2 柴油机的主要性能参数图2.1中,上图的横座标是距离,中图和下图的横座标是容积。通过这种解释,读者一定能把活塞移动距离的概念和气缸容积变化的概念联系起来。 2.1 压缩比活塞从下止点移动到上止点,即走完一
2 main performance parameters of diesel engine Figure 2.1, the abscissa of the figure is the distance, the abscissa of the figure and the figure is the volume. Through this explanation, the reader must be able to relate the concept of piston travel to the concept of cylinder volume change. 2.1 compression ratio piston moves from bottom dead center to top dead center, namely finish one
