本研究論文利用廢輪胎在高溫裂解爐內做熱裂解處理，產生之生成氣體，以冷凝方式將生成氣體冷凝，產生之輪胎裂解油，依10%、20%比例的輪胎裂解油，與市售柴油混合後，稱為輪胎裂解生質油。本實驗利用TOYOTA MK35SA柴油引擎實車，與動力計做測試，調整三種噴油正時與引擎轉速，探討柴油引擎添加輪胎裂解油在汽缸內之噴霧燃燒過程特性，配合過去建立之油滴霧化模式，建立燃燒關係式，得到燃燒開始角度(θB)，在實車引擎測試下，量測引擎的耗油率，並模擬三種油品在汽缸內燃燒過程之溫度、壓力與指示熱效率，結果顯示添加輪胎裂解油會增加耗油率，且提高汽缸燃燒過程之溫度與壓力，同時提升引擎之熱效率，並量測有害排放氣體組成，例如一氧化碳(CO)、二氧化碳(CO2)、氮氧化物(NOx)、碳氫化合物(HC)，建立輪胎裂解油之噴霧燃燒特性與排放氣體關係，探討柴油引擎添加輪胎裂解油作為生質柴油之可行性。
