Description
본 고안은 흡기포트를 통하여 연소실로 도입되는 혼합기의 와류 형성장치에 관한 것이다.The present invention relates to a vortex forming apparatus for a mixer introduced into a combustion chamber through an intake port.
가솔린 엔진은 외기와 연료를 혼합하여 실린더 내에서 연소시켜 열에너지를 회전에너지로 변환하는 기관으로 외기와 연료를 함께 실린더로 도입하기 위하여 실린더 헤더에 흡기포트가 형성되어 있다.The gasoline engine is an engine that mixes air and fuel and burns it in a cylinder to convert thermal energy into rotational energy. An intake port is formed in the cylinder header to introduce both air and fuel into the cylinder.
흡기포트의 형상은 실린더 내에 송급되는 연료가스의 속도와 방향에 큰 관계가 있으며, 흡기포트의 형상에 따라 연소실 내의 연소상태가 달라지게 된다.The shape of the intake port has a large relation to the speed and direction of the fuel gas supplied into the cylinder, and the combustion state in the combustion chamber varies according to the shape of the intake port.
극히 초기의 가솔린 엔진에서 흡기포트는 기화기에서 보내오는 연료가스를 실린더 내로 도입하기 위한 단순한 파이프에 지나지 아니하였으나, 흡기 포트가 실린더 내 연료가스의 연소에 큰 영향을 주게되고 이것이 주목되기 시작한 것은 가솔린 엔진의 배출가스가 대기오염과 밀접한 관계를 갖는다는 것이 알려지고 나서 부터이다.In very early gasoline engines, the intake port was nothing more than a simple pipe for introducing fuel gas from the carburetor into the cylinder, but the intake port had a great influence on the combustion of fuel gas in the cylinder, and this started to be noticed. Since it is known that the emission of gas is closely related to air pollution.
이와같이 배출가스의 규제를 받게된 가솔린 엔진은 일시적으로 점화시기의 조정과 밸브 타이밍을 재검토하는 등의 방법으로 규제를 해결코자 시도하였으나, 근본적인 해결은 실린더 내에서의 연료가스의 연소효율 자체를 개선하는 데 있다는 것을 깨닫게 되면서 혼합기의 고른 혼합을 위해 흡기포트 형상 설계에 관심을 갖게 되었다.The gasoline engine, which is regulated by the exhaust gas, tried to solve the regulation by temporarily adjusting the ignition timing and reviewing the valve timing, but the fundamental solution is to improve the combustion efficiency of fuel gas in the cylinder itself. As I realized that I was in the process, I was interested in designing the intake port shape for even mixing of the mixer.
즉, 흡기포트의 형상을 직선화 하지 아니하고 약간 비틀어서 설계하면 피스톤의 하강에 의해 생긴 흡기포트의 부압에 의해 연료가스에 강한 맴돌이(Swirl:와류)를 발생시키게 되며, 이결과 연료가스가 실린더 내에서 잔류하고 있는 배출가스와 혼합되어 연소가스 농도가 균일화 되므로서 연료가스가 희박하여도 확실한 점화가 가능하고 배출가스의 청정화 및 엔진출력 향상을 도모할 수 있게 되었다.In other words, if the shape of the intake port is not twisted straightly and is slightly twisted, the negative pressure of the intake port generated by the lowering of the piston generates a strong swirl in the fuel gas. By mixing with the remaining exhaust gas, the combustion gas concentration becomes uniform, so that even if the fuel gas is scarce, it is possible to reliably ignite and to clean the exhaust gas and improve the engine output.
그러나, 흡기포트의 형상은 실린더 헤드 주조와 직접적 관련성을 갖고 있어 그 설계에 있어서의 자유도가 제한되는 문제점이 있게된다.However, the shape of the intake port has a direct relationship with the cylinder head casting, and there is a problem in that the degree of freedom in design thereof is limited.
이때문에 종래 흡기포트나 흡기매니폴드에 흡기유속 및 모터구동장치나 캠축 구동연동장치등에 의해 회전하는 와류형성기를 구비토록 하는 것이 제안된 바 있었으나 엔진의 고속운전시에는 와류 형성기가 회전하는 것이 오히려 흡기저항으로 작용하여 흡기충진효율을 저하시키는 일부 단점이 지적되고 있다.For this reason, the conventional intake port or intake manifold has been proposed to have a vortex generator that rotates by an intake flow rate and a motor drive device or a camshaft drive linkage device. Some disadvantages have been pointed out that act as an intake resistance to reduce the intake filling efficiency.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로 그의 목적으로 하는 것은 엔진의 중저속 운전시에는 혼합기의 와류 형성을 촉진하고 엔진의 고속 운전시에는 혼합기의 유동특성에 방해되지 않도록 한 혼합기의 와류형성장치를 제공하는 데 있다.The present invention has been proposed in view of the above-mentioned problems, and its object is to promote vortex formation of the mixer in the medium and low speed operation of the engine, and to vortex the mixer so as not to interfere with the flow characteristics of the mixer in the high speed operation of the engine. It is to provide a forming apparatus.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도면중 부호 1 은 실린더 헤드이며, 부호 2 는 연소실에 혼합기를 도입하는 흡기포트이다.In the figure, reference numeral 1 denotes a cylinder head, and reference numeral 2 denotes an intake port for introducing a mixer into a combustion chamber.
상기 흡기포트(2)에는 회전가능하게 와류발생기(3)가 설치되며, 흡기포트(2)와 일치하는 와류발생기(3)의 내면에는 나선형의 그루우브(4,나선날개)가 형성되어 있고, 그의 외면에는 복수개의 날개(5)들이 형성되어 있다.The intake port (2) is provided with a vortex generator (3) rotatably, a spiral groove (4, spiral blade) is formed on the inner surface of the vortex generator (3) corresponding to the intake port (2), The outer surface is formed with a plurality of wings (5).
상기 와류발생기(3)의 외표면은 오일통로(6)에 노출되어 있으며, 오일통로(6)를 통해 순환하는 엔진 오일이 와류발생기(3)의 일측 날개를 치고 타측 날개측으로 돌아 나가는 것에 의해 와류발생기(3)를 회전시키게 된다.The outer surface of the vortex generator 3 is exposed to the oil passage 6, and the engine oil circulating through the oil passage 6 hits one wing of the vortex generator 3 and returns to the other wing side. The generator 3 is rotated.
상기 오일통로(6)의 도중에는 도 2 에 도시하는 것과 같이 밸브실(7)이 형성되고, 그 밸브실(7) 내에는 스프링(8)에 의해 지지되는 피스톤밸브(9)가 수용되어 있다.A valve chamber 7 is formed in the middle of the oil passage 6 as shown in FIG. 2, and a piston valve 9 supported by a spring 8 is housed in the valve chamber 7.
상기 스프링(8)의 탄발력은 엔진의 중저속 운전시의 오일압보다는 크고 엔진의 고속 운전시의 오일압보다는 작게 설정된다.The spring force of the spring 8 is set to be larger than the oil pressure in the medium and low speed operation of the engine and smaller than the oil pressure in the high speed operation of the engine.
그리고, 와류 발생기(3)는 도 1 에 도시하는 것과 같이 실린더 헤드(1)에 형성된 링형돌기(10)에 계합되어 링형돌기(10)의 안내를 따라 회전하게 되며, 그를 통해 실린더 헤드에 고정된다.Then, the vortex generator 3 is engaged with the ring-shaped protrusion 10 formed in the cylinder head 1 as shown in FIG. 1 to rotate along the guide of the ring-shaped protrusion 10 and is fixed to the cylinder head through it. .
이와같은 본 고안은 엔진의 중,저속 운전시에는 피스톤 밸브(9)에 작용하는 오일압력보다 스프링(8) 탄발력이 크므로 피스톤밸브(9)는 전진상태에 있게되며, 이 상태에서 피스톤 밸브(9) 몸체내의 연통로(11)가 오일통로(6)에 연통하여 개방하게 되며, 이에따라 엔진오일이 오일통로(6)를 통하여 와류발생기(3)를 통과하여지나가면서 날개(5)에 부딪혀 와류발생기(3)를 회전시키므로서 내면의 나선형 그루우브(4,내면날개임)가 회전하면서 흡기포트(2)를 유동하는 혼합기를 휘저어 와류를 발생시키게 된다.The present invention is such that the piston valve (9) is in the forward state because the spring 8 has a greater elastic force than the oil pressure acting on the piston valve (9) during the medium and low speed operation of the engine, the piston valve in this state (9) The communication passage 11 in the body opens and communicates with the oil passage 6, so that the engine oil hits the blade 5 while passing through the vortex generator 3 through the oil passage 6 As the vortex generator 3 is rotated, the spiral groove 4, which is an inner blade, of the inner surface is rotated to stir the mixer flowing through the intake port 2 to generate the vortex.
그러나, 엔진의 고속운전시에는 피스톤 밸브(9)에 작용하는 오일압력에 의해 피스톤밸브(9)가 스프링(8)을 압축하면서 후퇴하게 되므로서 연통로(11)가 오일통로(6)와 어긋나게 된다.However, during high speed operation of the engine, the oil pressure acting on the piston valve 9 causes the piston valve 9 to retreat while compressing the spring 8 so that the communication passage 11 is shifted from the oil passage 6. do.
이에따라 와류발생기(3)를 통과하는 엔진오일의 흐름이 일어나지 아니하게 되므로 와류발생기(3)는 회전하지 못하고 멈추어 있게 되므로서 고속으로 유동하여 도입되는 혼합기에 저항체로 작용하지 않게된다.Accordingly, since the flow of the engine oil passing through the vortex generator 3 does not occur, the vortex generator 3 does not rotate and stops, and thus does not act as a resistor to the mixer introduced by flowing at high speed.
이상과 같은 본 고안에 의하면 엔진의 운전조건에 따라 달라지는 오일압에 의해 오일통로를 개폐하는 밸브장치와, 엔진의 중저속 운전시 그 밸브장치를 통과하여 흐르는 엔진오일의 유속에 의해 회전하여 흡기포트 내부를 통과하여 유동하는 혼합기를 휘저어 와류형성을 촉진하는 와류발생기를 흡기포트에 설치하는 것에 의해서, 엔진의 중,저속 운전시 혼합기의 와류 발생을 촉진하여 완전연소에 의한 엔진출력 향상을 도모하고, 엔진의 고속운전시에는 혼합기의 빠른 공급특성을 해치지 않게 되므로서 엔진성능을 향상시키게 되는 효과가 있다.According to the present invention as described above, the valve device for opening and closing the oil passage by the oil pressure varying according to the operating conditions of the engine, and the intake port is rotated by the flow rate of the engine oil flowing through the valve device during the low to medium speed operation of the engine By installing a vortex generator in the intake port that stirs the mixer flowing through the inside to promote vortex formation, it promotes vortex generation of the mixer during medium and low speed operation of the engine, and improves engine output by complete combustion. When the engine is running at high speed, the fast feed characteristics of the mixer are not impaired, thereby improving the engine performance.
