Description

柴油引擎車輛因其是以壓縮點火方式引燃柴油或替代性燃料後經於氣缸內之燃燒反應將燃料之化學能依序轉換為熱能及動力輸出，因此在燃燒過程也產生各種氣、液、固態污染物，最主要為粒狀物(PM)、黑煙(smoke)、氮氧化物(NOx)等。另外也排放一氧化碳(CO)、硫氧化物(SOx)、二氧化碳(CO2)、及碳氫化合物(HC)等氣狀污染物，造成破壞臭氧層、引致酸雨、提升溫室效應等全球性生態環境破壞問題，也造成人體健康的危害，因此為大眾所關切。比如氮氧化物經形成硝酸則產生酸雨，亦會破壞臭氧層、與陽光作用產生光化煙霧；粒狀污染物或黑煙中若含多環芳香烴(PAHs，polycyclic aromatic hydrocarbons)或金屬化合物則可能造成肺部、氣管、呼吸道等病變。根據全國地區空氣污染源排放資料庫TED 4.2版之推估資料顯示占全國3%機動車輛數之柴油車排放來自於所有移動污染源之46% PM與51% NOx，尤其全國客貨運業者幾乎皆使用柴油車為運輸工具，因此如何由防制技術或管制策略著手削減柴油車排氣污染，以改善空 氣品質，實為現今之重要課題。 Diesel engine vehicles convert the chemical energy of the fuel into heat energy and power output in sequence through the combustion reaction in the cylinder after the diesel engine or the alternative fuel is ignited by compression ignition. Therefore, various gases, liquids, and Solid pollutants, mainly granules (PM), smoke, nitrogen oxides (NO x ), etc. It also emits gaseous pollutants such as carbon monoxide (CO), sulfur oxides (SO x ), carbon dioxide (CO 2 ), and hydrocarbons (HC), causing global environmental damage such as ozone depletion, acid rain, and greenhouse effect. Destruction problems also cause harm to human health and are therefore of concern to the public. For example, the formation of nitric acid by nitrogen oxides produces acid rain, which also destroys the ozone layer and acts as a photochemical smog with sunlight. Particles or black smoke may contain polycyclic aromatic hydrocarbons (PAHs) or metal compounds. Causes lung, trachea, respiratory tract and other diseases. According to the national regional air pollution emissions database TED 4.2 version of the conjecture data show that accounting for 3% of the number of motor vehicle diesel emissions from all mobile sources of 46% PM and 51% NO x, in particular, the national passenger and freight operators almost all use Diesel vehicles are transportation vehicles. Therefore, how to prevent diesel engine exhaust pollution from improving the air quality by prevention technology or control strategy is an important issue today.

The fuel control valve controls the start time of the fuel control valve to output the fuel to the fuel atomizing nozzle 61 to eject the oil and gas atomized into fine molecules; at the same time, the compressed air source delivers the high pressure air to the air valve, and the air valve controls the output. The amount of air is mixed to the previously atomized oil and gas, and then the controller controls the ignition device 63 to be electrically heated, igniting the atomized oil and gas, completely combusting the exhaust gas formed in the cone cover 3, and the exhaust gas flow after combustion Each of the long tubular members 31A and the respective short tubular members 31B and the small-diameter ends are discharged through the tapered cover 3, and the outer long tubular member 31A and the short short tubular members 31B are interfered by the respective short tubular members 31B due to the exhaust gas in the tapered cover 3, thereby staying in the tapered cover. The time within 3, thus allowing the exhaust gas to be more fully burned; after the exhaust gas that has passed through the cone cover 3 is again guided by the vanes 321 of the airflow guiding member 32 to concentrate the airflow, Concentrated by the exhaust gas stream through the filter core 41, using a high temperature exhaust gas adhering to the soot filter core 41 to clear the combustion; When the carbon deposit is removed to a certain extent, the filter core 41 is restored to an unobstructed state, and the exhaust gas can be smoothly discharged.
再者，本創作還藉由前述的防焰單元可以避免通過濾蕊41的高溫廢氣將火焰噴出出氣端5；當火焰從濾蕊41噴出時，火焰會受到擋板52阻擋，從而使火焰回溯至濾蕊41以對廢氣及積碳進行二次燃燒，充分燃燒後的廢氣則通過網片51與出氣端5排出。 Furthermore, the present invention also prevents the flame from being ejected from the gas outlet end 5 through the high-temperature exhaust gas of the filter core 41 by the flame-proof unit described above; when the flame is ejected from the filter core 41, the flame is blocked by the baffle 52, thereby causing the flame to trace back. The filter core 41 is subjected to secondary combustion of the exhaust gas and the carbon deposit, and the exhaust gas after the full combustion is discharged through the mesh 51 and the gas outlet end 5.
另一方面，本創作可以在所述燃燒單元2的外殼壁前方設置一貫通的第一內視孔22A，以及在燃燒單元2的外殼壁後方設置一貫通的第二內視孔22B，讓工作人員可以將內視鏡經由該第一內視孔22A或第二內視孔22B伸入燃燒單元2內觀察廢氣被燃燒的情況。 On the other hand, in the present invention, a through first inner view hole 22A may be disposed in front of the outer wall of the combustion unit 2, and a through second inner view hole 22B may be disposed behind the outer casing wall of the combustion unit 2 for work. A person can extend the endoscope through the first inner view hole 22A or the second inner view hole 22B into the combustion unit 2 to observe that the exhaust gas is burned.
以上所述者僅為用以解釋本創作之較佳實施例，並非企圖具以對本創作做任何形式上之限制，是以，凡有在相同之創作精神下所作有關本創作之任何修飾或變更，皆仍應包括在本創作意圖保護之範疇。 The above description is only for the purpose of explaining the preferred embodiment of the present invention, and is not intended to impose any limitation on the present creation, so that any modifications or changes to the creation made in the same creative spirit are made. , should still be included in the scope of protection of this creative intent.
