固态氨与尿素喷射控制系统对柴油机氮氧化合物排放影响对比研究

Comparative Research of NOx Emission Efficiency in Diesel Engine between Solid Ammonia and Urea Injecting System

文章介绍了一种向柴油车排气管中直接喷射氨气的固态氨喷射控制后处理系统,通过发动机稳态循环ESC、瞬态循环ETC、世界统一瞬态循环WHTC实验[1]:对比固态氨喷射系统与尿素喷射控制SCR后处理系统[2]对氮氧化物转换效率[3]的影响。研究结果显示固态氨喷射系统在WHTC瞬态循环中,氮氧化合物的转换效率比尿素喷射控制系统高26%。

The article Introduced ammonia delivering system which dosing ammonia gas into selective catalyst reduction system directly,De-NOx efficiency compared between ammonia delivering system and urea injecting system according to ESC、ETC、WHTC test cycle.Research showed ammonia delivering system increase 26%De-NOx efficiency compare to urea injecting system.
