Which component is NOT part of the EVAP system?

The fuel injector is the correct choice as it is not part of the Evaporative Emissions Control (EVAP) system. The primary purpose of the EVAP system is to prevent the release of fuel vapors from the fuel tank into the atmosphere, thereby controlling emissions from the vehicle.

The other components listed, including the charcoal canister, purge valve, and vent solenoid, are crucial elements of the EVAP system. The charcoal canister absorbs fuel vapors that escape from the fuel tank, while the purge valve regulates the flow of those vapors into the engine during certain conditions, allowing for combustion. The vent solenoid allows the system to release or trap vapor as needed during various engine operations.

The fuel injector, however, plays a different role in the vehicle's operation, being responsible for delivering fuel directly into the combustion chamber, and is not involved in the management of fuel vapors or emissions control that the EVAP system addresses. This distinction is key in understanding the components and functions within an automotive emissions control system.
