Description

차량 엔진 피스톤 난류 발생장치Vehicle Engine Piston Turbulence Generator

본 고안은 차량 엔진 피스톤의 난류 발생장치에 관한 것이다.The present invention relates to a turbulence generator of a vehicle engine piston.

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 1에 도시된 바와 같이 에어크리너, 에어플로우미터, 서지탱크, 흡기매니폴드 등으로 다시 구분된다.The double intake system is an outside air intake system for mixing 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 분배하는 역할을 하고 있다.The intake manifold is a tube that guides the mixer made in the vaporizer to the cylinder, and in a two-cylinder or multicylinder engine, it serves to distribute the mixer of uniform quality and quantity 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 1에서와 같이 흡기포트(1)의 형상을 직선적으로 곧게 만들지 않고 약간 비틀어서 설계하면 피스톤의 하강에 의해 생긴 흡기포트의 부압은 연료가스에 강한 맴돌이인 스월(Swil)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 caused by the lowering of the piston generates a swirl that is a strong eddy against 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.

균일화된 농도의 연료가스는 또다시 피스톤(2)의 상승에 의해 발생되는 맴돌이인 스퀴시(Squcsh)에 의해 한증 교반된 점화를 용이하게 할 수 있다.The fuel gas of uniform concentration can facilitate steam-stirred ignition by Squcsh, which is a eddy generated by the rise of the piston 2 again.

이러한 스월과 스퀴시에 의해 연료가스가 희박하여도 확실한 점화를 할 수 있게 되어 배출가스의 정정화가 건전되며, 동시에 적은 연료로 엔진의 출력이 향상되었다.These swirls and squishy make it possible to reliably ignite even when the fuel gas is lean, so that the exhaust gas is corrected and the output of the engine is improved with less fuel.

그러나, 피스톤(2) 상면의 평평한 형상으로는 확실한 스퀴시의 생성을 기대할 수 없다는 문제점이 있었다.However, there was a problem in that the formation of sure squishy cannot be expected with the flat shape of the upper surface of the piston 2.

즉, 스퀴시는 스월을 전제로하여 흡기포트(1)의 형상에 의해 생기 맴돌이인 스월에 피스톤(2)이 상승되면서 스퀴시를 일으키게 되는데, 이를 위한 피스톤(2) 상면에는 약간의 단턱만이 성형되어 있을뿐 이로 인하여 충분한 스퀴시를 얻지 못하게 되는 것이다.In other words, the squeegee is caused by the shape of the intake port (1) on the premise of the swirl, and the piston (2) is raised in the swirl, which is generated by the shape of the intake port (1) for this purpose, only a slight step on the upper surface of the piston (2) for this purpose It is only molded so that you do not get enough squishy.

이에 본 고안은 상기 문제점을 해소하기 위하여 안출된 것으로, 확실한 스퀴시를 생성하는 차량 엔진 피스톤의 난류 발생장치를 제공함에 그 목적이 있는 것이다.Accordingly, the present invention has been made to solve the above problems, and an object thereof is to provide a turbulence generator of a vehicle engine piston that generates a reliable squish.

이를 위한 본 고안은 피스톤의 상면에 다수의 난류 형성면이 반복 배열된 원뿔형상의 난류 형성판이 설치되어 피스톤의 상승시 원뿔형상과 난류 형성면이 강한 스퀴시를 일으켜 엔진의 성능이 더욱 향상되는 것이다.The present invention for this purpose is that the conical turbulence forming plate is a plurality of turbulent forming surface is repeatedly arranged on the upper surface of the piston to increase the performance of the engine by generating a strong squishy cone and turbulent forming surface when the piston rises.

14-난류 형성판16-난류 형성 곡면14- Turbulent Forming Plate 16- Turbulent Forming Surface

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 피스톤(10) 상면에 원만한 곡면부(12)를 상단으로 하는 원추형상의 난류 형성판(14)이 형성되고, 그 중심으로 부터 방사형으로 난류형성판(14)의 외주면을 따라 난류 형성 곡면(16)이 반복 배열 성형된 구조인 차량 엔진 피스톤의 난류 발생장치이다.According to the present invention, a conical turbulence forming plate 14 having a smooth curved portion 12 is formed on the upper surface of the piston 10 of the engine, and a turbulent flow is formed along the outer circumferential surface of the turbulence forming plate 14 radially from the center thereof. The curved surface 16 is a turbulence generating device for a vehicle engine piston having a structure in which it is repeatedly formed.

예시도면 도 2는 본 고안에 따른 난류 형성판의 외관 설명도이고, 예시도면 도 3은 본 고안에 따른 난류 형성판의 작용을 나타낸 단면 설명도이다.Exemplary drawings Figure 2 is an explanatory view of the appearance of the turbulence forming plate according to the present invention, Figure 3 is an explanatory cross-sectional view showing the action of the turbulence forming plate according to the present invention.

본 고안은 흡기포트에 의해 생성된 스월에 피스톤(10)이 상승되면서 강한 마찰을 일으켜 더욱 강한 스퀴시를 일으키도록 피스톤(10) 상면이 복잡한 형상으로 변경되었다.The present invention has been changed to a complicated shape of the upper surface of the piston 10 to cause a strong friction by raising the piston 10 in the swirl generated by the intake port to cause a stronger squish.

이를 위해 피스톤(10) 상면에 전체적으로 원추 형상인 난류 형성판(14)이 형성되었으며 그 상단 즉, 꼭지점에는 원만한 곡면부(12)가 형성되어, 엔진의 폭발행정시 꼭지점 부에 무리한 폭발력이 집중되는 것을 방지하였다.For this purpose, a turbulent flow forming plate 14 having a conical shape is formed on the upper surface of the piston 10, and a smooth curved portion 12 is formed at the upper end thereof, so that an excessive force of explosive force is concentrated at the vertex of the engine during the explosion stroke. To prevent it.

이러한 원뿔형상은 피스톤(10) 상승시 연료가스를 중심 상단인 곡면부(12)로 부터 외주경사를 따라 흐르도록 유도하며, 본 고안은 이러한 연료가스가 외주경사를 따라 이동되면서, 강한 맴돌이인 스퀴시가 발생되도록 난류 형성판(14)에 난류 형성면(16)이 성형되었다.This conical shape induces the fuel gas to flow along the outer circumference from the curved portion 12, which is the upper center of the piston 10, when the piston 10 rises, the present invention is moved along the outer sloping, the squish is a strong eddy The turbulent flow forming surface 16 was molded on the turbulence forming plate 14 so that.

난류 형성면(16)은 도시된 바와 같이 난류 형성판(14) 상단의 곡면부(12)로 부터 골과 마루가 난류 형성판(14)의 외주로 방사형으로 형성되며, 이러한 골과 마루는 난류 형성판(14)의 외주를 따라 반복 배열 성형된 것이다.The turbulent flow forming surface 16 is radially formed in the outer periphery of the turbulence forming plate 14 from the curved portion 12 of the top of the turbulence forming plate 14, as shown, such a valley and the turbulence It is formed by repeated molding along the outer periphery of the forming plate 14.

따라서, 피스톤(10) 상승시 연료가스는 골을 따라 흐르는 동시에 마루와 골에 마찰되면서 강한 맴돌이인 스퀴시를 일으키게 되는 것이며, 마루와 골로 이루어진 난류 형성면(16)은 상기 곡면부(12)와 같은 맥락으로 폭발행정시 폭발력의 집중을 방지하기 위해 완만한 곡면으로 형성되어 있다.Accordingly, when the piston 10 rises, the fuel gas flows along the valleys and at the same time rubs against the floors and the valleys, thereby generating a strong squish. In the same vein, it is formed with a gentle curved surface to prevent concentration of explosive power during the explosive administration.

상술된 바와 같이 본 고안에 따르면 피스톤의 상면에 원추형상의 난류 형성판이 형성되어 강한 스퀴시를 일으켜 연료가스를 충분히 혼합시켜 배출가스가 경감되고, 엔진의 출력향상 등 엔진의 성능이 향상되는 효과가 있다.As described above, according to the present invention, a conical turbulence forming plate is formed on the upper surface of the piston to generate a strong squish to sufficiently mix the fuel gas to reduce the exhaust gas, and to improve the engine performance such as improving the output of the engine. .
