Novel marine diesel particulate filter (DPF) which traps particulate matter (PM) exhausted from a marine diesel engine on the surface of a nonwoven fabric metallic filter has been developed. PM trapping characteristics in relation to the PM reduction ratio and pressure loss in the DPF unit have been investigated through experiments on a running diesel engine. Trapped PM was eliminated by high frequency induction heating, effectively regenerating the DPF. The experimental results which show the mutual relation between the pressure losses and PM reduction ratio in the DPF were investigated and estimated on the basis of the DPF unit’s construction.
