Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 A dual-mode air intake system for an automobile is shown, which includes an air filter 3 and an air intake pipe 18 having an air inlet 1, the outlet end of the air intake pipe 18 communicates with the air intake cavity of the air filter 3 through a normal pipe 2, The air outlet chamber of the air filter 3 is connected with an air filter outlet pipe 4 connected with the engine. On the basis of the above, the air outlet end of the air inlet pipe 18 is also communicated with the air intake chamber of the air filter 3 through a normally closed pipe 6, and the semiactive control valve 5 is installed on the normally closed pipe 6, and the semiactive control valve 5 has The valve plate 10 that controls the cross-sectional area of ​​the airflow in the normally closed pipe 6, when the speed of the airflow entering the air inlet 1 is grea...

Abstract

The invention relates to a dual-mode air inlet system of an automobile. The dual-mode air inlet system of the automobile comprises an air filter and an air inlet pipe provided with an air inlet. The air outlet end of the air inlet pipe communicates with an air inlet cavity of the air filter through a normally-open pipe. An air outlet cavity of the air filter is connected with an air filter air outlet pipe connected with an engine. The air outlet end of the air inlet pipe further communicates with the air inlet cavity of the air filter through a normally-closed pipe. A semi-active control valve is installed on the normally-closed pipe and provided with a valve block used for controlling the circulation sectional area of airflow in the normally-closed pipe. When the speed of the airflow entering the air inlet is higher than a set value, the circulation sectional area of the airflow is increased along with the increase of the speed of the airflow till the maximum opening degree of the valve block is achieved; and when the speed of the airflow entering the air inlet is smaller than the set value, the circulation sectional area of the airflow is zero. By the adoption of the dual-mode air inlet system of the automobile, the problem of contradiction between air inlet noise lowering and power loss reducing of an existing air filter is solved.

Description

technical field [0001] The invention relates to automobile noise control technology, in particular to an automobile dual-mode air intake system. Background technique [0002] Air enters the engine cylinder through the car intake system, then mixes with fuel and burns. After burning, it releases heat energy, which is then converted into mechanical energy. The mechanical energy drives the crank connecting rod mechanism to do work, and then pushes the car forward. [0003] The car intake system is generally divided into two parts: the intake manifold system and the air filter intake system. The intake manifold system includes the intake manifold and the throttle valve; the air filter intake system includes the intake port, the air filter intake pipe, the air filter, the air filter outlet pipe and the quarter wave Muffling components such as tubes, Helmtz mufflers, etc. [0004] In the car intake system, the volume and structure of the air filter play an important role in redu...
