the engine acceleration increases significantly.
The temperature of gasoline, at which all its heavy fractions are
completely boiled away, has a significant impact on the overall life of
the engine. If gasoline contains a lot of high-boiling hydrocarbons and
other compounds, they do not evaporate in the engine intake pipe and
enter the cylinders in liquid form. Some of the liquid gasoline entering
the cylinders evaporates and burns, while the rest flows down the cylinder
walls and washes away the oil. In this case, heavy fractions of gasoline
get into the oil.
Engine knocking or detonation occurs when the fuel is pre-ignited
before the piston reaches its scheduled spark ignition. This means that
a powerful explosion is trying to expand the cylinder chamber, which
is compressed in size, trying to change the direction of movement of
the piston and engine. When detonation occurs, the internal pneumatic
forces can actually be up to 10 times the normal forces acting on a
properly running high performance engine. Knocking is usually caused
by excessive heat, excessive cylinder pressure, incorrect ignition timing,
insufficient fuel octane, or a combination of these factors. From the
previous one, excessive heat is usually to blame. As the engine is modified
to produce more power, additional heat is generated [3].
The increased acidity of the fuel and the presence of water in it in
many cases increase the corrosion of the fuel system. Water and watered
fuel cause corrosion mainly of the steel parts of the fuel system. Corrosion
manifests itself in the form of local darkening, individual spots, rust
and small point lesions of metal surfaces. In this case, brown flakes are
formed in the fuel, consisting of iron hydroxide. These flakes can clog
fuel filters, as well as jam the plunger pairs of fuel pumps. The increased
