Abstract
A multicylinder engine intake system includes: first and second throttle bodies; bypasses provided in the first and second throttle bodies and having downstream ends opened to intake paths on downstream sides of throttle valves; and a common bypass control valve which opens and closes the bypasses. The bypass control valve is mounted on the first throttle body. Downstream ends of the bypasses opened in the first and second throttle bodies are formed as throttle holes. The diameter of the throttle hole on the side of the first throttle body is smaller than the diameter of the throttle hole on the second throttle body. Thus, it is possible to equalize amounts of first idling air supplied to a plurality of cylinders irrespective of arrangement of the cylinders in an engine even if lengths of a plurality of bypass downstream paths are not equal to each other, while the bypass control valve is mounted on any of the throttle bodies.
