Abstract

PURPOSE: To accelerate the speed of the mixed air flow conducted through the branch path to improve the combusting capacity by connecting the suction ports in the throttle valve down stream of the multicylinder engine through the connecting path and the branch path, and by forming the end of the branch path into the funnel shape.
CONSTITUTION: Each throttle valve 22 of each cylinder which is provided near the suction port 5b of each suction path 15 with the carbureter 13 is connected to one another by a common shaft. The common connecting path 29 which extends in the longitudial direction of the engine is provided in the lower part of the suction path 15, and the branch connecting path 30b which opens into the suction port 5b is stretched out of the connecting path 29. The top end of the branch path 30b, which is arranged in the tangential direction against the suction valve 3b, is the funnel-shaped 31 to reduce the resistance and improve the speed of the flow in the path which leads to the suction port 5b through the branch path 30b.
