Which governor component acts as the brain of the governor?

The electronic control unit (ECU) serves as the "brain" of the governor because it processes information and makes real-time adjustments to optimize engine performance and stability. The ECU is responsible for receiving data from various sensors, such as throttle position and engine speed, and using algorithms to determine the appropriate adjustments needed to maintain the desired engine parameters.

The ECU executes commands to other components, such as the governor actuator, based on the processed information. This ability to quickly analyze and respond to changing conditions is crucial for maintaining optimal power output and efficiency in engines, particularly in applications such as electric power production, where precise control is essential for reliability and performance.

The other components, while important to the function of the governor, do not independently perform the role of processing information and controlling the system. The mechanical linkage connects the physical components but does not have processing capability. The governor actuator carries out commands from the ECU but relies entirely on the ECU's guidance for its operations. The throttle position sensor provides important data but does not engage in decision-making or control functions. Thus, the electronic control unit is central to ensuring that the governor operates effectively and efficiently.
