What is the purpose of fuel system cleaning?

[DelAlivia]

The purpose of fuel system cleaning is to supply the engine with a certain amount of clean, well-atomized gasoline according to its operating conditions, so that it can mix with a certain amount of air to form a combustible mixture. At the same time, the fuel system also needs to store a considerable amount of gasoline to ensure that the vehicle has a considerable driving range. The hazards caused by not cleaning the fuel system include: 1. Carbon deposits and deposits can clog the injector needle valve and valve holes, affecting the performance of the precision components of the injection system, leading to poor fuel injection, poor atomization, and reduced power performance; 2. Carbon deposits and deposits can cause the intake valve to not close tightly, resulting in decreased cylinder pressure or even backfire, leading to unstable engine idle, increased fuel consumption, and worsening exhaust emissions. Carbon deposits on the piston top and cylinder head can easily cause local overheating in the combustion chamber and gasoline pre-ignition, leading to engine knocking and other faults, all of which can shorten the engine's service life.
