  • Patent number: 9890718
    Abstract: A control apparatus for an internal combustion engine of this invention includes: a turbo-supercharger; an exhaust gas purifying catalyst disposed in an exhaust passage on the downstream side of a turbine; and a WGV capable of opening and closing an exhaust bypass passage that bypasses the turbine. At the time of a catalyst warm-up request, catalyst warm-up control that opens the WGV and retards the ignition timing is executed. If the sensitivity of control of an intake air amount by a throttle valve is high, the intake air amount is controlled using the throttle valve during execution of the catalyst warm-up control. If the control sensitivity is low, the intake air amount is controlled using the WGV during execution of the catalyst warm-up control. When the WGV degree of opening is controlled toward a closed side during execution of the intake air amount control using the WGV, a retard amount of the ignition timing is increased.

At least one valve is configured to open and close the opening to selectively allow exhaust gas to pass from the exhaust passage to the space through the at least one opening. The space may be fluidly connected to at least one entry passage of an exhaust stack. In addition, the at least one opening and the at least one entry passage may be positioned on opposite sides of the exhaust passage.

  • Patent number: 9605608
    Abstract: In the control device, a relationship of a throttle-upstream pressure with respect to an exhaust-gas amount is used in a state where a supercharge pressure becomes the lowest by a WG-instruction value with respect to a WGV-control component 220 for driving a WGV 33a provided at a bypass passage 33 bypassing a turbocharger 32, and a relationship of a throttle-upstream pressure with respect to an aperture of a throttle valve 23, a rotational speed of an engine, and an intake-manifold pressure is used, and any of the throttle-upstream pressures, whichever is higher, being calculated in accordance with each of the relationship, is defined as a throttle-upstream-estimation value, whereby the throttle-upstream pressure is estimated by a cheap means with high accuracy so as to control the engine.

  • Patent number: 9605604
    Abstract: Various systems and methods for controlling a turbocharger of an engine via a wastegate are described. In one example, the wastegate is adjusted according to a difference between the boost pressure and the atmospheric pressure. In this manner, the interdependency between controlling the boost pressure and using the boost pressure to actuate the wastegate in a boost-based wastegate configuration may be reduced.

  • Patent number: 9567923
    Abstract: A control device to detect abnormality of a supercharging pressure sensor accurately in an internal combustion engine equipped with a supercharger that can change a supercharging pressure by operation of an actuator. The control device operates an actuator so that a supercharging pressure measured by a supercharging pressure sensor becomes a target supercharging pressure, acquires a measured value of a flow rate of air flowing in an intake passage, and calculates an estimated supercharging pressure based on the measured air flow rate. The control device sets a first abnormality flag when a first simultaneous inequality is established, which is a simultaneous inequality evaluating magnitude correlation between the measured supercharging pressure, the target supercharging pressure and the estimated supercharging pressure, and is not established when the supercharging pressure sensor is normal.

  • Patent number: 9562468
    Abstract: A method for mounting and setting an actuator of an exhaust gas turbocharger and a suitable electric actuating device are provided. The actuating device has an axially movable actuating rod which is connected to a coupling element which for its part is connected via a pivot pin to an actuation section of a bypass valve, the actuation section being configured as a lever arm. In order to set the desired closed position of the bypass valve during a predefined actuation of the actuating device, the coupling element is first connected to the actuating rod while still being displaceable. Before the fixing, the position of the actuating device which corresponds to the closed position is set by application of the corresponding voltage to the electric actuating device. Subsequently, a prestressing force is applied to the coupling element coaxially with respect to the actuating rod via a pneumatic actuator.
