본 고안은 자도어차의 배기관에 장착되어 소음을 저감하는 것으로서, 특히 기관의 성능과 관련하여 효과적으로 배기소음을 줄여 주도록 하는 자동차의 가변 배기관장치에 관한 것이다.The present invention is mounted on the exhaust pipe of the magnetic door car to reduce the noise, and more particularly relates to a variable exhaust pipe device of the vehicle to effectively reduce the exhaust noise with respect to the performance of the engine.
종래 자동차의 배기관은 제1도에 도시되는 바와 같이, 기관(1)의 배기다기관(2)에 연통되게 연결되고, 중간에 소음기(3)가 장착어, 기관(1)에서 연소된 배기가스를 외부로 배출하는 것으로서, 기관(1)에서 배출되는 고온 고압의 배기가스가 배기관(4)의 내부와 소음기(3)를 통과하며 소음이 저하되고, 배기가스의 온도와 압력이 저하되게 된다.The exhaust pipe of a conventional automobile is connected in communication with the exhaust manifold 2 of the engine 1, as shown in FIG. 1, and is equipped with a silencer 3 in the middle to exhaust the exhaust gas combusted in the engine 1. By discharging to the outside, the high-temperature, high-pressure exhaust gas discharged from the engine 1 passes through the interior of the exhaust pipe 4 and the silencer 3, and noise is reduced, and the temperature and pressure of the exhaust gas are reduced.
이러한 자동차에서 발생되는 배기소음은, 소음기(3) 투과음과 소음기(3) 및 배기관(4) 표면에서의 방사음과 배기관(4) 끝에서 토출되면서 나는 토출음으로 분류되며, 이러한 배기 소음은 기관(1)의 배기밸브와 배기공이 열릴 때, 실린더 내에서 압력이 큰 배기가스가 분출되어 와류와 진동을 야기시키기 때문에 발생되는데, 기관의 출력과 축토오크가 증가하면 배기소음도 증가하고, 배기관(4)의 길이가 길어지면 배기소음이 감소되고 배압(back)이 증가되어, 기관의 성능이 저하되었다.Exhaust noise generated from such a vehicle is classified into a silencer (3) transmission sound, a silencer (3) and the exhaust sound from the surface of the exhaust pipe (4) and the discharge sound emitted from the end of the exhaust pipe (4), the exhaust noise is When the exhaust valve and the exhaust hole of the engine 1 are opened, it is generated because the exhaust gas with a high pressure is ejected in the cylinder, causing vortex and vibration, and when the engine output and shaft torque increase, the exhaust noise also increases, and the exhaust pipe ( The longer the length of 4), the lower the exhaust noise and the higher the back pressure, which lowered the engine performance.
따라서, 자동차의 배기관은 배기소음을 줄이기 위해 배기관의 길이만 길게 형성할 수는 없으며, 기관의 출력향상만을 위해 배기관의 길이를 짧게 형성하는 것도 바람직하지 못하며, 배기소음과 기관의 출력을 적절히 고려한 상태에서, 효율성을 높이는 것이 설계의 과제이다.Therefore, the exhaust pipe of an automobile cannot form only the length of the exhaust pipe to reduce the exhaust noise, and it is not desirable to form the exhaust pipe short for the purpose of improving the output of the engine, and the exhaust noise and the output of the engine are properly considered. Increasing efficiency is a design challenge.
본 고안의 목적은 상기와 같은 종래의 과제를 해소하기 위해, 기관의 회전수(rpm) 및 드로틀밸브(throttle valve)의 개폐정도에 따라 전자기식액츄에이터에 의해 가변배기관의 길이가 가변되도록 하여, 기관의 성능과 관련하여 배기관의 길이를 조정하도록 하는 자동차의 가변 배기관장치를 제공하는 데 있다.An object of the present invention is to solve the conventional problems as described above, by varying the length of the variable exhaust pipe by the electromagnetic actuator according to the rotational speed (rpm) and opening and closing degree of the throttle valve (throttle valve) of the engine, The present invention provides a variable exhaust pipe system for a vehicle to adjust the length of the exhaust pipe in relation to the performance of the vehicle.
