Abstract

The invention relates to an air inlet channel assembly. The air inlet channel assembly is characterized by comprising an air inlet channel body, an air inlet grille and at east one flow guide piece; the air inlet channel body comprises an air inlet and an air outlet; the air inlet grille is arranged at the air inlet; the at least one flow guide piece is arranged in the air inlet channel body and is constructed to be capable of dividing the interior of the air inlet channel body into at least two independent air inlet flow channels; the air inlet end of each air inlet flow channel communicates with the air inlet, and the air outlet end of each air inlet flow channel communicates with the air outlet; each flow guide piece is at least located on a flowing path of airflow flowing in from the air inlet end of the air inlet flow channel where the flow guide piece is located; a water draining opening is further arranged in the air inlet channel body, and the air inlet channel assembly further comprises a drainage piece; and the drainage piece communicates between the air outlet ends of the multiple air inlet flow channels and the water draining opening and located in the gravity direction of water in airflow in the multiple air inlet flow channels. According to the air inlet channel assembly, the contact probability of water in airflow and the wall faces of the flow guide pieces is increased through the flow guide pieces, and the water is drained to the water draining opening through the drainage piece to be drained. Therefore, the water removal efficiency of the air inlet channel assembly is improved.

Description

technical field

[0001] The present application relates to the technical field of the intake system of an internal combustion engine, in particular to an intake port assembly. Background technique

[0002] As an important part of the intake system of the internal combustion engine, the intake port assembly is the primary filter in the intake system, which is mainly used to separate gas and water from the gas entering the engine, so as to provide dry air to the engine.

[0003] With the upgrading of the technology of the national five models of light vehicles, higher requirements are put forward for the air intake system. However, the air-water separation rate of the traditional air intake system is not high, which can easily lead to engine scuffing or vibration and flameout, which seriously affects the driving stability of the vehicle. Contents of the invention

[0004] Based on this, it is necessary to address the problem that the air-water separation rate of the traditio...
