尽管柴油机微粒过滤器（DPF）已经商业化生产多年，但仍然存在许多优化活动，特别是在这些过滤器的再生策略领域。已经开发了一种用于获得铁含量为10-15重量%的有机可溶性物质和含有铁添加剂和其它选定物质的组合物的方法。这些有机可溶性物质形成的基础上开发的各种添加剂的燃料载催化剂（FBC）型被动再生的DPF的。为了测试和评估的有效性的再生过程所支持的开发的FBC添加剂，一种新的多阶段程序，包括三个独立的发动机测试，允许全面检查添加剂，已经实施。在此发动机程序中，每种添加剂都按规定的顺序以不同的剂量水平进行了评级。该评级允许在测功机发动机测试条件下对添加剂的操作性能进行可靠的评估。因此，从开发并在发动机台架测试程序中进行评级的各种FB C型添加剂中，选择了最佳的两种添加剂。这些添加剂实现了比来自两个著名制造商的商业添加剂更好的操作性能。我们已经进行的研究提供了FBC添加剂在DPF的有效被动再生支持中的高操作性能潜力的证据。
Even though diesel particulate filters (DPFs) have been in commercial production for many years, there is still much optimisation activity, especially in the field of the regeneration strategy of these filters.A method for obtaining organosoluble substances with an iron content of 10–15 wt% and composition containing iron additives and other selected substances has been developed. These organosoluble substances form the basis for the development of various additives of the fuel borne catalyst (FBC) type for passive regeneration of DPF’s.To test and evaluate the effectiveness of the regeneration process supported by the developed FBC additives, a novel multistage procedure consisting of three separate engine tests, which allow a comprehensive examination of additives, has been implemented. Each additive had been rated in this engine procedure at different dosage levels in a specified order. This rating allowed reliable assessment of the operational properties of the additives under the conditions of dynamometer engine testing.As a result, from a wide range of FBC-type additives developed and then rated in the engine bench test procedure, the best two additives were selected. These additives achieved a much better operational performance than the commercial additives from two of the reputed manufacturers.The studies that we have performed present evidence of the high operational performance potential of FBC additives in the effective passive regeneration supporting of DPF’s.
