After the working phase the cylinder is emptied of exhaust and the process starts again.
后阶段的工作缸是空的废气和进程再次启动。

Theoretically, it is proved that for both these engines, the properties of two-phase flow in nozzle can be analysed with a common combined parameter which is equivalent to exhaust velocity.
Research has believed that veining in admission and exhaust passage of diesel engine cylinder head may mainly be caused by crack of sand core occurring in high temperature phase change expansion.
