Abstract
PURPOSE: To reduce the peak of suction vacuum of an engine and to obtain sufficient secondary air amount by mounting a valve box at one side of a suction chamber between a carburetor and an air cleaner and connecting the valve chamber of the valve box to the secondary air hole provided at an exhaust gas passage via a pipe.
CONSTITUTION: A suction chamber 5 having an adequate volume is interposed between a carburetor and an air cleaner 4, a notch is formed at the lower side of the chamber 5, and a valve box 7 in which a plurality of valve chambers 8 are formed is mounted at each cylinder. A valve plate 9 on which a lead valve 10 is mounted is secured to the top of the valve box 7 in front of each valve chamber 8. Each valve chamber 8 of the valve box 7 is communicated with a secondary air hole 12 opened at the exhaust passage 11 via a pipe 14. Thus, the vacuum of the suction air abruptlly sucked alternately by the respective cylinders can be controlled to reduce the peak of the vacuum, and a large quantity of secondary can be secured without being interfered with other exhaust gas passage 11.
