A kind of intake duct assembly and intake mechanism for automobile

Abstract

The application discloses an air intake port assembly for an automobile and an air intake mechanism, which belong to the technical field of the air intake system of a motor vehicle. The intake port assembly for automobiles includes an intake port housing, the side wall of the intake port case is provided with a first air inlet, the bottom wall of the intake port case is provided with an air outlet, and the intake port case forms an intake cavity , a first separation plate and a separation grille are arranged in the air inlet cavity, the first separation plate is bent inward from the bottom of the air inlet and extends upward, and the top of the first separation partition and the inner wall of the air inlet shell form a second air inlet , the separation grille is inclined inward from the top of the air inlet and extends downward, the separation grille is arranged on the outside of the second air inlet, and the bottom end of the separation grille is not higher than the top of the first separation partition. The automobile air intake assembly of the present application has high filtration and impurity removal efficiency, small wind resistance, low energy consumption, and low noise; the air intake assembly of the air intake mechanism and the air filter do not need to be connected by a bellows, and the preparation cost low, and tight assembly tolerances.

Description

technical field [0001] The application relates to an air inlet assembly and an air intake mechanism for automobiles, belonging to the technical field of air intake systems of motor vehicles. Background technique [0002] The car needs air to continuously enter the engine during driving. In order to prevent sand and dust from entering the engine, the air intake system of the car includes a high air intake pipe, which is connected to the air filter through a bellows rubber tube. The air filter is installed on the front of the car through The rubber pipe is connected with the engine. The air entering the engine generally enters the high intake pipe first, then enters the air filter through the corrugated rubber tube, and then enters the engine after being filtered by the air filter. [0003] As an important part of the intake system, the high-position intake pipe plays the role of dust and water removal, which is equivalent to the primary filter in the intake system. The high...

Problems solved by technology

The high-position air intake pipe in the prior art is not effective in filtering dust and rainwater or the wind resistance is too large. Moisture enters the air filter, which will cause the filter paper in the air filter to fail. Once the filter paper of the air filter is attached by rainwater, the filter paper will lose its filtration As a result, the resistance of the airflow will be increased, which will affect the intake air volume of the entire intake system, resulting in insufficient engine power, resulting in a reduction in the service life of the air filter, and thus affecting the service life of the engine.

If the air filter fails, rainwater will enter the engine through the rubber pipe, causing water to enter the engine and causing damage to the engine

[0004] When the engine of a heavy truck is running, it inhales about 20m per minute 3 -30m 3 The air, now with the development of the truck to the high-speed and heavy-duty direction, the air intake flow reaches 25m 3 / min and above heavy-duty trucks, the pre-filter device in the prior art or its simple combination can no longer meet the requirements of use

[0005] With the upgrading of light-duty vehicle National V vehicle technology, higher requirements are placed on the air intake system. The existing air intake assembly cannot meet the requirements of key performance indicators such as dust removal efficiency, water removal efficiency, and air intake resistance. Increased requirements
