Abstract: A valve control device controls a valve drive mechanism on the basis of a degree-of-opening signal for a valve and a startup signal for an engine, and includes: a drive signal generating unit that, when it is determined on the basis of the startup signal that the engine is stated, generates a test drive signal for test-driving the valve before the generation of a normal drive signal associated with normal driving of the valve; and an abnormality determining unit that, on the basis of the degree-of-opening signal during the test driving, determines whether or not an abnormality has occurred in the drive mechanism. The drive signal generating unit stops generating the test drive signal and the normal drive signal when the abnormality determining unit determines that the abnormality has occurred in the drive mechanism.

Abstract: A valve control device performs feedback control of a drive mechanism for a wastegate valve provided for a supercharger of an engine on the basis of a sensor signal indicating a real degree of opening of the wastegate valve and a target degree of opening of the wastegate valve, and includes a gain setting unit configured to set different control gains when the wastegate valve is closed and when the wastegate valve is opened.

Abstract: A valve control device controls an actuator for operating a valve based on a signal indicating a degree of opening of the valve and a signal indicating starting of an engine for which the valve. The valve control device includes a fully closed learning processing unit configured to learn a seated position at which a valve body is seated on a valve seat whenever the engine is started on the basis of the startup signal and the degree-of-opening signal, and a target value setting unit configured to set a soft-landing initiation position when the valve body is seated based on the seated position and set a target value with the valve body is decelerated from the soft-landing initiation position, and the valve body is seated at a predetermined seating speed. A control driving unit is configured to generate a drive signal based on the target value and the degree-of-opening signal.

Abstract: A valve control device includes a drive circuit for supplying a drive signal to an actuator adjusting an opening degree of a valve via a prescribed transmission line, generates a PWM signal on the basis of a target opening degree supplied from the outside and a sensor signal that indicates a real opening degree of the valve, and supplies the PWM signal to the drive circuit. The valve control device includes a disconnection detection unit which detects, on the basis of the PWM signal and a monitor signal of the drive signal, whether the transmission line is disconnected.

Abstract: Provided is an exhaust gas purification catalyst that combines reduction of pressure loss and enhancement of purification performance. This invention provides an exhaust gas purification catalyst comprising a wall-flow-type substrate and first and second catalytic layers. The first catalytic layer is provided to the interior of a partition wall, in contact with an entrance cell, from an exhaust inlet-side end in the running direction, having a length L1 less than Lw. The second catalytic layer is provided to the interior of a partition wall, in contact with an exit cell, from an exhaust outlet-side end in the running direction, having a length L2 less than Lw. An internal portion of partition wall in contact with entrance cell has a substrate-exposing segment near the exhaust outlet-side end.
