The utility model is for the existence of the aqueous water in inlet manifold, only in inlet manifold built-in first
Passage is as first passage, in the situation not increasing engine component cost and air inlet manifold mold cost
Under.The problem that the damage of engine and air throttle cannot be opened can be prevented because of icing.And flexible arrangement,
Save engine arrangement space.
The degree of depth of described groove is not less than 2cm.Ensure water accumulating volume.
The bottom of described groove is an inclined plane, and the water conservancy diversion direction of described inclined plane is downward, described inclined plane
It is not less than 5 ° with the angle of horizontal plane.
It is easy to the water conservancy diversion of water.The water conservancy diversion direction of inclined plane refers to downwards aqueous water along inclined plane to dirty,
The airflow direction of the first path tilts upward flowing along inclined plane.The water conservancy diversion direction of inclined plane leads to first
The airflow direction in road is contrary.
Described inlet manifold is provided with at least three branch line with air inlet UNICOM, described branch line with
Cylinder UNICOM；
Described first passage is positioned between described branch line and described air inlet.
Prevent steam from entering branch line.
Described inlet manifold is provided with a pressure stabilizing cavity, and described pressure stabilizing cavity is positioned at described branch line and described air intake
Between Kou, the side of described pressure stabilizing cavity is provided with described first passage, and described first passage be positioned at described surely
Between pressure chamber and described air inlet.
Described first passage is provided with a gas outlet, and described gas outlet is positioned on the sidewall of described pressure stabilizing cavity.
Being provided with a liquid level sensor in described first passage, described liquid level sensor is a liquid level wireless sensing
Device.
In being easy to first passage be detected, the moisture liquid level as collected is excessive, is wirelessly transmitted to other
Equipment.
