What component is responsible for distributing fuel to each cylinder?

The fuel distribution valve plays a crucial role in the operation of an aircraft's fuel system by ensuring that fuel is delivered to each cylinder of the engine in the appropriate quantity. This component helps to regulate the flow of fuel, allowing for optimal engine performance and efficiency during various phases of flight. It is designed to manage the distribution of fuel, thereby ensuring that each cylinder receives the needed fuel for combustion, which is vital for maintaining the engine's power output and reliability.

Other components mentioned, such as the fuel strainer, primarily serve to filter the fuel before it reaches the engine, preventing contaminants from entering the fuel system. The fuel shutoff valve is designed to stop the fuel flow, typically used for emergency situations or during engine shutdown. Meanwhile, the fuel/air control unit regulates the mixture of fuel and air entering the engine, but it does not directly handle fuel distribution to the cylinders. Therefore, the fuel distribution valve is the specific component responsible for the essential task of delivering fuel to each cylinder, making it the correct choice.
