摘要： A valve assembly comprises: a valve housing comprising an interior cavity having upstream side and a downstream side; and a valve member movable within the valve housing between a closed position in which flow between the upstream side and the downstream side is prevented or substantially prevented and one or more open positions in which flow between the upstream side and the downstream side is enabled. The valve assembly further comprises: a sensor mounting flange on an exterior surface of the valve housing; a first bore in the valve housing linking the upstream side of the valve housing and the sensor mounting flange; and a second bore in the valve housing linking the downstream side of the valve housing and the sensor mounting flange; such that a sensor configured to measure a differential between the upstream side and the downstream side is mountable directly on the valve assembly.

摘要： This engine system is provided with a throttle device, an EGR valve, and an ECU. The ECU diagnoses an abnormality of the EGR valve on the basis of an operating state during an engine deceleration, and diagnoses combustion deterioration of an engine on the basis of a crank angle speed change during the engine deceleration (not during a fuel cut-off). The ECU executes an engine stall avoidance control with the throttle device when it is determined there is an abnormality in the EGR valve, makes a final determination that the EGR valve has an abnormality and continues the engine stall avoidance control when it is determined thereafter that there is combustion deterioration, and makes a final determination that the EGR valve is normal and cancels the engine stall avoidance control when it is determined that there is no combustion deterioration.

摘要： A valve includes a valve body having an exhaust gas inlet and an exhaust gas outlet, the valve body defining an exhaust gas circulation passage between the exhaust gas inlet and the exhaust gas outlet. A flap is arranged in the valve body and a shaft drives the flap in rotation with respect to the valve body. At least one guide bearing guides the drive shaft of the flap for rotation relative to the valve body. The guide bearing is engaged through an orifice of the valve body, with an inner end of the guide bearing being located inside the valve body. A first tube is engaged in one of the exhaust gas inlet and exhaust gas outlet and abuts against the inner end of the guide bearing.

摘要： A hot gas exhaust recirculation valve includes a housing containing a duct for conducting gases, a drive chamber, and a valve stem which is mounted in the housing. The valve stem can be displaced in its longitudinal direction thereof and extends from the drive chamber into the duct. The end of said valve stem that is situated in the drive chamber is coupleable to a drive device. A closing body is fastened to the other end of said valve stem. The closing body is situated in the duct and has a closed position in which it separates an upstream section of the duct from a downstream section of the duct. A sealing ring surrounds the valve stem and is arranged between the duct and the drive chamber. The valve stem is supported within two bearing bushings that are spaced apart from each other, between which the sealing ring is arranged.

摘要： A controller is used in an internal combustion engine provided with an EGR device recirculating some of exhaust gas flowing in an exhaust passage to an intake passage as EGR gas. The EGR device includes an EGR passage and an EGR valve. The controller includes a CPU that controls opening and closing of the EGR valve. The CPU executes determining process of determining whether the temperature of the internal combustion engine is about the same as the outside air temperature, and an axis displacement eliminating process of opening and closing the EGR valve when it is determined that the temperature of the internal combustion engine is about the same as the outside air temperature in the determining process during the operation stop of the internal combustion engine.

摘要： An exhaust gas control valve for regulating a flow of exhaust gas includes a housing having an interior wall defining a housing interior, a yoke disposed in the housing interior and having a length and an axis extending along the length, with the yoke being moveable between a first and second yoke position. The exhaust gas control valve further includes a valve member including a valve shaft and a valve body. The valve member is moveable between a first valve position and a second valve position. The exhaust gas control valve also includes a retainer coupled to the yoke, and a biasing member disposed in the housing interior and coupled to the yoke and the retainer to bias the yoke and the retainer in opposite directions, with the biasing member being configured to prevent free play of the yoke and the valve member with respect to said housing.
