Abstract
PURPOSE: To increase the filling efficiency to each cylinder by opening branched passages and the opening parts which communicate to a common communication passage, on the down stream side of the throttle valve arranged at each intake port part of a multicylinder engine and utilizing the pressure due to blowing-back.
CONSTITUTION: A throttle valve 22 is arranged in the vicinity of the intake port 5b of each intake passage 11 equipped with a carburetor 13, and each throttle vavle not shown in the figure is linked with through a common shaft. Under the throttle valve 22, a common communication passage 29 is formed which extends in the longitudinal direction of the engine body, and the communication passage 29 is allowed to communicate to each intak port 5b through a communication branched passage 30b, and the top end of the communication passage 30b" is opened in the tangential direction in the vicinity of an intake valve 3b. An opening part 31b is arranged which opens directly to the intake port 5b from the midway of the communication branched passage 30b. The variation of pressure in a port is transmitted by gushing out the mixed gas into other port through the branched passage and the opening part.
