Maximum Boost 最优化的增压

perfectturbo

本人从事涡轮增压器的配试及销售，近期发现一本国外工程师写的书，非常有趣，现将中英文内容陆续翻译给大家。这本书对于增压系统的设计、测试以及安装做了详细的描述，希望这些资料让您对增压有更详细的了解。

好了，不罗嗦了，先来一段。。。。

a turbocharger is a simple device. it is nothing more than an air pump driven by energy remaining in the exhaust gases as they exit an engine. of the energy released in the combustion process, approximately one-third goes into the cooling system, one-third becomes power down the crankshaft, and one- third is dumped out the tailpipe as heat.
涡轮增压器是一个非常简单的装置，它不过是一个由流出发动机的废气所驱动的空气泵。在发动机燃烧过程中，大约三分之一进入了冷却心痛，三分之一成为推动曲轴的功，三分之一被作为热量扫出排气管。

it is the last third that we can use to power the turbo. consider that a 200 bhp engine dumps approximately 70 bhp equivalent of raw heat straight out the tailpipe. that is tremendous amount of energy that could be put to better use. by comparison, when was the last time you saw an air fan operated at 70 hourepower? thus, it is not so hard to imagine the turbo's potential for moving huge amounts of air.
我们可以利用的就是最后三分之一来驱动涡轮。想想一个200马力的发动机直接从排气管中扫出大概相当于70马力的热量， 那是可以被更好利用的很大数量的热量。相比之下，什么时候你最近一次见过70马力的空气风扇？ 因此，那不难想象驱动大量空气的涡轮的潜力。

很好啊！！多谢  就是太少了点！

谢谢楼上的鼓励，我希望自己能够坚持下来，在6个月的空闲时间内翻译完这本很有趣的书，请多关注哦。

a turbocharger system consistsof a turbocharger and parts necessary to integrate it into the engine's operation. a turbocharger system is not a simple device. nowhere in these pages, however do i discuss such things as the shapes of vortices created by the tips of the compressor wheel. therefore, you may read on with confidence that this is not an engineering treatise on the mysteries of the inner working of the turbocharger.
一个增压器系统是由增压器和将它与发动机的运转合为一体的其它必要零件组成，增压系统不是一个简单的装置，然而在本书中没有地方讨论像压轮末端产生的涡流形状的问题，因此你就可以带着信心读这本书，这本书不是一本探讨关于涡轮增压器内部工作秘密的工程学专著。

the  specific contribution i intend this book to make is as a handbook on the partical aspects of applying the turbocharger to the internal combustion engine. the turbocharger has, pure and simple, greater potential for improving the power output of an engine than any other device.
我所打算的这本书能够做出的特殊贡献是作为一本将增压器应用到内燃机方面的手册，增压器相比其它的装置，有单纯的、简单的、更大的潜力提升发动机的功率输出。

what the turbo is, how it does its magic, and the equipment necessary to civilize it are the focal points around which this book is written.
涡轮增压是什么，它如何施展他的魔力以及这个装备必须去优化它是写这本书所关注的焦点。

1. An engineering look at the basics
基础原理的工程学看法

the power-enhancing capability of the turbocharger has been most thoroughly demonstrated by the Grand Prix racing cars of the 1977 to1988 era of Formula 1.
涡轮增压器的功率提升能力已经被最彻底的被从1977年到1988年的F1汽车大奖赛赛车所证明。

The comparison of the powfer output of a top fuel dragster with that of a Formula 1 race car will establish the turbo's credentials. Current output of top fuel cars with 500 cid(cubic inch displacement) engines is suggested to be in the 5000-6000 bhp range, which caluates to around 10 bhp per cid.  These numbers are not favorable compared to the 1200-1400 bhp, 90 cid qualifying engines of the 1987 Formula 1 cars. These outpus represent 14-15 bhp per cubic. That the champion is crowned is obvious even to casual observers. However, for the potential street turbo user, large questions remain.  Answers to these questions will indicate why turbocharging is equally useful to the fast car entusiast who relies on his car for daily commuting, to the racer, and even to the outer firnge of street power freaks.
通过一个Top fuel dragster 与Formula1 赛车的功率输出比较将会确立涡轮增压的信任。 现在500立方英寸排量发动机的top fuel 汽车功率输出被建议在5000-6000马力的范围，每立方英寸的功率输出计算出是10马力。 这些数据跟1987年Formula 1 90立方英寸具有资格的发动机功率1200-1400马力相比并不令人喜欢，F1发动机的功率输出代表着14-15马力/立方英寸，对于行业外的观察来说谁能得冠军是很明显的了。然而，对于潜在的普通增压使用者，仍然有很多问题，这些问题的答案将会指出为什么涡轮增压同样有用，对于用车来作为日常通勤用车的快车热衷者，对于赛车手，甚至对于街头功率迷们。

perfectturbo

why does the turbo produce more power than other forms of enhancement? The power output potential of any supercharger is measured by amount of airflow the device after factoring out the power required to drive it and the extent to which it heats up the air while creating the flow and pressure. While it might appear that the turbo does not drain power from the engine, since the exhaust energy is lost anyway, this is far from correct. Heat and airflow drive the turbine. When air is forced through the turbine section of a turbo, reduced-flow areas inherent in the design create back pressure.
为什么涡轮增压的功率提升要比其他形式的提升大呢？任何一个机械增压的潜在功率输出通过空气流量被测量，这个装置需要被驱动，当它创造空气流动和压力时也会加热空气，而那就可能会发现涡轮增压没有从发动机吸取能量， 因为废气能量总是要丢失的，这种理解离是不正确的，高温高压的废气驱动涡轮，当空气被通过涡轮部分的驱动吸入时，在设计中固有的流动降低区就会产生一个背压。
