查询词典 trunk engine

Using the 294cc rotary engine, it can influence the maximum rpm and power of the engine output under the terms of using all kinds of length intake. Then it can find out the best length of intake of the rotary engine. In addition, under the terms of space limit of intake, it can influence the maximum rpm and power of the engine output when the intake is forced to limit on a certain length. To install a resonance in the intake system, according to the equation of Helmholtz, it can design the all kinds of size of the resonance. Using to change the volume and geometirc form of the resonance, it can find out the maximum rpm and horsepower of engine output in order to reduce the influence of the variation of engine intake length. Under the verification of the experimental result, this simple device can increase the rpm and horsepower of the rotary engine obviously to achieve the output performance that the engine requires to supply. Such the revisal of intake need the lower cost but it can obtain very obvious efficiency. It is a very feasible way.

藉由一具294cc的飞行器引擎，在使用各种不同长度进气道的条件下，对引擎所能输出的最大转速及马力有一定的影响，藉此找出该具引擎的最佳进气道长度；此外，在进气道因空间限制的前提下，进气道被迫只能局限某个长度以下时，在这种条件下，引擎所能输出的最大转速与马力等相关性能会随之受到影响，在进气系统加装一个共振腔，配合Helmholtz的方程式，设计出各种共振腔各部位的尺寸，利用改变共振腔的体积与几何形状，可以寻求增加引擎转速与输出马力的最大值，藉此降低进气长度变化所带来的影响，在实验结果的验证下，此一简单的装置可以明显的增加引擎转速与马力，以达到对引擎所需的输出性能要求，这样的进气系统修改所需的费用极低，但却可获得很明显的功效，是十分可行的方式。

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。
