To reduce particulate matter (PM) from diesel engines, restrainting amount of generation by improvement of fuel properties, and traping with diesel particulate filter (DPF) are required. However when DPF is regenerated, it is necessary to raise exhaust temperature up to the PM combustion temperature with fuel injected. Therefore it is important to lower the PM combustion temperature considering the fuel cost. This research investigates the effects of fuel properties on the PM combustion temperature, and the effects of reduction treatment to the catalyst which has positive effects in lowering the PM combustion temperature. The result shows that crystal structure effects on the PM combustion temperature, and reduction treatment to catalyst can lower the PM combustion start temperature.
