ABSTRACT:
An exhaust gas recirculation flow control apparatus is proposed for use in an exhaust gas recirculation system of an electronically controlled engine where flow from each of two exhaust manifold banks converges into a common area incorporating a port therein communicating to a passageway of an intake manifold with flow from each of the exhaust banks being balanced. The valve seat in the valve housing port and the valve body are tapered to provide a side seal of the valve body and the tapered seat as the valve is moved linearly into the port from the exhaust manifold side to isolate the banks from one another, as well as to control flow through the communication port under direction of an ECU.
