Abstract

PURPOSE:To easily and reliably provide an ideal air-fuel ratio employed when in supercharging condition, by installing an air control valve, regulating the amount of the air to a fuel ratio depending on the supercharging condition created by a turbocharger, between an air introducing passage and a surge tank. CONSTITUTION:When in supercharging condition created by a turbocharger, atmospheric pressure within a surge tank 3 is increased, and the increased atmospheric pressure is exerted on a chamber 6a of an air control valve 6 through a passage 12. As a result, a flexible film member 9 compresses a spring 7 to raise a valve member 8, resulting in releasing the valve member from adhesion to a seat plate 10. As a result, the air passing through an air filter 11 flows to an air introducing passage 4 side through chambers 6c, 6b are a passage 13, and further flows to a venturi part 1a. This properly adjusts unbalance of the ratio of the fuel to the air, and provides an ideal air-fuel ratio depending upon and matching supercharging condition created by the turbocharger.

、効率よく、出力性能の向上に寄与する。As a result, the valve member 8 rises due to the action of the flexible membrane member.
The closed state of the valve seat plate 10 transitions to an open state. Therefore, the insufficient air passes through the air filter 12 into the chamber 6c.
, 6b, and the air introduction passage 4 through the passage 13. Flow to the side6.
7. Reaching the "moon" part.Thus, as mentioned above. A/, F
This properly corrects the unbalance of the engine and achieves an ideal fuel efficiency ratio that matches the state of supercharging caused by the turbo, contributing to efficient improvements in output performance.
