摘要： An apparatus for controlling a lock-up clutch disposed in a drive system of an automotive vehicle which includes a lean-burn engine provided with a turbocharger. The apparatus is arranged to place the lock-up clutch in a fully engaged state and/or a slip control state while a running condition of the automotive vehicle is in a predetermined engaging area or slip control area of the lock-up clutch. The apparatus includes an engaging-area changing device operable to change the engaging area of the lock-up clutch, on the basis of a turbocharging pressure established by the turbocharger, and/or slip-control-area changing means for changing the slip control area, on the basis of the turbocharging pressure. Also disclosed is an apparatus for controlling a lean-burn engine provided with a turbocharger, which apparatus includes a device for changing a range of an air/fuel ratio of an air-fuel mixture of the engine for a given turbocharging pressure, on the basis of at least one of operating state and slipping state of the lock-up clutch.

摘要： Improved vanes of this invention are constructed for use within a variable geometry turbocharger assembly. Each vane comprises an inner airfoil surface oriented adjacent a turbine wheel, and an outer airfoil surface oriented opposite the inner airfoil surface. The inner and outer airfoil surfaces define a vane airfoil thickness. Each vane includes a leading edge positioned along a first inner and outer airfoil surface junction, a trailing edge positioned along a second inner and outer surface junction, a hole disposed within a first axial vane surface substantially parallel to an outer nozzle wall for receiving a respective post therein, and an actuation tab extending from a second axial vane surface opposite from the first vane surface. A key feature of improved vanes of this invention is that they have an airfoil thickness that is greater than 0.16 times a length of the vane as measured between the vane leading and trailing edges.

摘要： This invention provides a manual boost control valve for an automotive turbocharger. The valve communicates between the intake side and exhaust side of the turbocharger system and particularly communicates with a wastegate actuator that operates a wastegate at the exhaust side. The wastegate actuator operates the wastegate in accordance with the degree of airflow received through the valve, and the valve may be manually manipulated from within the interior of the automobile by a knob interconnected through a cable to a restriction coupling.

摘要： An engine with a charger, in which an intake passage is provided with a throttle valve which is electronically controlled to a target opening degree and the charger on the upstream side of the throttle valve, wherein a target supercharged pressure is corrected in a direction of eliminating a delay in the intake air amount based upon a difference between the target supercharged pressure of the charger and the supercharged pressure detected on the upstream side of the throttle valve, to thereby set a target supercharged pressure of the throttle valve based on the corrected target supercharged pressure. This suppresses a delay in the intake air amount caused by a delay in the change of the supercharged pressure during the transient period, makes it possible to accomplish acceleration/deceleration performance of good response, and suppresses a torque difference that occurs when the combustion system is changed over to the stratified charge combustion or to the homogeneous combustion.

摘要： A variable geometry turbocharger employs multiple vanes in the turbine inlet with a unison ring and integral cast wall in the turbine housing forming the nozzle walls. The unison ring incorporates actuation slots receiving tabs on the vanes for opening the closing the nozzle area upon rotation of the unison ring. An integral electrohydraulic actuator rotates the unison ring through a rack and pinion driven crank shaft with direct position feedback to the spring biased variable current solenoid via a cam on the crank shaft.
