摘要: 使用油溶性水杨醛亚胺化合物先与三氯化铈配位,再结合超重力反应工艺,得到了粒径小、分布窄,且在油中稳定分散的纳米二氧化铈(CeO2)微粒;以该纳米微粒的油分散体系为柴油添加剂,通过发动机台架(Phaser140Ti-E30型直列四缸发动机)试验考察加剂前后发动机负荷特性、速度特性及有害污染物排放等指标,结果表明,纳米CeO2柴油添加剂可使内燃机节油最高可达7%左右,同时降低了排放中的总碳氢化合物、颗粒物等有害物质及烟度。

Abstract: Nanoparticulate CeO2 well dispersed in diesel fuel was prepared from oil-soluble salicylaldimine Schiff Base-cerium (III) chloride complexes under higee conditions. The effect of using nano-CeO2 dispersed component as fuel additive on the diesel engine performance and emissions were evaluated on Phaser140Ti-E30 test device with inline four-engine. A fuel saving of about 7% was obtained and the waste emissions including exhaust smoke, total hydrocarbons (THC) and particulate matter (PM) reduced with a nano-CeO2 adding dosage of 50 g/g in diesel fuel.
Key words: nanoparticulate ceria, rare earth, fuel additive, energy saving and waste emissions reduction
