본 고안은 디이젤 엔진용 매연 감소장치에 관한 것이다.The present invention relates to a smoke reduction device for diesel engines.
흡기, 압축, 연소, 배기의 4행정으로 이루어지는 디이젤 엔진은 공기 청정기를 통하여 실린더내로 공기를 흡입시켜 압축한 다음, 연료 분사장치인 노즐로 부터 연료를 무화 분사시켜 공기의 압축열에 의해 연료가 자연 연소되면서 피스톤을 작동시킨후, 소음기를 거쳐 외부로 배기되도록 되어 있다.The diesel engine, which consists of four strokes of intake, compression, combustion, and exhaust, sucks air into the cylinder through an air cleaner, compresses it, and atomizes the fuel from the nozzle, a fuel injector, to naturally burn fuel by the heat of compressed air. After operating the piston, the silencer is exhausted to the outside.
그런데, 이와같은 종래의 디이젤 엔진은 실린더내로 공기가 흡입시 공기 청정기를 거쳐 흡입되기 때문에 공기의 원활한 흡입이 이루지 못하게 되고, 또한 배기시에도 직렬로 연결된 1개 이상의 소음기를 거쳐 배기되도록 되어 있기 때문에 배기가스의 원활한 배출이 이루어지지 못하게 됨으로써, 실린더 내에서 연소되는 연료가 불완전 연소되는 결과가 초래되는 실정이었다.However, such conventional diesel engines do not achieve smooth intake of air because air is sucked through the air purifier when the air is sucked into the cylinder, and exhausted through one or more silencers connected in series during exhaust. Since the gas is not discharged smoothly, the fuel combusted in the cylinder results in incomplete combustion.
또한, 실린더내로 공기가 흡입되는 과정에 있어서도 가속페달을 밟았을때, 노즐에서 분사되는 연료에 비하여 공기흡입 밸브를 통하여 흡입되는 공기가 항상 일정하게 제한 됨으로써, 연료와 공기의 조성비가 맞지 않게 되어 불완전연소가 일어나고 따라서 매연이 발생하게 되는 폐단이 있었다.In addition, even when the accelerator pedal is pressed in the process of inhaling the air into the cylinder, the air sucked through the air intake valve is always constantly limited compared to the fuel injected from the nozzle, so that the composition ratio of the fuel and the air becomes incomplete. There was a closed end where combustion took place and thus smoke.
본 고안은 이와같은 종래의 제반 문제점을 해소하기 위하여 고안된 것으로써, 종래의 하나씩 직렬로 연결되던 공기청정기와 소음기를 병렬로 2개이상 설치함으로써, 공기의 흡입 및 배출을 보다 원활하게 하고, 실린더의 공기 흡입 밸브 부근에 실린더내의 공기압에 의해 자동으로 작동되는 보조 흡입밸브를 착설함으로써, 가속시 실린더내로 보다 많은 공기가 흡입될 수 있도록 하여 연료의 완전 연소에 의한 매연이 감소될 수 있도록 한 디이젤 엔진용 매연 감소장치를 제공하고자 함에 그 목적이 있다.The present invention was devised to solve such problems in the related art, and by installing two or more air purifiers and silencers connected in series one by one in the prior art, the intake and discharge of air more smoothly, For diesel engines near the air intake valve, an auxiliary intake valve operated automatically by the air pressure in the cylinder allows more air to be drawn into the cylinder during acceleration, thereby reducing the smoke from complete combustion of the fuel. The purpose is to provide a smoke reduction device.
이하, 본 고안을 첨부도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안의 전체구조를 나타낸 것으로서, 2개이상의 흡입관(2a)(2b)을 통해 연결된 2개이상의 공기청정기(1)(1a)로 부터의 흡입공기는 흡입관(2)을 거치고 실린더(3)의 공기흡입밸브(4)와 보조흡입밸브(5)를 경유하여 흡입되도록 하고, 상기 실린더(3)의 배기관(6)을 통해 배출되는 배기가스는 2개이상의 소음기(7)(7a)를 경유하여 배출되도록 한 것이다.Figure 1 shows the overall structure of the present invention, the suction air from the two or more air cleaners (1) (1a) connected through two or more suction pipes (2a) (2b) through the suction pipe (2) and the cylinder ( The exhaust gas is sucked through the air suction valve 4 and the auxiliary suction valve 5 of 3), and the exhaust gas discharged through the exhaust pipe 6 of the cylinder 3 is two or more silencers 7 and 7a. It is to be discharged via.
제2도 및 제3도는 본 고안의 실린더의 구성을 나타낸 것으로서, 흡입관(2)과 연결된 공기흡입밸브(4)에 근접된 위치에 스프링(8)의 탄성을 받는 보조흡입밸브(5)를 설치하여 실린더(3) 내부에 인력이 발생하였을때 스프링(8)이 압축되면서 보조흡입 밸브(5)가 열러 흡입관(2)을 통한 공기가 실린더(3) 내부로 많이 흡입되도록 한 것이다.2 and 3 show the configuration of the cylinder of the present invention, and the auxiliary suction valve 5 receiving the elasticity of the spring 8 is installed at a position close to the air suction valve 4 connected to the suction pipe 2. When the attraction force occurs inside the cylinder 3, the spring 8 is compressed and the auxiliary suction valve 5 is opened so that the air through the suction pipe 2 is sucked into the cylinder 3 a lot.
도면중 미설명 부호(9)는 배기밸브, (10)은 연료 분사조즐, (11)은 피스톤이다.In the drawings, reference numeral 9 denotes an exhaust valve, 10 a fuel injection nozzle, and 11 a piston.
이와같이 구성된 본 고안의 디이젤 엔진용 매연 감소장치는 실린더(3)와 연결된 공기청정기(1)(1a)와 소음기(7)(7a)가 병렬로 2개이상 설치됨으로써, 공기의 흡입 및 배기가스의 배출시 보다 원활하게 공기와 배기가스가 흡입, 배출될 수 있게 되어 매연을 현저히 감소시킬 수 있는 이점이 있다.In this configuration, the exhaust gas reducing device for diesel engines of the present invention has two or more air purifiers (1) (1a) and silencers (7) (7a) connected to the cylinder (3) in parallel. When discharged, the air and the exhaust gas can be sucked and discharged more smoothly, thereby reducing the smoke.
또한, 실린더(3)의 공기흡입밸브(4) 부근에 스프링(8)으로 탄착된 보조흡입 밸브(5)를 설치함으로써, 제2도에 도시한 것과 같이 가속시의 흡입행정시에는 실린더(3) 내부에 발생되는 인력에 의하여 스프링(8)이 압축되면서 보조흡입밸브(5)를 열리게 하여 공기가 실린더(3)내로 원활히 유입되도록 유도하고 있기 때문에 실린더(3)내의 공기가 연료의 혼합비가 적정하게 유지됨으로써 완전연소가 이루어져 출력이 향상되고 매연이 감소되는 효과가 있다.Further, by installing the auxiliary suction valve 5 that is secured by the spring 8 near the air suction valve 4 of the cylinder 3, the cylinder 3 at the time of the acceleration stroke as shown in FIG. Since the spring (8) is compressed by the attraction force generated inside to open the auxiliary suction valve (5) to induce air to flow smoothly into the cylinder (3), the mixing ratio of the air in the cylinder (3) is appropriate By maintaining it, it is completely burned and the output is improved and the smoke is reduced.
그리고 배기행정시에는 제3도에 도시한 것과 같이 두 흡입밸브(4)(5)가 닫힌 상태에서 배기관(6)과 연결된 배기밸브(9)만 개방되어 두 소음기(7)(7a)를 통해 배기가스가 원활히 배출되게 되는 특장점이 있다.At the time of the exhaust stroke, only the exhaust valve 9 connected to the exhaust pipe 6 is opened while the two intake valves 4 and 5 are closed as shown in FIG. 3 through the two silencers 7 and 7a. The advantage is that the exhaust gas is smoothly discharged.
이상에서 상술한 바와같이 본 고안의 매연 감소장치에 의하면, 매연이 다량 발생하던 디이젤 엔진을 보다 효과적으로 운용할 수 있는 등의 신규한 고안인 것이다.As described above, according to the soot reduction apparatus of the present invention, it is a novel design such that a diesel engine in which a large amount of soot is generated can be operated more effectively.
