The air inlet of the air filter 2 is communicated with the air outlet end of the first air inlet dirty pipe 3, the air outlet of the air filter 2 is communicated with the air inlet end of the air inlet clean pipe 1, and the air outlet end of the air inlet clean pipe 1 is communicated with an air inlet manifold of an engine. The air inlet end of the first air inlet dirty pipe 3 is communicated with the air outlet of the three-way control cavity 6, the first air inlet of the three-way control cavity 6 is communicated with the second air inlet dirty pipe 4, and the second air inlet of the three-way control cavity 6 is communicated with the third air inlet dirty pipe 5. The length of the second air inlet dirty pipe is smaller than that of the third air inlet dirty pipe. And the three-way control cavity controls the second air inlet dirty pipe or the third air inlet dirty pipe to be communicated with the first air inlet dirty pipe according to a working condition instruction of an engine controller.
Specifically, a second air inlet dirty pipe and a third air inlet dirty pipe which are different in length are arranged and connected with an air inlet of the three-way control cavity, and an air outlet of the three-way control cavity is connected with the first air inlet dirty pipe. The three-way control cavity is used for controlling the connection or disconnection of the second air inlet dirty pipe and/or the third air inlet dirty pipe and the first air inlet dirty pipe. When the engine needs different air input, the second air inlet dirty pipe and the third air inlet dirty pipe are switched through the tee joint control cavity to adjust the length of the air inlet dirty pipe, and then the air inlet efficiency and the air input of the engine are adjusted, so that the flexibility of adjusting the air input can be increased, and the comfort of using an automobile is improved.
As shown in fig. 1, the three-way control chamber 6 includes: chamber, valve 61 and control motor 62. The cavity is provided with two air outlets and one air inlet, a valve 61 is arranged in the cavity, and the valve 61 is used for controlling the intercommunication or the partition of three communicating ports of the cavity.

Furthermore, the cavity is of a square structure, and two air outlets of the cavity are vertically arranged adjacent to each other and are respectively connected with the second air inlet dirty pipe and the third air inlet dirty pipe.
As shown in fig. 1 to fig. 3, one valve 61 is arranged at a middle line of an included angle between two air outlets of the cavity, the second dirty air inlet pipe 4 and the first dirty air inlet pipe 3 are blocked when the valve 61 is in a first position, the third dirty air inlet pipe 5 and the first dirty air inlet pipe 3 are blocked when the valve 61 is in a second position, and both the second dirty air inlet pipe 4 and the third dirty air inlet pipe 5 are communicated with the first dirty air inlet pipe 1 when the valve 61 is in a third position.
Further, the air outlet and the air inlet of the cavity both adopt clamping structures. In practical application, in order to better connect the air inlet pipe, a quick clamping structure can be adopted, so that the air pipe and the cavity can be quickly connected.

In practical applications, when the engine is idling or below a certain vehicle speed, the required air intake amount of the engine is small, and the air intake pipeline is long for the air intake silencing problem of the engine, so the control motor 62 controls the valve 61 to close the second air intake dirty pipe 4, so that the intake air enters the air filter 2 from the third air intake dirty pipe 5 through the first air intake dirty pipe 3, and is delivered to the engine through the intake clean pipe 1. When the vehicle speed exceeds a certain vehicle speed, the air inflow required by the engine is increased, a large amount of air is required, the combustion of fuel of the engine is supported as much as possible, the air resistance in the air inlet pipeline is required to be greatly reduced, and the time of the air reaching the engine is shortened, so that the air inlet pipeline is required to be as short as possible under the condition of not influencing the air inlet silencing function; when the vehicle speed exceeds a certain vehicle speed, the motor 62 is controlled to act to drive the valve 61 to close the third air inlet dirty pipe 5, so that air enters the air filter 2 from the second air inlet dirty pipe 4 through the first air inlet dirty pipe 3, and then is sent to the engine through the air inlet clean pipe 1 for combustion of the engine.
The system further comprises: an air volume sensor (not shown in the figure); the air quantity sensor is in signal connection with the engine controller, and is arranged in an engine air inlet manifold and used for detecting the air inflow of the engine.
Further, the engine controller controls the position of the valve according to the air inlet quantity of the engine, so that the air inlet quantity of the engine is adaptive to the working condition requirement.
The invention provides an adjustable engine air inlet system, which adopts a three-way control cavity to be respectively connected with a first air inlet dirty pipe, a second air inlet dirty pipe and a third air inlet dirty pipe which have different lengths, and adjusts the length of an air inlet pipe through the three-way control cavity so as to adjust the air inlet amount of an engine. The problem of current car air intake length and air input can not adjust, easily cause the interior too big noise of car is solved, can increase the flexibility that the air input was adjusted, improve the travelling comfort that the car used.
