Description
본 발명은 엔진에의 흡기소음을 저감시키는 구조의 흡기장치에 관한 것이다.The present invention relates to an intake apparatus having a structure for reducing intake noise into an engine.
종래 엔진에의 흡기장치는 도 2에 도시한 것과같이 대기에 접한 흡입관로인 에어덕트(1)와 이물질을 거르기 위한 에어크리너(2) 및 흡기호스(3)와로 구성되어 외부공기를 엔진(4)으로 도입하게 된다.The air intake apparatus for a conventional engine is composed of an air duct (1), which is a suction pipe path in contact with the atmosphere, and an air cleaner (2) and an intake hose (3) for filtering foreign matter, as shown in FIG. Will be introduced.
그러나 상기한 구조는 흡기시 발생되는 소음을 에어크리너(2)에 부착된 레조네이터(6)에서 감소시키도록 하고 있으나 엔진의 고속주행시 및 어떤 특정회전수 구간에서의 엔진 부밍(Booming)시 많은 공기가 에어크리너(2)로 유입될 때에는 에어크리너에 부설된 레조네이터(6)만으로서는 소음제거가 불가능하다는 문제점이 지적되고 있다.However, the above structure reduces noise generated during intake in the resonator 6 attached to the air cleaner 2, but a lot of air is generated during high speed driving of the engine and during engine booming at a certain speed range. It has been pointed out that when the air cleaner 2 is introduced into the air cleaner 2, noise removal is impossible only with the resonator 6 attached to the air cleaner.
이에 본 발명은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는바는 엔진소음이 심한 운전영역에서 외부로부터 도입되는 공기가 에어크리너에 도달하기전에 공조실로 우회시켜 공급하도록 하므로써 소음을 완전제거하고 공기량을 조정할 수 있는 흡기장치를 제공하는데 있다.Therefore, the present invention has been proposed in view of the above problems, and its purpose is to completely remove noise by supplying air introduced from the outside in an operating area with high engine noise to the air conditioning chamber before reaching the air cleaner. It is to provide an intake apparatus that can adjust the amount of air.

이하 본 발명의 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
도 1은 본 발명에 의한 흡기장치의 일실시예를 나타내는 도면으로1 is a view showing an embodiment of an intake apparatus according to the present invention
도면중 부호 1은 외부공기를 도입하는 에어덕트이며 부호 2는 상기 에어덕트(1)에 접속되어 도입되는 공기에 포함된 불순물을 거르는 에어크리너(2)이며 에어크리너(2)를 통과한 흡기는 흡기호스(3)를 거쳐 엔진(1)의 연소실에 공급된다.In the drawing, reference numeral 1 denotes an air duct for introducing external air, reference numeral 2 denotes an air cleaner 2 for filtering impurities contained in the air introduced and connected to the air duct 1, and an intake air passing through the air cleaner 2 It is supplied to the combustion chamber of the engine 1 via the intake hose 3.
상기 에어덕트(1)의 도중에는 제1우회관로(5)가 분기접속되어 있으며 제1우회관로(5)에는 유동중인 공기의 소음을 제거하는 공조실(6)이 마련되어 있으며 상기 공조실(6)을 통과한 공기는 제2우회관로(7)를 통해 에어크리너(2)로 인입되어진다.In the middle of the air duct 1, the first bypass pipe 5 is branched, and the first bypass pipe 5 is provided with an air conditioning chamber 6 for removing noise of the air flowing therein, and the air conditioning chamber 6 is provided. The air passing through the air is introduced into the air cleaner 2 through the second bypass pipe 7.
상기 에어덕트(1)와 제1우회관로(5)의 분기접속지점에는 공기의 흐름을 변경유도하기 위한 절환밸브(8)가 설치되어 있으며 상기 절환밸브(8)는 전자제어장치(9)의 제어에 따라 회전작동하여 흡기관로의 공기흐름 방향을 절환하게 된다.At the branch connection point of the air duct 1 and the first bypass pipe 5, a switching valve 8 is installed to induce the flow of air, and the switching valve 8 is an electronic control device 9. Rotation operation is controlled according to the control of the air flow to the intake pipe.
상기와 같은 본원 발명은 엔진의 소음이 발생하지 않는 정상운전 영역에서는 전자제어장치(9)가 절환밸브(8)를 수직으로 유지(도시상태 기준)하도록 제어(예를들면 전원공급 오프시 절환밸브가 수직상태)하여 에어덕트(1)로 유입되는 공기는 관성에 의해 직선으로 유동하여 에어크리너(2)로 직접들어가 분진등의 이물질을 제거한 후 엔진(4)에로 공급되며 엔진의 고속주행 및 엔진 부밍에 따른 소음이 심한 특정 회전수(r.p.m)구간의 운전시에는 전자제어장치(9)는 모우터(10)를 구동하여 절환밸브(8)를 회전시켜 에어크리너(2)측 관로를 차단하고 도입되는 모든 공기가 제1우회관로(5)를 통해 우회시켜 공조실(6)로 보낸다. 공조실(6)로 들어온 공기는 소음이 제거된 후 제2우회관로(7)를 통해 에어크리너(2)로 들어가 오염물이 제거된 뒤 엔진(4)에 공급되는 것이다.In the present invention as described above, in the normal operation region in which the engine noise is not generated, the electronic controller 9 controls the switching valve 8 to be maintained vertically (based on the state of the city) (for example, a switching valve when the power supply is turned off). Air flows into the air duct 1 in a straight line by inertia, enters the air cleaner 2 directly, removes foreign substances such as dust, and supplies it to the engine 4. During operation of a certain speed (rpm) section with high noise due to the booming, the electronic controller 9 drives the motor 10 to rotate the switching valve 8 to block the air cleaner 2 side pipe. All the air introduced is diverted through the first bypass pipe 5 to the air conditioning chamber 6. The air entering the air conditioning chamber 6 enters the air cleaner 2 through the second bypass pipe 7 after the noise is removed and is supplied to the engine 4 after the contaminants are removed.
다시 엔진소음발생의 회전수 영역으로부터 정상운전 영역으로 운전조건이 변경되면 전자제어장치(9)는 모우터(10)를 역전구동하여 절환밸브(8)를 수직상태로 되돌리게 된다.When the operation condition is changed from the rotational speed range of the engine noise generation to the normal operation range again, the electronic controller 9 reversely drives the motor 10 to return the switching valve 8 to the vertical state.
여기서 절환밸브(8)를 모우터에 의해 작동시키는 것으로 설명하였으나 솔레노이드 작동수단을 이용하여 전원 온1Q오프에 의해 간단하게 작동할 수도 있음은 물론이다.Here, the switching valve 8 is described as being operated by a motor, but it can be easily operated by turning on the power 1Q off using the solenoid operating means.
이상과 같은 본원 발명의 흡기장치에 의하면 엔진의 소음이 심한 특정회전수 구간에서는 에어덕트를 통해 유입되는 외기를 직접 에어크리너로 유입시키지 아니하고 공조실로 우회시켜 흡기소음을 제거한 후 에어크리너로 유입시키기 때문에 특정 rpm 구간의 고속주행시 흡기소음을 감소시키게 되는 효과가 있게된다.According to the intake apparatus of the present invention as described above because in the specific speed section of the engine noise is high, the outside air introduced through the air duct does not directly into the air cleaner, but bypasses the air conditioning chamber to remove the intake noise and then flows into the air cleaner. It is effective to reduce the intake noise during high-speed driving in a certain rpm section.
또한 이론공연비에 따라 전자제어장치에서 절환밸브의 개폐각도를 조정할 수 있어 적정량의 공기량 제어가 가능하여 엔진출력을 향상시키는 효과가 있다.In addition, according to the theoretical performance ratio, the opening and closing angle of the switching valve can be adjusted in the electronic control device, so that an appropriate amount of air volume can be controlled, thereby improving the engine output.
