とを特徴とする内燃機関の減速対策装置。a passage communicating between the air cleaner and the intake manifold;
A valve body for opening and closing the passage is provided, the valve body is connected to a diaphragm, and the negative pressure chamber into which intake manifold negative pressure is introduced to both sides of the diaphragm is communicated with the negative pressure chamber via an orifice. In a deceleration countermeasure device for an internal combustion engine, which is provided with an air chamber, a passage is provided separately from the orifice to communicate the negative pressure chamber and the air chamber, and engine operating conditions such as engine speed or load are provided in the middle of this passage. 1. A deceleration countermeasure device for an internal combustion engine, comprising an on-off valve that opens and closes depending on the engine speed and introduces atmospheric air into the passage at low rotation speeds or low loads.
