How to Clean Carbon Deposits in Fuel Injectors?

[DeHope]

For fuel injectors with carbon deposits, fuel injector cleaner can be used for cleaning. Below is relevant information about fuel injectors: 1. Definition of fuel injectors: A fuel injector is essentially a normally closed valve (meaning the valve remains closed when there is no control signal input), with its opening and closing controlled by the up-and-down movement of a valve needle. 2. Main causes of fuel injector sticking: Dirty diesel fuel, excessively high engine temperature leading to poor injector cooling, worn-out fuel outlet valve, low fuel injection pressure, overly tight fit between the injector and its mounting hole on the cylinder head, insufficient clearance between the needle valve body and the cylinder head mounting hole, or excessive depth in the machining of the cylinder head injector mounting hole, among others.
