Description
본 고안은 차량 엔진 흡기포트의 난류 발생장치에 관한 것이다.The present invention relates to a turbulence generator of the vehicle engine intake port.
통상, 차량 엔진을 구동시키기 위한 연료분사계통은 연료공급계와 제어계, 그리고 흡기계로 구분될 수 있다.In general, a fuel injection system for driving a vehicle engine may be divided into a fuel supply system, a control system, and an intake system.
이중 흡기계는 연료와의 외기를 혼합시키기 위한 외기 흡입계통이며, 도 1 에 도시된 바와 같이 에어크리너, 에어플로우미터, 서지탱크, 흡기매니폴드 등으로 다시 구분된다.The double intake system is an outside air intake system for mixing the outside air with fuel, and is again divided into an air cleaner, an air flow meter, a surge tank, an intake manifold, and the like as shown in FIG. 1.
이중 흡기매니폴드는 엔진과 흡기계를 연결하는 최종단계의 관으로 실린더헤드의 흡기포트의 입구와 서지탱크 사이에 결합되어 있다.The double intake manifold is the final stage connecting the engine and the intake machine and is coupled between the inlet port of the cylinder head and the surge tank.
이러한 흡기매니폴드는 기화기에서 만들어진 혼합기를 실린더로 유도하는 관이며, 2 실린더 이상의 다실린더 엔진에서는 각 실린더에 균일한 질과 량의 혼합기를 분배 역할을 하고 있다.This intake manifold is a tube that guides the mixer made in the vaporizer to the cylinder, and in a multi-cylinder engine of two or more cylinders, a uniform quality and quantity of the mixer is distributed to each cylinder.
따라서, 흡기매니폴드의 설계의 적합여부는 엔진의 체적효율과 출력을 직접적으로 큰 영향을 주는 것이다.Therefore, the suitability of the design of the intake manifold directly affects the volumetric efficiency and output of the engine.
또한, 흡기포트의 형상은 실린더 내에 송급되는 연료가스의 속도와 방향에 큰 관계가 있으며, 흡기포트의 형상에 따라 연소실 내에서의 연료가스의 연소 그 자체가 달라지게 된다.In addition, the shape of the intake port has a large relationship with the speed and direction of the fuel gas supplied into the cylinder, and the combustion of the fuel gas in the combustion chamber itself varies according to the shape of the intake port.
즉, 예시도면 도 1 에서와 같이 흡기포트(1)의 형상을 직선적으로 곧게 만들지 않고 약간 비틀어서 설계하면 피스톤의 하강에 의해 생기 흡기포트의 부압은 연료가스에 강한 맴돌이인 스윌(Swill)을 발생시킨다.That is, as shown in FIG. 1, when the shape of the intake port 1 is slightly twisted instead of being straightened, the negative pressure of the intake port generated by the lowering of the piston generates a swill, which is a strong eddy in the fuel gas. Let's do it.
그 결과로써 연료가스는 실린더 내에서 잔류하고 있던 배출가스와 혼합되어 실린더내의 연소가스 농도가 균일화 되는 것이다.As a result, the fuel gas is mixed with the exhaust gas remaining in the cylinder to uniformize the concentration of the combustion gas in the cylinder.
이는 직선적인 흡기포트는 한 번에 대량의 연료가스를 실린더 내에 송입하는 데 유효하지만 이 경우는 흡입된 연료가스 극의 일부는 연소되지 않고 배출되어 배출가스 유제측면과 엔진의 출력면에서 불합리 하기 때문이며, 따라서 이러한 비틀려져 설계된 흡기포트에 의해 배출가스의 청정화와 적은 연료로도 엔진의 출력향상을 꾀할 수 있게 된 것이다.The linear intake port is effective for feeding a large amount of fuel gas into the cylinder at one time, but in this case a part of the sucked fuel gas pole is discharged without being burned, making it unreasonable at the exhaust gas emulsion side and the engine output side. Therefore, this twisted intake port makes it possible to purify the exhaust gas and improve the engine output even with a small amount of fuel.
그러나, 흡기포트(1)가 형성하는 흡입공기의 맴돌이에도 한계가 있어 분사된 연료와 흡기가 충분히 섞여 확실한 연료가스가 형성되지 않는다는 문제점이 있었다.However, the circumference of the intake air formed by the intake port 1 also has a limitation, and there is a problem that the fuel gas is not formed by mixing the injected fuel with the intake air sufficiently.
즉, 비틀어 설계되는 흡기포트(1)는 작은 구역인 실린더 헤드에서도 점화플러그, 워터재킷, 인젝터 와의 간섭을 피해가며 형성되어야 한다는 제약을 받는다.That is, the intake port 1, which is twisted and designed, is limited in that even in the cylinder head which is a small area, it should be formed to avoid interference with the spark plug, the water jacket, and the injector.
동시에 흡기포트(1)에 의해 생성되는 맴돌이는 실린더(2)로 유입되는 순간부터 급격히 발생되며, 따라서, 흡기포트(1)내에 분사되는 연료는 흡기포트(1)에서는 충분히 흡입공기와 섞이지 않게 되는 것이다.At the same time, the eddy generated by the intake port 1 is suddenly generated from the moment it flows into the cylinder 2, so that the fuel injected into the intake port 1 is not sufficiently mixed with the intake air in the intake port 1. will be.
이에 본 고안은 상기 문제점을 해소하기 위한 차량 엔진 흡기포트의 난류 발생장치를 제공함에 그 목적이 있는 것이다.The present invention is to provide a turbulence generator of the vehicle engine intake port for solving the above problems.
이를 위한 본 고안은 흡기포트의 입구, 즉, 흡기포트와 흡기 매니폴드의 경계에 흡기포트 내에서 맴돌이를 형성하는 난류 형성 팬이 형성된 링 형상의 난류 발생장치가 설치된 것이다.The present invention for this purpose is provided with a ring-shaped turbulence generator having an inlet port, that is, a turbulence forming fan for forming a eddy in the intake port at the boundary between the intake port and the intake manifold.

이하 본 고안을 첨부된 예시도면에 의거하여 구성과 작용을 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation will be described in detail based on the accompanying drawings of the present invention.
본 고안은 엔진의 흡기포트(1)의 입구에 난류 형성링(10)이 설치되는 한편, 난류 형성링(10)은 흡기포트(1) 내주에 설치되는 지지환(12)과 중심축(14) 사이에 팬(16)이 중심축(14)으로 방사형으로 지지환(12)의 내주에 결합된 구조인 차량 엔진 흡기포트의 난류 발생장치 이다.According to the present invention, the turbulent flow forming ring 10 is installed at the inlet of the intake port 1 of the engine, while the turbulent flow forming ring 10 has the support ring 12 and the central shaft 14 installed at the inner circumference of the intake port 1. Between the fan 16 is a turbulence generator of the vehicle engine intake port is a structure coupled to the inner circumference of the support ring 12 radially to the central axis (14).
예시도면 도 2 는 본 고안에 따른 난류 형성링의 외관 설명도이고, 예시도면 도 3 은 본 고안에 따른 난류 형성링의 장착상태를 나타낸 단면 설명도이다.Exemplary drawings Figure 2 is an explanatory view of the appearance of the turbulence forming ring according to the present invention, Figure 3 is a cross-sectional view showing the mounting state of the turbulence forming ring according to the present invention.
본 고안은 흡기포트(1) 내에서 난류를 형성시키고, 이러한 난류에 인젝터(18)로 부터 연료를 분사하여 더욱 확실하게 혼합된 연료가스를 형성하여 실린더(2)로 공급되도록 하였다.The present invention forms a turbulent flow in the intake port 1, and injects fuel from the injector 18 to the turbulent flow to form a more reliably mixed fuel gas to be supplied to the cylinder 2.
즉, 흡기포트(1) 입구로 부터 난류가 형성되어, 흡기포트(1) 출구로 혼합기가 실린더로 유입될 때, 비틀어진 형상이 연료가스를 더욱 맴돌이 시키도록 된 것이다.That is, turbulence is formed from the inlet port 1 inlet, and when the mixer is introduced into the cylinder at the outlet of the inlet port 1, the twisted shape causes the fuel gas to circulate further.
이를 위한 본 고안은 흡기포트(1)의 입구에 난류 형성링(10)이 형성되며, 난류 형성링(10)은 흡기매니폴드(20)로 부터 흡기포트(1)로 유입되는 흡기에 약간의 비틀림을 주어 흡기의 이동 방향을 변경시키고 이로 인해 난류 형성링(10)을 통과한 흡기는 맴돌이를 일으키게 되는 것이다.The present invention for this purpose is a turbulent flow forming ring 10 is formed at the inlet of the intake port 1, the turbulent flow forming ring 10 is a slight intake to the intake port 1 from the intake manifold 20 into the intake port (1) It gives a twist to change the direction of movement of the intake air, which causes the intake air passing through the turbulence forming ring 10 to cause eddy.
따라서, 난류 형성링(10)에는 흡기포트(1)로 이송되는 흡기에 비틀림을 부가할 부재가 필요하며, 도시된 바와같이, 중심축(14)으로 부터 방사형으로 팬(16)이 난류 형성링(10)의 내주에 결합된 것이며, 이러한 팬(16)은 흡기에 약간의 저항으로 인한 비틀림을 부가하므로 회전될 필요는 없다.Therefore, the turbulence forming ring 10 requires a member to add torsion to the intake air transferred to the intake port 1, and as shown, the fan 16 is radially formed from the central axis 14 by the turbulence forming ring. It is coupled to the inner circumference of (10), and this fan 16 does not need to be rotated because it adds twist due to some resistance to the intake air.
따라서, 이러한 난류 형성링(10)에 의해 흡기포트(1)의 입구로 부터 흡기포트(1) 내에 맴돌이가 형성되어 흡기포트(1)에 분사되는 연료는 1차적으로 흡기포트(1) 내에서 무화되어 섞이게 되고, 2차적으로 실린더(2)로 유입되면서 흡기포트(1)의 형상에 의한 맴돌이에 의해 충분히 혼합하면서, 더욱 확실한 연료가스가 형성되는 것이다.Therefore, a circumference is formed in the intake port 1 from the inlet port 1 by the turbulence forming ring 10 so that the fuel injected into the intake port 1 is primarily in the intake port 1. It is made to atomize and mixed, and it mixes by the eddy by the shape of the intake port 1 as it flows into the cylinder 2 secondaryly, and a more reliable fuel gas is formed.
상술된 바와 같이 본 고안에 따르면 흡기포트의 입구에 난류 형성링이 설치됨으로써 실린더 내에 충분히 혼합된 연료가스가 형성되어 그 결과로써 배기가스가 경감되고, 연소 효율이 향상되는 효과가 있다.As described above, according to the present invention, the turbulence forming ring is installed at the inlet of the intake port, so that fuel gas sufficiently mixed in the cylinder is formed. As a result, the exhaust gas is reduced and the combustion efficiency is improved.
