5. Operation

The fuel injector is a critical component of the engine's fuel delivery system. It is electronically controlled to spray a precise amount of fuel into the engine's combustion chamber at the correct time. Once installed, the injector operates automatically as part of the engine management system. No user intervention is required for its operation.
