Description

배기량을 극대화한 차량용 서브 머플러 구조{A Sub Muffler Sturucture of Vehicles Having the Largest Enging Displacement}A Sub Muffler Sturucture of Vehicles Having the Largest Enging Displacement}

본 고안은 배기량을 극대화한 차량용 서브 머플러 구조에 관한 것으로, 특히 서브 머플러 하우징 내부에 3개의 공간부가 형성되도록 2개의 원통형 격벽을 설치하고, 제 1 원통형 격벽 내부에 스크류를 내장시키며, 제 2 원통형 격벽의 전후단에 배기가스의 원할한 출력을 위해 다수개의 홀을 형성토록 하여 배기가스가 서브 머플러를 통과하면서 배출시에 배기가스의 배압(back pressure)을 저감토록 함으로써, 엔진의 저속 및 고속상태에서의 출력을 극대화시키도록 한 것을 특징으로 하는 배기량을 극대화한 차량용 서브 머플러 구조에 관한 것이다.The present invention relates to a vehicle submuffler structure that maximizes displacement, and in particular, two cylindrical partitions are installed so that three spaces are formed inside the submuffler housing, a screw is embedded in the first cylindrical partition, and a second cylindrical partition is provided. By forming a plurality of holes in front and rear of the exhaust gas for a smooth output of the exhaust gas, the exhaust gas passes through the sub muffler to reduce the back pressure of the exhaust gas at the time of discharge, thereby reducing the engine's low and high speed. It relates to a vehicle sub muffler structure that maximizes the displacement, characterized in that to maximize the output of.

일반적으로 차량은 공기와 적당한 비율로 혼합된 혼합기를 실린더로 흡입하여 압축시킨 다음 점화와 팽창을 통해 발생되는 직선운동을 커넥팅 로드와 크랭크를 이용하여 토크를 갖는 회전운동으로 변환시켜 구동력을 발생시키고, 여기서 발생된 구동력을 바퀴에 전달하여 차량의 주행이 가능토록 한다.In general, the vehicle inhales and compresses a mixer mixed with air at an appropriate ratio, and converts the linear motion generated by ignition and expansion into a rotational motion with torque by using a connecting rod and a crank to generate driving force. The driving force generated here is transmitted to the wheels to allow the vehicle to travel.

그리고, 혼합기가 점화되면서 발생된 연소가스는 도 1에 도시한 바와 같이 엔진(100)에 구비된 배기매니폴드를 통해 한곳으로 모아진후 촉매 컨버터(200)를 통과하는 과정에서 일산화탄소와 탄화수소 및 질소화합물 등이 촉매로 인해 화원되고, 환원된 상태로 연결 파이프를 통해 서브 머플러(300) 및 메인 머플러(400)로 유입된다.In addition, the combustion gas generated while the mixer is ignited is collected in one place through the exhaust manifold provided in the engine 100, and then passed through the catalytic converter 200. The back is fired by the catalyst and is introduced into the sub muffler 300 and the main muffler 400 through the connection pipe in a reduced state.

상기 서브머플러(300)로 유입된 연소가스는 다수의 팽창과정을 통해 압력이 낮아지고, 서브 머플러(300)의 토출측에 연결된 파이프를 경유하여 다수의 격막을 갖는 소음기(메인 머플러(400))를 통과하면서 배출소음이 출어들고, 배기가스는 외부 공기중으로 배출된다.Combustion gas introduced into the submuffler 300 has a low pressure through a plurality of expansion processes, and includes a silencer (main muffler 400) having a plurality of diaphragms via a pipe connected to the discharge side of the submuffler 300. Exhaust noise is blown out as it passes, and exhaust gas is discharged to the outside air.

그러나, 연소가스가 서브 머플러(300)를 통과하는 과정에서 압력과 유속이 낮아져 배출저항으로 작용함으로서 엔진의 출력이 감소되고, 엔진의 출력을 높이기 위해 가속페달을 밝아 엔진의 사이클 행정을 빠르게 함으로서 차량의 주행속도를 높일 수 있으나, RPM의 증가와 연료가 불완전 연소되므로 연료가 낭비되는 문제점이 있었다.However, as the combustion gas passes through the submuffler 300, the pressure and the flow rate are lowered, which acts as a discharge resistance, thereby reducing the output of the engine, and by accelerating the engine to increase the output of the engine. Although it can increase the running speed, there was a problem that the fuel is wasted because the increase in RPM and fuel is incomplete combustion.

본 고안은 상기와 같은 문제를 해결코자 하는 것으로, 저알피엠시에는 스크류를 통해 배기가스가 출력되도록 하고, 고알피엠시에는 스크류를 통해 배기가스가 출력되도록 하되, 제3 소음실과 배기가스 통기용 격벽의 통기용 홀 그리고 제2 원통형 격벽의 통기용 홀을 만들어 줌으로써 배기가스 통기용 격벽 입구에서 배압저항은 물론 진동과 소음을 줄여주어 엔진효율을 극대화 시키도록 하는데 그 목적이 있다.The present invention is to solve the above problems, the exhaust gas is output through the screw in the low PMC, and the exhaust gas is output through the screw in the high RF, but the third noise chamber and the exhaust gas vent partition The purpose of the present invention is to maximize the engine efficiency by reducing the back pressure resistance, vibration and noise at the inlet of the exhaust gas ventilation partition by making the ventilation hole and the ventilation hole of the second cylindrical partition wall.

이하에서 본 고안의 구성을 보다 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the present invention in more detail.

본 고안의 서브 머플러(300)는 중심부에 제 1 원통형 격벽(320)이 설치되고, 상기 제 1 원통형 격벽(320)과 일정거리 이격되어 제 2 원통형 격벽(340)이 설치되며, 상기 제 2 원통형 격벽(340)에 일정거리 이격되어 하우징(310)이 설치되어 이루어지며, 이에 따라서 제 1 원통형 격벽(320) 내부에 제 1 소음실(300a)이 형성되고, 제 1 원통형 격벽(320)과 제 2 원통형 격벽(340) 사이에 제 2 소음실(300b)이 형성되며, 제 2 원통형 격벽(340)과 하우징(310) 사이에 제 3 소음실(300c)이 형성된다.In the sub muffler 300 of the present invention, a first cylindrical partition 320 is installed at a central portion thereof, and a second cylindrical partition 340 is installed to be spaced apart from the first cylindrical partition 320 by a predetermined distance. The housing 310 is installed to be spaced apart from the barrier rib 340 by a predetermined distance. Accordingly, a first noise chamber 300a is formed in the first cylindrical barrier rib 320, and the first cylindrical barrier rib 320 and the first cylinder are formed. A second silencer 300b is formed between the two cylindrical partitions 340, and a third silencer 300c is formed between the second cylindrical partition 340 and the housing 310.

상기 제 1 원통형 격벽(320)은 서브 머플러 하우징(300)의 중심부에 설치되는 원통형 형상으로서 일측이 유입용 배기관(510)에 연결되어 있고, 내측에 스크류(330)가 내장된다. 또한, 제 1 원통형 격벽(320)의 좌우에는 통기용 홀(320a)이 형성되어 배기가스가 상기 통기용 홀(320a)을 통해 출입한다.The first cylindrical partition 320 has a cylindrical shape installed at the center of the sub muffler housing 300, one side of which is connected to the intake exhaust pipe 510, and a screw 330 is embedded therein. In addition, ventilation holes 320a are formed at left and right sides of the first cylindrical partition 320 to allow exhaust gas to enter and exit through the ventilation holes 320a.

상기 제 2 원통형 격벽(340)은 제 1 원통형 격벽(320)에 일정거리 이격되어 설치되는 원통형 형상으로서 주연부 전단과 후단에 다수개의 통기용 홀(340a)이 형성되어 압력상황에 따라서 제 2 소음실(300b)에 존재하는 배기가스를 외부로 배출 시키는 역할을 한다.The second cylindrical partition 340 is a cylindrical shape which is installed at a predetermined distance apart from the first cylindrical partition 320 and a plurality of vent holes 340a are formed at the front and rear edges of the second cylindrical chamber according to the pressure situation. It serves to discharge the exhaust gas existing in (300b) to the outside.

상기 배기가스 통기용 격벽(350)은 제 2 원통형 격벽(340)에 연장 설치되는 원통형 형상으로서, 타측이 배기용 배기관(520)과 연결되어 있어 배기가스를 배기용 배기관(520)으로 배출하는 역할을 하고, 또한 주연부에 다수개의 통기용 홀(350a)이 형성되어 있어 제 3 소음실(300c)에 존재하는 배기가스를 흡입하여 배기용 배기관(520)으로 출력하는 역할을 한다.The exhaust gas vent partition wall 350 has a cylindrical shape extending to the second cylindrical partition wall 340, and the other side is connected to the exhaust exhaust pipe 520 to discharge the exhaust gas to the exhaust exhaust pipe 520. In addition, a plurality of vent holes 350a are formed at the periphery, and serve to suck the exhaust gas existing in the third silencer 300c and output the exhaust gas to the exhaust exhaust pipe 520.

상기 제 1 원통형 격벽(320)에는 스크류(330)가 내장되는바, 상기 스크류는 날개가 적어도 1개 설치되며 바람직하게는 3개 설치한다.The screw 330 is built in the first cylindrical partition 320, the screw is provided with at least one wing, preferably three are installed.

상기 스크류(330)는 배기가스가 유입될때 배기가스를 회전시켜 빠른속도로 후방으로 배출하는 역할을 하게 된다. 즉, 배기 메니폴드에서 빠져나온 배기가스가 배기가스 유입용 배기관(510)을 통해 서브 머플러 하우징(510) 내부로 입력되면 스크류(330)의 날개를 타고 회전하면서 출력되므로 제 1 소음실(300a)을 통과하는 배기가스의 배기되는 속도가 빨라지게 되는 것이다.The screw 330 rotates the exhaust gas when the exhaust gas flows in and discharges the gas backward at a high speed. That is, when the exhaust gas exiting from the exhaust manifold is input into the sub muffler housing 510 through the exhaust gas inlet exhaust pipe 510, the exhaust gas is output while rotating on the blade of the screw 330, thereby opening the first noise chamber 300a. The exhaust velocity of the exhaust gas passing through is increased.

이에 따라 악셀레이터를 밟는 초기에 엔진의 출력이 향상되어 저알피엠에서도 차량이 빠른 속도로 운행할 수 있게 된다.Accordingly, the output of the engine is improved at the initial step of the accelerator so that the vehicle can run at high speed even at a low ALPM.

이후, 배기가스의 유입량이 많아지면 스크류(330)를 거쳐서 배기가스가 출력됨과 동시에 제 1 원통형 격벽(320)의 통기용 홀(320a)과 제 2 원통형 격벽(340)의 통기용 홀(340a)을 통해 배기가스가 분출되어 제 2 소음실(300b) 및 제 3 소음실(300c)에도 배기가스가 차오르며, 이때 상기 제 2 소음실(300b) 및 제 3 소음실(300c)에 존재하는 배기가스는 배기가스 통과용 격벽(350)의 통기용 홀(350a) 을 통해 입력되면서 스크류(330)를 통과한 배기가스와 동시에 출력되어 엔진의 출력이 용이하게 이루어지도록 조절된다.Thereafter, when the inflow amount of the exhaust gas increases, the exhaust gas is outputted through the screw 330 and the ventilation hole 320a of the first cylindrical partition 320 and the ventilation hole 340a of the second cylindrical partition 340. The exhaust gas is blown out through the exhaust gas to the second silencer 300b and the third silencer 300c, and the exhaust gas exists in the second silencer 300b and the third silencer 300c. While being input through the vent hole 350a of the exhaust gas passage partition 350 is simultaneously output with the exhaust gas passing through the screw 330 is adjusted to facilitate the output of the engine.

만약에, 제 1 원통형 격벽(320)이나 제 2 원통형 격벽(340)에 통기용 홀(320a, 340a)을 형성하지 않게 되면, 배압저항 때문에 고속에서 효율이 떨어지게 된다. 즉, 스크류(330)를 통해 배출되는 배기가스가 한정되어 있기 때문에 초기 엔진출력은 좋으나, 일정속도 이상에서는 배기가스가 제 1 원통형 격벽(320) 내부에 꽉차게 되어 배압저항이 발생하며 이 때문에 효율이 떨어질 수 밖에 없으며, 이는 배기용 배기관(520)의 출력측으로 빠져나오는 배기가스량이 한계가 있기 때문이다.If the vent holes 320a and 340a are not formed in the first cylindrical partition 320 or the second cylindrical partition 340, the efficiency decreases at high speed due to the back pressure resistance. That is, the initial engine output is good because the exhaust gas discharged through the screw 330 is limited, but the exhaust gas is filled inside the first cylindrical bulkhead 320 at a predetermined speed or more, so that the back pressure resistance is generated, and thus efficiency is increased. This can only fall, because the amount of the exhaust gas exiting to the output side of the exhaust pipe 520 for exhaust is limited.

또한, 만약에 배기가스 통기용 격벽(350)에 홀을 형성하지 않게 되면, 저 알피엠시에는 스크류를 통해 배기가스가 안정적으로 출력하게 되나, 고 알피엠시에는 스크류를 통과한 배기가스유속이 빨라짐으로 인하여 배기가스 통기용 격벽(350) 입구에서 막힘 현상이 발생하고, 이로 인해 엔진출력이 떨어지고, 부밍음과 배기진동이 발생한다. In addition, if a hole is not formed in the exhaust gas aeration partition 350, the exhaust gas is stably output through the screw in the low AlMPH, but the exhaust gas flow rate is increased through the screw in the high AlMPH. As a result, a blockage phenomenon occurs at the inlet of the exhaust gas aeration partition 350, and as a result, the engine output drops, and a booming sound and exhaust vibration occur.

따라서, 저알피엠시에는 스크류(330)를 통해서만 주로 배기가스가 통과되어 제 1 소음실(300a)에 존재하는 배기가스가 배출되고, 고알피엠시에는 스크류(330)를 통해 출력되는 배기가스가 한계를 넘어서면 배기가스가 넘쳐서 제 1 원통형 격벽(320)의 통기용 홀(320a)과 제 2 원통형 격벽(340)의 통기용 홀(340a)을 통해 제 2 소음실(300b) 및 제 3 소음실(300c)에 배기가스가 존재하며, 상기 배기가스는 배기가스 통기용 격벽(350)에 형성된 통기용 홀(350a)을 통해 배기용 배기관(520)으로 배출된다. 이에 따라 배기가스 통기용 격벽(350) 입구에서 배압저항은 물론 진 동과 소음을 줄여주어 엔진효율을 극대화 시키는 장점을 제공하게 된다.Therefore, the exhaust gas mainly passes through the screw 330 through the screw 330 to discharge the exhaust gas existing in the first silencer 300a, and the exhaust gas output through the screw 330 is limited. Exceeds the exhaust gas overflows through the vent hole 320a of the first cylindrical partition wall 320 and the vent hole 340a of the second cylindrical partition wall 340 and the second noise chamber 300b and the third silencer chamber. Exhaust gas is present in the 300c, and the exhaust gas is discharged to the exhaust exhaust pipe 520 through the ventilation hole 350a formed in the exhaust gas ventilation partition wall 350. Accordingly, the back pressure resistance at the inlet of the exhaust gas aeration partition 350 reduces vibration and noise as well as provides an advantage of maximizing engine efficiency.

이때 배기가스 통기용 격벽(350)의 내부는 스크류(330)를 통과한 배기가스가 배출되며, 배출속도가 빠르기 때문에 벤튜리관 역할을 하게 되어 제 3 소음실에 존재하는 배기가스가 통기용 홀(350a)을 통해 배기가스 통기용 격벽(350) 내부로 유입되면서 외부로 배출된다.In this case, the exhaust gas passing through the screw 330 is discharged from the inside of the exhaust gas vent partition wall 350, and the discharge gas is fast, thus acting as a venturi tube, so that the exhaust gas existing in the third noise chamber is vented. 350a) is introduced into the exhaust gas vent partition 350 and discharged to the outside.

이에 따라 통기용 홀(350a)을 통해서도 배기가스의 배출이 이루어지도록 하여 엔진의 출력을 극대화할 수 있고 고알피엠에서도 충분히 차량의 속도를 유지할 수 있게 된다.Accordingly, the exhaust gas is also discharged through the ventilation hole 350a to maximize the output of the engine and to sufficiently maintain the speed of the vehicle even at a high frequency.

결국, 본 고안은 2단계 동작으로 요약할 수 있는바, 엔진이 저알피엠으로 작동시에는 제 1 원통형 격벽(320) 내부의 스크류(330)를 통해 빠른 속도로 배기가스가 배기되어 엔진 출력을 향상시키고, 엔진이 고알피엠으로 작동시에는 스크류 뿐만 아니라 통기용 홀을 통해서도 배기가스가 배기되어 배압저항을 최소화시킴으로서 엔진 출력을 향상시킨다.As a result, the present invention can be summarized as a two-stage operation, when the engine is operated at low PM, exhaust gas is exhausted at a high speed through the screw 330 inside the first cylindrical partition 320 to improve the engine output. In addition, when the engine is operated with high AlPM, the exhaust gas is exhausted not only through the screw but also through the ventilation hole to minimize the back pressure resistance, thereby improving the engine output.
