摘要： In a control method of an internal combustion engine exhaust gas control system which is applied to a hybrid vehicle that is powered by an internal combustion engine and an electric motor, an exhaust throttle valve., provided downstream of an exhaust gas control catalyst, is controlled to reduce its opening amount to a target opening amount when it is determined that warm-up control of the internal combustion engine needs to be executed. Next, a target injection quantity of fuel necessary to increase the temperature of exhaust gas flowing into the internal combustion engine to a target exhaust gas temperature is calculated. Then, assist torque from the electric motor is adjusted so that the sum of torque from the internal combustion engine when the fuel injection quantity has been set to the target injection quantity and the assist torque substantially equals a required torque.

摘要： A control device for an engine provided with a turbocharger properly uses a parameter used for controlling a center-of-gravity position of a heat generation rate determined by a heat generation rate as the amount per unit crank angle of heat generated by combustion of fuel depending on operating situations of the engine and a vehicle in which the engine is mounted. Specifically, an increase in a turbocharging pressure of the turbocharger is executed when a rotational speed of the engine and a speed of the vehicle in which the engine is mounted are lower than predetermined reference values in a case where the center-of-gravity position of a heat generation rate is further on a retard side than a predetermined crank angle and one or both of an increase in a fuel injection pressure and advancing of a fuel injection timing are executed when the rotational speed of the engine or the speed of the vehicle in which the engine is mounted are equal to or higher than the predetermined reference values in the case where the center-of-gravity position of a heat generation rate is further on the retard side than the predetermined crank angle. Then, fuel economy can be improved by the center-of-gravity position of a heat generation rate being maintained at a predetermined fixed value regardless of a load of the engine and/or the engine rotational speed while an increase in noise and vibration a user feels uncomfortable with is suppressed.

摘要： A valve device includes a body (4) in which a gas flow passage is provided; and a check valve (16) provided in the gas flow passage, the check valve (16) including a poppet (84) and a valve seat. The poppet (84) excluding a block portion (91) is in a form of a hollow shaft, the block portion (91) being located at a distal end of the poppet (84) and having a taper shape, and the poppet (84) has at least one side hole (95) that provides communication between an inside and an outside of a portion of the poppet (84), the portion being in the form of the hollow shaft. The at least one side hole (95) extends obliquely with respect to a central axis line of the poppet (84) such that the at least one side hole (95) extends along a gas flow direction inclined with respect to a direction in which the poppet (84) moves when the check valve (16) opens.

摘要： The invention relates to a control apparatus of an engine. The apparatus carries out a minute-injection for injecting a minute amount of a fuel so as not to generate an engine torque when a required engine load is zero. The apparatus calculates at least one coefficient for correcting a heat release gravity position calculated when the minute-injection is carried out such that it corresponds to its base position and/or for correcting a heat release rate corresponding the gravity position calculated when the minute-injection is carried out such that it corresponds to its base rate. When the required engine load is larger than zero, the apparatus controls the gravity position corrected by the coefficient to its target position.

摘要： A valve element (12) of a pressure reducing valve includes a taper portion (23) seated on an inner periphery of a valve hole (31). The valve hole (31) includes a first area (33), a second area (34) and a third area (35) in order from an upstream side. The first area (33) is provided such that, when the valve element (12) is open, the height of a passage defined between the first area (33) and the taper portion (23) gradually reduces toward a downstream side. The second area (34) is provided such that the height of a passage defined between the second area (34) and the taper portion (23) is constant when the valve element (12) is open and the entire second area (34) contacts the taper portion (23) when the valve element (12) is closed. The third area (35) is provided such that, when the valve element (12) is open, the height of a passage defined between the third area (35) and the taper portion (23) gradually increases toward the downstream side.
