摘　　要：本文通过对摩托车发动机摩擦损失的分析,找到了降低和进而预测摩擦损失的途径,同时建立了预测发动机动力性、经济性指标的计算模型。该计算模型提供了预先估计发动机性能的简便而有效的方法,通过实机测试,证明是合理的有一定参考价值。By analysis of the friction loss of motorcycle engine, we found the way to reduce the friction loss, and set up the calculation method to predict the friction loss of motorcycle, power character of motorcycle and economical efficiency index. The calculation method offer us an effective way of pre-estimating engine performance simply and effectively, which is testified to be rational by real trial on engines, and be valuable for us to use for reference in design from now on.

关 键 词：摩托车 发动机 摩擦损失 平均有效压力 性能预测
