四. Translate the following sentences into English. (20分)
1 润滑系的机油泵从油底壳抽出机油并把机油输送给发动机的所有工作部件。

机油从油底壳流进流出.因而在油底壳和发动机的工作部件之间就有机油定向循环流动。

2大多数活塞由铝铸造而成。

通过连杆的作用，活塞把可燃混合气燃烧产生的力传递给曲轴，带动曲轴旋转。

3 柴油机发动机根据喷油方法不同，活塞头部可以形成全部燃烧室，也可以是燃烧室的一部分．
4 在新型发动机上，每个活塞有三个活塞环。

（在老式发动机上，每个活塞有四个甚至五个活塞环）环的内侧装在活塞的环槽里，环的外表面紧压在气缸壁上。

4As the camshaft rotates, the lobe, or high spot of the cam, pushes against parts connected to the stem of the valve. This action forces the valve to move downward. This action could open an inlet valve for an intake stroke, or open an exhaust valve for an exhaust stroke.
5 It is apparent from this description that the exhaust valve stays open for a short period of time during which the intake valve is also open. In other words, the end of the exhaust stroke and the beginning of the intake stoke overlap for a short period of time. This is called valve overlap. Valve timing
and valve overlap vary on different engines.

1 The oil pump in the lubricating system draws oil from the oil pan and sends it to all working parts in the engine. The oil drains off and runs down into the pan. Thus, there is constant circulation of oil between the pan and the working pats of the engine.
2 Most pistons are made from cast aluminum. The piston, through the connecting rod, transfers to the crankshaft the force created by the burning fuel mixture. This force turns the crankshaft.
3 In diesel engines, the combustion chamber may be formed totally or in part in the piston crown, depending on method of injection.
4 In modern engines, each piston has three rings. (Piston in older engines Gas Rings sometimes had four rings, or even five.) The inside surface of the ring fits in the groove on the piston. The ring's outside surface presses against the cylinder walls.
5 The connecting rod little end is connected to the piston pin. A bush made from a soft metal, such as bronze, is used for this joint. The lower end of the connecting rod fit the crankshaft journal. This is called the big end.
