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 special 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 metallic filter to a temperature of at least 873K. Then the PM trapped by the filter is burn out. The improved type large-sized DPF (Patent Application PCT/JP/2007/054078) has been successfully experimented from the view point of PM trapping and optimum regeneration timing. For PM trapping, the relationship between density of smoke meter and differential pressure change of DPF has been quantitatively studied. The characteristics of DPF has been investigated on the basis of these experiments and verified for usefulness. Furthermore the efficient regeneration method by high frequency induction heating has been clarified with respect to turn number of working coil and filter gap.

研究了一种基于高频感应加热技术的船用柴油机排气颗粒物（PM）减排系统。建议的PM减少系统采用两套柴油机微粒过滤器（DPF）制成的感应加热装置，它们交替运行，以再生特殊的金属过滤器部件。当高频电流被供应到工作线圈以将金属过滤器加热到至少873 K的温度时，金属过滤器利用涡电流产生热。然后，被过滤器捕获的PM被烧掉。改进型大型DPF（专利申请PCT/JP/2007/054078）已经从PM捕集和最佳再生正时的观点成功地进行了实验。对于颗粒物捕集，定量研究了烟度计密度与微粒捕集器压差变化的关系。在这些实验的基础上研究了DPF的特性，并验证了其有效性。此外，还从工作线圈匝数和滤波器间隙的角度阐明了高频感应加热的高效再生方法。
