Which system works in conjunction with the throttle to manage fuel flow?

The fuel system is responsible for delivering the right amount of fuel to the engine's combustion chamber and works closely with the throttle to regulate fuel flow based on the engine's demand for power. When the throttle is opened, it allows more air into the engine. In response, the fuel system increases the fuel flow to ensure that the proper air-fuel mixture is maintained for efficient combustion. This dynamic interaction between the throttle and fuel system is crucial for optimizing engine performance, response, and efficiency.

The other systems listed do not directly interact with the throttle for managing fuel flow. The cooling system is focused on regulating engine temperature; the electrical system manages power distribution and battery functionality; and the exhaust system is concerned with expelling gases produced during combustion. None of these systems directly contribute to the regulation of fuel delivery alongside the throttle.
