我不会,只是知道这些都是改车的东西来的。
Google找来的,大概是:
When the piston is at the lowest point, that's called Bottom Dead Center. That's where the cylinder volume is greatest. ... If an engine has a high compression ratio, it means that a given volume of air and fuel in the cylinder is being squeezed into a much smaller space than an engine with a lower compression ratio.
翻译为华语大概是:
当活塞处于最低点时,称为下止点。 那是气缸容积最大的地方。 ...如果发动机具有较高的压缩比,则意味着气缸中的给定体积的空气和燃料将被压缩到比具有较低压缩比的发动机小得多的空间中。
