摘要
对某共轨柴油机分别燃用不同混合比例麻疯树果实制生物柴油全负荷速度特性、标定转速及最大转矩转速负荷特性的全球变暖、光化学烟雾、酸化、人体毒性、气溶胶环境排放特性进行了试验研究。结果表明:与石化柴油比较,随着生物柴油混合比例的增加,该机全负荷速度特性下所有转速的光化学烟雾、气溶胶环境排放降低,1 600 r/min以上的全球变暖、酸化、人体毒性环境排放降低;标定转速及最大转矩转速负荷特性下,该机所有负荷的光化学烟雾、气溶胶环境排放降低,75%负荷以上的全球变暖、酸化、人体毒性环境排放降低。
The experimental study on global warming potential(GWP),photochemical ozone creation potential(POCP),acid potential(AP),health toxic potential(HTP),and air quality potential(AQP) of a common rail diesel engine fueled with jatropha biodiesel blends was carried out on the full load speed characteristics and the load characteristics at rated speed and max.torque speed.The results show that when fueled with jatropha biodiesel blends,the POCP and AQP at all speed conditions on the full load speed characteristics decrease with the biodiesel fraction increasing,and in range of speed over 1 600 r/min,GWP,AP and HTP lower,moreover,the POCP and AQP lower on the load characteristics of rated speed and max.torque speed,its GWP,AP and HTP lower at rated speed and max.torque speed under the load over 75 %.
