Description
본 발명은 V형 엔진에 설치되는 가변흡기장치에 관한 것으로, 보다 상세하게는 흡기 과급시 유동저항이 발생되는 것을 방지하므로써 엔진의 토오크 향상에 기여하도록 된 V형 엔진의 가변흡기장치에 관한 것이다.The present invention relates to a variable intake apparatus installed in a V-type engine, and more particularly, to a variable intake apparatus of a V-type engine which contributes to an improvement in torque of the engine by preventing a flow resistance from occurring during intake supercharging.
최근 자동차 엔진은 고성능화 추세에 따라 흡/배기 효율을 높여 고출력을 얻도록 설계되고 있는데, 이 같은 고성능 엔진의 경우 서지탱크를 2개로 나누고 조절밸브를 매개로 서지탱크의 단면적을 가변시키므로써 흡기효율을 높여 엔진의 토오크를 향상시키는 가변흡기장치가 설치된다.Recently, automotive engines are designed to obtain high output by increasing the intake / exhaust efficiency according to the trend of high performance.In the case of such a high-performance engine, the intake efficiency is improved by dividing the surge tank into two and varying the cross-sectional area of the surge tank through a control valve. Variable intake is installed to increase the torque of the engine.
도 3은 종래 사용예에 따른 가변흡기장치를 개략 도시한 것으로, 서지탱크(30)에 개구부(32)가 형성된 격판(34)이 설치되어 이 격판(34)을 매개로 상부 서지탱크(36)와 하부 서지탱크(38)로 분할되고, 상기 개구부(32)에는 제어신호에 따라 온/오프되는 조절밸브(40)가 설치되는 구조이다.FIG. 3 schematically shows a variable intake apparatus according to a conventional use example, in which a diaphragm 34 having an opening 32 is installed in a surge tank 30, and an upper surge tank 36 is provided through the diaphragm 34. And a lower surge tank 38, and the opening 32 has a structure in which a control valve 40 is turned on / off according to a control signal.
이 같은 구조로 된 가변흡기장치는, 엔진 회전수가 중저속일 때에는 조절밸브(40)를 닫아 격판(34)을 폐쇄시키므로써 상/하부 서지탱크(36,38) 2개로 분리사용하도록 하여 기통분할에 따른 공명효과를 이용하고, 엔진의 고부하 및 고속운전시 조절밸브(40)를 열어 격판(34)을 개방시키므로써 상/하부 서지탱크(36,38)가 연통되어 흡기의 과급효과를 실현한다.In the variable intake device having such a structure, when the engine speed is medium to low speed, the control valve 40 is closed to close the diaphragm 34 so that the upper and lower surge tanks 36 and 38 can be used separately. According to the resonance effect, the upper and lower surge tanks 36 and 38 communicate with each other by opening the diaphragm 34 by opening the control valve 40 at high load and high speed operation of the engine to realize the supercharge effect of the intake air.
그러나, 이러한 가변흡기장치는, 조절밸브(40)가 닫혀있을 때에는 문제가 없으나, 고속구간에서 조절밸브(40)가 열리면 밸브체가 유로를 막아 서지탱크(30)로 유입된 고속의 공기가 조절밸브(40)와 간섭되면서 강한 와류를 발생시키게 되고, 와류로 인해 유입되는 공기의 유동을 방해하게 된다.However, this variable intake apparatus has no problem when the control valve 40 is closed, but when the control valve 40 is opened in the high speed section, the valve body blocks the flow path so that the high speed air introduced into the surge tank 30 is a control valve. Interfering with the (40) will generate a strong vortex, and hinder the flow of air due to the vortex.
이는 조절밸브가 회전형식으로 동작되기 때문에 필연적으로 발생되는 현상이고, 공기흐름을 방해하여 고속성능저하를 야기시키게 되므로 기통간 공기분배에 약 영향을 미치게 되어 에미션에도 나쁜 영향을 주게 되며, 고속의 공기가 조절밸브에 지속적으로 충격을 주게 되므로 밸브체의 내구성도 저하시키게 된다는 문제가 있다. This is inevitably occurring because the control valve is operated in a rotational type, and it impedes high speed performance by disturbing the air flow, and thus adversely affects the air distribution between the cylinders, which adversely affects emission. Since air continuously impacts the control valve, there is a problem that the durability of the valve body is also reduced.
이에 본 발명은 상기와 같은 문제를 해결하기 위한 것으로, 흡기 과급시 공기의 유로를 막아 유동저항이 발생되는 것을 최소화 하므로써 엔진 토오크를 추가적으로 향상시키는 데에 적합하게 이용할 수 있는 V형 엔진의 가변흡기장치를 제공함에 그 목적이 있다.Accordingly, the present invention is to solve the above problems, the variable intake apparatus of the V-type engine that can be suitably used to further increase the engine torque by minimizing the occurrence of flow resistance by blocking the flow path of air intake charge The purpose is to provide.
상기와 같은 목적을 달성하기 위한 본 발명 V형 엔진의 가변흡기장치는, 서지탱크가, 공기유통로를 갖춘 블록을 사이에 두고 상부서지탱브 및 하부서지탱크로 분리형성되고, 상기 블록 사이로 공기유통로와 동일수의 유통구멍이 형성된 조절플레이트가 설치되되, 이 조절플레이트는 액츄에이터를 매개로 서지탱크의 길이방향을 따라 슬라이드 이동되면서 공기유통로를 온/오프 시키도록 구성된 것을 특징으로 한다. In the variable intake device of the V-type engine of the present invention for achieving the above object, the surge tank is separated into an upper surge tank and a lower surge tank with a block having an air flow path therebetween, and the air flows between the blocks. The control plate is provided with the same number of distribution holes as the distribution path, the control plate is characterized in that configured to turn on / off the air flow path while the slide is moved along the longitudinal direction of the surge tank via the actuator.
이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 가변흡기장치의 개략도로써 상/하부 서지탱크가 분리된 상태도이고, 도 2는 본 발명에 따른 가변흡기장치의 개략도로써 상/하부 서지탱크가 연결된 상태도로써, 본 발명은 도면에 도시된 것과 같이 V6형(6기통)엔진에서 이용하는 3기통분할방식의 가변흡기장치를 예로 든 것으로, 서지탱크(1)내에 공기유통로(3)가 형성된 블록(7)이 설치되고, 상기 블록(7) 사이로 공기유통로(3)와 동일수의 유통구멍(9)이 형성된 조절플레이트(11)가 설치되며, 이 조절플레이트(11)는 액츄에이터(13)를 매개로 서지탱크(1)의 길이방향을 따라 슬라이드 이동되면서 상기 공기유통로(3)를 온/오프 시키도록 구성된다.1 is a schematic diagram of a variable intake apparatus according to the present invention is a state diagram of the upper / lower surge tank is separated, Figure 2 is a schematic diagram of a variable intake apparatus according to the present invention is a state diagram connected to the upper / lower surge tank, the present invention As shown in the drawing, the variable intake apparatus of the three-cylinder split type used in the V6 type (6-cylinder) engine is taken as an example, and the block 7 in which the air flow path 3 is formed in the surge tank 1 is installed. Between the blocks 7 is provided with an adjustment plate 11 having the same number of distribution holes 9 as the air flow path 3, the adjustment plate 11 is a surge tank (1) via the actuator (13) It is configured to turn on / off the air flow path (3) while sliding along the longitudinal direction of the).
그리고, 상기 서지탱크(1)는 블록(7)을 사이에 두고 상부서지탱브(15) 및 하부서지탱크(17)로 분리되고, 이들 상/하부 서지탱크(15,17)는 조절플레이트(11)를 매개로 연결 및 분리되는데, 이 조절플레이트(11)는 작동로드(19)를 매개로 액츄에이터(13)와 연결되어, 액츄에이터(13) 동작시 작동로드(19)가 힌지부(21)를 축으로 하여 조절플레이트(11)를 밀거나 끌어당기면서 공기유통로(3)을 열거나 닫도록 구성된다. In addition, the surge tank 1 is separated into an upper surge tank 15 and a lower surge tank 17 with a block 7 therebetween, and these upper / lower surge tanks 15 and 17 are adjustable plates ( 11) is connected and disconnected, the control plate 11 is connected to the actuator 13 via the actuating rod 19, the actuating rod 19 is hinged (21) during operation of the actuator (13) It is configured to open or close the air passage (3) while pushing or pulling the adjustment plate (11) to the axis.
이상과 같이 구성된 본 발명 가변흡기장치는, 엔진 회전수가 중저속일 때에는 액츄에이터(13)를 동작시켜 힌지부(21)를 축으로 하여 조절플레이트(11)를 밀어주면 조절플레이트(11)에 형성된 유통구멍(9)과 블록(7)에 형성된 공기유통로(3)가 겹쳐져 상부 서지탱크(15)와 하부 서지탱크(17) 2개로 분리되므로 조절플레이트(11)에 의해 압력파가 차단된다.According to the present invention, the variable intake device configured as described above has a circulation hole formed in the adjustment plate 11 by operating the actuator 13 and pushing the adjustment plate 11 with the hinge portion 21 as the axis when the engine speed is medium to low speed. (9) and the air flow path (3) formed in the block (7) is overlapped and separated into two upper surge tank 15 and the lower surge tank 17, the pressure wave is blocked by the adjustment plate (11).
그리고, 엔진의 고부하 및 고속운전시에는 액츄에이터(13)를 동작시켜 힌지부(21)를 축으로 하여 조절플레이트(11)를 끌어당기면 조절플레이트(11)에 형성된 유통구멍(9)과 블록(7)에 형성된 공기유통로(3)가 연통되면서 상부 서지탱크(15)와 하부 서지탱크(17)가 하나로 연결되어 이들 공기유통로(3)와 유통구멍(9)을 통해 압력파가 이동된다.In addition, during high load and high speed operation of the engine, the actuator 13 is operated to pull the adjusting plate 11 around the hinge portion 21, and the flow holes 9 and the block 7 formed in the adjusting plate 11 are driven.

이 같이 조절플레이트(11)를 직선방향으로 이동시키면서 서지탱크(1)를 연결 및 분할시키게 되면 고속영역에서의 흡기시 공기유동저항 없이 기통분배를 할 수 있어 에미션을 저감시킬 수 있고, 이로 인해 엔진의 토오크를 높이는 설계사양에 무리없이 적용하여 사용할 수 있다. In this way, if the surge tank 1 is connected and divided while moving the adjustment plate 11 in a linear direction, the cylinder can be distributed without air flow resistance during intake in a high speed region, thereby reducing emission. It can be easily applied to design specifications that increase the torque of the engine.
또한, 유입공기가 조절플레이트와 간섭되지 않도록 하기 때문에 공기의 충돌로 인한 소음과 내구성 저하도 효과적으로 방지할 수 있다. In addition, since the inlet air is not interfered with the adjustment plate, noise and durability degradation due to air collision can be effectively prevented.
