【摘 要】According to the geometric parameters, test data and boundary
conditions of an 1.8L naturally aspirated gasoline engine, one -dimensional
simulation models were modeled .On the basis of simulation results of
gasoline engine, pumping loss characteristic, thermal efficiency
characteristic and BSFC characteristic of part load were analyzed.The
results show that pressure drop at throat increases , pumping loss raises,
indicated effi-ciency decreases and fuel economy deteriorates with the
decrease of the load , which means that reducing pressure drop at throat is
important to reduce pumping loss , increase thermal efficiency and reduce
BSFC .% 根据某型号1.8L 自然吸气汽油机的几何参数、试验数据和边界条件，建立一维仿真模型，分析了汽油机部分负荷的泵气损失特性、热效率特性和油耗特性，结果显示部分负荷时随着负荷的降低，节气门处压力损失增加，泵气损失增加，指示热效率降低，燃油经济性恶化，表明降低节气门处的压力损失对降低汽油机的泵气损失，提高热效率，降低燃油经济性有重要意义.

摘 要 本文对发动机风扇部件性能衰退的诱因进行分析，得到导叶调整不到位和叶片粗糙度增大是影响风扇性能退化的两个关键因素。通过流场仿真技术研究了两种因素对性能参数的影响，以及特性曲线的变化。
并以建立的发动机稳态模型为基础，通过修改风扇特性曲线，研究了风扇性能退化后对发动机整机性能
的变化。可以为风扇性能及整机衰退研究提供参考。
