A common example of such a machine is the “heat engine” which uses energy in the form of heat to produce mechanical energy. This family includes many members but, the internal combustion engine is one with which we are all familiar. Although this machine is an integral part of our every day lives, its effectiveness in converting energy is far less than we might expect. The efficiency of the typical automobile engine is around 20%. To put it another way, 80% of the heat energy in a gallon of gasoline does no useful work. Although gas mileage has increased, somewhat, over the years that increase has as much to do with increased mechanical efficiency as increases in engine efficiency itself. Diesel engines do better job, but still max out around 40%. This increase is due, primarily, to its higher compression ratio and the fact that the fuel,under high pressure, is injected directly into the cylinder at the top of the compression stroke. Gasoline engines, on the other hand, are limited to lower compression ratios because fuel enters the cylinder prior to the compression stroke.

虽然没分,还是帮你翻翻,也不难.
一个常见的例子是“热机”,它能把热能转换成机械能.这个大家庭包括许多成员,但内燃机是我们大家都熟悉的.尽管它是我们的每一天的生活不可或缺的,但是其能量转换效率却远远低于我们的期望值.典型的汽车发动机的能量转换效率在20%左右.换句话说,一加仑汽油燃烧转换的热能有百分之八十是没有被利用的.尽管一加仑汽油所行驶的里程数在这几年已有所增加,但是从某种程度上讲,机械效率与发动机效率的提升对其里数的提升有着不可忽视的的作用,而两者对其作用是同等的.柴油机效率比较好,但仍然最大的利用效率也只有百分之四十.它的效率的提升从根本上讲是因为柴油机本身的高压缩率以及燃料是在高压情况下被直接注进汽缸顶端.然而汽油机,率压缩是相对有限的,因为燃料必须在压缩冲程前进入气缸.
