る内燃機関の吸気装置。 Detecting engine load in an intake system for an internal combustion engine that includes a main intake passage formed downstream of an intake throttle valve, a throttle valve interposed in the main intake passage, and an auxiliary intake passage that bypasses the throttle valve. load detection means for
The throttle valve is fully closed during low load operation based on the detection signals from the rotation speed detection means for detecting the engine rotation speed, the load detection means and the rotation speed detection means, and the throttle valve is closed in the main intake passage during high speed and high load operation. The throttle valve is fully opened so that it is approximately parallel to the flow line of the throttle valve, and when the throttle valve is fully closed during low-speed, high-load operation, the throttle valve surface facing the main intake passage downstream of the throttle valve faces the main intake passage upstream of the throttle valve. An intake device for an internal combustion engine, comprising: a throttle valve driving means that opens the valve at an angle with respect to a streamline of an intake passage.
