本論文主要分析噪音濾清器對柴油引擎黑煙排放改善之研究。實驗是以三部使用率甚高之不同車廠、不同性能、不同車型、不同用途的重型柴油車作為測量,分別裝載三具大小不一、不同製造商、不同功能,在結合傳統消音器下,研究尾放處理系統的濾煙、噪音淨化效果。 研究方式是將裝載三具濾煙器之車輛在未裝載前及裝載後,以實際行駛於道路一段里程及一段時間後追蹤、記錄、取樣、測量該三車的使用情形,經探討分析顯示微細顆粒狀污染物明顯下降,濃度減少率約在76.6-89.7%;一氧化碳(CO)及碳氫化合物(HC)轉化成二氧化碳(CO2)及水,一氧化碳轉換率約為50-90%及碳氫化合物轉換效率約50-70%之間的效果;在多環芳香烴化合物(PAHs)的排放係數亦減少約38.6-50.2%有效降低高環數多環芳香烴化合物(PAHs)值,濃度有明顯下降趨勢;尤其在行駛一段遠距離後,因載體吸收排氣高溫後,產生復燃再生現象效果更佳良好,實驗結果顯示尾端處理系統是有降低污染源的功能。
This thesis analyzes the noise filter on the improvement of black smoke emissions from diesel engines.The experiment is based on three different high utilization rate of depot, different performance, different models for different uses heavy-duty diesel vehicles, as measured, respectively, to load three different sizes, different manufacturers, different functions, combined with traditional muffler,The study tail pipe treatment systems filter the smoke, noise, purifying effect. Study approach is the vehicle that will carry three filter Before loading and after loading, the real driving on the road for some miles and after a period of tracking, recording, sampling, measurement of the usage of the car, After the study, analysis showed that fine particulate pollutants decreased, Concentration to reduce the rate of about 76.6-89.7%; carbon monoxide (CO) and hydrocarbons (HC) into carbon dioxide (CO2) and water, carbon monoxide conversion rate of about 50-90% and hydrocarbon conversion efficiency of about 50-70% between the results; reduced by about 38.6-50.2% of the emission factors of polycyclic aromatic hydrocarbons (PAHs) to reduce the value of the high ring number polycyclic aromatic hydrocarbons (PAHs)value,concentration, a clear downward trend, Especially in the running for some distance,Due to carrier absorption of the exhaust high temperature,Produce the resurgence of regeneration phenomenon better, experimental results show that the tail pipe handling system is to reduce pollution sources.
