EXHAUST GAS RECIRCULATION CONTROL MECHANISM

摘要

A lever is mounted pivotally on a spacer located between the carburetor and the intake manifold of a reciprocating internal combustion engine and a cam is mounted pivotally on the lever. The cam positions a poppet-type valve that determines exhaust gas recirculation rate. A vacuum motor responding to intake manifold pressure acts on the lever to position the cam indirectly and carburetor throttle linkage is connected directly to the cam.
