Which component is responsible for controlling the amount of fuel delivered to the cylinders during operation?

• A. Throttle body
• B. Fuel injector
• C. Governor
• D. Timing belt

Answer: (C)

The governor is the device that controls how much fuel reaches the cylinders while the engine is running. It continuously senses engine speed and adjusts the fuel metering mechanism (such as the fuel pump rack or metering valve) to increase or decrease fuel delivery as needed to keep the RPM within the desired range. If the engine starts to overspeed, the governor reduces fuel; if speed drops, it allows more fuel to flow to restore speed. The throttle body influences air intake, which affects the mixture but doesn’t by itself meter fuel. The fuel injector actually delivers fuel, but its amount per cycle is governed by the engine’s fuel control system, which the governor helps regulate. The timing belt simply synchronizes valve timing and doesn’t control fuel delivery.
