汽车英语的论文范文

一、毕业论文的选题选题是论文写作的首要环节。选题的好坏直接关系到论文的学术价值和使用价值，新颖性、先进性、开创性、适用性以及写作的难易程度等。下面重点谈谈选题的原则：1．要客观需要，颇有价值。选题要根据我国经济建设的需要，具有重大的理论和实用价值。例如“企业联盟问题研究”，就是这样。正如一汽集团李启祥副总经理说，我国汽车与国外的汽车竞争，无论是技术、质量、品牌、功能、成本和规模经济等都比不过人家，只能靠一体化，战略联盟，与“大众”合资进入世界大汽车集团，靠国外发展自己。因此，关于战略联盟的研究，既满足了我国经济建设的需要，又具有重大的理论和实用价值。2．要捕捉灵感，注重创新。论文的生命在于创新。创新的含义非常广泛，是指一种新的观点，创立新说，新的论据(新材料)，新的补充，新的方法，新的角度。也有人说创新指研究的内容是新的，方法是新的，内容与方法都是新的。还有人认为创新指独特见解，提出前人未曾提出过的问题，纠正前人的错误观点，对前人成果进一步深化、细化、量化和简化等。由上可见，一篇论文总要有一点创新，否则就算不上真正的论文。创新靠灵感，灵感靠积累。只有在长期的艰苦砥砺中才能偶然产生一点思想的火花，而这稍纵即逝的思想火花就可能变成学术创新的起点。

汽车，即本身具有动力得以驱动，不须依轨道或电力架设，得以机动行驶之车辆。广义来说，具有四轮行驶的车辆，普遍多称为汽车。虽然，长久以来学术各界对“谁是第一位汽车发明者”皆有不同的看法及论述，未有完全一致性的看法，但是，绝大部份学者皆将德国工程师卡尔·本茨视为第一位发明者。美国人亨利·福特首先大量生产平价汽车，是使汽车得以普及化的人。汽车（Car，卡尔·本茨发明）是一种现代交通工具，英文原译为“自动车”，在日本也称“自动车”（日本汉字中的汽车则是指我们所说的火车），其他文种也多称为“自动车”，只有在中国例外。由动力驱动，具有四个或四个以上车轮的非轨道承载的车辆，主要用于：——载运人员和/或货物（物品）；——牵引载运货物（物品）的车辆或特殊用途的车辆；——专项作业。本术语还包括：a）与电力线相联的车辆，如无轨电车；b) 整车整备质量超过 400kg的不带驾驶室的三轮车辆；c) 整车整备质量超过 600kg的带驾驶室的三轮车辆。

Electronic brakeforce distribution or EBD or EBFD is an automobile brake technology that automatically varies the amount of force applied to each of a vehicle's brakes, based on road conditions, speed, loading, etc. Always coupled with anti-lock braking systems, EBD can apply more or less braking pressure to each wheel in order to maximize stopping power whilst maintaining vehicular control.[1][2] Typically, the front end carries the most weight and EBD distributes less braking pressure to the rear brakes so the rear brakes do not lock up and cause a skid.[3]How ABS worksUnder heavy braking, vehicle wheels may lock-up. The anti-lock braking system (ABS) monitors wheel speeds and releases pressure on individual wheel brake lines, rapidly pulsing individual brakes to prevent lock-up. During heavy braking, preventing wheel lock-up helps the driver maintain steering control. Modern ABS has four individual brake lines for each wheel, enabling different braking pressure on different road surfaces. For example, less braking pressure is needed to lock a wheel on ice than a wheel which on bare asphalt. If the left wheels are on asphalt and the right wheels are on ice, during an emergency stop, ABS detects the right wheels about to lock and reduces braking force on the right wheels, helping to avoid lock-up and loss of vehicle EBD worksAs per SAE technical paper #920646 - Buschmann et al. "The job of the EBD as a subsystem of the ABS system is to control the effective adhesion utilization by the rear wheels. The pressure of the rear wheels is approximated to the ideal brake force distribution in a partial braking operation. To do so, the conventional brake design is modified in the direction of rear axle overbraking, and the components of the ABS are used. EBD reduces the strain on the hydraulic brake force proportioning valve in the vehicle. EBD optimizes the brake design with regard to: adhesion utilization; driving stability; wear; temperature stress; and pedal force."EBD may work in conjunction with ABS and Electronic Stability Control ("ESC") to minimize yaw accelerations during turns. ESC compares steering wheel angle to vehicle turning rate using a yaw rate sensor. "Yaw" is the vehicle's rotation around its vertical center of gravity (turning left or right). If the yaw sensor detects more/less yaw than the steering wheel angle should create, the car is understeering or oversteering and ESC activates one of the front or rear brakes to rotate the car back into its intended course. For example, if a car is making a left turn and begins to understeer (the car plows forward to the outside of the turn) ESC activates the left rear brake, which will help turn the car left. The sensors are so sensitive, and the actuation is so quick that the system may correct direction before the driver reacts. ABS helps prevent wheel lock-up and EBD helps apply appropriate brake force to make ESC work effectively.

There will always be that when you own something when you do not think it would be valuable, but also do not see the value of it, but when you lose it when it come to repentance, but that at the moment when the lateness of the hour, too late for regrets and. I now have such a similar week-long automotive engine disassembly internship is over, memories of this time, he reluctantly are true. Wanted to be back in a week ago, then put in every day practice as seven hours to 27 hours use. This is true, this internship opportunities for me are too precious a this internship, I learned about auto engines knowledge, are ever at a lesson on what can not be compared. And I once again felt the profound theoretical and practical combination of the because of the arrangement to the engine of our components are Santana 2000 engine. First of all, for the automotive engine theory of knowledge, I understand that:Santana in Germany Volkswagen Ltd. 1982 products. The company entered Shanghai in 1983, to cooperate with the development of our country has been the development of three generations - four generations of production lines, and in 95 years will be Santana 2000 Electronic Fuel injection system into the main parameters of motor vehicles including technical parameters, the basic parameters, engine and chassis parameters parameters.
