난이도 & 준비물

증상

I know that steam engines are considered to be old fashioned, impractical and rarely used. Why are they considered impractical therefore rarely used? How exactly might a steam engine work to power a car as a replacement for the internal combustion engine? I have made the assumption that it is possible.

처리 내용

In the early automotive days, steam-powered cars were more common than anything else. Disadvantages of steam power for automotive use, as compared with the internal combustion engine: Inefficiency. In an internal combustion engine, chemical energy is converted directly to mechanical energy in the form of expanding gas combustion products. Conversely in a steam engine, there is the extra step of transferring heat energy from combustion to superheat water, and then the expansion of the superheated water to steam to produce mechanical energy. Typically any conversion of energy from one form to another will incur energy losses. Weight. External combustion and the extra energy transfer to water/steam requires extra hardware. This all adds significant weight to produce the same amount of power Slow start. Even with a flash boiler, it will be necessary to wait some time for the water to be heated to the point where it can produce useful mechanical energy. In the early days of internal combust
