摘要： An exhaust gas recirculation valve assembly including a bushing and pintle shaft sub-assembly having a pintle shaft supported by a sleeve bushing, the contact area between the shaft and bushing being reduced such that coking deposits that form on the remaining contact area can be broken by the force of the valve actuator, thereby preventing sticking of the valve from coking accumulations. Either the shaft surface or the bushing surface is relieved in a pattern of incuse areas and residual bearing areas. A currently preferred pattern is a helix.

摘要： A method of controlling exhaust gas recirculation by means of an EGR valve (55). An electromagnetic actuator (41) is associated with a housing (47) to transmit movement of an actuator output (75) into reciprocating movement of the EGR valve in response to changes in an electrical input signal (95), and the method comprises generating (93) a compensator gain value to modify the electrical input signal (95). The improved method provides a valve position sensor (79) and generates a position signal (97) representing instantaneous valve position. The next step is storing (105) a first relationship (DCTHLD) of the electrical input signal (95) required to change the instantaneous valve position, then, during ongoing operation, generating (105) a then-current, second relationship (DC) of the electrical input signal (95) required to change the instantaneous valve position. Next is comparing (105) the second relationship (DC) to the first (DCTHLD) and generating (111) a corresponding difference factor, then using (111) that difference factor to modify (93) the compensator gain value correspondingly. This method enables the system to adapt to changes in system friction.

摘要： A control system for controlling an internal combustion engine having an exhaust gas recirculation mechanism consisting of an exhaust gas recirculation passage connected between the exhaust passage and the intake passage of the engine, and an exhaust gas recirculation valve provided in the recirculation passage for controlling an exhaust gas amount to be recirculated. Control parameter(s) of the engine are calculated according to operating conditions of the engine. An amount of change in the intake pressure between when opening the exhaust gas recirculation valve and when closing the exhaust gas recirculation valve, in the fuel-cut operation, is calculated. The abnormality of the exhaust gas recirculation mechanism is determined according to the amount of change in the intake pressure. The engine is controlled by using the control parameter suitable for a closed condition of the exhaust gas recirculation valve during a predetermined time period.

摘要： An automotive emission control valve, such as an EGR valve, has a solenoid for operating a valve element. The solenoid stator has an annular air gap disposed within an electromagnet coil. An annular wall of an armature is disposed in the air gap. The armature is displaced by magnetic flux in the air gap. The air gap is cooperatively defined by juxtaposed walls of the stator that are spaced radially a distance greater than radial thickness of the annular wall of the armature. The annular wall of the armature is disposed radially intermediate the stator walls and spaced from each stator wall. The radially inner stator wall is tapered. Lost-motion is present between the armature and valve element so that initial armature displacement is not transmitted to the valve element. Dimensions of the stator walls and armature at the air gap may be selected to improve linearity of operation.
