AV Gas as a Common Aviation Fuel.
There are several types of fuel that can be used by aircraft depending on which kind of aircraft it is. While Jets use diesel fuels, other aircrafts have engines that run on Mogas or AV gas. In this piece of writing, we will discuss about AV gas, its properties, and advantages.
Aviation gasoline or AV gas is the type of gas used in piston powered airplanes. It is one of the most commonly used aircraft fuel that has been there for a long time. AV gas is mainly used to help in the functioning of 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 regular temperatures, Aviation gasoline is extremely volatile and highly flammable. As a result, it should always be handled with extreme care for safety. The two main types of ratings for AV gas are lean and rich mixture ratings which are the octane ratings that define the various grades of AV gas.
Gasoline fuels are mostly prepared from hydrocarbons the most common being iso-octane. Iso-octanes are hydrocarbons that have outstanding antiknock properties. The fuels that have antiknock properties that bear resemblance to those of iso-octane are mostly rated 100. Heptane is one other hydrocarbon that when mixed with a given amount of iso-octane, it may be used for fuel rating.
Today, additions of lead and other replacements, increase the engine’s power prior to detonation. This means that the addition of lead will improve the performance of the engine. Another factor that helps to increase the power of an engine is the air ratio of the fuel.
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. High octane rated fuels are essential in high compression engines due to fact that they help to delay the probability of knocking or detonation at high power settings.
The next category of AV gas is the AV gas 100LL that has a low lead content of 0.5 gr/ltr. 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.
Even though the addition of lead in aviation results into more power for an engines during combustion, environmentalists recommend that we use unleaded fuels for safety of health. However, lead pollution is mostly caused by the millions of cars that use lead fuel.
