Abstract
PURPOSE: To increase the combustion efficiency by allowing the intake ports on the down stream of the throttle valve of a multicylinder engine to communicate to each other through a communication passage and a branched passage and reducing the area of the branched passage according to the perfect opening of the throttle valve and gushing out the mixed gas from the branched passage even in high loading.
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 valve of each cylinder is linked with through a common shaft. The throttle valve 22 is axially supported at the lower part of the passage 11, and in the lower part of the throttle valve 22, a common communication passage 29 is formed which extends in the longitudinal direction of the engine, and further in the lower part of the passage 11, a branched passage 30b is opened which communicates to the passage 29. Further, in the upper part of the port 5b, a partition plate 34 is arranged, and mixed gas is introduced from upper the partition plate 34 in low loading (throttle valve is shown by the solid line), and the mixed gas from other cylinder is gushed out through the branched passage 30b in high loading (throttle valve is at the chain line position), and the whole mixed gas is formed in swirling form.
