, p3 n) d1 i9 |9 t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.
% C! Z6 L; K" I% N, J" nHigher compression ratio gives more power, but it needs higher octane to prevent pre-ignition.5 S1 c, ?0 l& e
There is no absolutely advantage of putting higher octane fuel into a low compression enginee but it won't hurt it. |
