本发明的催化剂，其特征在于，包含铌的碳氮氧化物。
Specifically disclosed is a catalyst characterized by being composed of niobium oxycarbonitride.
黑碳并不是单独被排放的，它被排放的同时还混合了许多别的物质——比如，有机分子还有各种各样的硫氧化物和氮氧化物。
Black carbon is not emitted alone, but mixed with other things-organic molecules and various oxides of sulphur and nitrogen.
准均质充量压缩点火燃烧(QHCCI)方式占总燃料多数的预混合燃料以稀薄燃烧完成，故可能有很低的排放，尤其是碳烟和氮氧化物。
Quasi homogeneous charge compression ignition (QHCCI) combustion may be with low emissions, especially for soot and NO_X, according as the most fuel which is pre-mixed is lean burnt.
