Description
본 고안은 자동차 엔진 흡기 소음 저감장치에 관한 것으로서, 더욱 상세하게는 공기 흡입덕트에 댐퍼 볼륨을 형성함으로서, 엔진으로부터 공기 흡입장치를 통해 외부로 취출되는 전 레벨의 소음을 직접 감쇄시킬 수 있는 엔진의 흡입 공기 소음 저감장치에 관한 것이다.The present invention relates to an intake noise reduction device for an automobile engine, and more particularly, by forming a damper volume in an air intake duct, an engine capable of directly attenuating all levels of noise blown out through the air intake device from the engine to the outside. It relates to an intake air noise reduction device.
일반적으로 자동차의 엔진(engine)은 연소실로 흡입되는 연료와 공기의 혼합기를 압축, 점화, 폭발함에 따라 발생되는 피스톤의 왕복운동을 회전운동으로 변환시키는 장치를 말하며, 그 엔진에서 출력되는 회전운동을 구동륜에 전달함으로서 자동차의 추진력을 발생하게 되는 것이다.In general, an engine of a vehicle refers to a device that converts a reciprocating motion of a piston generated by compression, ignition, and explosion into a rotational motion by mixing a mixture of fuel and air sucked into a combustion chamber, and converts the rotational motion output from the engine. The propulsion force of the vehicle is generated by transmitting the driving wheels.
엔진의 연소실로 흡입된 혼합기는 연소함에 따라 상당한 소음을 발생하게 되는데, 이때 발생된 소음은 공기흡입장치를 통해 외부로 배출되었다.The mixer sucked into the combustion chamber of the engine generates considerable noise as it is burned, and the generated noise is discharged to the outside through the air intake device.
이에 따라, 엔진내로부터 공기 흡입장치를 통해 회부로 취출되는 소음을 저감시키는 장치가 종래 고안되었다.Accordingly, a device has been conventionally devised to reduce the noise blown out from the engine through the air suction device.
종래 엔진의 흡입공기 소음저감장치는 도 1에 도시되는 바와 같이, 외부로부터의 공기를 공기 청정기(105)로 공급하는 공기 흡입덕트(110)의 일측에 레저네이터(resonator; 120)가 연통되게 설치되어 있어, 엔진(101)내로부터 공기 흡입장치 즉, 흡기 매니폴드(102), 서지탱크(103), 스로틀보디(104), 공기 청정기(105)를 통해 공기 흡입덕트(110)측으로 취출되는 소음의 레벨을 레저네이터(120)에서 특정 주파수의 공명을 이용하여 저감시키게 되었다.As shown in FIG. 1, a conventional intake air noise reduction device of an engine is installed such that a resonator 120 is connected to one side of an air intake duct 110 that supplies air from the outside to the air cleaner 105. Noise that is blown out from the engine 101 to the air intake duct 110 through the air intake device, that is, through the intake manifold 102, the surge tank 103, the throttle body 104, and the air cleaner 105. The level of is reduced by using the resonance of a specific frequency in the resonator 120.
그러나, 종래 엔진의 흡입 공기 소음 저감장치는 레저네이터(120)를 통해 소음 레벨에 따라 선별적, 간접적으로 일부 레벨의 소음만을 감소시키게 됨으로서, 전 레벨의 소음을 감쇄시키지 못했다.However, the conventional intake air noise reduction device of the engine reduces only a partial level of noise selectively and indirectly according to the noise level through the resonator 120, thereby failing to attenuate the noise of all levels.
따라서, 본 고안은 상기와 같은 종래의 문제점을 감안하여 안출된 것으로서, 엔진으로부터 공기 흡입장치를 통해 외부로 취출되는 전 레벨의 소음을 직접적으로 원활히 감쇄시킬 수 있도록 하는 엔진의 흡기 소음 저감장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described conventional problems, and provides an intake noise reduction device of an engine that can directly and smoothly attenuate all levels of noise blown out from the engine through an air intake device. Its purpose is to.
상기와 같은 목적을 달성하기 위한 본 고안은, 엔진 공기 흡입장치의 공기 흡입덕트의 중단부에 댐퍼 볼륨이 직접적으로 연통되게 형성되는 것을 특징으로 하는 엔진의 흡기 소음 저감장치를 제공한다.The present invention for achieving the above object, there is provided an intake noise reduction device of the engine, characterized in that the damper volume is formed in direct communication with the stop portion of the air intake duct of the engine air intake device.

The damper volume 20 formed in the air intake duct 10 is attenuated by a sudden volume change, that is, a pressure drop due to sudden cross-sectional expansion.
이에 따라, 본 고안은 댐퍼 볼륨(20)을 통해 단면적 체적을 변화시키는 직접적인 소음 레벨 감쇄방식으로서, 레저네이터를 통해 간접적으로 일부 레벨의 소음을 감쇄시키는 종래의 방식에 비해 전 소음 레벨을 원활히 감쇄시킬 수 있다.Accordingly, the present invention is a direct noise level attenuation method that changes the cross-sectional volume through the damper volume 20, and smoothly attenuates the entire noise level compared to the conventional method of attenuating some level of noise indirectly through the resonator.
