Subsequently the charging shaft must be latched to top dead centre with the charged closing spring (Fig. 15).

随后，储能轴和已储能的合闸弹簧停在上中心点位置(图15)。

Note that the compression ratios shown above reflect the expansion ratio, which is the ratio of the combustion chamber volumes when the piston is at Bottom dead centre and Top dead centre.

请注意，压缩比上述反映膨胀率，这是燃烧室的量的比例时，活塞的下死顶死中心，中心会显示。

The first sensor monitors the camshaft position delivering one pulse per revolution which corresponds to the top-dead-centre (TDC) position of one of the pistons.

第一个传感器用来监视每次旋转时释放一次脉冲的机轴位置，该位置相当于某一活塞上止点的位置。
