摘要
介绍了降低柴油机排气污染的3种措施,重点介绍了油溶性碱金属、碱土金属、过渡金属、稀土元素等有机金属化合物类有灰型促燃剂和有机过氧化物、硝基化合物、酯类、醚类、酮类等无灰型促燃剂的国内外发展概况,指出今后应开发具有清净、分散、促燃等多种功能的柴油添加剂。
The article introduces the methods for reducing emissions from diesel engines by improvement of internal structures of diesel engines or treatment of exhaust gas or enhancement of diesel fuel quality. The method of enhancement of diesel fuel quality includes optimization of petroleum refining processes and usage of additives. The article summarizes the development and application prospects of different diesel improvers such as oil - soluble organo - metallic complexes of alkali, alkaline, transient and rare earth metals and ashless combustion improvers like organo - peroxides, nitrates, esters, ethers and ketones. It is emphasized that the necessity of development of multifunctional diesel combustion improvers with performance of detergent, dispersant and combustion promoters.
