Description

로우터리 엔진{rotary engine}Rotary engine

본 발명은 회전피스톤에 해당하는 편심로우터가 하우징 내에서 직접 회전하는 로우터리 엔진에 관한 것이다.The present invention relates to a rotary engine in which an eccentric rotor corresponding to a rotating piston rotates directly in a housing.

종래의 반켈엔진(Wankel engine)은 타원형의 하우징(housing)내에서 삼각형로우터(rotor)가 회전할때 그 삼각형 정점의 마모율이 높기 때믄에 내구성이 저하되고 제작상의 정밀도가 높아서 생산원가가 높아지는 결점이었고, 종래의 피스톤 엔진은 피스톤의 왕복운동을 회전운동으로 전환하는데 따른 관성저항으로 진동이 심하고 출력이 저감되는 결점이 있었다.The conventional Wankel engine has a drawback of low durability and high production precision due to high wear rate of the triangular vertices when the rotor rotates in an elliptical housing. In the conventional piston engine, the vibration is severe and the output is reduced due to the inertia resistance caused by converting the reciprocating motion of the piston into the rotational motion.

본 발명은 구조사 간단하여 제작이 용이하고 생산원가가 저렴하고 출력이 향상되고 연비가 높고 진동이 없는 엔진을 제공하는데 목적이 있다.The present invention aims to provide an engine which is simple in structure, easy to manufacture, low in production cost, high in output, high in fuel economy and free from vibration.

본 발명은 하우징 내 중심에 편심의 로우터(rotor) 축을 설치하고 로우터의 외주면에는 오목한 오면(凹面)을 형성하고 하우징의 정상에 형성한 블록(block)의 중공부에는 로우터의 상면에 재치한 두 칸막이판을 삽입하고 좌측칸막이판의 중심선상에 천설(穿設)한 홈에는 미끄럼판을 끼워서 상하운동케하고 칸막이판 우측의 하우징 내벽에는 연소실을 형성하여 연료분사변과 점화플러그(plug)를 설치하고 하우징 하저의 좌우측면에는 흡기공과 배기공을 천설하는 것이다.The present invention provides an eccentric rotor shaft in the center of the housing, and forms a concave concave surface on the outer circumferential surface of the rotor, and two partitions mounted on the upper surface of the rotor on the hollow portion of the block formed on the top of the housing. Insert the plate and insert the sliding plate into the groove placed on the center line of the left partition plate and move it up and down.In the inner wall of the housing on the right side of the partition plate, a combustion chamber is formed to install the fuel injection valve and the spark plug. Intake and exhaust holes are laid in the left and right sides of the housing bottom.

본 발명은 하우징내의 편심로우터에 의하여 고도로 압축된 고압의 흡입공기를 로우터의 공기실로 완전히 유입케하여 칸막이 우측의 연소실에 공급하여 연료분사변에서 분사한 연료를 완전 연소케하기 때문에 출력이 크게 향상되고 구조가 간단하고 내구성이 높고 생산원가가 저렴한 효과가 있다.The present invention allows the high pressure suction air, which is highly compressed by the eccentric rotor in the housing, to be completely introduced into the air chamber of the rotor to supply the combustion chamber on the right side of the partition to completely burn the fuel injected from the fuel injection valve, thereby greatly improving the output power. Simple structure, high durability and low production cost.

원형의 하우징(1)내 중심에 편심의 로우터(rotor)(2) 축(3)을 설치하고 로우터(2)의 외주면에 오목한 요면(凹面)(4)을 형성하고 하우징(1)의 정상(頂上)에 형성한 블록(brock)(5)의 중공부에는 로우터(2)의 상면에 재치(載置)한 두 칸막이판(6)(6')을 삽입하고 좌측칸막이판(6)의 중심선상에 길게 천설(穿設)한 홈(7)에는 미끄럼판(8)을 끼워서 상하운동케하고 칸막이판(6)(6') 상방에는 윤활유실(9)을 형성하고 칸막이판(6') 우측의 하우징(1) 내벽에는 연소실(10)을 형성하여 연료부사변(11)라 점화플러그(12)를 설치하고 하우징(1) 하저의 좌우 양측면에는 흡기공(13)과 배기공(14)을 천설하여서 된 것이다.An eccentric rotor 2 shaft 3 is provided in the center of the circular housing 1, and a concave concave surface 4 is formed on the outer circumferential surface of the rotor 2, and the top of the housing 1 Into the hollow portion of the block 5 formed in the upper part, two partition plates 6 and 6 'mounted on the upper surface of the rotor 2 are inserted, and the center of the left partition plate 6 is inserted. A sliding plate 8 is inserted into the groove 7 which is long laid on the ship, and the upper and lower movements are made. A lubricating oil chamber 9 is formed above the partition plates 6 and 6 'and the partition plate 6' is provided. The combustion chamber 10 is formed on the inner wall of the housing 1 on the right side to install the spark plug 12 called the fuel incidence 11, and the intake hole 13 and the exhaust hole 14 are disposed on both left and right sides of the lower part of the housing 1. It was made by laying snow.

도면 중 미 설명 번호 15, 15', 16, 16' 는 기밀 실(seal), 17은 스프링을 표시한 것이다.In the drawings, reference numerals 15, 15 ', 16 and 16' denote airtight seals and 17 denote springs.

이상과 같이 구성 된 본 발명의 작용을 표시하면 다음과 같다.The operation of the present invention configured as described above is as follows.

편심로우터(2)의 외주면이 하우징(1) 내벽에 밀접되어서 회전하면 흡기공(12)을 통하여 흡기된 공기를 압축한다.When the outer circumferential surface of the eccentric rotor 2 is rotated in close proximity to the inner wall of the housing 1, the air taken in through the intake hole 12 is compressed.

도 1과 같이 고도로 압축된 공기의 부피가 극도로 작아져도 칸막이판(6)(6')의 하단은 윤활유실(9) 내의 압력공기 및 스프링(17) 탄력에 의하여 로우터(2)의 상면에 밀착되어서 기밀을 유지하므로 압축공기가 우측의 하우징 공간쪽으로 새나가지 않는다. 그리고 좌측 칸막이판(6)의 홈(7)에 끼운 미끄럼판(8)의 하단은 고압공기 압력에 밀려서 약간 상승하였다가 로우터(2) 외주면에 형성한 오목한 요면(凹面)(4)이 미끄럼판(8) 직하에 도달하였을때 원상위치로 다시 내려온다. 흡기의 압축행정에서 고도로 압축된 고압공기 전부가 요면(4)내에 유입하였기 때문이다.Even if the volume of highly compressed air is extremely small as shown in FIG. 1, the lower ends of the partition plates 6 and 6 ′ are formed on the upper surface of the rotor 2 by the elasticity of the pressure air and the spring 17 in the lubricating oil chamber 9. The tight airtight seal ensures that compressed air does not leak into the housing space on the right. The lower end of the sliding plate 8 inserted into the groove 7 of the left partition plate 6 slightly rises due to the high pressure air pressure, and then the concave concave surface 4 formed on the outer peripheral surface of the rotor 2 is a sliding plate. (8) When it reaches directly below, it comes back down to its original position. This is because all of the highly compressed high-pressure air flows into the concave surface 4 in the compression stroke of the intake air.

이와 같이 압축공기로 충만된 요면(4)이 계속 이동하여 하우징 내벽에 형성된 연소실(10) 밑에 도달하는 순간 요면(4)에 충만된 고압공기가 연소실(10)내로 분출됨과 동시에 연료분사변(11)에서 분사한 연료와 혼합되고 점화플러그(12)에 의하여 착화되면 폭발적으로 연소하는 고압가스가 편심로우터(2)를 밀쳐서 토오크(torque)를 발생케 한다. 이와 같이 연소가스의 팽창행정에 의하여 로우터(2)는 고속으로 회전하고 배기가스는 배기공(13)으로 신속히 배출된다.As soon as the concave surface 4 filled with compressed air continues to reach under the combustion chamber 10 formed on the inner wall of the housing, the high pressure air filled in the concave surface 4 is ejected into the combustion chamber 10 and at the same time, the fuel injection valve 11 When mixed with the fuel injected from the ignition and ignited by the spark plug 12, the high-pressure gas, which is explosively burned, pushes the eccentric rotor 2 to generate torque. In this way, the rotor 2 rotates at a high speed by the expansion stroke of the combustion gas and the exhaust gas is quickly discharged to the exhaust hole 13.

이상과 같이 편심로우터(2)의 고속회전에 의하여 흡입, 압축, 폭발, 배기의 4행정을 원활히 수행하여 편심로우터(2)가 직접 회전하므로 진동이 없고 출력이 크게 향상되어서 연비가 높고 구조가 간단하여 생산원가가 저렴하다.As described above, four strokes of suction, compression, explosion, and exhaust are performed smoothly by the high-speed rotation of the eccentric rotor 2, so that the eccentric rotor 2 is directly rotated, so there is no vibration, and the output is greatly improved, fuel economy is high, and the structure is simple. The production cost is low.

윤활유실(9)는 칸막이판(6)(6')의 윤활작용으로 내구성을 높이고 또 스프링(17)과 함께 공기탄력도 조성되는 효과가 있다.The lubricating oil chamber 9 has the effect of increasing durability by lubricating the partition plates 6 and 6 'and also forming air elasticity together with the spring 17.
