Web3 de ago. de 2016 · So, in first part of the "compression" stroke, air is expelled back into intake manifold (so no compression actually takes place), then the valve closes and only the remaining part of the stroke actually compresses. This trick is used in so called "Atkinson cycle" engines that achieve better fuel efficiency at cost of lower power, eg in Prius. WebShort version: higher compression ratio means higher efficiency, so for the same amount of fuel in you can get more useful power out. Long version, which has a bunch of messy thermodynamics behind it. Higher compression means the charge is smaller when the piston is at the top, and that it's hotter and higher pressure during the power stroke.
