A particulate matter (PM) reduction system exhausted from marine diesel engine has been investigated on the basis of high frequency induction heating technique. The proposed PM reduction system employs two sets of induction heating units made of diesel particulate filter (DPF) and they are operated alternately to regenerate the metallic filter parts. The metallic filter generates heat with an eddy current when a high frequency current is supplied to the working coil to heat the filter to a temperature of at least 600°C. Then the particulate matter trapped by the filter is burned out. The improved structure of the DPF is introduced and experimented using a diesel engine generator. The effectiveness of the DPF system is verified through the experiment.
