The 3098693 Speed Control Unit (Governor) is a high-precision electronic controller designed specifically for heavy-duty diesel engines. It is an advanced version within the "Normally Closed" (N/C) series, engineered to handle engines with higher power outputs and more complex fuel systems. It is primarily used to maintain a constant engine speed by controlling the fuel actuator based on real-time feedback from the magnetic speed sensor.
