怎么会没关系?basically air+fuel=power,如果马力不足就要input更多的fuel. fuel可产生的能量多少全取决于octane的多少. 87号的油用在91标号的车里一点都不经用. 6 y# I! s4 w- ?4 U) z

Higher compression ratio gives more power, but it needs higher octane to prevent pre-ignition.. E* V8 f& b- M) M Z0 ^! q
There is no absolutely advantage of putting higher octane fuel into a low compression enginee but it won't hurt it. |
