    • Delivery of metallic combustion catalysts to internal combustion engines and other combustion devices is improved by dosing units that have the ability to effect the slow and positive supply of metallic additives, including platinum and/or cerium containing catalyst compositions, to fuel. The invention provides additive dosing materials and methods for simply and effectively supplying catalytic metal fuel additives to fuel in suitable low concentrations as are effective. The dosing units can be used with devices made to contact diesel fuel. In one approach, a catalytic metal additive concentrate (CMAC) is prepared in normally solid, semisolid or viscous form. The CMAC will preferably be encapsulated with a solid polymer. The encapsulation can be accomplished by embedding or dispersing the CMAC in a suitable polymer. If desired, the CMAC can be dispersed in one polymer and then the resulting composite can be embedded in the same or a different polymer. In an alternative form, a dosing unit can comprise a semisolid CMAC, which could be similarly held in contact with flowing fuel.
    • 将金属燃烧催化剂递送到内燃机和其它燃烧装置通过配量单元得到改进,所述给料单元具有将燃料和金属添加剂(包括含有铂和/或铈的催化剂组合物)缓慢且正向供应的能力。 本发明提供添加剂剂量材料和方法,以有效的方式简单有效地将催化金属燃料添加剂以合适的低浓度供给燃料。 计量单元可与用于接触柴油的设备一起使用。 在一种方法中,以通常固体,半固体或粘稠形式制备催化金属添加剂浓缩物(CMAC)。 CMAC优选用固体聚合物包封。 封装可以通过将CMAC嵌入或分散在合适的聚合物中来实现。 如果需要,CMAC可以分散在一种聚合物中,然后所得到的复合材料可以嵌入相同或不同的聚合物中。 在替代形式中,给药单元可以包括半固体CMAC,其可类似地保持与流动的燃料接触。
