项目摘要

1.Investigation of construction and material for a diesel particulate filter (DPF)On the basis of a cylindrical type of DPF which had been developed in 2002, a special metal fiver has been applied for the new model of DPF with improvement of the construction. The new model of DPF enables to trap the particulate matter (PM) from diesel engine efficiently with suppressed back pressure of exhaust gas.2.Development of a novel high frequency inverter for high frequency power supply of induction heatingA new method of design procedure of a complex resonant full bridge type zero current switching (ZCS) high frequency inverter which provides high amplitude of output current with suppressed switched current in low input voltage has been established. A digital gate pulse control circuit has been also developed and all switching modes form transient to steady state condition can be switched in ZCS operation.3.Experiment of PM reduction from diesel engine and regeneration of DPF by induction heatingThe PM exhausted from diesel engine is trapped by DPF. The DPF is regenerated by induction heating repeatedly. In the results, the optimum heating temperature for regeneration of the DPF in connection with required electric energy has been cleared. Through the experiments, PM has been trapped certainly and regeneration of the DPF by induction heating has been realized.

1.柴油机颗粒过滤器（DPF）结构和材料的研究新型DPF在2002年开发的圆筒型DPF的基础上，采用了特殊的金属过滤器，并对结构进行了改进。新型号的DPF能够有效地捕获柴油发动机中的颗粒物（PM），同时抑制废气背压。2.开发一种用于感应加热高频电源的新型高频逆变器一种设计程序的新方法复合谐振全桥型零电流开关（ZCS）高频逆变器已经建立，该逆变器可在低输入电压下提供高输出电流幅度并抑制开关电流。还开发了数字门脉冲控制电路，在ZCS操作中可以切换从瞬态到稳态的所有切换模式。3.柴油机PM还原和感应加热DPF再生实验柴油机排出的PM被捕获通过DPF。 DPF通过反复感应加热进行再生。结果表明，与所需电能相关的DPF再生的最佳加热温度已经确定。通过实验，PM得到了一定的捕集，并实现了DPF的感应加热再生。
