Outline of Final Research Achievements

New prospective and fundamental chemical processes in atmospheric-pressure nonequilibrium nonthermal plasma combined exhaust gas cleaning technology for clean marine diesel engines are investigated and clarified to cope with near future more stringent emission control regulations. Catalytic properties of the nonthermal plasma combined process which is not affected by sulfur in emission are clarified using numerical simulations and experiments. Innovative and promising marine-engine exhaust gas aftertreatment systems have been developed by collecting and unifying various kinds of new knowledge concerning plasma environmental improvement technologies. Final objective of this study is to realize a marine diesel engine system with ultra-low PM (particulate matter) and NOx emissions, and contribute global environmental protection.
