Fuel systems are made up of the fuel tank, pump, filter, and injectors or carburetor, and is responsible for delivering fuel to the engine as needed.

Each component must perform flawlessly to achieve expected vehicle performance and reliability.

Over time, an engine’s performance can slowly diminish because of buildup, which clogs vital parts of the fuel systems and causes reduced fuel efficiency and power.

Fuel systems are critical in storing and delivering the fuel your engine needs to run.

Fuel Injectors/Carburetors

The fuel injector is the last stop for fuel in your engine before it goes “boom!” inside the combustion chamber. Carburetors, were the usual method of fuel delivery for most vehicles up until the late 1980s.

Intake Valve

So, The valve opens to allow the air/fuel mixture to be drawn into the combustion chamber. Finally, Deposits on the intake valves can restrict or change the flow of the air/fuel mixture into the combustion chamber. Fuel can stick to deposits on the intake valve and not enter the combustion chamber when needed. Consequently, The right fuel additive can help reverse these effects and restore lost performance.

Combustion Chamber

So, This is where burning of the air/fuel mixture happens. Finally, Deposits in the combustion chamber can affect heat transfer and air/fuel compression. Excess heat can cause premature ignition and knocking.

So, Some vehicles contain knock sensors that are used to determine engine knock or pre- or post-detonation. Also, With these sensors, the computer will detune the engine to eliminate this symptom, which has an adverse effect on performance. Fuel systems deposits will cause knocking, which is why it is so important to keep your fuel systems clean.
