator to the cylinder.

Abstract: A crankshaft of an engine is connected to a carrier shaft of a planetary gear via a damper. The damper includes a torsion member generating elastic force for suppressing relative rotation, when the crankshaft and the carrier shaft are relatively rotated. A control unit estimates engine torque with using rotation angular acceleration of the crankshaft calculated from a detected value of an engine speed sensor, and corrects the estimated engine torque with a correction term of the elastic force of the damper calculated based on a damper torsional angle. Then, the control unit diagnoses an abnormality of the engine based on the estimated engine torque after correction.
