徴とするエンジンの吸気装置。The intake passage is divided into a first intake passage and a second intake passage, a first throttle valve is provided in the first intake passage, and the first throttle valve is opened to a predetermined opening degree in the second intake passage. A second throttle valve is provided that starts opening from a point in time, and when the engine is cold, an appropriate valve opening mechanism is used to open the first throttle valve by a predetermined amount larger than the idling opening when the engine is warm. In the engine, the throttle lever is rotatably fitted loosely into the rotation shaft of the first throttle valve and is interlocked with a speed regulating operation member such as an accelerator pedal, and the throttle lever is fixed to the rotation shaft of the first throttle valve. a first retaining member that engages with the throttle lever when the first throttle valve is rotated in the opening direction of the first throttle valve; and a first retaining member that engages with the throttle lever when the first throttle valve is at a predetermined opening degree or more. Said second
The throttle valve is provided with a second engaging member that opens the throttle valve, and is configured such that when the valve opening mechanism is operated, the second throttle valve is not opened and only the first throttle valve is opened. An engine intake system featuring:
