Does the Fuel Injector Need Cleaning?

Does the fuel injector need cleaning? The following is a related introduction about the fuel injector: 1. Definition of the fuel injector: The fuel injector itself is a normally closed valve (a normally closed valve means that when there is no input control signal, the valve remains closed), and the opening and closing of the valve are controlled by the up and down movement of a valve needle. 2. The main reasons for fuel injector sticking: unclean diesel fuel, excessively high engine temperature leading to poor injector cooling, worn-out fuel outlet valve, excessively low fuel injection pressure, excessively tight fit between the injector installation hole on the cylinder head and the injector, excessively small clearance between the needle valve body and the installation hole on the cylinder head, excessively deep machining of the injector installation hole on the cylinder head, etc.
As a seasoned auto repair shop owner, I must say fuel injector cleaning is no scam. The injector controls fuel delivery into the engine like a precision nozzle. Over time, impurities or carbon deposits from gasoline can clog it, causing uneven spray, engine misfires, and skyrocketing fuel consumption. Neglecting cleaning may eventually lead to serious engine damage - far costlier to fix. I've seen many car owners regret skipping the $100 cleaning service when facing thousand-dollar engine repairs later. As rule of thumb, inspect and clean injectors every 20,000 km using professional cleaning solutions through the intake system, or remove them for thorough cleaning. Using quality gasoline and avoiding prolonged idling helps reduce cleaning frequency and extends injector lifespan - saving you money and headaches down the road.
