What is the purpose of fuel system cleaning?

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.
Fuel system cleaning really breathes new life into your car! After driving my own car for five or six years, I noticed it kept hesitating during acceleration and fuel consumption skyrocketed. After getting it cleaned, I instantly felt the power return, and the throttle response became much sharper. The cleaning mainly removes carbon deposits and impurities from the engine—these gunk up the fuel injectors and fuel rails like grease, worsening gasoline atomization and reducing combustion efficiency. If left uncleaned, the engine shakes noticeably and may even exceed emission standards. I do this maintenance every 20,000 kilometers, and now my car runs quietly and smoothly, saving me a lot on fuel costs even in city driving—probably hundreds of dollars a year. More importantly, regular cleaning is far cheaper than fixing major issues—replacing clogged fuel injectors can cost thousands, while cleaning only takes a few hundred bucks. It's a super worthwhile investment!
I've been through quite a few vehicle maintenance procedures, and the key to fuel system cleaning lies in keeping the engine internals clean. When gasoline quality is poor, residues form stubborn carbon deposits that accumulate in fuel lines and injectors, hindering proper combustion. The cleaning process dissolves these deposits, allowing for more uniform fuel atomization and complete combustion, thereby improving engine power output. Vehicles that haven't undergone cleaning experience power loss and severe idle vibration. Long-term neglect may damage components, such as shortening oxygen sensor lifespan. I recommend drivers check every 30,000 kilometers, especially after using substandard fuel - prompt cleaning can prevent minor issues from becoming major repairs. It's also beneficial for emission systems, reducing exhaust pollution. We often observe significant data improvements at testing facilities.
