An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without detonating. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates gasoline's capability against compression. WebAs pressure is released, the liquid propane vaporizes and turns into gas that is used in combustion. An odorant, ethyl mercaptan, is added for leak detection. (See fuel properties.) Propane has a high octane rating, …
Webspeed comparable to gasoline Fueling time: same as gasoline Pure, 100% ethanol has an octane rating of 113. Adding 10% ethanol to unleaded gasoline raises the octane by 2 - 3 points. Ethanol is used in racing because of these high-performance characteristics. WebSufficient knocking resistance, octane rating, is essential for proper operation of spark-ignition engine.
