본 고안은 디젤차량의 매연저감구조에 관한 것으로, 특히 배기파이프를 통해 배출되는 미연소가스를 포집하여 배출매연을 저감시킬 수 있도록 하고자, 소음기를 통과한 직후의 배기파이프에 배기가스의 토출압에 의해 회전가능한 매연포집필터를 장착하고 이 매연포집필터에 외기를 공급하도록 된 것이다.The present invention relates to a smoke reduction structure of a diesel vehicle. In particular, in order to reduce the exhaust smoke by collecting the unburned gas discharged through the exhaust pipe, the exhaust pressure immediately after passing through the silencer is applied to the discharge pressure of the exhaust gas. By installing a rotatable soot collecting filter and supplying outside air to the soot collecting filter.
종래 버스나 기타 상용차등 디젤차량은 촉매 컨버터와 같은 배기가스 정화장치가 없어 소음기를 통과하는 배기가스중에 미연소 매연가스의 대기배출량이 많아 대기오염의 한 요인이 되고 있으며, 또 디젤차량은 가솔린 차량에 비하여 CO, 블로바이가스중의 HC, 연료증발가스의 배출량이 적으나, 흑연의 배출량이 많은 문제점이 있다.Conventional diesel vehicles such as buses and other commercial vehicles do not have an exhaust gas purification device such as a catalytic converter, and thus, the exhaust gas passing through the silencer has a large amount of atmospheric combustion of unburned soot gas, which causes air pollution. Compared with the amount of CO and HC in the blow-by gas and the fuel evaporation gas, the emission of graphite is high.
특히 디젤차량의 흑연배출은 연소중에 국부적으로 산소가 부족하여 불완전연소가 일어났을 때 발생하며 이는 곧 그을음으로 배출되어 대기를 오염시키고 스모그의 원인이 되거나 시계를 저하시키는 원인이 되고 있다.Particularly, diesel emissions of diesel vehicles occur when incomplete combustion occurs due to local oxygen deficiency during combustion, which is emitted as soot, which pollutes the atmosphere, causes smog, and decreases visibility.
디젤엔진은 가솔린 엔진과 달리 운전상태가 변화하여도 연소실중에 흡입되는 공기량이 거의 일정하여 고부하 또는 가속할 때와 연료분사량이 많은 경우에 불완전연소를 일으켜 흑연을 발생시키게 되며, 흑연발생에 영향을 주는 요소는 분사펌프, 분사시기의 상태불량(분사시기지연), 노즐등의 이외에도 경유의 휘발성, 조성등이 관계된다.Unlike gasoline engines, diesel engines generate graphite due to incomplete combustion at high loads or accelerations and when there is a large amount of fuel injection because the amount of air sucked into the combustion chamber is almost constant even if the operating conditions are changed. The urea is related to the volatility, composition, etc. of the diesel fuel, in addition to the injection pump, the failure of the injection timing (injection delay), the nozzle, and the like.
또한 분사펌프나 노즐은 연료분사시 연료입자를 충분히 작게 하여 공기와 잘 혼합시키는 것이 좋고, 휘발성이 높을수록 공기와의 혼합이 촉진되어 산소부족에 의한 그을음발생이 감소하게 된다.In addition, the injection pump or the nozzle is good to make the fuel particles sufficiently mixed with the air during the fuel injection, and the higher the volatility, the better the mixing with the air, so that the generation of soot caused by lack of oxygen is reduced.
본 고안의 목적은 디젤엔진에서 흑연등과 같은 매연가스의 배출량을 크게 저감하기 위한 것이다.The purpose of the present invention is to greatly reduce the emissions of soot gas such as graphite in diesel engines.
이를 위하여 소음기를 통과한 직후의 배기파이프에 조밀한 메쉬를 갖는 금속망으로 된 매연포집필터를 장착하여 배기가스의 토출압에 의해 회전가능케 하고 매연포집필터에는 외기를 공급하도록 된 것이다.To this end, the exhaust pipe immediately after passing through the silencer is equipped with a soot collecting filter made of a metal mesh having a dense mesh to be rotatable by the discharge pressure of the exhaust gas, and to supply the outside air to the soot collecting filter.
이하, 본 고안의 실시예를 첨부도면에 의하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
제1,2도와 같이 배기파이프(10)와, 배기파이프(10)에 형성된 소음기(11)와, 소음기(11) 통과직후의 배기파이프(10)에 형성된 매연포집케이스(12)와, 조밀한 메쉬를 갖는 금속망으로 되어 매연포집케이스(12)에 회전가능하게 장착된 매연포집필터(13)와, 매연포집필터(13)를 분리하여 세정할 수 있도록 매연포집케이스(12)에 부착된 커버(14)와, 매연포집케이스(12)하부일측에 형성되어 매연포집필터(13)에 외기를 공급하는 급기공(15)으로 구성된 것이다.As shown in FIGS. 1 and 2, the exhaust pipe 10, the silencer 11 formed in the exhaust pipe 10, the soot collecting case 12 formed in the exhaust pipe 10 immediately after passing through the silencer 11, and A cover attached to the soot collecting case 12 so as to separate and clean the soot collecting filter 13 and the soot collecting filter 13 that are made of a metal mesh having a mesh and rotatably mounted to the soot collecting case 12. 14 and an air supply hole 15 formed on one side of the soot collecting case 12 to supply outside air to the soot collecting filter 13.
따라서 본 고안은 제1, 2도에서 보는 바와같이 연소를 마친 배기가스가 배기파이프(10)의 소음기(11)를 통해 음파의 간섭, 압력변동의 감소, 배기온도의 저하등을 일으켜 점차 소음되면서 매연포집케이스(12)에 유입되면 이 배기가스의 토출압력에 의해 매연포집필터(13)가 회전하고 매연포집케이스(12)의 급기공(15)으로부터 유입되는 외기가 매연포집필터(13)에 그 회전방향과 반대방향으로 작용하여 저항을 발생시킴으로써 이때 매연포집필터(13)에 배기가스중의 흑연분진이 포집되면서 매연을 저감시키게 되는 것이다.Therefore, the present invention, as shown in the first and second degrees, the exhaust gas after the combustion is silenced gradually through the silencer 11 of the exhaust pipe 10 causing interference of sound waves, reduction of pressure fluctuations, reduction of exhaust temperature, etc. When the soot collecting case 12 flows in, the soot collecting filter 13 rotates due to the discharge pressure of the exhaust gas, and outside air introduced from the air supply hole 15 of the soot collecting case 12 enters the soot collecting filter 13. By acting in the direction opposite to the rotation direction to generate a resistance at this time it is to collect the graphite dust in the exhaust gas in the particulate filter 13 to reduce the soot.
한편 매연포집필터(13)는 커버(14)를 분리하고 매연포집케이스(12)로부터 꺼내어 주기적으로 청소하여 줌으로써 연속반복적으로 사용할 수 있다.On the other hand, the soot collecting filter 13 can be used repeatedly and repeatedly by removing the cover 14, taken out from the soot collecting case 12 and periodically cleaned.
이상과 같이 본 고안은 배기파이프의 소음기 통과측에 매연포집케이스를 형성하고 매연포집케이스내에 금속망으로 된 매연포집필터를 회전가능하게 장착하면서 케이스 하부에 급기공을 형성함으로써 배가가스중의 흑연분진등 매연가스의 대기 배출량을 크게 저감시켜 공해방지에 기여하게 된 것이다.As described above, the present invention forms a smoke collecting case on the side of the silencer passing through the exhaust pipe, and forms a supply air hole in the lower part of the case while rotatably mounting a smoke collecting filter made of a metal mesh inside the smoke collecting case, thereby forming graphite dust in the exhaust gas. This greatly contributed to the prevention of pollution by greatly reducing the emissions of soot gas.
