Outline of Final Research Achievements

PM (particulate matters) which is the toxic substance is contained in the exhaust gas from a diesel engine. Therefore, utilization of the reduction system for marine diesel engine is required. In this study, high frequency power supply and the filter unit have been examined, respectively. A ferromagnetic metal is applicable to the PM trapping filter by using quasi variable capacitor. As a result, improvement in power supply efficiency has been proved because a rapid heating and a high temperature heating were achieved. Moreover, removal of PM and operational stability of the system have been confirmed.
