Description

결합된 EGR 및 배기가스 냉각기 밸브{COMBINED EGR- AND EXHAUST GAS COOLER-VALVE}Combined EGR and exhaust gas cooler valve {COMBINED EGR- AND EXHAUST GAS COOLER-VALVE}

본 발명은 결합된 EGR 및 배기가스 냉각기 밸브 그리고 상기와 같은 밸브를 구비한 배기가스 재순환 시스템(Exhaust Gas Recirculation system)에 관한 것이다.The present invention relates to a combined EGR and exhaust gas cooler valve and an exhaust gas recirculation system having the above valve.

배기가스 재순환 시스템들은 오염 물질의 배출량을 줄이고 내연 기관들의 효율을 향상시키는 데 사용된다. 이 점에 있어 예를 들어, 터보 과급기가 달린 디젤 엔진(supercharged diesel engine)들의 경우, 배기가스의 재순환에 의해 질소 산화물 생성이 감소될 수 있다. 배기가스 재순환 시스템에서, 배기가스 재순환 밸브는 배기가스의 일부를 배기 매니폴드(exhaust manifold)로부터 다시, 신선 공기와 혼합되는 엔진의 흡기 장치로 안내한다. 이 경우 단점은, 재순환된 고온의 배기 공기로 인해 엔진의 흡입 공기가 전체적으로 가열되고, 이는 엔진 성능을 저하시킬 수 있다는 것이다. 이러한 이유로, 상이한 엔진 상태에 대해 상이한 냉각 용량을 제공하도록 제어 방식으로 관류될 수 있고, 경우에 따라 선택적으로 스위칭될 수 있는 하나 또는 다수의 EGR 냉각기를 갖는 엔진들이 개발되었다. DE 10 2016 211 725 A1호에는 2개의 배기가스 냉각기를 위한 효율적인 밸브 장치가 공지되어 있다. 그러나 특정 작동 상태들은 특히, 단일 배기가스 냉각기가 있는 경우에는 나타날 수 없다.Exhaust gas recirculation systems are used to reduce pollutant emissions and improve the efficiency of internal combustion engines. In this respect, for example, in the case of supercharged diesel engines, the production of nitrogen oxides can be reduced by recirculation of the exhaust gas. In the exhaust gas recirculation system, the exhaust gas recirculation valve guides a portion of the exhaust gas from the exhaust manifold back to the intake device of the engine where it is mixed with fresh air. The disadvantage in this case is that the recirculated hot exhaust air heats the intake air of the engine as a whole, which can degrade engine performance. For this reason, engines have been developed that have one or more EGR coolers that can be flown through in a controlled manner to provide different cooling capacities for different engine conditions and can be selectively switched in some cases. In DE 10 2016 211 725 A1 an efficient valve arrangement for two exhaust gas coolers is known. However, certain operating conditions cannot be seen, especially in the presence of a single exhaust gas cooler.

이러한 배경에서 본 발명의 과제는 다수의 작동 상태가 실현될 수 있는 결합된 EGR 및 배기가스 냉각기 밸브를 제공하는 것이다.In this background, the object of the present invention is to provide a combined EGR and exhaust gas cooler valve in which multiple operating states can be realized.

상기 과제의 해결책은 청구항 1에 설명된 밸브에 의해 해결된다.The solution to this problem is solved by the valve described in claim 1.

따라서 상기 밸브는 유입구, 제1 유출구, 제2 유출구 그리고 추가 개구를 구비하며, 상기 유입구와 상기 제1 유출구는 서로 연통되며, 상기 유입구와 상기 제2 유출구 사이에 그리고 상기 유입구와 상기 추가 개구 사이에는 각각 탄성적으로 지지되어 각각 상기 제2 유출구와 상기 추가 개구를 선택적으로 폐쇄 가능한 밸브 부재가 제공되어 있다. 그리고 상기 밸브 부재들은, 상기 제2 유출구와 상기 추가 개구를 모두 폐쇄하거나 또는 상기 제2 유출구와 상기 추가 개구를 개별적으로 개방할 수 있도록 공동 샤프트 상에 탄성적으로 지지되어 있다. 바꾸어 말하면, 공동 샤프트의 운동이, 상기 밸브 부재들 중 하나의 밸브 부재가 개방될 정도로 다른 밸브 부재의 폐쇄 방향으로 힘을 유도한다. Thus, the valve has an inlet, a first outlet, a second outlet and an additional opening, the inlet and the first outlet communicate with each other, between the inlet and the second outlet and between the inlet and the additional opening A valve member is provided, each of which is elastically supported and capable of selectively closing the second outlet and the additional opening, respectively. And the valve members are elastically supported on the common shaft so as to close both the second outlet and the additional opening or to open the second outlet and the additional opening separately. In other words, the motion of the hollow shaft induces a force in the closing direction of the other valve member such that one of the valve members opens.

이로 인해 2개의 밸브 부재가 폐쇄된 경우, 예를 들어 전체 배기가스가 유입구로부터 예를 들어 배기 시스템에 연결될 수 있는 (폐쇄되지 않은) 제1 유출구로 유입되며, 그 결과 배기가스 재순환이 발생하지 않고, 마찬가지로 배기가스 냉각기의 우회도 발생하지 않는 작동 상태가 가능하다. 따라서 배기가스 내에 포함된 전체 열에너지가 예를 들면, 차량 실내를 가열하는 데 사용될 수 있다.In this case, if the two valve elements are closed, for example, the entire exhaust gas is introduced from the inlet to the first outlet (unclosed) which can be connected to the exhaust system, for example, so that no exhaust gas recirculation takes place. Likewise, an operating state in which bypass of the exhaust gas cooler does not occur is possible. Thus, the total thermal energy contained in the exhaust gas can be used, for example, to heat the vehicle interior.

제2 작동 상태에서는, 계속해서 열에너지의 완전한 이용이 가능하나, 제어 가능한, 즉 제2 유출구에 대해 1 내지 100% 사이에서 조절 가능한 밸브의 개방을 통해서 제어 가능한 배기가스 재순환이 이루어질 수 있다. 이러한 작동 상태에서는, 모든 열에너지를 이용할 수 있도록 배기가스가 배기가스 냉각기의 바이패스가 아닌, 계속해서 완전히 배기가스 냉각기를 통해 흐르도록 제2 밸브가 닫힌 상태로 유지된다. 이러한 경우에는 형성된 개구에 상응하게 재순환되지 않은 배기가스가 앞서 제1 배출구로 표기된 배출구를 통해 배기 시스템으로 흐른다.In the second operating state, full use of thermal energy is still possible, but controllable exhaust gas recirculation can be achieved through the opening of a controllable, i.e. adjustable valve between 1 and 100% with respect to the second outlet. In this operating state, the second valve is kept closed so that the exhaust gas continues to flow completely through the exhaust gas cooler rather than the bypass of the exhaust gas cooler so that all thermal energy is available. In this case, the exhaust gas that has not been recirculated corresponding to the formed opening flows into the exhaust system through the outlet previously marked as the first outlet.

제3 작동 상태에서는, 배기가스 재순환이 발생하지 않도록 전형적으로 신선 공기 측으로 안내되는 밸브가 폐쇄되어 있으나, 배기가스 냉각기의 바이패스는 개방되어 있으며, 그 결과 상기 배기가스 냉각기가 우회되고, 배기가스에서 열에너지가 탈취되지 않는다.In the third operating state, the valve leading to the fresh air side is typically closed so that exhaust gas recirculation does not occur, but the bypass of the exhaust gas cooler is open, as a result of which the exhaust gas cooler is bypassed and Thermal energy is not deodorized.

바람직하게는, 언급한 모든 동작 상태는 단일 액추에이터에 의해 실현될 수 있다. 이와 관련하여, 본 발명은 하나의 유입구, 2개의 유출구 그리고 예를 들어 냉각기-바이패스(cooler-bypass)의 유입구로서 사용될 수 있는 추가 개구를 갖는 단일 밸브를 나타낸다. 이러한 경우에는 본 발명에 따른 밸브가 흐름 방향으로 냉각기 및 냉각기의 바이패스의 다음에 배치됨으로써 상기 밸브가 폐쇄된 경우 흐름 방향으로 상기 바이패스 다음에서 배기가스가 배기가스 냉각기를 통과하는 유동 경로를 선택한다. 밸브가 개방된 경우 압력 비율은 배기가스가 개방된 밸브를 통해 냉각기-바이패스로부터 유입될 정도이다. 즉, 배기가스 냉각기가 배기 시스템으로의 유동 경로와 비교하면 더 큰 유동 저항을 나타낸다.Advantageously, all the mentioned operating states can be realized by a single actuator. In this regard, the invention refers to a single valve with one inlet, two outlets and a further opening which can be used, for example, as an inlet of a cooler-bypass. In this case, the valve according to the present invention is disposed after the bypass of the cooler and the cooler in the flow direction, so that when the valve is closed, the flow path through which the exhaust gas passes through the exhaust gas cooler is selected after the bypass in the flow direction. do. When the valve is open, the pressure ratio is such that exhaust gas flows from the cooler-bypass through the open valve. That is, the exhaust gas cooler exhibits a greater flow resistance compared to the flow path to the exhaust system.

본 발명에 따른 밸브의 바람직한 개선예들은 추가 청구항들에 기재되어 있다.Preferred refinements of the valve according to the invention are described in further claims.

본 발명에 따른 밸브의 특히 간단한 설계는, 밸브 부재들이 반대 방향으로 개방 가능하고 각각의 밸브들이 마주보는 측면들 상에 탄성적으로 지지되어 있는 경우 가능해진다. 이로 인해 다른 밸브 부재가 개방되어야 하는 경우 각각 폐쇄된 밸브 부재의 전술한 "지지"가 특히 간단한 방식으로 이루어진다.A particularly simple design of the valve according to the invention is made possible if the valve members are openable in opposite directions and the respective valves are elastically supported on opposite sides. This makes the above-described "support" of each closed valve member in a particularly simple manner if the other valve members are to be opened.

유입구, 유출구들 그리고 그 사이에 배치된 밸브 부재들과 관련한 추가 개구의 규정된 배치에 있어서, 상기 유입구, 상기 제1 유출구와 상기 밸브 부재들 사이에, 하나의 밸브 부재와 상기 제2 유출구 사이에, 그리고 다른 하나의 밸브 부재와 상기 추가 개구 사이에 각각 가스 컴파트먼트(gas compartment)가 제공될 수 있다. In the defined arrangement of additional openings in relation to the inlet, outlets and valve members disposed therebetween, the inlet, between the first outlet and the valve members, between one valve member and the second outlet , And a gas compartment may be provided between the other valve member and the further opening, respectively.

밸브의 구조적 형상과 관련하여서는 밸브 디스크(valve disk) 또는 밸브 플랩(valve flap)으로서 하나 이상의 밸브 부재의 형성이 바람직하다. 밸브 디스크들의 경우, 밸브 샤프트가 병진 이동 가능하며, 그리고 상기 밸브 디스크들은 각각 개구를 가지며, 이 경우 탄성적인 지지를 위해 밸브 샤프트는 상기 개구를 통해 연장된다. 밸브 플랩들의 경우, 공통 샤프트가 전형적으로 회전 방식으로 또는 회동 방식으로 작동할 수 있다.With regard to the structural shape of the valve, it is preferable to form one or more valve members as valve disks or valve flaps. In the case of valve discs, the valve shaft is translatable, and the valve discs each have an opening, in which case the valve shaft extends through the opening for resilient support. In the case of valve flaps, the common shaft can typically operate in a rotational manner or a rotational manner.

본 발명에 따른 밸브가 단독으로 사용될 수 있더라도, 하나 이상의 상기와 같은 밸브를 구비한 배기가스 재순환(EGR) 시스템은 본 발명의 추가 대상을 형성한다.Although the valves according to the invention can be used alone, an exhaust gas recirculation (EGR) system with one or more such valves forms a further subject of the invention.

이러한 경우 이미 나타낸 바와 같이, 유입구는 내연 기관의 배기 라인에 연결되어 있고, 제1 유출구는 배기 시스템에 연결되어 있으며, 제2 유출구는 배기가스 재순환을 위해 엔진의 신선 공기 측에 연결되어 있고, 그리고 추가 개구는 냉각기-바이패스의 배출구에 연결되어 있는 것이 바람직하다. 이러한 설계를 통해서 전술한 작동 상태들이 바람직한 방식으로 나타날 수 있다.In this case, as already shown, the inlet is connected to the exhaust line of the internal combustion engine, the first outlet is connected to the exhaust system, the second outlet is connected to the fresh air side of the engine for exhaust gas recirculation, and It is preferred that the additional opening is connected to the outlet of the cooler-bypass. This design allows the above-described operating states to appear in a desirable manner.

하기에서는 본 발명의 실시예가 도면들을 참조하여 상세하게 설명된다. 도면부에서:
도 1은 본 발명에 따른 밸브를 구비한 배기가스 재순환 시스템을 도시하고;
도 2는 본 발명에 따른 밸브의 실시예를 도시하며; 그리고
도 3은 도 2에 따른 밸브의 상이한 작동 상태들을 도시한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawing:
1 shows an exhaust gas recirculation system with a valve according to the invention;
2 shows an embodiment of a valve according to the invention; And
3 shows different operating states of the valve according to FIG. 2.

도 1에 나타난 바와 같이, 내연 기관(H)으로부터는 배기 라인(A)이 한편으로는 라인(B)을 통해 배기가스 냉각기(F)로 안내되고, 다른 한편으로는 상기 냉각기(F)를 우회하는 바이패스(C)로 안내된다. 흐름 방향으로 상기 냉각기(F)와 바이패스(C) 다음에는 본 발명에 따른 밸브(G)가 위치한다. 제1 라인(D)은 밸브(G)로부터 배기 시스템으로 이어지고, 그리고 제2 라인(E)은 내연 기관(H)의 신선 공기 측으로 이어지며, 이렇게 함으로써 상기와 같은 경로를 통해 배기가스가 재순환될 수 있다.As shown in Fig. 1, from the internal combustion engine H, the exhaust line A is guided to the exhaust gas cooler F through line B on the one hand, and bypasses the cooler F on the other hand. It is guided to the bypass (C). After the cooler (F) and the bypass (C) in the flow direction, the valve G according to the present invention is located. The first line (D) leads from the valve (G) to the exhaust system, and the second line (E) leads to the fresh air side of the internal combustion engine (H), whereby the exhaust gas is recirculated through the above path. I can.

도 2에는 본 발명에 따른 밸브(G)가 세부적으로 개략적으로 도시되어 있다. 상기 밸브는, 전형적으로 내연 기관(H)의 배기 라인(A)에 연결된 유입구(1)를 갖는다. 밸브에 의해 폐쇄될 수 없는 제1 유출구(2)는 전형적으로 배기 시스템에 연결되어 있으며, 그 결과 도 2에 도시된 상태에서는 배기가스 재순환이 이루어지지 않는다. 또한, 여기서 이미 언급되어야 할 점은, 이 상태에서는 냉각기의 바이패스도 폐쇄되어 있으며, 그 결과 배기가스의 전체 열에너지가 냉각기에 의해 탈취되고, 예를 들면 객실을 가열하기 위해 사용될 수 있다. 2 schematically shows a valve G according to the invention in detail. The valve typically has an inlet 1 connected to the exhaust line A of the internal combustion engine H. The first outlet 2, which cannot be closed by means of a valve, is typically connected to the exhaust system, as a result of which there is no exhaust gas recirculation in the state shown in FIG. 2. Further, it should be mentioned here that the bypass of the cooler is also closed in this state, as a result of which the total thermal energy of the exhaust gas is deodorized by the cooler and can be used, for example, to heat the cabin.

도 2에서 알 수 있는 바와 같이, 제2 유출구(3)는 밸브 디스크(9)에 의해 폐쇄될 수 있고, 전형적으로 엔진의 신선 공기 측(E)으로 가이드되며, 그 결과 이러한 경로 상에서 배기가스 재순환이 이루어질 수 있다. 추가 개구(4)는 냉각기-바이패스(C)에 연결되어 있으며, 그러나 도 2에 도시된 바와 같이 폐쇄될 수 있다.As can be seen in Figure 2, the second outlet 3 can be closed by a valve disc 9 and is typically guided to the fresh air side E of the engine, resulting in exhaust gas recirculation on this path. This can be done. The additional opening 4 is connected to the cooler-bypass C, but can be closed as shown in FIG. 2.

도 2에서는 또한, 2개의 밸브 디스크(9, 10)가 각각 밸브 샤프트(8) 상에서 탄성적으로, 도시된 예에서는 스프링(5, 6)들에 의해 지지되어 있는 것을 알 수 있으며, 그 결과 예를 들어, 상기 스프링(6)은 "다른" 밸브 디스크(9)가 개방되면(도 3의 b 참조) 압축되며, 이와 반대의 경우(도 3의 c 참조)로도 수행된다. 도시된 예에서 스프링(5, 6)들은 또한, 초기 응력 하에 있으며, 그 결과 상기 스프링은 각각의, 개방될 밸브 디스크에서 맨 먼저 팽창된 다음, 스토퍼(11, 12)가 상기 밸브 디스크를 함께 구동하기 위해 상기 밸브 디스크의 개방(도 3의 b 및 c)을 제공한다.In Fig. 2, it can also be seen that the two valve discs 9 and 10 are elastically supported on the valve shaft 8, respectively, by the springs 5 and 6 in the illustrated example. For example, the spring 6 is compressed when the "other" valve disc 9 is opened (see Fig. 3b) and vice versa (see Fig. 3c). In the example shown, the springs 5 and 6 are also under initial stress, as a result of which the spring expands first in each of the valve discs to be opened, and then the stoppers 11 and 12 drive the valve disc together. In order to provide the opening of the valve disk (Fig. 3 b and c).

도 3의 a에서는 맨 먼저 2개의 밸브 시트가 폐쇄되어 있고, 따라서 배기가스가 배기 라인(A)으로부터 배기가스 재순환 없이 그리고 배기가스 냉각기를 우회하지 않으면서 완전히 배기 시스템(D)으로 흐르는 작동 상태가 도시되어 있다. 배기가스 냉각기는 냉각기-바이패스(C)로부터 이어지는 추가 개구(4)가 폐쇄되어 있기 때문에 우회되지 않는다.In Fig. 3A, the first two valve seats are closed, so that the exhaust gas flows completely from the exhaust line A to the exhaust system D without exhaust gas recirculation and without bypassing the exhaust gas cooler. Is shown. The exhaust gas cooler is not bypassed because the additional opening 4 leading from the cooler-bypass C is closed.

이는 도 3의 b에 도시된 작동 상태에도 적용되며, 그러나 이러한 작동 상태에서는 신선 공기 측(E)으로 가이드되는 밸브가 개방되어 있으며, 그 결과 재순환된 배기가스의 양이 조절될 수 있다. 요구 조건에 따라 그리고 배기 라인(A)과 신선 공기 측(E) 사이의 밸브 디스크(9)의 위치에 상응하게, 원하는 배기가스량이 재순환되고, 반면에 남은 배기가스는 배기 시스템(D)으로 흐른다.This also applies to the operating state shown in FIG. 3B, but in this operating state, the valve guided to the fresh air side E is open, and as a result, the amount of recirculated exhaust gas can be adjusted. Depending on the requirements and corresponding to the position of the valve disc 9 between the exhaust line A and the fresh air side E, the desired amount of exhaust gas is recirculated, while the remaining exhaust gas flows into the exhaust system D. .

도 3의 c에 도시된 예에서는 밸브(9)가 폐쇄되어 있기 때문에 배기가스 재순환이 이루어지지 않으며, 그러나 냉각기-바이패스(C)에 연결된 밸브(10)의 개방으로 인해 상기 배기가스 냉각기의 우회가 발생된다. 냉각기-바이패스(C)를 통한 유동 저항이 냉각기를 통해 가이드되는, 대안적인 유동 경로보다 적기 때문에 배기가스는 거의 100% 배기가스 냉각기 주위로 흘러 냉각되지 않은 상태로 개방된 밸브(10)를 통해 배기 시스템(D)에 이른다. In the example shown in Fig. 3C, the exhaust gas recirculation is not performed because the valve 9 is closed, but the exhaust gas cooler is bypassed due to the opening of the valve 10 connected to the cooler-bypass C. Occurs. Since the flow resistance through the cooler-bypass (C) is less than the alternative flow path, which is guided through the cooler, the exhaust gas flows around the exhaust gas cooler by almost 100% through the uncooled open valve 10. It leads to the exhaust system (D).
