Resonator
The present invention relates to an intake apparatus of an engine, and more particularly, to a resonator mounted between an air cleaner and a surge tank.
In general, the engine rotates the crankshaft through a connecting rod connected to the piston to explode the force generated by burning fuel in a combustion chamber formed between the cylinder and the cylinder head and the piston reciprocating within the cylinder, thereby converting thermal energy into mechanical rotational force. To convert.
The engine has an intake device for sucking the air required in the combustion chamber, the intake device is fixed to one side of the engine room as shown in Figure 1 is an air cleaner to filter the impurities by sucking the outside air ( 51, a surge tank 52 connected to the air cleaner 51, and an intake manifold 53 connected to the surge tank 52 to uniformly distribute air to the engine. have.
Of course, a throttle body (not shown) is provided between the air cleaner 51 and the surge tank 52 to adjust the amount of air flowing into the combustion chamber.
Here, the intake device is to suck the outside air by the suction force according to the rotation of the piston of the engine bar, because the intake air is sucked at a very high pressure, causing noise in the intake device.
In addition, the vibration of the engine, that is, the vibration according to the piston reciprocating motion and the vibration according to the operation of the intake and exhaust valves are transmitted to the intake apparatus, and a resonance phenomenon occurs at a predetermined frequency, and noise is generated.
Therefore, the engine is provided with a resonance preventing device for preventing the above-mentioned resonance phenomenon, which is provided with a resonator 55 in the intake pipe 54 to absorb the resonance as described above. .
By the way, the resonator 55 as described above has a frequency band of the noise that can be absorbed in accordance with the volume itself has a plurality of resonators having different volumes in order to be able to absorb a wider range of noise You need to install
However, the engine room in which the resonator is installed as described above is full of other components and it is very difficult to secure the installation space, and there is a problem in that even if a plurality of resonators are installed, the required cost is high.
Accordingly, an object of the present invention is to provide a resonator capable of absorbing noises of various frequency bands without taking up a space in an engine room.
1 is a structural diagram of a general engine intake system,
2 is a structural diagram of a resonator according to the present invention;
Explanation of symbols for main parts of the drawings
1: intake vent 2: case
3: bulkhead 4: permanent magnet
5: electromagnet 6: spring
7: generator
Resonator according to the present invention for achieving the above object is composed of a case connected through the inlet pipe and the inlet, a partition wall formed to be movable inside the case opposite the inlet, and the partition moving means for horizontally moving the partition wall It is characterized by.
Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
Figure 2 shows a resonator according to the present invention, the partition 2 formed through the intake pipe 54 and the inlet 1 connected to the case 2, the partition wall formed to be flowable inside the case 2 opposite the inlet 1 (3), and the partition moving means which horizontally moves the said partition 3 is comprised.
The partition moving means is mounted on the case 2 so as to face the permanent magnet 4 mounted on the partition 3 and the permanent magnet 4, and the magnetic field increases when the rotation speed of the engine E increases. It consists of an electromagnet 5 for pushing the partition 3 together with the permanent magnet 4 and a spring 6 for providing a tension force between the partition 3 and the case 2.
The permanent magnet 4 and the electromagnet 5 are to face the same poles, the current flowing in the electromagnet 5 is to be supplied from the generator 7, the generator 7 is the engine (E) When the rotational speed (RPM) of) increases, a high current is supplied to the electromagnet 5, and when the rotational speed of the engine E is reduced, a low current is supplied to the electromagnet 5.
Referring to the operation of the present invention configured as described above are as follows.
As the rotation speed RPM of the engine E increases, the frequency of the noise generated in the engine room increases, and when the intensity of the current output from the generator 7 increases, the magnetic field of the electromagnet 5 increases.
At this time, since the electromagnets 5 and the permanent magnets 4 face the same poles, when the magnetic field of the electromagnet 5 increases, the partition 3 is pushed out together with the permanent magnets 4 so that The volume is reduced. That is, the noise of the high frequency is resonated and canceled in the resonator of which the volume is reduced.
In addition, if the frequency of the noise generated in the engine room is reduced due to the reduction of the RPM of the engine E, the intensity of the current output from the generator 7 is weakened, and the magnetic field of the electromagnet 5 is lowered. .
When the magnetic field of the electromagnet 5 is lowered, the repulsive force acting between the electromagnet 5 and the permanent magnet 4 is weakened, and the tensile force of the spring 6 acts between the electromagnet 5 and the permanent magnet 4. As the partition 3 is pulled inward, the volume of the resonator is increased.
That is, the noise generated in the engine room is resonated and canceled in the resonator with the increased volume as described above.
Therefore, since the volume of the resonator is changed according to the engine speed (RPM) as described above, there is an effect that can effectively absorb the noise of various frequency bands without separately mounting a plurality of resonators according to the frequency of the noise.
