Final answer:
The governor is in a position to decrease engine speed when the flyweights are tilted outward and the pilot valve is raised. This is a response to the engine running at or above the desired speed.
Step-by-step explanation:
The question relates to the operation of a mechanical governor in an engine, which is a device used to maintain the desired speed despite load changes. When the flyweights are tilted outward, this typically indicates that the engine is running at or above the desired speed. The outward movement of flyweights due to centrifugal force causes the pilot valve to be raised. When the pilot valve is raised in a hydraulic governor, it redirects fluid flow, which in turn moves the actuator to reduce fuel supply or throttle, thereby decreasing the engine's speed. In the context of a mechanical governor, the raise of the pilot valve could engage mechanisms to similarly reduce the engine speed to maintain the set speed. Therefore, with the governor's flyweights tilted outward and the pilot valve raised, the governor is in a position to decrease engine speed.
