  • Boost wastegate device for EGR assist
    Patent number: 7254948
    Abstract: An apparatus and method for controlling exhaust gas recirculation flow. The apparatus and method uses a pressure-bleeding device, such as a wastegate valve, to change the pressure in an internal combustion engine in order to alter the flow rate of the exhaust gas through an exhaust gas recirculation conduit. In one form, the invention includes an inlet conduit connected to an intake manifold of an internal combustion engine and an exhaust conduit connected to exhaust manifold of an internal combustion engine. The pressure-bleeding device is operatively coupled to the intake conduit. Altering the pressure in the intake conduit changes the pressure across the entire system. This change in pressure in the entire system results in a change in pressure across the exhaust gas recirculation conduit. Therefore, a flow is created through the exhaust gas recirculation conduit and can be controlled using the intake side pressure bleeding device.
