2． A charge of fresh air is drawn or pumped into the engine cylinder and then compressed by the moving piston to very high pressure新鲜空气被吸入或注满主机气缸，这时通过活塞的压缩产生很大的压力3． The operation between two injections is called a cycle, which consists of a fixed sequence of events工作周期是指在两次喷油之间的过程，它是由一个固定顺序组成4． The exhaust ports are uncovered also. Pressurized fresh air charges into the cylinder, blowing out any residual exhaust gases from the last stroke through the exhaust port.排气口打开，压缩空气的新鲜空气充入到气缸;来自最后一个冲程通过排气口排出一些残留废气。

5． In the two-stroke engine ,each revolution of the crankshaft makes one power or working stroke , while in the four-stroke engine , it takes two revolutions to make one power stroke.在二冲程柴油机中，曲轴每转一周就做一次功或一个工作行程：而在四冲程柴油机中，曲轴每转两周才做一次功Lesson51． We found NO.2 cylinder knocking.我们发现2号缸发生敲缸2． All the piston rings are worn on the same side .推荐精选所有的活塞环都在同一侧被磨损3． This liner was renewed lately. But it is already worn out about 5 hundredths of one millimeter.这个衬套前不久刚更换的，但是它每毫米已经被磨损了百分之五4． The white metal of the lower half of the crosshead bearing is squeezed out.十字头轴承下半部分的白合金被挤出来。

5． The piston is a little bit inclined.这活塞有点倾斜6． Cylinder clearance is too large.气缸间隙太大7． The cylinder cover starting valve leaks.汽缸盖上的气动阀泄露8． The cylinder oil one-way valve leaks.汽缸油单向阀泄露9． A bedplate must both be strong enough and sufficiently rigid.一个机座必须拥有足够的强度和硬度Lesson6１．By our estimation, there will be about one hundred and twenty tons of oil fuel oil left on board, and we are going to store it in one tank.据我们的估计，大约一百二十吨的燃油将留在船上，我们将它们储存在一个油柜里2．The fuel oil requires treatment before passing to the engine.燃油在进入主机之前需要被处理。

3．A typical fuel injector consists of two basic parts , the nozzle and th。
