Study of Oxygen containing Hydrocarbons in Exhaust Emission from Gasoline SI Combustion

ガソリンSI 燃焼から排出される含酸素炭化水素の検討

In this study, a comprehensive two-dimensional gas chromatography was employed to analyze combustion products in exhaust gas emitted by SI combustion. From the exhaust gas analysis of SI combustion which used regular gasoline and 10W-30 lubricating oil, a lot of peaks which include many compounds produced by lubricating oil were detected. Therefore, n-heptane as fuel and poly-α-olefin as lubricating oil were applied for engine experiments. From the analysis focusing on linear and branched oxygen containing hydrocarbons with seven carbon atoms, it is suggested that many types of oxygen containing hydrocarbons which is not considered in detailed reaction model exist in exhaust gas.GC×GC-TOFMS を用いて,SI 燃焼の排気ガス中に含まれる各種化合物を検討し,特に含酸素化合物については詳細な化学反応モデルで考慮されている成分との比較を行った.その結果,燃料の分子構造とは異なる構造の成分や詳細な化学反応モデルでは考慮されていない多くの含酸素化合物の存在が示唆された.
