“…Non-thermal regeneration technologies such as reverse flow systems [9] struggle to effectively regenerate the entire filter volume and use bulky high pressure devices to separate the PM from the filter surface. Difficulties with PM disposal remain after regeneration.…”

“…Non-oxidative methods (e.g. reverse flow [9] ) Thermal regeneration processes increase the PM temperature to typically >550 o C at which, with careful control of gas flow produces a self-sustained oxidation reaction that can regenerate the filter in ~3 minutes. This has been achieved in the past using microwaves [10] (for direct coupling of thermal energy to the PM), electrical heating [11] and diesel fuel burners [6] in the exhaust system.…”

“…Tables A1 and A2 in the Appendix A presents a summary of several noteworthy studies on PM treatment for simulated and actual DEG. DPF has been used widely and the most effective method for reducing PMs in automobile applications [72][73][74][75]. However, owing to the DPM accumulation on the filter walls of the DPF, the blockage DPF frequently occurs.…”

The purification of diesel exhaust gas is of great importance to prevent the atmospheric emission of major pollutants such as diesel particulate matter and nitrogen oxides and meet the environmental regulations. The atmospheric-pressure plasma is attracting increasing interest and is a promising after-treatment technology for purifying diesel emission at low temperatures. However, when compared with the numerous publications on nitrogen oxides reduction by non-thermal plasma, using non-thermal plasma to particulate matter treatment have relatively limited. This work provides a comprehensive review of the plasma applications for diesel particulate matter treatment, including self-regenerating diesel particulate filter, diesel particulate matter removal, and simultaneous removal of diesel particulate matter and nitrogen oxides. The treatment of particulate matter from both simulated particulate matter sources and actual diesel engines also discussed in this comprehensive review. The challenge to this technology is limited energy consumption for plasma, which should be less than 5% (~30 J/L) of the overall fuel consumption. Until now, the atmospheric-pressure plasma has been no commercial implementation in diesel exhaust gas treatment, so more research is needed to be done in this field.

“…Although the use of ceramic diesel particulate filters (DPF) is a leading technology [6], [7] in automobile diesel engines, there remains the problem of removing the accumulated PM from a DPF. Although DPF regeneration at a high temperature can be achieved, technical difficulties still remain in maintaining a high temperature for PM incineration.…”

As the regulations governing diesel engine emissions become more stringent, it is difficult to fulfill these new requirements using only techniques that improve combustion. More effective aftertreatment technology is thus needed particularly for particulate matter (PM). Although the use of ceramic diesel particulate filters (DPF) is a leading technology in automobiles, it still presents a problem in terms of soot removal or regeneration for marine diesel engine operated with marine diesel oil (A-heavy fuel oil) including the sulfur. In the present study, to establish a nonthermal plasma DPF regeneration method for marine diesel engines, laboratory-scale and pilot-scale experiments are carried out. The pressure difference decreased only when the plasma is turned on and that regeneration is realized at 320°C. The amount of ozone required for regeneration is determined under various engine-operating conditions, and basic characteristics of regeneration are clarified. The required plasma energy is approximately 5 % of the generated power of the marine engine.
