There was an increasing demand for engine power due to industrial development. As early as the 2nd century BC, the ancient Greeks invented an engine that was powered by the reaction from spurting steam; in 1690, the Frenchman Barben invented the first piston steam engine. On the basis of his predecessors' work and with his own hard work and numerous trials and failures, James Watt invented the steam engine with connecting rod, flywheel and centrifugal speed governor in 1782.In 1784, the British government granted a patent to James Watt for producing steam engines, which signified that man had entered the age of the steam engine and also significantly expedited the beginning of the Industrial Revolution in 18th century Europe. By the 1830s, steam engines had been widely used in various sectors such as textile, metallurgy, coal mining and transportation; for example, the American Robert Fulton invented the steamboat and the Englishman George Stephenson invented the steam locomotive.

随着社会的进步，社会由农业时代进入工业时代后，对全用手工操作已十分不满足，人们随着工业发展对动力的需求日益突出，瓦特在前人研究蒸汽的基础上，甚至早在公元前二世纪，古希腊人创造的一种利用蒸汽喷射的反作用的发动机，以及1690年法国人巴比首先发明第一台活塞式蒸气机等，刻苦钻研，反复实验，经历无数次挫折和失败，终于在1782年发明了具有连杆、飞轮和离心调速器的双动作蒸气机，使之成为了可以实用的蒸气机。1784年英国政府授予瓦特以制造蒸气机的专利证书，这标志着人类进入了蒸气机时代，有力地促进了欧洲18世纪的产业革命。

The paper presents a way that on a diesel engine the fuel ethanol is used blended with gasoline as its additive. On the base of analyzing the physical, chemical and mixing proportion characteristics of ethanol-diesel-gasoline blended fuel, combustion characteristic and the effect on diesel engine performance using the blended fuel with different proportional component are studied on a 135 diesel engine. At the same time, the effect on the diesel engine performance and combustion characteristics using the blend fuel are also studied under different diesel engine parameter.

The possiblehost objective reason all is very many, but, our country numericalcontrol engine bed function part development backwardness -- varietyfew, unit technical level low, performance quality insufficientlystable, the cost stays at a high level, the delivery insufficientlywas prompt and so on -- not to be able to satisfy the numericalcontrol engine bed main engine product need to develop, had noalternative but to say was most direct, the most main reason, Becauseall numerical controls engine bed all is by each kind of function part(including host 轴头, straight line rolls guide rail, ball bearingguide screw vice-, numerical control tool rest, knife storehousemanipulator, rotary table, numerical control servosystem, surveyfeedback as well as safe protective equipment and so on), the functionpart which on foundation rack and so on the lathe bed, column thecollection attire becomes is the numerical control engine bedimportant component, moreover is the indispensable part.

可能主客观原因都是很多的，但是，我国数控机床功能部件的发展落后──品种少，单元技术水平低，性能质量不够稳定，成本居高不下，交货不够及时等──满足不了数控机床主机产品发展的需要，不能不说是最直接、最主要的原因，因为所有的数控机床都是由各种功能部件（包括主轴头、直线滚动导轨、滚珠丝杠副、数控刀架、刀库机械手、回转工作台、数控伺服系统、测量反馈以及安全防护装置等）在床身、立柱等基础机架上集装而成的，功能部件是数控机床的重要组成部份，而且是不可或缺的部份。

So ,the temperature is quite essential for an engine to produce power .No engines can work well without suitable operating temperatures .If the engine runs too hot ,it may suffer form pre-ignition,while the air-fuel change is ignited prematurely from excessive combustion chamber temperature.Viscosity of the oil circulating in an over heating engine is reduced.Hot oil also forms varnish and carbon deposits may be drawn into the combustion chamber where it increases HC emission.This also causes poor performance and premature wear ,and may even result in engine damage.What is more,the behavior of the metals at excessively high temperature also differs from that at normal temperatures and can produce a condition in which the metal deforms slowly and continuously at a constant stress,If the engine runs too cold, the fuel will not vaporize properly.If liquid fuel reachees the cylinders,it will reduce lubrication by washing the oil from the cylinder walls and diluting the engin oil.This causes a loss ofperformance, an inrease in HC emissions, and premature engine wear.

所以，温度是很有必要的引擎来产生电力，没有引擎，可以工作，如果没有合适的操作温度，如果发动机运行太热，它可能遭受的形式预点火，而空气燃料的改变是点火过早过量燃烧室temperature.viscosity的石油流通的过度加热发动机是reduced.hot油价也构成了清漆和碳存款可能会被拖入燃烧室而增加hc的emission.this也造成业绩不佳和过早磨损，甚至可能导致发动机damage.what更重要的是，行为的研究金属在过高的温度也有不同，在正常温度下，可以达到的一个条件，其中金属变形速度缓慢，不断在恒应力，如果发动机运行太冷了，燃料价格将不会汽化properly.if液体燃料reachees气瓶，将减少润滑洗油从气缸壁和稀释器oil.this造成损失ofperformance ， inrease在hc排放，发动机过早磨损。
