Description

상하 흡배기 4행정 엔진{omitted}Top and bottom four-stroke engines

본발명은 4행정엔진의 흡배기구를 실린더의 상,하부에 만들어 4행정엔진의 흡입량과 배기량을 늘려 엔진의 효율을 높이기 위한 기술에 관한것이다 The present invention relates to a technology for increasing the efficiency of the engine by increasing the intake and exhaust of the four-stroke engine by making the four-stroke engine intake and exhaust mechanisms at the top and bottom of the cylinder.

일반적으로 4행정엔진 들은 2001년 6월 25일자로 공개된 대한민국 공개특허 2001-0051464호에서 4 행정 디젤 엔진의 단면도로 나타낸 도면 1에 개시된 바와 같이 흡입구와 배기구를 엔진상부에 하나씩 가지고 있거나 혹은 흡기와 배기의 효율을 높이고자 두 개이상의 흡배기구를 엔진상부에 구성하는 것이 일반적이다.In general, four-stroke engines have one inlet and one exhaust in the upper part of the engine, as shown in FIG. 1 of the four-stroke diesel engine in Korean Patent Publication No. 2001-0051464 published on June 25, 2001, It is common to provide two or more intake and exhaust vents on top of the engine to increase the efficiency of the exhaust.

본발명은 상기 배경기술에서와 같이 엔진의 상부에만 배기구를 구성한 기존의 4행정 엔진은 폭발행정에서 피스톤이 하강하면서 피스톤이 최하부에 돌입하기 직전 상부의 배기구가 열리면서 배기행정이 시작되어 피스톤이 하행정에서 상부행정으로 돌아 완전상승하면서 배기 행정은 끝난다 According to the present invention, as in the background art, the existing four-stroke engine that has an exhaust port formed only at the upper part of the engine, the piston is lowered in the explosion stroke and the exhaust stroke of the upper part is opened immediately before the piston enters the lowermost part. Exhaust stroke is completed as we go back to upper administration

그런데 상기의 배기과정에서 상승하는 피스톤은 실린더내에 고압상태로 남아있는 배기가스를 밀어내기 위하여 일정부분의 힘을 낭비할 수밖에 없었다However, the piston rising in the exhaust process was forced to waste a certain amount of force to push the exhaust gas remaining in the high pressure state in the cylinder.

또한 터보 차져를 부착 한경우에는 피스톤이 밀어내야 하는 배기압이 상승할수밖에 없음으로 인하여 저알피엠에서는 오히려 터보차져가 부작용을 유발하는 상황까지 발생하는것이 일반적이었으며 , In addition, when the turbocharger is attached, the exhaust pressure that the piston must push out increases, so it is common that the turbocharger causes a side effect at low RPM.

흡입행정에서 또한 상층부에 1개혹은 2개이상으로 구성된 흡입구만으로는 충분한 공기를 흡입하기에 부족함이 있었다 그로인하여 고압으로 연료와 공기를 밀어넣는 방식이 사용되기도 한다In the intake stroke, one or two intakes in the upper part alone were not enough to intake enough air. Therefore, the method of pushing fuel and air at high pressure is also used.

그럼에도 고알피엠에서의 충분한 공기를 흡입하는데에 있어서는 부족한 과제를 지닐수밖에 없었다 .Nevertheless, it was inadequate to intake sufficient air in high-RPM.

본발명은 상기와 같은 종래의 4 행정 엔진들이 상부에만 흡입구와 배기구를 구성한것과는 달리 본발명은 4행정 엔진의 상부와 하부 두곳에 흡입구와 배기구를 구성함으로써 종래의 4행정 엔진들이 공통적으로 가지는 흡입과 배기에관한 상기와 같은 과제들을 해결하고자 한것이다 The present invention is different from the conventional four-stroke engines such as the inlet and exhaust in the upper portion of the four-stroke engine, the present invention is composed of the intake and exhaust in two upper and lower portions of the four-stroke engine and the conventional four-stroke engines It is to solve the above problems related to exhaust.

본발명은 4행정 엔진의 상부와 하부 두곳에 흡입구와 배기구를 구성함으로써 종래의 4행정엔진들이 공통적으로 가지는 흡입과 배기에관한 상기와 같은 과제에 있어서 다음과 같은 효과를 가지게 된다 The present invention has the following effects on the intake and exhaust of common four-stroke engines by forming inlet and exhaust ports at the top and bottom of the four-stroke engine.

먼저 흡입과정에 있어서, 본발명은 종래의 4행정엔진 흡입과정과 동일한구성을 유지하면서 엔진의 실린더 하부에 흡입구를 추가로 구성함으로써 종래의 4행정엔진이 엔진상부에 구성된 흡입구로 충분히 흡입을 못하여 엔진 내부가 순간 저압상태가 되면 피스톤이 최종 하사점에 도달할때즘 실린더 하부에 구성된 하부의 흡입구가 자동으로 열리면서 외부의 공기가 밀려들어와 순간 엔진내부의 저압을 보강 해주게되어 결과적으로 부족한 공기를 보충 하게하여 엔진의 효율을 높여주는 효과를 가지게된다 First, in the intake process, the present invention maintains the same configuration as the conventional four-stroke engine intake process, and additionally configures the inlet in the lower part of the cylinder of the engine, so that the conventional four-stroke engine cannot sufficiently inhale the intake port formed in the upper part of the engine. When the internal low pressure is reached, the lower inlet of the cylinder is automatically opened when the piston reaches the bottom dead center, and the external air is pushed in to reinforce the low pressure inside the engine. It will have the effect of increasing the efficiency of the engine

다음은 배기과정에 있어서,Next, in the exhaust process,

본발명은 상기 와 같이 종래의 4행정 엔진의 엔진상부에 구성된 흡입구과 배기구의 구성을 모두 유지하면서 엔진의 실린더 하부에 배출구를 추가하여 구성함으로써 종래의 4행정엔진이 상부에 구성된 배기구로 고압의 배출가스를 배출하는 동시에 하부에 추가로 구성된 배기구로 추가로 배기함으로써 종래의 4행정엔진의 배기압을 낮추어주게된다 따라서 종래의 4행정엔진이 배기를 위한 피스톤 상승 행정에서의 배기압 저항을 감소시켜주어 결과적으로 엔진의 효율을 높여주는 효과를 가지게되며 아울러 엔진하부에 추가된 하부 배기구로의 배출은 엔진 피스톤 상승과는 무관하게 배출됨으로써 본발명에서 추가한 엔진하부의 배기구로 배출되는 배기가스압은 종래의 4행정엔진배기와는 달리 저알피엠에서도 엔진효율에 지장없는 터보차져의 활용을 가능하게 할수있는 효과를 가지게 된다 The present invention is configured to add a discharge port to the lower cylinder of the engine while maintaining both the inlet and exhaust ports configured in the engine upper portion of the conventional four-stroke engine as described above, the conventional four-stroke engine exhaust gas of the high pressure to the exhaust port formed on the upper The exhaust pressure of the conventional four-stroke engine is lowered by exhausting additional gas through the exhaust port further configured at the same time. Therefore, the conventional four-stroke engine reduces the exhaust pressure resistance in the piston upstroke for exhausting. In addition, the exhaust gas is discharged to the lower exhaust port added to the lower part of the engine. Unlike the administration engine exhaust, the turbocharger does not affect engine efficiency even at low RPM. Will have the effect of enabling

종래의 4행정 엔진들이 상부에만 흡입구와 배기구를 구성한것과는 달리 본발명은 4행정 엔진의 상부와 4행정 엔진의 하부에 흡배기구를 구성하였다Unlike the conventional four-stroke engines having intake and exhaust ports only at the top, the present invention has an intake and exhaust at the top of the four-stroke engine and the bottom of the four-stroke engine.

첨부된 도면을 참조하여 본발명을 설명하면 다음과 같다 Hereinafter, the present invention will be described with reference to the accompanying drawings.

먼저 (도 1,2 참조) 종래의 4행정 엔진의 실린더(70)의 하부 일면에 하부배기구(12)을 (도,5참조) 구성한다 그다음 그 외면에는 스프링(11)과 내부 배기압으로 닫히고 열리는 여닫이 판(10) 이 구성되고 First (see FIGS. 1 and 2), the lower exhaust pipe 12 (see FIG. 5) is formed on one lower surface of the cylinder 70 of the conventional four-stroke engine. Then, the outer surface is closed by the spring 11 and the internal exhaust pressure. The opening casement plate 10 is constructed

그 외부로는 상부의 배기구와 연결되어 배기되는 하부 배기구 배관(13)이 구성된다 Outside thereof, the lower exhaust pipe 13 is connected to the upper exhaust port and exhausted.

그다음 (도 1참조)상기 4행정엔진의 반대측면에는 상기 엔진 실린더(70)하부의 일면에 하부 흡입구가(22)이 구성되고 그다음 엔진의 내부압력과 외부압력의 차이로 열리고 닫히는 여닫이판(20)Then (see Fig. 1) on the opposite side of the four-stroke engine is a lower inlet port 22 is formed on one surface of the lower part of the engine cylinder 70, and then the opening and closing plate 20 is opened and closed by the difference between the internal pressure and the external pressure of the engine )

이 구성되고 그 외부로는 내외부의 공기 유출을 통제할수 있는 밸브(21)가 구성된 배관(23)이 구성된다 .The pipe 23 is configured and the outside is configured with a valve 21 for controlling the air outflow inside and outside.

상기와 같은 구성으로 이루어진 본발명은 다음과 같은 실시예로 설명할 수가 있다The present invention having the above configuration can be described in the following embodiments.

실시의 예1Example 1

본발명의 실시 예1은 도3도를 참조하여 설명하면 다음과 같다Embodiment 1 of the present invention will be described with reference to FIG.

상기 4행정엔진이 연료와 공기를 흡입하기 위하여 피스톤이 하강하면 상부의 배기구(90)은 닫히고 상부의 흡입구(91)가 열리면서 연료와 공기가 흡입된다 When the four stroke engine lowers the piston to suck in fuel and air, the upper exhaust port 90 is closed and the upper inlet port 91 is opened to inhale fuel and air.

그리고 피스톤이 최종 하사점에 도달 할때쯤이면 실린더(70)내부는 저압상태가 되면서 피스톤이 하부 흡입구(22)를 지나가게된다 그러면 실린더내 저압으로 하부 흡입구(22)의 여닫이판(20)이 열리면서 외부의 공기가 순간 들어오게된다 그리고 피스톤이 최종 하사점에서 다시 상승행정으로 돌아서 상승하면 실린더(7)내부는 고압상태로 변환되면서 하부흡입구의 여닫이판(20)은 자연스럽게 닫히게되면서 피스톤은 상승하여 압축폭발 행정에 다다르게 된다 By the time the piston reaches the bottom dead center, the cylinder 70 is in a low pressure state and the piston passes through the lower inlet port 22. Then, the opening plate 20 of the lower inlet port 22 opens at a low pressure in the cylinder. When the outside air comes in at a moment, and when the piston returns to the ascending stroke from the bottom dead center, the cylinder 7 is converted into a high pressure state, and the opening plate 20 of the lower inlet is naturally closed while the piston is raised and compressed. An explosive stroke is reached

이때 반대쪽에 구성된 하부 배기구(12)의 여닫이판(10)은 스프링(11)에 의하여 닫힌상태를 지속하게된다 다만 배기구의 여닫이판(10)의 스프링(11)은 배기에 지장이 없을정도로 약하게 설정해놓는것이 바람직하다 물론 스프링이 너무약하면 피스톤이 상승할 때 약간의 압력으로 배기구의 여닫이판(10) 열릴수도 있지만 피스톤이 배기구까지 상승하면서 실린더내에 늘어나는 압력은는 전체 엔진의 면적에서 미미하기에 그로인한 부작용은 무시할수있을정도로 미세하다 At this time, the opening plate 10 of the lower exhaust port 12 configured on the opposite side is kept closed by the spring 11, but the spring 11 of the opening plate 10 of the exhaust port is set weakly so that the exhaust does not interfere. Of course, if the spring is too weak, the opening plate 10 of the exhaust port may open with a slight pressure when the piston rises, but the pressure in the cylinder as the piston rises to the exhaust port is insignificant in the area of the entire engine. Is negligibly fine

실시의 예 2Example 2 of implementation

본발명의 실시의 예2는 도 4를 참조하여 설명하면 다음과 같다Embodiment 2 of the present invention will be described with reference to FIG. 4 as follows.

상기 4행정 엔진이 흡입행정과 압축행정을 거쳐 폭발행정에 다다라 폭발을 한후 피스톤이 폭발압력에 의하여 하강을 하게되면 상기 하부 흡입구 여닫이판(20)과 하부의 배기구 여닫이판((11)은 피스톤이 하부 흡입구와 배기구에 도달하기전까지는 닫힌상태가 유지된다 하지만 하지만 피스톤이 고압을 동반하여 하부의 흡입구(22)와 배기구(12)에 도달하면 상부의 배기구(90)와 동시에 하부의 배기구(12) 여닫이판(11)은 열리면서 배기를 시작하게된다 After the four-stroke engine reaches the explosion stroke through the intake stroke and the compression stroke, and the piston is lowered by the explosion pressure, the lower inlet opening and closing plate 20 and the lower exhaust opening and closing plate ((11)) have a lower piston. It remains closed until it reaches the inlet and exhaust ports. However, when the piston reaches the inlet port 22 and the exhaust port 12 at the lower side with high pressure, the lower exhaust port 12 at the same time as the upper exhaust port 90 is opened. The plate 11 is opened to start exhausting

이때 하부의 흡입구(22)의 여닫이판(20)는 배출가스 압력으로 굳게닫히게되고 상부의 흡입구 역시 굳게 닫힌상태가 유지된다 At this time, the opening plate 20 of the lower inlet 22 is firmly closed by the exhaust gas pressure, and the upper inlet is also firmly closed.

그다음 피스톤이 하행정 최종 하사점에서 상행정 상사점으로 변환되어 상승하게되는 시간동안 하부의 배기구(12)는 배기를 지속하게된다 그리고 피스톤이 상승하면서 하부 배기구(12)를 지나면서 자연스럽게 하부 배기구는 피스톤에 막히면서 하부의 배기구(12) 배기는 끝나게된다 그런다음 상부의 배기구(90)는 여분의 배출가스를 종래의 4행정엔진이 배기하는것과 동일하게 배기를 하게된다 Then the lower exhaust vent 12 continues to exhaust during the time that the piston is converted from the lower stroke bottom dead center to the upper stroke top dead center, and the lower exhaust vent 12 continues to exhaust. Closing the piston, exhaust of the lower exhaust port 12 is finished. The upper exhaust port 90 then exhausts the exhaust gas in the same way as a conventional four-stroke engine.
