ABSTRACT:
An improved intake manifold structure for internal combustion engines includes a distribution chamber having an upper sub-chamber leading to a carburetor and a lower sub-chamber communicating with the upper sub-chamber through a communication hole. A plurality of branch passages extend from the lower sub-chamber to a plurality of combustion chambers. An air-fuel mixture fed from the carburetor to the distribution chamber is expanded successively in two steps to promote its atomization as it passes through the two sub-chambers, thus improving uniform distribution of the mixture to the respective branch passages. Engine exhaust gas is returned to the upper sub-chamber to further promote the atomization of the mixture.
