<p>PURPOSE:To reduce the suction resistance by rotatably installing a surge tank around the axis line in the longitudinal direction and connecting the opening of the tank wth a suction pipe on the periphery of the tank and forming the section of the suction pipe into circular form, thus obtaining the intake inertial effect within a wide engine operation range. CONSTITUTION:The intake air introduced into a surge tank 3 through a throttle valve 6 from an air filter is inhaled into a cylinder through a suction port from an annular suction pipe 13 installed onto the periphery of the tank from a communication hole 23 formed on the outer wall of the tank. The both edges of the surge tank 3 are supported by bearings 19 and 22, and the tank 3 is turned according to the engine operation state through a gear 26 at the edge part, and the inertial supercharging in a wide engine operation range is carried-out by varying the effective length of a suction passage by varying the position of a communication port 23 for the suction passage 13. The suction resistance can be reduced by forming the section of the suction passage formed onto the outer periphery of the tank 3 into circular form.</p> |
