Hi Silverstar,
hab ein wenig bei S2KI gestöbert und habe was gefunden:

There are 3 octane ratings that I am aware of: RON (Research Octane Number: used everywhere except the USA) MON (Motor Octane Number) (RON+MON)/2 (Pump Octane Number: used in the USA) MON and RON both measure the gasoline resistance to auto ignition, albeit under different conditions. From this perspective the method used in the USA is the more complete. There is a rough equivalence between systems, with the stress on rough. This is not a question of units but measurement methods! I think there is a misconception in this thread that somehow Octane ratings relate to fuel stored energy. This is not so. What happens is that modern engines have detonation sensors that can detect that the gasoline is pre-igniting, adjusting timing as a result to prevent damage. As timing is advanced, power is lost and thus the lore about lower octane = less power. Note that for auto-ignition to occur a lot of things must happen simultaeously. If it's cold enough, if the engine is not under severe load, you most likely can use a lower octane fuel with no detonation. And you certainly cannot expect to get more power just because you're using a higher octane fuel. As for engine versions there are 3 that I am aware of: F20C (JDM, higher CR, 250PS=247HP, Reco: 100RON) F20C1 (OZ, USA, ??, 240PS=237HP, Reco: 95/96 RON) F20C2 (most if not all of Europe, 240PS=237HP, Reco: 98RON) No one could determine for sure what the differences are between F20C1 and C2. |
