Abstract
Diesel Particulate Filter (DPF) is regenerated in particulate matter (PM) oxidation reaction when PM was loaded. In this report, it makes a study regarding basic calculation method of kinetics parameters using the oxidation reaction process of PM that was simulated by laboratory experiments with synthetic gases. Additionally, it reports on the results of examining the relation between temperature and time when a DPF is regenerating, using kinetic parameters.ディーゼルエンジンから排出される粒子状物質はDPFで捕集後に酸化除去される。本件では、粒子状物質の酸化反応過程をモデルガス試験で再現し、酸化に関わる速度論パラメータの導出方法について基礎的な検討を行った。さらに、導出したパラメータからDPF再生時の温度と時間の関係についても検討した結果を報告する。
