Description

Multi function air cleaner in vehicle

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multifunctional air cleaner for a vehicle, and more particularly, to a multifunctional air cleaner for a vehicle capable of reducing the manufacturing cost and the weight of an intake system by using a washer fluid storage and a resonator function.

In general, an engine rotates a crankshaft through a connecting rod connected to the piston to explode the force generated by burning fuel in a combustion chamber formed between a cylinder and a cylinder head and a piston reciprocating in the cylinder, thereby rotating mechanical energy. To convert.

Such an engine has an intake system for inhaling air required by the combustion chamber, and the intake system is fixed and installed at one side of the engine room as shown in FIG. 1 to suck external air to filter out impurities. It consists of the cleaner A and the intake manifold 3 which distributes air uniformly to an engine through the surge tank provided on the intake pipe 1 connected to this air cleaner A. As shown in FIG.

Here, of course, a throttle body is installed between the air cleaner A and the surge tank to adjust the amount of air introduced into the combustion chamber.

However, such an intake system sucks the outside air by the suction force according to the rotation of the piston of the engine, so it is sucked at a very high pressure, thereby causing noise in the intake system. Vibration according to the operation of the intake / exhaust valve is transmitted to generate a resonance phenomenon at a predetermined frequency, as well as noise.

Accordingly, as shown in FIG. 1, a resonator 2 is installed in the intake pipe 1 to prevent the resonance phenomenon as described above.

However, such a resonator (2) has a frequency band of noise that can be absorbed according to its own volume, so the limit to install a plurality of different volume of the resonator to be able to absorb a wider range of noise In order to prevent a large area of noise and resonance generated in the intake system, a plurality of resonators are installed. However, an engine room in which a plurality of resonators is installed is full of other components, so the installation It is very difficult to secure space, and even if a plurality of resonators are installed, there is a problem in that the cost is high.

Accordingly, the present invention has been invented in view of the above, and provides a resonator function to the air cleaner which fresh air is introduced from the outside, and also stores the wiper washer fluid together to prevent resonance and noise of the intake system, as well as washer fluid. The purpose is to make the engine room more spacious by removing the storage device.

The present invention for achieving the above object, the air cleaner provided at the front end portion of the intake pipe connected to the intake manifold to distribute the air evenly to the engine and the lower housing for receiving the washer fluid, while being coupled to the lower housing It consists of an upper housing which functions as a resonator, an expansion pipe coupled to the inlet pipe which is introduced into the housing while introducing fresh air from the outside, and a discharge pipe inserted into the housing and having one end connected to the expansion pipe and the other end connected to the intake pipe. It features.
