摘　　要：针对助燃剂的特点,选用二叔丁基过氧化物(DTBP)作为汽油添加剂,按体积分数1‰分别添加到95#和97#汽油,通过发动机台架试验,研究DTBP对燃油经济性、燃烧特性和排放特性的影响。结果表明,DTBP能有效降低95#和97#汽油的油耗率;DTBP在中、高负荷能提高95#和97#汽油缸压峰值,提高燃烧速度;在高负荷能改善CO、HC和NOx排放。Ditert-Butyl Peroxide （DTBP） is chosen as combustion improver additive for gasoline, 1%o volume fraction of which are added to 95^# and 97^# gasoline respectively to study the effect of DTBP on the fuel economy, combustion and emission characteristics of gasoline engine by bench test. The results show that DTBP can increase combustion rate, raise peak cylinder pressure at medium and high load, and hence effectively reduce fuel consumption for both 95^# and 97^# gasoline to different extent; while improve the emissions of CO、HC and NOx at high load.
