Description
본 고안은 실린더내에 유입되는 혼합가스의 와류 형성을 유도하는 유동가이더에 관한 것이다.The present invention relates to a flow guider for inducing vortex formation of a mixed gas introduced into a cylinder.
연소효율은 일반적으로 실린더내에 도입된 혼합가스가 얼마나 고르게 잘 혼합되었는가에 크게 영향을 미치게 되므로 혼합가스의 와류 형성을 유도하기 위하여 흡기포트를 나선형으로 형성하거나 또는 피스톤에 보울형 연소실을 형성하는 등 및 실린더헤드를 연소실 측으로 돌출시켜 피스톤 압축시 스퀴쉬 효과를 얻기 위한 스퀴쉬 영역을 두는 등 여러가지 방안이 제안되어 현재 사용중에 있다.Combustion efficiency generally affects how evenly the mixed gas introduced into the cylinder is mixed well, so that the intake port is spirally formed or the bowl-type combustion chamber is formed on the piston to induce vortex formation of the mixed gas, and the like. Various methods have been proposed and are currently in use such as protruding the cylinder head toward the combustion chamber to provide a squish area for obtaining the squish effect when compressing the piston.
그러나 상기한 방식들은 실린더헤드의 형상을 매우 복잡하게 만들므로 그 효과를 얻기위한 가공작업으로 비용이 크게 증대되는 문제점이 있게 된다.However, the above-described methods make the shape of the cylinder head very complicated, and therefore, there is a problem in that the cost is greatly increased in the machining operation to obtain the effect.
이에 본 고안은 상기한 점을 감안하여 제안된 것으로서 그의 목적으로 하는 것은 실린더블록과 실린더헤드 사이에 가스켓 장착 공간에 삽입하여 흡기포트를 통해 실린더내로 도입되는 혼합가스의 유동을 차단하거나 방향을 바꾸어 강한 와류 형성을 유도하는 유동가이더를 제공하는 데 있다.The present invention has been proposed in view of the above point, and its purpose is to insert into the gasket mounting space between the cylinder block and the cylinder head to block or redirect the flow of mixed gas introduced into the cylinder through the intake port. It is to provide a flow guider to induce vortex formation.
상기한 목적을 달성하기 위하여 본 고안은 실린더블록과 실린더헤드가 체결되는 경계부에 가스켓 내측으로 삽입되는 링부와; 상기 링부의 일측으로부터 흡기포트의 밸브시트부 외주를 감싸도록 중앙부로 돌출하는 차단부: 로 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention includes a ring portion inserted into the gasket at the boundary portion between the cylinder block and the cylinder head; Blocking part protruding toward the center portion to surround the outer periphery of the valve seat portion of the intake port from one side of the ring portion.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
제1도는 본 고안의 와류 형성을 유도하는 유동가이더를 나타내는 평면도이며 제2도는 본 고안이 장착된 상태의 엔진의 정단면도이다.1 is a plan view showing a flow guide to induce vortex formation of the present invention, and FIG. 2 is a front sectional view of an engine in which the present invention is mounted.
도면중 부호 1은 본 고안의 유동가이더로서 링부(2)와 링부(2)로부터 중앙으로 돌출된 차단부(3)로 구성되어 있다.Reference numeral 1 in the figure is a flow guide of the present invention is composed of a ring portion 2 and a blocking portion 3 protruding from the ring portion 2 to the center.
상기 링부(2)는 실린더블록(4)과 실린더헤드(5)의 체결시 가스켓(6) 안쪽으로 개재되어 체결되며 상기 차단부(3)는 실린더보어(7)의 중앙으로 돌출한다.The ring part 2 is interposed into the gasket 6 when the cylinder block 4 and the cylinder head 5 are fastened, and the blocking part 3 protrudes toward the center of the cylinder bore 7.
이와같이 돌출된 차단부(3)는 흡기포트(8) 끝단의 밸브시트부(9)의 일측 외주를 감싸도록 호형 측면(10)을 갖는다.The blocking part 3 protruding in this way has an arc-shaped side surface 10 so as to surround one outer circumference of the valve seat part 9 at the end of the intake port 8.
이에따라 흡기포트(8)를 통해 연소실로 유입되는 혼합가스가 차단부(3)가 없는 빈공간(11) 측으로 화살표와 같이 유동이 안내되어져 유동성이 강해지고 실린더내 와류의 대칭성이 향상되어 고체유동(Solidbody Rotation)에 가깝게 되고 또한 와류의 중심이 실린더 보어 중앙에 가깝게 된다.Accordingly, the mixed gas flowing into the combustion chamber through the intake port 8 is guided as shown by the arrow toward the empty space 11 without the blocking portion 3, so that the fluidity is increased and the symmetry of the vortex in the cylinder is improved, thereby improving the solid flow ( And the center of the vortex is close to the center of the cylinder bore.
상기 유동가이더(1)의 차단부(3)의 형상은 정상류 와류 측정기를 통해 최적 형상으로 설계하게 된다.The shape of the blocking part 3 of the flow guider 1 is designed to an optimum shape through the steady flow vortex measuring device.
이상과 같은 본 고안은 실리너내에 도입되는 혼합가스의 유동을 특성 방향으로 안내하여 와류 형성을 촉진하는 유동가이더를 실린더블록과 실린더헤드 사이의 체결 경계부에 가스켓과 함께 삽입시켜 와류를 형성하기가 용이한 강한 유동 특성을 가져오게 되므로써 엔진 성능을 향상하고 배기가스를 저감하는 동시에 보조가스켓의 역할을 수행하여 오일의 실린더내 유입을 방지하는 효과가 있게 된다.The present invention as described above is easy to form a vortex by inserting a flow guider for vortex formation by guiding the flow of the mixed gas introduced into the cylinder in the characteristic direction together with the gasket at the fastening boundary between the cylinder block and the cylinder head. By bringing a strong flow characteristics it is possible to improve the engine performance, reduce the exhaust gas and at the same time act as an auxiliary gasket to prevent the inflow of oil into the cylinder.
