Carburetor venturi vacuum and engine manifold vacuum controlled exhaust gas recirculating

The engine has a duct connecting the exhaust gas crossover passage to the intake manifold, the duct normally being closed by a load and speed sensitive valve whenever manifold vacuum acting on the valve exceeds an amplified carburetor venturi vacuum acting on the valve in the opposite direction; the...
