Intake manifold accumulated water leading-out structure and method and control system

The invention provides an intake manifold accumulated water leading-out structure and method and a control system.The intake manifold accumulated water leading-out structure comprises a water draining device and a first water level sensor, and the first water level sensor is arranged in a pressure stabilizing cavity of an intake manifold and used for detecting the water level of an accumulated water area in the pressure stabilizing cavity; when the water level of the water accumulation area in the pressure stabilizing cavity is larger than or equal to the set water level of the pressure stabilizing cavity, accumulated water in the water accumulation area in the pressure stabilizing cavity is guided out of the pressure stabilizing cavity through the water drainage device. According to the method, the probability of unstable idle speed and abnormal starting of the engine can be reduced. 本发明提供一种进气歧管积水导出结构、方法及控制系统，包括泄水装置和第一水位传感器，所述第一水位传感器设于进气歧管的稳压腔内，用于检测稳压腔内积水区域的水位，所述泄水装置在稳压腔内积水区域的水位大于或等于设定稳压腔水位时，将稳压腔内积水区域的积水导出稳压
