What does the air compressor governor control?

The temperature of the air system
The amount of air in the tires
When air is pumped into the air tanks
The braking force applied

The correct answer is: When air is pumped into the air tanks

The air compressor governor plays a crucial role in managing the air supply within a vehicle's braking system. It regulates the operation of the air compressor, determining when air should be pumped into the air tanks. The governor senses the pressure in the air tanks and activates the compressor when the pressure drops below a predetermined level. This ensures that there is always enough compressed air available for the operation of the air brakes, enhancing the overall safety and performance of the braking system. In contrast, the other choices do not accurately reflect the function of the compressor governor. The temperature of the air system is influenced by operational conditions but is not directly controlled by the governor. Air pressure in tires is unrelated to the town's air supply for braking; tire pressure management falls under a different system. Lastly, while the braking force is essential for vehicle control, it is achieved through the air pressure supplied to the brake chambers, not specifically regulated by the governor itself. The governor's primary responsibility is about air supply to the tanks, solidifying why that choice is the correct answer.
