Abstract
It is reported that the particulate matter in exhaust gas is reduced when oxygenated agents are added to diesel fuel, but the mechanism of the reduction is not established. To explain this mechanism, we investigated the thermal cracking processes of diesel fuel added oxygenated agents in various surroundings using thermal cracking apparatus. When oxygenated agents are added to diesel fuel, the thermal cracking starts at lower temperatures and the oxygenated agents promote the oxidation of unsaturated cracking constituents, such as ethylene. Thus, through the suppressed benzene and PAH formation, the reduction of the formation of particulate matter can be expected.
