AV Gas as a Common Aviation Fuel.

Of the many fuels that we have, the type to be used on an aircraft depends on the aircraft in question. For instance, Jets use diesel fuels while there are other aircrafts that use AV gas or Mogas. In this article, we will look at AV gas properties and benefits.

Aviation gasoline or AV gas is the type of gas used in piston powered airplanes. It one unique type of aircraft gasoline that has been in use for a long time. The main purpose of the AV gas is to reciprocate piston engines. There are a number of additives that can be found in AV gas such as corrosion inhibitors, icing inhibitors, static dissipaters, color dies, metal deactivators, tetraethyl, antiknock, and oxidation inhibitors.

At standard temperatures, AV gas, is highly volatile and very flammable. As a result, it should always be handled with extreme care for safety. AV gas has the lean, and the rich mixture ratings that are the octane ratings used in defining the different AV gasoline grades.

Gasoline fuels are mostly prepared from hydrocarbons the most common being iso-octane. Iso-octane has excellent antiknock properties. The fuels that possess similar antiknock properties to those of iso-octane are given a rating of 100. Heptane is one other hydrocarbon that when mixed with a given amount of iso-octane, it may be used for fuel rating.

In recent times, lead additives, and other necessary additions result to a high engine power before detonation. This signifies that the incorporation of lead in aviation fuel essentially makes the engines to perform better. The fuels air ratio is also a significant factor in the improvement of an engine’s power.
As opposed to common beliefs, changing to a fuel that has higher octane ratings is not the only thing that can result to the production of more power by an engine. Fuel that has a high octane rating is important in high compression engines because it assists in impeding the probability of detonation or knocking at settings involving high power.

The other type of AV gas is the AV gas 100LL that contains low lead levels of at least 0.5 grams per liter of fuel. In addition, we have the AV gas 82UL that is a type of unleaded AV gas applicable in engines that have low compression ratios.

In the past, there were various grades of AV gas but today they have been narrowed down to only one type, which is the AV 100.

While adding lead to aviation fuel might be good in enhancing the performance of an engine during combustion, unleaded fuels are recommended for reasons relating to health. Nevertheless, most lead pollutants result from the combustion in the many cars that use lead fuel.
