It is reported that the particulate matter in exhaust gas is reduced when oxygenated agents are added to diesel fuel, but the inhibition mechanisms is not established. To explain this mechanism, we investigates the amounts of particulate formation an

The platinum ion-exchanged ZSM-5 zeolite catalyst (Pt-5), which reduces nitrogen oxides (NOx) in the presence of oxygen and hydrocarbons, was applied to actual diesel engine exhaust. Compared to the Cooper ion-exchanged ZSM-5 zeolite catalyst, the Pt
