摘要： An exhaust gas recirculation (EGR) system is provided. The EGR system includes an engine having an intake manifold. The intake manifold is adapted to receive intake air from an aftercooler. The EGR system also includes an exhaust manifold. The exhaust manifold is adapted to receive exhaust gas from a plurality of cylinders of the engine. The EGR system further includes an EGR line. The EGR line is fluidly coupled between the intake manifold and the exhaust manifold. The EGR system includes an EGR valve disposed in the EGR line. The EGR system also includes a pressure line. The pressure line is coupled between the intake manifold and the EGR valve. The EGR valve is movable to an open position from a closed position, based on an intake pressure communicated to the EGR valve via the pressure line.

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 the 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 the 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： Intake noise suppression techniques for a forced-induction engine having a low pressure exhaust gas recirculation (LPEGR) system configured to recirculate exhaust gas produced by the engine to an intake system of the engine via an EGR port comprise receiving, from a mass air flow (MAF) sensor of the engine, a MAF signal indicative of measured airflow through the intake system, detecting, based on the MAF signal, intake system conditions that are indicative of audible noise, and in response to detecting the detected intake system conditions that are indicative of audible noise, at least partially closing a differential pressure (dP) valve to mitigate or eliminate the intake system conditions and the corresponding audible noise, wherein the MAF sensor is disposed in the intake system upstream from the dP valve.

摘要： A method of controlling the air supply to a scavenged internal combustion engine having a blower for suppling air thereto and bypass means for allowing a bypass air flow from the outlet side of the blower to the inlet side thereof, the method including regulating the bypass air flow through the bypass means to provide a variable rate of air flow therethrough and regulating the flow of ambient air to the blower to thereby control the pressure of the intake air supply to the blower and controlling a supply of recirculated exhaust gas introduced upstream of the blower by controlling the flow rate of ambient air to the blower such that a requisite pressure is generated upstream of the blower to thereby control the exhaust gas flow rate.
