Development of a marine diesel particulate filter (M-DPF) applied for high frequency induction heating

Novel marine diesel particulate filter (M-DPF) applied for high frequency induction heating is useful system in which particulate matter (PM) exhausted from marine diesel engine is trapped on the surface of the metallic fiber filter and is effectively burned and regenerated by high frequency induction heating. For efficient PM trapping and regeneration of the DPF, the construction on substance of the filter is crucial importance. From the design point of view, some types of DPF such as cylindrical type and pleated type are experimentally examined for PM reduction system and the performance as DPF is investigated. Trapped PM on the metallic fiber filter is successfully burned off by high frequency induction heating unit which is composed of a new working coil and high frequency power supply.
