| Pour les sceptiques, un extrait du manuel des MkIII (c'est la même chose pour les autres si je ne m'abuse) : "Recommended Fuel The "Spitfire Mk. III" engine is designed to operate on fuels having a minimum octane rating of 97 (Research Method). Using fuel of this, or higher rating, the static ignition timing should be 60 B.T.D.C. Where such fuels are not available and if, therefore, it becomes necessary to operate on fuels of lower or unknown rating, the static ignition timing must be retarded just sufficiently to prevent audible detonations (pinking) under all operating conditions. Failure to do so may result in serious damage to the engine." |
