In this article, we will delve into the world of gasoline, its properties, and how it affects small engines like those found in lawnmowers.
Understanding Gasoline and Its Properties
Gasoline is a complex mixture of hydrocarbons, which are molecules composed of hydrogen and carbon atoms. The exact composition of gasoline can vary depending on the refinery, the type of crude oil used, and the additives included. Gasoline is a volatile liquid, meaning it evaporates quickly, and it is highly flammable. These properties make gasoline an ideal fuel for internal combustion engines, but they also contribute to its instability over time.
The Effects of Aging on Gasoline
When gasoline sits for an extended period, it undergoes a series of chemical changes that can affect its performance and stability. One of the primary concerns with old gas is the separation of its components. Gasoline is a mixture of light and heavy hydrocarbons, and over time, these components can separate, leading to a change in the fuel’s overall composition. This separation can cause the gas to become less volatile, which can result in a decrease in engine performance.
Another issue with aged gasoline is the formation of gums and varnishes. As gasoline oxidizes, it can form sticky deposits that can clog fuel lines, carburetors, and injectors. These deposits can be difficult to clean and may require professional attention. Additionally, old gasoline can also absorb water from the air, which can lead to phase separation. Phase separation occurs when the water in the gas causes the fuel to separate into distinct layers, making it difficult for the engine to draw the proper mixture of air and fuel.
