摘要:
采用主成分分析法，研究了汽油12种理化特性对整车新欧洲驾驶循环(NEDC)下经济和排放性能的影响，发动机为气道喷射汽油机．结果表明：汽油12种理化特性可降维为3个主成分，第一主成分得分与蒸气压呈负相关，与密度、初馏点、5%蒸发温度(T5)、10%蒸发温度(T10)、终馏点、芳烃含量和研究辛烷值(RON)呈正相关．第二主成分得分与重芳烃含量和90%蒸发温度(T90)呈负相关．第三主成分得分与烯烃含量呈正相关．提高燃油的蒸气压，降低燃油的密度、初馏点、T5、T10、芳烃含量、终馏点和RON，可以降低车辆在市区驾驶循环(UDC)和NEDC下的CO2排放(最高降幅为18.14%)以及车辆在UDC下的百公里油耗(最高降幅为14.80%)．降低燃油的烯烃含量可以降低车辆在UDC、市郊驾驶循环和NEDC下的NOx排放，最高降幅为32.61%．
Abstract:
The principal component analysis method was used to study the comprehensive effects of 12 physical and chemical properties of gasoline on economy and emission performance of a vehicle under new European driving cycle(NEDC). The vehicle has a port-injected gasoline engine. The results show that the 12 physical and chemical properties of gasoline can be reduced to 3 principal components. The score of the first principal component is negatively correlated with vapor pressure，and positively correlated with density，initial boiling point，5% evaporation temperature(T5)，10% evaporation temperature(T10)，final boiling point，aromatics content and research octane number(RON). The score of second principal component is negatively correlated with heavy aromatics content and 90% evaporation temperature(T90). The score of third principal component is positively correlated with olefin content. Increasing the vapor pressure and reducing the density，initial boiling point，T5，T10，aromatics content，final boiling point and RON of fuel can reduce carbon dioxide emissions(with a maximum percentage of 18.14%) of the vehicle under both urban driving cycle(UDC) and NEDC，while reduce fuel consumption per 100 kilometers(with a maximum percentage of 14.80%) under UDC. Reducing the olefin content of fuel can reduce nitrogen oxides emissions(with a maximum percentage of 32.61%) of the vehicle under both UDC and NEDC and extra UDC as well.
