유량 가변형 볼텍스 튜브 엔진 시스템{VARIABLE FLUX TYPE VORTEX TUBE ENGINE SYSTEM}VARIABLE FLUX TYPE VORTEX TUBE ENGINE SYSTEM}

본 발명은 유량 가변형 볼텍스 튜브 엔진 시스템에 관한 것으로, 구체적으로는 배기가스의 압력에 따라 볼텍스 튜브에서 분리되는 고온 및 저온 배기가스의 양을 조절하여 에너지 분리효율을 극대화함으로써 엔진의 출력을 향상시키고 매연을 저감할 수 있는 유량 가변형 볼텍스 튜브 엔진 시스템에 관한 것이다.The present invention relates to a variable flow vortex tube engine system, specifically, to control the amount of hot and cold exhaust gases separated from the vortex tube according to the pressure of the exhaust gas to maximize the energy separation efficiency to improve the output of the engine and soot It relates to a variable flow vortex tube engine system that can reduce the flow rate.

볼텍스 튜브(Vortex Tube)란, 고속으로 회전하는 공기의 자발적인 에너지 분리현상을 이용하여 고온 및 저온의 공기를 발생하는 장치이다. 이러한 볼텍스 튜브는 각종 기계, 전기 및 전자장비의 냉각수단으로 사용되는 것이 일반적이되, 최근에는 자동차의 엔진에 장착되어 엔진의 출력을 상승시킴과 동시에 매연을 저감하는 수단으로 사용되기도 한다.Vortex tube is a device that generates high-temperature and low-temperature air by using spontaneous energy separation of air rotating at high speed. The vortex tube is generally used as a cooling means for various mechanical, electrical and electronic equipment, but recently, it is used as a means for reducing the smoke while increasing the output of the engine mounted on the engine of the vehicle.

도 3은 본 출원인에 의해 기 출원된 이지알 쿨러 대체용 볼텍스 튜브가 장착된 엔진 시스템(특허등록 제10-759516호)의 개략도로, 도면을 참조하여 설명하면 다음과 같다.FIG. 3 is a schematic diagram of an engine system (Patent Registration No. 10-759516) equipped with a Vortex tube for replacing an RG cooler previously filed by the present applicant, and will be described with reference to the accompanying drawings.

이지알(EGR: Exhaust Gas Recirculation) 쿨러 대체용 볼텍스 튜브가 장착된 엔진 시스템(1)은 이지알 장치를 포함하는 디젤자동차용 엔진 시스템으로, 흡입구(12)와 저온 및 고온출구(14, 16)를 갖는 볼텍스 튜브(10)를 포함한다. 이때, 상기 흡입구(12)는 배기배관(20)의 분기점(22)에서 나뉜 제 1 배기배관(24)을 통해 배기매니폴드(30)에 연결되고, 상기 저온출구(14)는 이지알 밸브(40)를 경유하여 흡기매니폴드(50)에 연결되며, 상기 고온출구(16)는 배기라인(92)을 통해 매연여과장치(60)에 연결되고, 상기 배기배관(20)의 분기점(22)에는 제 2 배기배관(26)이 분기되며, 이 제 2 배기배관(26)은 매연여과장치(60)에 연결된다.An engine system (1) equipped with an Exhaust Gas Recirculation (EGR) cooler replacement vortex tube is an engine system for a diesel vehicle including an EZR device, and includes an inlet 12 and a low temperature and high temperature outlet 14 and 16. It includes a vortex tube 10 having. At this time, the inlet 12 is connected to the exhaust manifold 30 through the first exhaust pipe 24 divided at the branch 22 of the exhaust pipe 20, the low temperature outlet 14 is an IG valve ( 40 is connected to the intake manifold 50 via the inlet manifold 50, and the high temperature outlet 16 is connected to the soot filtration device 60 through the exhaust line 92, and the branch point 22 of the exhaust pipe 20. The second exhaust pipe 26 is branched to the second exhaust pipe 26 is connected to the soot filtration device (60).

이와 같이 구성된 이지알 쿨러 대체용 볼텍스 튜브가 장착된 엔진 시스템(1)은 배기배관(20)을 통해 배출되는 배기가스의 일부를 볼텍스 튜브(10)로 순환시켜 고온 및 저온의 배기배출물입자가 분리된 배기가스로 분리한다. 그리고 고온의 배기가스는 매연여과장치(60)로 공급하고 저온의 배기가스는 흡기매니폴드(50)로 공급하여 이지알 시스템 적용시 엔진의 출력을 상승시킴과 동시에 매연을 저감한다.The engine system 1 equipped with the EGX cooler replacement vortex tube configured as described above circulates a part of the exhaust gas discharged through the exhaust pipe 20 to the vortex tube 10 to separate the high and low temperature exhaust emission particles. To the exhaust gas. The high temperature exhaust gas is supplied to the soot filtration device 60, and the low temperature exhaust gas is supplied to the intake manifold 50 to increase the output of the engine and reduce the smoke at the time of application of the EZR system.

그런데 상기 볼텍스 튜브(10)는 고온출구(16)에서 배출되는 고온 배기가스의 양이 흡입구(12)에서 흡입되는 배기가스량의 10 ~ 20%일 경우에만 에너지 분리효율이 우수하다. 따라서 엔진의 구동 초기 또는 가속할 경우와 같이 배기가스의 양의 적거나 혹은 많을 경우에는 에너지 분리효율이 낮아져 엔진의 출력이 저하되고 매연의 발생량이 증가하게 된다. 특히, 매연여과장치(60)로 공급되는 배기가스의 온도가 낮을 경우 매연의 재생이 어려워 대기환경에 매우 치명적인 질화산화물(NOx) 및 입자상물질(PM: Particulate Matter)이 증가하는 문제가 발생된다.However, the vortex tube 10 has an excellent energy separation efficiency only when the amount of the hot exhaust gas discharged from the high temperature outlet 16 is 10 to 20% of the amount of the exhaust gas sucked from the inlet 12. Therefore, when the amount of exhaust gas is small or large, such as when the engine is initially driven or accelerated, the energy separation efficiency is lowered, thereby lowering the output of the engine and increasing the amount of smoke generated. In particular, when the temperature of the exhaust gas supplied to the soot filtration device 60 is low, it is difficult to regenerate the soot, which causes a problem of increasing nitric oxide (NO x ) and particulate matter (PM) which are very fatal to the atmosphere. .

본 발명은 상술한 제반 문제점을 해결하기 위한 것으로서 배기가스의 압력에 따라 볼텍스 튜브에서 분리되는 고온 및 저온 배기가스의 양을 조절하여 에너지 분리효율을 극대화함으로써 엔진의 출력을 향상시키고 매연을 저감할 수 있는 유량 가변형 볼텍스 튜브 엔진 시스템을 제공하는데 그 목적이 있다.The present invention is to solve the above-described problems, by adjusting the amount of hot and cold exhaust gas separated from the vortex tube according to the pressure of the exhaust gas to maximize the energy separation efficiency to improve the output of the engine and reduce the smoke The purpose is to provide a variable flow vortex tube engine system.

상기 엔진 시스템에 마련되는 볼텍스 튜브는 그 흡입구, 고온출구 및 저온출구가 엔진의 배기배관, 매연여과장치 및 흡기배관에 각각 연결되고, 상기 배기배관에는 배기가스의 압력을 측정하기 위한 제 1 압력센서가 마련되며, 상기 고온출구에는 제 1 압력센서에서 측정된 배기가스의 압력에 따라 개폐량이 조절되는 스로틀밸브가 마련된다.The vortex tube provided in the engine system has a suction port, a high temperature outlet, and a low temperature outlet connected to an exhaust pipe, a soot filtration device, and an intake pipe of the engine, respectively, and the exhaust pipe has a first pressure sensor for measuring the pressure of the exhaust gas. Is provided, the high temperature outlet is provided with a throttle valve which is controlled the opening and closing amount according to the pressure of the exhaust gas measured by the first pressure sensor.

이때, 상기 스로틀밸브는 제 1 압력센서에서 측정된 배기가스의 압력, 좀 더 상세하게는 측정된 압력에 의해 산출되는 배기가스의 양에 따라 개폐량이 조절되는데, 산출된 배기가스의 10 ~ 20%만 고온출구로 배출되도록 개폐량을 조절하면 에너지 분리효율을 극대화할 수 있다.In this case, the opening and closing amount of the throttle valve is adjusted according to the amount of the exhaust gas calculated by the pressure of the exhaust gas measured by the first pressure sensor, more specifically, the measured pressure, 10 to 20% of the calculated exhaust gas By adjusting the opening and closing amount to be discharged to the high temperature outlet, the energy separation efficiency can be maximized.

상술한 바와 같이 구성된 본 발명에 의한 유량 가변형 볼텍스 튜브 엔진 시스템은 배기가스의 압력(압력에 의해 산출되는 배기가스의 양)에 따라 스로틀밸브의 개폐량을 조절하여 볼텍스 튜브의 에너지 분리효율을 극대화할 수 있다.The variable flow vortex tube engine system according to the present invention configured as described above can maximize the energy separation efficiency of the vortex tube by adjusting the opening and closing amount of the throttle valve according to the pressure of the exhaust gas (the amount of the exhaust gas calculated by the pressure). Can be.

또한, 볼텍스 튜브에서 분리된 고온 및 저온의 배기가스는 종래의 볼텍스 튜브에서 분리된 배기가스에 비하여 온도가 더 높거나 더 낮으므로 질화산화물(NOx) 및 입자상물질(PM)의 배출을 방지하여 매연을 저감할 수 있으며, 엔진의 출력도 향상시킬 수 있다.In addition, the hot and cold exhaust gas separated from the vortex tube has a higher or lower temperature than the exhaust gas separated from the conventional vortex tube, thereby preventing the release of nitride oxides (NO x ) and particulate matter (PM). Soot can be reduced and engine output can be improved.

In addition, the opening and closing amount of the second solenoid valve 184 is adjusted according to the pressure of the low temperature pipe 144 measured by the second pressure sensor 174.

상기 매연여과장치(160)는 DPF(Diesel Particulate Filter) 또는 CPF(Catalyzed Particulate Filter)라고 하며, 다양한 방식의 매연여과장치가 사용될 수 있다. 일례로, 별도의 재생장치(PM 산화)가 없는 단순 필터 방식의 여과장치를 사용하더라도 상기 볼텍스 튜브(150)에서 유입되는 배기가스의 온도가 매연여 과장치의 자연 재생온도(600 ~ 650℃) 이상이므로 재생이 가능하여 입자상물질(PM)의 제거할 수 있다.The soot filtration device 160 is called a diesel particulate filter (DPF) or a catalyzed particulate filter (CPF), and various soot filters may be used. For example, even when a simple filter type filtration device without a separate regeneration device (PM oxidation) is used, the temperature of the exhaust gas flowing from the vortex tube 150 is higher than the natural regeneration temperature of the soot filtration device (600 to 650 ° C.). Therefore, it is possible to regenerate and remove particulate matter (PM).

상술한 바와 같은 구성을 갖는 본 발명에 의한 유량 가변형 볼텍스 튜브 엔진 시스템(100)의 재순환과정을 살펴보면 다음과 같다.Looking at the recirculation process of the variable flow vortex tube engine system 100 according to the present invention having the configuration as described above are as follows.

상기 엔진(110)은 흡기배관(120)을 통해 유입된 외부 공기를 혼합하여 연료를 연소시키고, 연소시 발생된 배기가스는 배기배관(130)을 통해 볼텍스 튜브(150)로 배출한다.The engine 110 mixes the outside air introduced through the intake pipe 120 to combust the fuel, and exhaust gas generated during combustion is discharged to the vortex tube 150 through the exhaust pipe 130.

상기 배기배관(130)에 배기가스가 유입되면 컨트롤러(190)는 제 1 압력센서(172)를 통해 배기가스의 압력을 측정하고, 측정된 압력 수치를 이용하여 배기가스의 양을 산출한다. 그리고 산출된 배기가스의 양에 따라 스로틀밸브(158)의 일측에 마련된 전동기(159)를 작동시켜 스로틀밸브(158)의 개폐량을 조절한다. When the exhaust gas flows into the exhaust pipe 130, the controller 190 measures the pressure of the exhaust gas through the first pressure sensor 172, and calculates the amount of exhaust gas using the measured pressure value. In addition, the opening and closing amount of the throttle valve 158 is adjusted by operating the electric motor 159 provided on one side of the throttle valve 158 according to the calculated amount of exhaust gas.

이때, 상기 컨트롤러(190)는 볼텍스 튜브(150)의 에너지 분리효율을 극대화할 수 있도록 볼텍스 튜브(150)로 유입되는 배기가스의 10 ~ 20%만 고온출구(154)로 배출되도록 스로틀밸브(158)의 개폐량을 조절한다.At this time, the controller 190 throttle valve 158 so that only 10 to 20% of the exhaust gas flowing into the vortex tube 150 is discharged to the high temperature outlet 154 so as to maximize the energy separation efficiency of the vortex tube 150. Adjust the amount of open / close

상기 볼텍스 튜브(150)로 유입된 배기가스는 고온 및 저온의 배기가스로 분리된다. 이 중 고온의 배기가스는 고온배관(142)을 통해 매연여과장치(160)로 유입되어 입자상물질(PM)을 제거하는데 사용되며, 저온의 배기가스는 저온배관(144)을 통해 흡기배관(120)으로 유입되어 엔진의 출력을 향상시키는데 사용된다.The exhaust gas introduced into the vortex tube 150 is separated into exhaust gases of high temperature and low temperature. The high temperature exhaust gas is introduced into the soot filtration device 160 through the high temperature pipe 142 and used to remove particulate matter (PM), and the low temperature exhaust gas is intake pipe 120 through the low temperature pipe 144. Is used to improve engine power.

반면, 배기가스의 10 ~ 20%이하만 고온출구(154)로 배출되도록 스로틀밸브(158)의 개폐량을 조절하면, 볼텍스 튜브(150)의 에너지 분리효율은 향상되지만 그 내부의 유동 저항 또한 함께 증가하게 되어 엔진의 출력을 저하시키고 연료소비를 증대시킬 우려가 있다. 이러한 경우 스로틀밸브(158)의 개폐량을 증가시키거나 상기 컨트롤러(190)는 제 1 압력센서(172)에서 측정된 배기가스의 압력이 설정압보다 높을 경우 제 1 전자밸브(182)를 개방하여 배기가스의 일부를 매연여과장치(160)로 직접 배출하여 유동저항을 감소시킬 수 있다.On the other hand, if the amount of opening and closing of the throttle valve 158 is controlled so that only 10 to 20% or less of the exhaust gas is discharged to the high temperature outlet 154, the energy separation efficiency of the vortex tube 150 is improved, but the flow resistance therein is also increased. There is a risk of increasing the power output of the engine and increase the fuel consumption. In this case, the opening / closing amount of the throttle valve 158 is increased or the controller 190 opens the first solenoid valve 182 when the pressure of the exhaust gas measured by the first pressure sensor 172 is higher than the set pressure. Part of the exhaust gas may be directly discharged to the soot filtration device 160 to reduce the flow resistance.

상술한 바와 같이 배기가스의 압력에 따라 스로틀밸브(158)의 개폐량을 능동적으로 제어할 경우 볼텍스 튜브(150) 내의 유동저항이 감소하게 되어 볼텍스 튜브(150)를 추가 장착함에 따른 엔진 시스템의 배기 배압 상승을 억제할 수 있다.As described above, when actively controlling the opening / closing amount of the throttle valve 158 according to the pressure of the exhaust gas, the flow resistance in the vortex tube 150 is reduced, so that the exhaust of the engine system by additionally installing the vortex tube 150. The back pressure rise can be suppressed.
