Description
本創作係關於一種引擎之排氣裝置,尤指一種適用於機車引擎之排氣裝置。This creation is about an engine exhaust device, especially an exhaust device suitable for locomotive engines.
目前四行程引擎之排氣裝置內所配置之觸媒轉換器,係於金屬筒體上披覆觸媒,觸媒轉換器含有白金(Pt)、及鈀(Pd)等貴金屬,藉由該等貴金屬可將引擎所燃燒不完全而產生之空氣污染物質,如廢氣中的一氧化碳(CO)、及碳氫化合物(HC)等氧化成無害的二氧化碳(CO2)、及水(H2O),而廢氣中的氮氧化合物(NOX),則是經由觸媒所含之貴金屬銠(Rh)還原成無害的氮(N2)、及氧(O2),以達到淨化引擎廢氣中之空氣污染物質。At present, the catalytic converter installed in the exhaust device of the four-stroke engine is coated with a catalyst on a metal cylinder. The catalytic converter contains platinum (Pt) and palladium (Pd) and other precious metals. Precious metals can oxidize the air pollutants produced by incomplete combustion of the engine, such as carbon monoxide (CO) and hydrocarbons (HC) in exhaust gas, into harmless carbon dioxide (CO2) and water (H2O). The nitrogen oxide compound (NOX) is reduced to harmless nitrogen (N2) and oxygen (O2) through the noble metal rhodium (Rh) contained in the catalyst to purify the air pollutants in the engine exhaust.
此外,含氧感知器(Oxygen Sensor 或簡稱 O2 Sensor)的主要目的是在控制引擎中汽油與氧氣的「空燃比」,含氧感知器會自動將在排氣管中所偵測廢氣中氧氣的含量訊息傳回機車之電子控制單元(ECU: Electronic Control Unit),氧氣含量多表示空燃比太稀,氧氣含量少則表示空燃比過濃,如果空燃比太稀,電子控制單元就會驅動噴油嘴多噴一些油把油氣增濃,如果空燃比過濃,電子控制單元就會節制噴油嘴,讓它少噴油一點,如此在電子控制單元快速的運作管控下,很快地就可調整出一個最恰當的空燃比,讓每一滴油都發揮最佳效率,達到省油效果。因此,含氧感知器可用來判斷排氣管中之廢氣是處於過濃或過稀之狀態。In addition, the main purpose of the oxygen sensor (Oxygen Sensor or O2 Sensor) is to control the "air-fuel ratio" of gasoline and oxygen in the engine. The oxygen sensor will automatically detect the oxygen in the exhaust pipe. The content information is sent back to the electronic control unit (ECU: Electronic Control Unit) of the locomotive. More oxygen content means that the air-fuel ratio is too lean, and less oxygen content means that the air-fuel ratio is too rich. If the air-fuel ratio is too lean, the electronic control unit will drive fuel injection Inject more oil into the nozzle to enrich the oil and gas. If the air-fuel ratio is too rich, the electronic control unit will control the injector to make it inject less fuel, so that it can be adjusted quickly under the rapid operation and control of the electronic control unit Find the most appropriate air-fuel ratio, so that every drop of oil can play the best efficiency and achieve fuel saving effect. Therefore, the oxygen sensor can be used to determine whether the exhaust gas in the exhaust pipe is too rich or too lean.
目前市面上機車之噴射供油引擎內部必有一上游含氧感知器,安裝於觸媒轉換器上游,用以偵測排氣含氧量回饋給電子控制單元,ECU藉由控制噴油嘴噴油量來控制引擎空燃比,以維持各操作狀態下最適合的混合比。但隨著污染法規越來越嚴苛,傳統上游含氧感知器無法監測觸媒轉換器之劣化程度,故必須於觸媒轉換器後方增設一下游含氧感知器以偵測觸媒轉換器之劣化程度。At present, there must be an upstream oxygen sensor inside the fuel injection engine of the locomotive on the market, which is installed upstream of the catalytic converter to detect the exhaust gas oxygen content and feed it back to the electronic control unit. The ECU controls the fuel injection nozzle to inject fuel. To control the engine air-fuel ratio to maintain the most suitable mixing ratio in each operating state. However, as pollution regulations become more and more stringent, the traditional upstream oxygen sensor cannot monitor the degradation degree of the catalytic converter. Therefore, a downstream oxygen sensor must be added behind the catalytic converter to detect the deterioration of the catalytic converter. Degree of degradation.
習知技術如台灣M587688專利案揭示其觸媒轉換器前蓋包覆排氣管本體,使得排氣管本體容積變小,且整體設計佈局較困難。另,台灣I672434專利案揭示其含氧感知器支持管之通氣截面積大於觸媒轉換器之通氣截面積,將造成含氧感知器感測廢氣的敏感度降低,難以讀取正確混合比,易造成ECU誤判。又,台灣M587213專利案揭示其消音器前蓋與觸媒轉換器外筒體連結,則含氧感知器合理安裝位置為消音器前蓋之前,將造成消音器容積變小。綜合上述習知技術皆有難以讀取正確混合比、或者消音器容積較小的缺點,皆非十分理想,尚有改善的空間。Conventional technologies such as the Taiwan M587688 patent reveal that the front cover of the catalytic converter covers the exhaust pipe body, which reduces the volume of the exhaust pipe body and makes the overall design and layout difficult. In addition, the Taiwan patent I672434 discloses that the ventilation cross-sectional area of the oxygen sensor support tube is larger than the ventilation cross-sectional area of the catalytic converter, which will reduce the sensitivity of the oxygen sensor to sense exhaust gas, and it is difficult to read the correct mixing ratio. Cause ECU misjudgment. In addition, the Taiwan M587213 patent discloses that the front cover of the muffler is connected to the outer cylinder of the catalytic converter, and the reasonable installation position of the oxygen sensor is before the front cover of the muffler, which will cause the volume of the muffler to decrease. In summary, the above-mentioned conventional technologies have the disadvantages that it is difficult to read the correct mixing ratio or the volume of the muffler is small, which is not very ideal, and there is still room for improvement.
