英语翻译
工作原理的不同,不论是二种程发动机还是四冲程柴油机,都要经过进气、压缩、燃烧膨胀、排气四个工作过程,才能完成一个工作循环.
所不同的是：
1、在四冲程发动机中,曲轴每旋转两圈,活塞往复移动两次,每四个冲程完成一个工作循环.而在二冲程柴油机中,曲轴每旋转一圈,活塞往复移动一次,每二个冲程完成一个工作循环.
2、二冲程柴油机与四冲程柴油机每完成一个工作循环,其进、排气门或进、排、扫气口都只开启和关闭一次,但其开启和关闭的时间周期不同.
3·理论上讲,二冲程柴油机所能产生的功率应等于相同工作容积四冲程柴油机所产生的功率的两倍.
4·由于二冲程柴油机的换气,有一部分可燃混合气随废气一同排出,因而燃油和润滑油消耗量都大.
5、由于二冲程发动机作功冲程频率大,故工作较平稳.
总体布置的区别
1、四冲程发动机具有一套复杂的气门式配气机构,由凸轮轴控制气门定时开启、关闭,来完成进、排气过程.而二冲程柴油机它是利用活塞控制排气口和扫气口的开闭来完成扫气、排气过程的.
2、二冲程发动机的扫气、排气都在活塞下止点附近进行.而四冲程发动机的配气机构设置在气缸盖上.
3、二冲程柴油机大多采用曲轴箱扫气,四冲程发动机曲轴箱有压力油道或油管.
4、二冲程发动机的气缸盖结构简单,没有进、排气口及配气机构,也没有润滑油道.四冲程发动机的气缸盖是一个非常复杂的部件.
5、二冲程发动机的活塞环只有气环,没有油环.而四冲程发动机的活塞环既有气环,也有油环.
6、二冲程发动机的活塞裙部相对于四冲程发动机的活塞裙部要长些.
希望不要用翻译软件啦 我想看看用我们的语言怎么表达

The working principle of different,both two or four stroke diesel engine process,want to pass intake,compression,burning expansion,exhaust four working process,to complete a work cycle.
Different is:
1,in four stroke engines,crankshaft each rotation two laps,piston mobile twice,every four stroke to complete a work cycle.And in two stroke diesel,crankshaft each a whirl,piston mobile time,every two stroke to complete a work cycle.
2,two stroke diesel and four stroke diesel every complete a work cycle,the intake and exhaust the door or into,platoon,carbon monoxide and only opening and closing time,but the opening and closing of the different time periods.
3 · theory,two stroke diesel can produce power should be equal to the same volume four stroke diesel produces two times the power.
4 · because two-stroke diesel engine take a breath,it is a part of the mixture with the waste gas from together,and fuel and oil consumption.
5,because two stroke engine function stroke frequency big,the work is relatively stable.
The difference between the general layout
1,four stroke launched a complex valve type machines with gas authority,the camshaft control valve timing open and close,to complete the intake and exhaust process.But two stroke diesel is to use the piston control vent and sweep the body to complete and shut gas,exhaust the process of.
2,two stroke engines,exhaust gas and in the piston BDC near.And four stroke engines with gas institutions set in the cylinder.
Three,two stroke diesel is used mostly crankcase and gas,and four stroke engines crankcase oil pressure word or tubing.
4,two stroke engine cylinder head of simple structure,no into,vent and with gas institution,is no lubricating oil way.Four stroke engines of cylinder head is a very complex components.
5,two stroke engine piston ring only gas ring,no oil rings.And four stroke engines of both the piston ring ring,also have oil to ring.
6,two stroke engine piston skirt relative to four stroke engines of the piston skirt should grow some.
