Is higher octane fuel harder to ignite
WebMar 16, 2024 · The octane number is actually the simple average of two different octane rating methods—motor octane rating (MOR) and research octane rating (RON)—that differ … WebWith lower or higher octane fuel, as the octane number increases, it becomes harder and harder to burn. This helps prevent pre-ignition. Retarding the timing is moving timing closer to TDC towards the end of the compression cycle. Advancing the timing is moving back from TDC, earlier in the compression cycle.

Higher octane ratings correlate to higher activation energies: the amount of applied energy required to initiate combustion. Since higher octane fuels have higher activation energy requirements, it is less likely that a given compression will cause uncontrolled ignition, otherwise known as autoignition, selfignition, pre-ignition, detonation, or knocking. Because octane is a measured and/or calculated rating of the fuel's ability to resist autoignition, …
