Abstract
Particulate matter (PM) removal in exhaust gas emitted from a stationary diesel engine generator (displacement volume is 200 mL) is performed using ozone injection diesel particulate filter (DPF) regeneration. It is demonstrated that the DPF regeneration by injecting O_3 is achieved successfully at 250℃. The amount of O_3 consumed per PM of 1.0 g is 17.66 g(O_3)/g(PM) and the energy efficiency of PM combustion is 5.24 g(PM)/kWh. The repetitive regeneration of DPF by O_3 injection for practical application is also achieved successfully. The regeneration time is only 12% of the total operation time. It is estimated that a heavy-weight vehicle with the ozone injection DPF regeneration system can meet the new regulation by using electric power of 0.19% of the engine output This system will be applied for the exhaust gas treatment of marine diesel engine and automobile diesel engine.
