Meaning of octane. An octane rating, or octane number, is a standard measure of an engine or aviation gasoline capability against compression. Finland: 95 and 98 (RON), advertised as such, at almost all gas stations. Similar to an AKI, it has two different ratings, although it is referred to only by the lower of the two. The Gas which has been advertised 97 RON has been dropped in 2014 and renamed 95+. 98 and 100 RON (Shell V-Power Racing) has been dropped in late 2009. This is important to know when choosing a fuel for a particular engine. [8] The second is the "aviation rich" rating and corresponds to the octane rating of a test engine under forced induction operation common in high-performance and military piston aircraft. South Korea: "regular" unleaded fuel is 91~94 RON, "premium" is 95+ RON nationally. Netherlands: 95 RON "Euro" is sold at every station, whereas 98 RON "Super Plus" is being phased out in favor of "premium" fuels, which are all 95 RON fuels with extra additives. The premium petrols are generally ordinary fuels with additives, that do not really change the octane value. "Regular" unleaded fuel is 95 RON; "Premium" fuel is rated at 97 RON (Shell's V-Power Racing is rated minimum 97 RON). In the, China: 92 and 95 (RON) (previously 93 and 97. See the table in the following section for a comparison. For example, gasoline with the same knocking characteristics as a mixture of 90% iso-octane and 10% heptane would have an octane rating of 90. high-octane definition: 1. What does octane mean? This difference between RON and MON is known as the fuel's sensitivity,[5] and is not typically published for those countries that use the Anti-Knock Index labelling system.

Other options are "Pertalite", rated at 90 RON, "Pertamax", rated at 92 RON and the "Pertamax Plus" rated at 95 RON, and "Pertamax Racing", a 100 RON fuel sold in few stations. The highest grade available is 97 RON which is only sold by a few stations in Yangon and Nay Pyi Taw (e.g., PTT, MMTM, Petrotrans). Octane rating does not relate directly to the power output, instead octane rating simply refers to gasoline capability against compression. [citation needed] Pilots are taught in primary training to avoid settings that produce the highest exhaust gas temperatures, and run the engine either "rich of peak" (more fuel than can be burned with the available air) or "lean of peak" (less fuel, leaving some oxygen in the exhaust) as either will keep the fuel-air mixture from detonating prematurely. Octane numbers are based on a scale on which isooctane is 100 (minimal knock) and heptane is 0 (bad knock). [citation needed], Because of the high cost of unleaded, high-octane avgas, and possible increased range before refueling, some general aviation pilots attempt to save money by tuning their fuel-air mixtures and ignition timing to run "lean of peak"[clarification needed]. Octane ratings are not indicators of the energy content of fuels. They also evaporate away much more easily than heavier, lower-octane fuel which leads to more accumulated contaminants in the fuel system. (See Effects below and Heat of combustion). Colombia: "Ecopetrol", Colombia's monopoly of refining and distribution of gasoline establishes a minimum AKI of 81 octanes for "Corriente" gasoline. Additionally, engines designed to work with higher octane also burn the fuel more completely — meaning less harmful emissions in exhaust. Another type of octane rating, called Observed Road Octane Number (RdON), is derived from testing gasolines in real world multi-cylinder engines, normally at wide open throttle. Aircraft engines run at relatively low speeds and are "undersquare". Total and Shell stations only sell RON 92 and 95 gasoline. Have you ever seen your pet sploot?

Most refiners produce and market more than one grade of motor gasoline, differing principally in their anti-knock quality. 96 RON is also available at a large number of gas stations but 95 RON is more preferred because it's cheaper and performance differences aren't very wide and noticeable. Though there is a scientific definition for this word, it can be used in everyday talk. Fuels with high octane numbers are used in high performance gasoline engines. The Octane rating is the ability of the fuel to resist engine knock – the engine pinging or rattling sound that comes as a result of premature ignition of the compressed fuel in one or more cylinders.

[6], The evaluation of the octane number by the two laboratory methods requires a standard engine, and the test procedure can be both expensive and time-consuming. Pakistan: 3 types of fuel available. 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 or detonation. All variants are unleaded.

A selection of brands offers >=100 options, under trademarked names. Aircraft also typically have dual "redundant" ignition systems which are nearly impossible to tune and time to produce identical ignition timing so using a lighter fuel that's less prone to autoignition is a wise "insurance policy".
