Abstract
An exhaust gas recirculating device having a regulator integrally formed with an air horn of the carburetor, a throttle body and an insulator, both secured to a carburetor flange, a groove cut on the underside of the carburetor flange, a plate interposed between the flange and the suction manifold, said groove and plate forming an exhaust gas recirculating passage, a variable throttle valve, a throttle valve, and a link means interconnecting the variable throttle valve and the throttle valve, whereby exhaust gas from the engine is recirculated to downstream of the throttle valve. With this invention the exhaust gas recirculating device can be incorporated into conventional carburetors with minor modifications on the carburetor.
