Description

내연기관의 출력 증강을 위한 소음 저감형 흡기장치Noise reduction intake system for power output of internal combustion engine
본 발명은 내연기관의 출력 증강을 위한 소음 저감형 흡기 장치에 관한 것으로, 더욱 상세히게는 자동차와 같은 내연기관의 흡기부에 설치되어 공기 와류발생기를 설치하여 흡배기되는 공기를 회전하는 와류로 만들어 공기의 흐름을 향상시켜 흡배기효율에 따른 출력향상을 통해 연소효율을 향상시켜 연비가 향상되도록 하고 유동 박리현상에 따른 소음을 저감시키며 매연을 감소시키고 엔진의 수명을 연장시키는 내연기관의 출력 증강을 위한 소음 저감형 흡기 장치에 관한 것이다.The present invention relates to a noise reduction intake apparatus for enhancing the output of an internal combustion engine, and more particularly, is installed in the intake portion of an internal combustion engine such as an automobile to install an air vortex generator to make the air intake and exhaust into a rotating vortex Noise for enhancing the output of the internal combustion engine that improves the flow of fuel and improves the fuel efficiency by improving the output according to the intake and exhaust efficiency, reduces the noise caused by the flow separation phenomenon, reduces the smoke and extends the engine life. It relates to a reduced type intake apparatus.
통상적으로, 디젤 엔진에는 고속 주행시 흡기의 과급으로 고속주행의 용이성을 제공하고, 또한 배기가스 규제 및 CO2규제등에 대응하기 위하여 기본적으로 터보 차져(Turbo Charger)와 인터쿨러(Intercooler)가 설치되고 있다.In general, a diesel engine is basically provided with a turbo charger and an intercooler in order to provide high-speed driving ease by supercharging intake air at high speed, and to cope with exhaust gas regulation and CO 2 regulation.
상기 터보차져는 일종의 송풍기와 같으며, 엔진의 배기 매니폴드로 빠져나가는 배기가스의 유동에너지를 이용한 것이다.The turbocharger is a kind of blower and utilizes the flow energy of the exhaust gas exiting the exhaust manifold of the engine.
따라서, 상기 배기가스의 유동에너지로 인하여, 터보차져의 터빈이 회전을 하게 되고, 동시에 맞은편에 동축을 이루며 설치된 컴프레서가 회전됨으로써, 이 컴프레서에 의하여 흡기가 흡입 및 가압되어 엔진 실린더의 연소실로 과급으로 공급되어진다.Accordingly, due to the flow energy of the exhaust gas, the turbine of the turbocharger rotates, and at the same time, the compressor installed while being coaxially opposite is rotated, so that the intake air is sucked and pressed by the compressor to supercharge the combustion chamber of the engine cylinder. Is supplied.
이때, 상기 터보챠져만 장착한 디젤 엔진의 경우에 흡입 공기의 압력은 증대시킬 수 있으나, 공기를 압축하는 과정에서 공기의 온도가 상승하는 문제로 연소온도 및 배기 온도의 증가와 더불어 실질적인 충진 효율 개선폭의 저하현상이 문제가 된다.In this case, in the case of the diesel engine equipped with only the turbocharger, the pressure of the intake air can be increased, but due to the problem that the temperature of the air increases in the process of compressing the air, the combustion temperature and the exhaust temperature are increased, and the actual filling efficiency is improved. Is a problem.
이에, 흡기라인에 인터쿨러를 설치하여, 과급되는 흡기를 인터쿨러 에서 냉각시켜, 과급으로 인한 흡기의 열발생을 차단함과 함께 냉각된 흡기를 연소실로 공급함으로써, 연소실의 충진 효율을 향상시킬 수 있다.Thus, by installing an intercooler in the intake line, the supercharged intake air is cooled in the intercooler, thereby preventing heat generation of intake air due to supercharging and supplying the cooled intake air to the combustion chamber, thereby improving the filling efficiency of the combustion chamber.
이와 같이, 터보차져와 인터쿨러를 이용한 디젤엔진의 흡기 시스템은 흡기공기량을 증대시켜 배기가스 저감 및 연비향상, 엔진소음 저감, 연비 개선등의 효과를 얻고 있다.As described above, the intake system of a diesel engine using a turbocharger and an intercooler increases the amount of intake air, thereby reducing the exhaust gas, improving fuel efficiency, reducing engine noise, and improving fuel efficiency.
이러한 잇점에도 불구하고, 터보차쳐와 인터쿨러를 이용하는 디젤엔진의 경우 다음과 같은 문제점이 있다.Despite these advantages, diesel engines using turbochargers and intercoolers have the following problems.
연소효율 및 펌핑 로스(Pumping Loss)의 개선을 위해 다량의 공기를 흡입하여, 이 중 일부를 순수 연소 반응에 이용하게 되고, 이 경우 대기중의 80% 정도 함유되어 있는 질소가 필수 불가결하게 흡입되며, 고온/고압의 연소과정 중에서 산소와 반응하여 디젤 엔진에서 가장 문제가 되는 질소 산화물(Nox)을 생성하게 된다.In order to improve combustion efficiency and pumping loss, a large amount of air is sucked and some of them are used for the pure combustion reaction, in which case nitrogen containing about 80% of the atmosphere is indispensable. In the combustion process of high temperature / high pressure, it reacts with oxygen to produce nitrogen oxide (Nox) which is the most problematic in diesel engines.
연소 조건을 개선하기 위해서는 고온 고압의 연소실 분위기가 필요하나 상대적으로 이 조건에서 질소산화물의 생성이 용이하여 연소개선을 통한 연비 개선 및 스모크(SMOKE)와 같은 배출가스 성분을 줄이는데 한계가 있다.In order to improve the combustion conditions, a high temperature and high pressure combustion chamber atmosphere is required, but it is relatively easy to generate nitrogen oxides in this condition, and thus there is a limit in improving fuel efficiency and reducing exhaust gas components such as smoke (SMOKE).
또한, 터보챠져와 인터쿨러가 적용된 디젤 엔진의 경우, 터버 챠져 시스템을통한 성능 향상은 가능하나, 터보챠져의 특성상 전 사용 영역에 대한 흡기 특성 개선이 불가능하여, 부득이 저속 저부하와 같은 특정 구간에서의 성능저하 현상을 피할 수 없게 된다.In addition, in the case of a diesel engine equipped with a turbocharger and an intercooler, it is possible to improve the performance through the turbocharger system, but due to the characteristics of the turbocharger, it is impossible to improve the intake characteristics of the entire use area, so it is inevitable in a specific section such as a low speed low load. Performance degradation is inevitable.
이와 같은 특성을 개선하기 위하여, 최근에는 터보챠져에 웨이스트 게이트 밸브(Waste Gate Valve)를 장착하여 부분적인 흡기 성능 개선을 하고 있으나 근본적인 개선은 어려운 상태에 있다.In order to improve such characteristics, recently, a waste gate valve is mounted on a turbocharger to partially improve intake performance, but fundamental improvements are difficult.
그리고 대한민국 특허등록번호 제1754042호와 같이 차량의 흡배기관내 공기 와류발생기를 설치하여 공기의 흐름을 고속으로 유도하는 와류 발생장치를 통하여 공기의 흡입력과 배출력을 증대시켜 수명을 연장하는 것이었다.In addition, the air vortex generator is installed in the intake and exhaust pipe of the vehicle, such as Korean Patent Registration No. 17564042, to extend the life by increasing the suction power and discharge power of the air through the vortex generator which induces the flow of air at high speed.
그러나 상기 종래기술들은 구조가 복잡하거나 와류가 원활하게 발생되지 않는 좌측방향으로 와류를 발생시켜 공급하게 되므로 흡배기되는 공기의 흐름이 빠르지 않은 단점과, 날개와 바람이 분리되는 유동 박리현상이 발생되고, 이러한 유동 박리현상은 공기 흐름을 불규칙적으로 만들어 소음을 발생시키며 흡입력에 손실을 가져다 주며 이로 인한 진동이 형성되는 단점이 있었다.However, the conventional technologies are disadvantageous in that the flow of the intake and exhaust air is not fast, and the flow separation phenomenon that separates the wing and the wind occurs because the vortex is generated and supplied to the left direction in which the structure is complicated or the vortex does not occur smoothly. This phenomenon of flow separation causes irregular air flow, generates noise, causes loss in suction force, and has a disadvantage of vibration.
따라서 이러한 종래의 결점을 해소하기 위하여 안출된 것으로 본 발명의 해결과제는, 자동차의 흡입구쪽에 설치되어 와류를 발생시키는 날개의 굴곡부로 인해 유동 박리현상을 줄여 공기의 흐름을 원활하게 하여 연소효율을 향상시켜 연비를 향상시키고, 매연을 감소하며 엔진의 수명연장과 소음을 감소시키는 것을 목적으로 한다.Therefore, the problem to be solved by the present invention is to solve the above-mentioned drawbacks. The problem of the present invention is that the bend of the wing installed on the inlet side of the vehicle generates the vortex, thereby reducing the flow separation phenomenon and improving the combustion efficiency by smoothing the flow of air. To improve fuel economy, reduce soot and reduce engine life and noise.
본 발명의 다른 해결과제는, 내경관의 입구와 출구의 크기를 조절하여 베르누이 원리에 따른 과급기 역할과 내경관의 내경에 설치하는 와류 돌기의 돌출에 의한 와류를 형성하는 것을 목적으로 한다.Another object of the present invention is to adjust the size of the inlet and outlet of the inner diameter tube to form a vortex due to the role of the supercharger according to the Bernoulli principle and the protrusion of the vortex protrusion installed on the inner diameter of the inner diameter tube.
