본 발명은 차량의 흡기매니폴드에 관한 것으로, 특히 저속 및 중속주행시 흡기관성을 최대한 향상시키는 동시에 흡기부압을 높이도록 중, 저속주행시에는 외측통로의 길이를 길게하고 면적을 크게하며, 고속주행시 흡입저항을 최대한 줄이도록 내, 외측통로의 길이를 짧게 하고 면적을 크게하여 저속 및 중속주행시 흡입효율을 향상시켜 엔진성능을 높이는 동시에 고속주행시 최고출력을 크게 높이도록 한 차량의 가변흡기장치에 관한 것이다.The present invention relates to an intake manifold of a vehicle, and in particular, to increase the intake pipe pressure as much as possible at high speeds and low speeds, and to increase the intake negative pressure. The present invention relates to a variable intake apparatus of a vehicle in which the length of the inner and outer passages is shortened and the area is increased so as to reduce the maximum, and the suction efficiency is improved at low speed and medium speed driving, thereby improving the engine performance and increasing the maximum power at high speed driving.
종래 차량의 가변흡기장치는 제4도와 같이, 서지탱크(10')와 연결된 흡기매니폴드(20')내의 중간부에 격벽(23')을 설치하여 내, 외측통로(21')(22')가 형성되게 하고, 그 격벽(23')의 내측통로(21')의 출구에 전자제어부의 신호를 받아서 별도의 개폐수단에 의하여 개폐되는 스로틀밸브(30')가 설치되어 있다.In the conventional vehicle variable intake apparatus, as shown in FIG. 4, the partition wall 23 'is installed in the middle portion of the intake manifold 20' connected to the surge tank 10 'to allow the inner and outer passages 21' and 22 '. ) Is formed, and a throttle valve 30 'is provided at the outlet of the inner passage 21' of the partition 23 'to receive the signal of the electronic control unit and to be opened and closed by a separate opening and closing means.
이때 가변 흡기구조는, 저속시에는 제5도(a)와 같이 통로가 짧을 경우에는 공기의 이동운동을 계thr하려는 관성력이 작고, (b)와 같이 통로가 긴 경우에는 공기질량에 비례하여 관성력이 크기 때문에 스로틀밸브의 개폐로 인한 압력파의 영향보다 관성력에 의한 흡입력이 공기 흡입량을 좌, 우하게 됨을 알 수 있으므로 저속시에는 통로가 길어야 하고, 고속시에는 제6도(a)와 같이 통로가 짧아야 스로틀밸브의 고속 개폐로 인한 압력파의 영향이 작고, (b)와 같이 통로가 긴 경우에는 스로틀밸브의 고속 개폐로 인한 압력파에 의하여 흡기가 잘되지 않음을 알 수 있어, 압력파의 영향이 관성력보다 크게 나타남을 알 수 있으므로 고속시에는 통로가 짧아야 된다.At this time, the variable intake structure has a small inertial force to measure the movement of air when the passage is short at low speed as shown in FIG. 5 (a), and an inertial force proportional to the air mass when the passage is long as shown in (b). Because of this size, it can be seen that the suction force due to inertia forces the air suction amount to the left and right rather than the influence of the pressure wave due to the opening and closing of the throttle valve. Therefore, the passage should be long at low speed, and the passage as shown in FIG. It should be noted that the shortness of the pressure wave due to the high speed opening and closing of the throttle valve is small, and when the passage is long as shown in (b), it is understood that the intake is not good due to the pressure wave due to the high speed opening and closing of the throttle valve. It can be seen that the effect is larger than the inertia force, so the passage should be short at high speed.
따라서, 내, 외측통로(21')(22')는 유선형으로 형성하여 외측통로(22')는 중, 저속주행시 제4도(a)와 같이 공기의 이동거리를 길게 하고 면적을 작게 하여 공기의 관성흐름을 최대한 활용하도록 하고, 고속주행시에는 제4도(b)와 같이 내측통로(21')의 스로틀밸브(30')를 개방시켜 공기의 이동거리를 짧게하고 면적을 크게 하여 내, 외측통로(21')(22')로 동시에 공기를 안내하여 흡기맥동의 발생으로 인한 실제 흡입 공기량부족을 방지하도록 하였다.Therefore, the inner and outer passages 21 'and 22' are formed in a streamlined shape, and the outer passage 22 'has a long air moving distance and a small area as shown in FIG. In order to make the best use of the inertia flow, and when driving at high speed, as shown in FIG. 4 (b), the throttle valve 30 'of the inner passage 21' is opened to shorten the air moving distance and increase the area. At the same time, the air is guided to the passages 21 'and 22' to prevent the actual intake air shortage due to the intake pulsation.
그러나 상술한 흡기매니폴드(20')는 내, 외측통로(21')(22')의 형성을 위하여 중간부에 격벽(23')을 설치하여야 되므로 제작 및 가공이 어려워 원가의 상승원인이 되었고, 저속주행시 내측통로(21')를 폐쇄시켜야 하므로 흡입효율이 낮으며, 공기의 흡입시 단순히 내, 외측통로(21')(22')를 따라 안내되므로 와류의 형성이 미미하여 오히려 층류로 형성되므로 연소효율이 저하되어 출력이 떨어지는 문제점이 있었다.However, the above-described intake manifold 20 'has to be provided with a partition 23' in the middle part in order to form the inner and outer passages 21 'and 22'. The suction efficiency is low because the inner passage 21 'must be closed when driving at low speed, and since the air is simply guided along the inner and outer passages 21' and 22 'when the air is sucked, the vortex is not formed so that the laminar flow is formed. There was a problem that the output efficiency is lowered because the combustion efficiency is lowered.
본 발명은 이러한 종래의 문제점을 해결하고자 하는 것으로, 저속 및 중속주행시 흡기관성을 최대한 향상시키는 동시에 흡기부압을 높이도록 중, 저속주행시에는 외측통로의 길이를 길게하고 면적을 크게하며, 고속주행시 흡입저항을 최대한 줄이도록 내, 외측통로의 길이를 짧게 하고 면적을 크게하여 저속 및 중속주행시 흡입효율을 향상시켜 엔진성능을 높이는 동시에 고속주행시 최고출력을 크게 높이고자 차량의 가변흡기장치를 제공하는 데 그 목적이 있다.The present invention is to solve such a conventional problem, to increase the intake pipe pressure at the low speed and medium speed as much as possible at the same time to increase the intake negative pressure during the medium and low speed, the length of the outer passage to increase the area, the suction resistance during high speed The purpose of the present invention is to provide a variable intake device of a vehicle to shorten the length of the inner and outer passages and to increase the area to improve the suction efficiency at low speed and medium speed driving, to increase the engine performance and to increase the maximum power at the high speed driving. There is this.
본 발명은 이러한 목적을 달성하기 위하여, 흡입되는 공기를 일시적으로 저장하여 각 흡기매니폴드로 배분하는 서지탱크와, 저속 및 중속주행시에는 외측통로의 길이를 길게하고 면적을 크게하며 고속주행시에는 내, 외측통로의 길이를 짧게 하고 면적을 크게 하도록 흡기매니폴드의 중간부에 설치되어 상단을 중심으로 회동되는 길이가 긴 유선형의 밸브날개와, 밸브날개의 가느다란 자유단에 연결하여 전자제어부의 신호를 받아 내측통로를 저속주행시에는 차단하고 고속주행시에는 개방하도록 작동하는 가변밸브조정기와, 내, 외측통로와 연통되어 각 실린더의 연소실로 공기와 연료의 혼합기를 공급하도록 흡입밸브가 설치된 흡기포트로 차량의 가변흡기장치를 구성한 것이 본 발명의 기본적인 특징이다.In order to achieve the above object, the present invention provides a surge tank for temporarily storing the intake air and distributing it to each intake manifold, and for the low speed and medium speed driving, the length of the outer passage is increased and the area is increased. It is installed in the middle part of the intake manifold so as to shorten the length of the outer passage and increase the area, and connects the long streamlined valve blade that rotates around the upper end and the thin free end of the valve blade to connect the signal of the electronic control unit. Variable valve regulator that operates to block the inner passage at low speed and to open at high speed, and the intake port installed with the intake valve installed to communicate air and fuel to the combustion chamber of each cylinder. The configuration of the variable intake apparatus is a basic feature of the present invention.

이하 본 발명을 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도면 제1도 및 제2도는 본 발명의 실시예로서, 흡입되는 공기를 일시적으로 저장하여 각 흡기매니폴드(20)로 배분하는 서지탱크(10)와, 저속 및 중속주행시에는 외측통로(22)의 길이를 길게하고 면적을 크게하며 고속주행시에는 내, 외측통로(21)(22)의 길이를 짧게 하고 면적을 크게 하도록 흡기매니폴드(20)의 중간부에 설치되어 상단을 중심으로 회동되는 길이가 긴 유선형의 밸브날개(30)와, 밸브날개(30)의 가느다란 자유단에 연결하여 전자제어부(40)의 신호를 받아 내측통로(21)를 저속주행시에는 차단하고 고속주행시에는 개방하도록 작동하는 가변밸브조정기(50)와, 내, 외측통로(21)(22)와 연통되어 각 실린더(60)의 연소실(61)로 공기와 연료의 혼합기를 공급하도록 흡입밸브(70)가 설치된 흡기포트(62)로 차량의 가변흡기장치를 구성한다.1 and 2 are embodiments of the present invention, a surge tank 10 for temporarily storing inhaled air and distributing it to each intake manifold 20, and an outer passage 22 at low and medium speed driving. Length of the inlet manifold 20 is rotated about the upper end of the intake manifold 20 so as to shorten the length of the inner and outer passages 21 and 22 and increase the area during high-speed driving. Is connected to the long streamline valve wing 30 and the thin free end of the valve wing 30 to block the inner passage 21 at low speed and open at high speed by receiving the signal from the electronic control unit 40. Intake port 70 is provided in communication with the variable valve regulator 50 and the inner and outer passages 21 and 22 to supply a mixture of air and fuel to the combustion chamber 61 of each cylinder 60. 62, a variable intake apparatus of a vehicle is constituted.
상기 흡기매니폴드(20)의 내측통로(21)측 하부에 저속 및 고속주행시 흡입되는 공기의 와류가 생성되도록 형성되는 달팽이형의 와류실(23)을 구성한다.A snail-shaped vortex chamber 23 is formed in the lower portion of the inner passage 21 side of the intake manifold 20 so as to generate vortices of air sucked at low and high speed driving.
상기 밸브날개(30)는 상단을 흡기매니폴드(20)에 굴대설치하도록 회전축(31)을 설치하여 설정된 각도로 요동되게 한다.The valve blade 30 is oscillated at a set angle by installing a rotary shaft 31 so as to mandulate the upper end to the intake manifold 20.
상기 가변밸브조정기(50)는 밸브날개(30)의 자유단에 밀고 잡아당기기 용이한 와이어(51)로 연결한다.The variable valve regulator 50 is connected to the free end of the valve blade 30 by a wire 51 that is easy to push and pull.
상기 각 실린더(60)에는 혼합기의 점화를 위하여 스파크플러그(80)를 설치하며, 연소된 배기가스의 배기를 위하여 배기밸브(90) 및 배기포트(63)가 형성되어 있고, 혼합기의 흡입, 압축, 폭발, 배기를 위하여 왕복 운동하는 피스톤(100)이 설치되어 있다.Each cylinder 60 is provided with a spark plug 80 for ignition of the mixer, and an exhaust valve 90 and an exhaust port 63 are formed for exhausting the combusted exhaust gas. Piston 100 is installed to reciprocate for explosion, exhaust.
이와같이 구성된 본 발명은, 각 실린더(60)의 4싸이클행정은 일반 엔진의 작동원리와 동일하므로 이에 대한 상세한 설명은 생략하고, 다만 본 발명의 특징에 대해서만 설명하기로 한다.In the present invention configured as described above, since the four cycle stroke of each cylinder 60 is the same as the operation principle of the general engine, a detailed description thereof will be omitted, and only the features of the present invention will be described.
차량의 저속 및 중속주행시 전자제어부(40)는 가변밸브조정기(50)를 작동시켜 와이어(51)를 통하여 밸브날개(30)의 자유단을 밀어서 제1도의 가상선과 같이 밸브날개(30)의 이동으로 흡기매니폴드(20)의 내측통로(21)를 차단되도록 하며, 서지탱크(10)에 의하여 분배되는 공기는 길이가 긴 외측통로(22)를 통하여 흡입안내되고, 외측통로(22)로 흡입안내되던 공기는 와류실(23)부근으로 가면서 면적이 점차적으로 넓어지게 되어 흡기관성을 최대한 향상시키는 동시에 흡기부압을 높이게 되며, 그 후 외측통로(22)의 형상에 의하여 흡입되는 공기는 자연스럽게 와류실(23)로 안내되어 와류가 생성되도록 하는 것이다.During the low and medium speed driving of the vehicle, the electronic control unit 40 operates the variable valve regulator 50 to push the free end of the valve blade 30 through the wire 51 to move the valve blade 30 as shown in FIG. The inner passage 21 of the intake manifold 20 is blocked, and the air distributed by the surge tank 10 is suction guided through the long outer passage 22 and sucked into the outer passage 22. The guided air gradually increases in area as it approaches the vortex chamber 23, thereby improving the intake pipe maximally and increasing the intake negative pressure. Then, the air sucked by the shape of the outer passage 22 naturally vortex chamber. Guided to (23) is to cause the vortex to be generated.
즉, 와류실(23)은 달팽이형으로 형성하여 흡입되는 공기를 자연스럽게 회전되도록 와류를 생성시키게 되는 것이다.That is, the vortex chamber 23 is formed in a snail shape to generate a vortex to naturally rotate the sucked air.
와류실(23)을 통과한 공기는 분사되는 연료와의 혼합시 균일하게 혼합되어 분무화된 뒤 개방된 흡기포트(62)를 통하여 실린더(60)의 연소실(61)로 공급되는 것이다.Air passing through the vortex chamber 23 is uniformly mixed and sprayed upon mixing with the injected fuel, and then supplied to the combustion chamber 61 of the cylinder 60 through the open intake port 62.
그리고, 차량의 고속주행시 전자제어부(40)가 가변밸브조정기(50)를 작동시켜 와이어(51)를 통하여 밸브날개(30)의 자유단을 잡아 당겨서 제1도의 실선과 같이 밸브날개(30)의 이동으로 흡기매니폴드(20)의 내, 외측통로(21)(22)를 동시에 개방되도록 하며, 서지탱크(10)에 의하여 분배되는 공기는 길이가 긴 외측통로(22)와 길이가 짧은 내측통로(21)를 통하여 동시에 흡입안내되어 흡기맥동으로 인한 흡입공기량의 감소를 방지하고, 내, 외측통로(21)(22)로 흡입안내되는 각 공기의 일부는 흡기포트(62)로 안내되고 나머지의 일부는 자연스럽게 와류실(23)로 안내되어 와류가 생성되도록 하는 것이다. 특히 유선형의 밸브날개(30)는 저속, 중속 및 고속주행시의 통로를 가변시킬 뿐만 아니라 공기의 저항을 최소화시키고, 중립시 가느다란 날개끝단인 자유단에서 내, 외측통로(21)(22)에서 유입되는 공기를 더욱 와류가 생성되도록 촉진하게 된다.In addition, the electronic control unit 40 operates the variable valve regulator 50 during the high-speed driving of the vehicle to pull the free end of the valve wing 30 through the wire 51, so that the valve wing 30 of FIG. The inner and outer passages 21 and 22 of the intake manifold 20 are simultaneously opened by movement, and the air distributed by the surge tank 10 has a long outer passage 22 and a short inner passage. At the same time through the suction guide (21) to prevent a decrease in the amount of intake air due to the intake pulsation, a portion of each air guided to the inner and outer passages (21, 22) is guided to the intake port 62 and the remaining Some are naturally guided to the vortex chamber 23 to produce vortices. In particular, the streamlined valve wing 30 not only varies the passages at low speed, medium speed and high speed, but also minimizes the resistance of the air, and at the free end, which is a thin blade tip at the time of neutral, at the inner and outer passages 21 and 22. The incoming air is further promoted to produce vortices.
따라서 흡기매니폴드(20)의 내, 외측통로(21)(22)를 최대한 이용하여 흡기효율을 높이고 흡기저항을 줄이도록 하는 동시에 밸브날개(30)의 형상과 와류실(23)에 의하여 공기의 와류효과를 촉진시켜주므로 균일한 혼합기의 유지로 고효율 및 고출력을 낼 수 있는 것이다.Therefore, by utilizing the inner and outer passages 21 and 22 of the intake manifold 20 to maximize the intake efficiency and reducing the intake resistance, the shape of the valve wing 30 and the vortex chamber 23 Since it promotes the eddy current effect, high efficiency and high output can be achieved by maintaining a uniform mixer.
제3도는 엔진의 회전수와 출력에 대한 그래프로서, 저속주행시와 고속주행시에 넓은 영역에서 최대의 토오크 및 출력을 얻을 수 있음을 알 수 있다.3 is a graph of the rotational speed and the output of the engine, and it can be seen that the maximum torque and output can be obtained in a wide area at low speed and at high speed.
또한, 흡기매니폴드(20)에 유선형의 밸브날개(30)를 설치하여 내, 외측통로(21)(22)가 형성되도록 하는 동시에 가변되도록 하므로서 제작 및 가공이 매우 용이하여 원가절감에도 도움을 줄 수가 있는 것이다.In addition, by installing the streamlined valve blades 30 in the intake manifold 20 to allow the inner and outer passages 21 and 22 to be formed and variable at the same time, it is very easy to manufacture and process, thus helping to reduce costs. There is a number.
이와같이 본 발명은 저속 및 중속주행시 흡기관성을 최대한 향상시키는 동시에 흡기부압을 높이도록 중, 저속주행시에는 외측통로의 길이를 길게하고 면적을 크게하며, 고속주행시 흡입저항을 최대한 줄이도록 내, 외측통로의 길이를 짧게 하고 면적을 크게하여 주므로서 저속 및 중속주행시 흡입효율을 향상시켜 엔진성능을 높이는 동시에 고속주행시 최고출력을 크게 높일 수 있는 효과가 있다.As described above, the present invention increases the length of the outer passage and increases the area of the inner and outer passages in order to increase the intake pipe pressure at the low speed and the medium speed as much as possible and to increase the intake negative pressure during the low speed driving. By shortening the length and increasing the area, it is possible to improve the engine performance by improving the suction efficiency at low speed and medium speed driving, and to increase the maximum power at high speed driving.
