Description

Air Duct Air Injection Control System for Automobile Suction Machine

The present invention relates to an air injection control device for an air duct used as an intake system of an automobile. More particularly, the present invention relates to an air injection control device for an air duct, To an air duct air injection regulating device for an intake system for an automobile.

In general, as shown in FIG. 1, the intake system 9 for sucking air required for combustion in the engine is provided with an air duct 1 for guiding and moving the air, An air cleaner 2, a surge tank 3, and other air quantity sensing sensors, which are disposed around the engine.

The air duct 1 induces air introduced into the air chamber 4 and sends the air to the surge tank 3 through an air passage. The air duct 1 is connected to the air duct 1 irrespective of the high- The constant air is introduced and the length of the air flow path is not varied. Therefore, constant air is always introduced regardless of the speed of the engine, and the performance of the engine can not be improved.

In consideration of this point, there is one that is developed to adjust the length of the intake system so as to be variable according to the high speed and the low speed. However, since the structure is complicated, the operation is unstable and the safe use can not be achieved. .

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the conventional drawbacks of the air inlet device of the air duct, and it is an object of the present invention to provide a simple structure So that the use of the air duct is improved.

According to an aspect of the present invention, there is provided an air cleaner comprising: an air cleaner disposed on a pipeline of an air duct disposed around an engine of an automobile to purify air, the air cleaner installed on an end of the air duct, The air conditioner according to any one of claims 1 to 3, wherein the first air chamber is divided into a first air chamber and a second air chamber, and the second air chamber is divided into a first air chamber and a second air chamber. And a valve capable of adjusting the amount of air.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a front view of the intake system according to the present invention, and FIG. 3 is a block diagram of a main part of an air injection apparatus according to the present invention. Referring to these drawings, And an air cleaner 14 disposed around the engine 10 for generating power of the engine 10 and purifying the air on the duct of the air duct 12 to which the outside air is introduced and guided.

On the end of the air duct 12, a suction tank 40 is installed, which is equipped with a surge tank 16 for collecting purified air.

The air chamber 18 formed in the air duct 12 is partitioned into a first air chamber 18a and a second air chamber 18b by a diaphragm 20 and is disposed at a predetermined position of the divided second air chamber 18b And a valve 22 for adjusting the amount of air to be introduced.

In addition, the valve 22 is configured to be opened and closed by a cable 26 whose length is variable by adjusting the compression of the excel pedal 24.

The air duct 18 of the air duct 12 is formed by two chambers, that is, a first air duct 18a and a second air duct 18b, A valve 22 for opening and closing the inflow air is provided to adjust the inflow amount of the air in accordance with the driving state of the engine (high speed and low speed) to achieve a safe engine state.

That is, since the amount of air required varies depending on the high speed and low speed state of the engine, a small amount of air is introduced into the engine at a low speed and a large amount of air is supplied to the engine at high speed to improve engine performance. It is necessary to control the amount of air to achieve safe engine operation.

Accordingly, when the accelerator pedal 24 is pressed, the cable 26 attached to the accelerator pedal 24 is varied according to the amount of compression to be adjusted so that the valve 22, which is connected to one end of the cable 26, The second air chamber 18b is opened so that a large amount of air flows into the engine so that the required air flow is introduced into the engine in a high speed state and the valve 22 is moved to the second air chamber 18b Therefore, proper air flows in accordance with the operation state of the engine, thereby achieving the optimum engine performance.

As described above, according to the present invention, a large amount of air is introduced at high speeds and a small amount of air is introduced at low speeds to achieve an optimum engine operating state, thereby improving engine performance The improved power performance results in an economical use of the vehicle.
