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.

air+ diesel=more power, but it won't work on a car that is not designed for it.
4 e" L1 @1 W, NHigher compression ratio gives more power, but it needs higher octane to prevent pre-ignition. `0 N2 ~2 }' a, L
There is no absolutely advantage of putting higher octane fuel into a low compression enginee but it won't hurt it. |
