What does "injector cleaning" typically involve?

Injector cleaning typically involves the process of removing carbon deposits and other blockages that may accumulate within the fuel injectors. Over time, fuel injectors can become fouled due to combustion residues, leftover fuel, and other contaminants that can impair their performance. Effective cleaning processes may involve ultrasonic cleaning or the use of specialized cleaning solvents that help dissolve these deposits, ensuring that the injectors can deliver fuel properly and maintain optimal engine performance.

This maintenance step is crucial because clogged or dirty injectors can lead to poor fuel atomization, reduced engine efficiency, and increased emissions. In contrast, replacing the entire injector system or flushing the fuel tank addresses different issues that may not directly resolve the performance problems caused by dirty injectors. Testing injector pulse width is a diagnostic procedure that assesses the correct functioning of the injectors but does not directly involve cleaning. Therefore, the cleaning process is specifically focused on removing deposits and blocking materials to restore the injectors to their proper working condition.
