The Correct Answer and Explanation is :
The correct answer is : When the air compressor pumps air into the air storage tanks.
The air compressor governor is a key component in a vehicle’s air braking system. It regulates the operation of the air compressor, ensuring that air is pumped into the air storage tanks only when necessary. The governor controls when the air compressor turns on and off, based on the pressure levels within the air tanks.
Explanation:
The air compressor in vehicles, particularly in commercial trucks and buses, is responsible for generating compressed air, which is then stored in air tanks. These air tanks are essential for powering the air brake system, suspension systems, and other air-powered components.
The air compressor governor is a device that regulates the pressure within these storage tanks. It typically has a set range of pressure (known as cut-in and cut-out pressure). The governor allows the compressor to begin pumping air when the air pressure in the tanks drops below the cut-in pressure and stops the compressor once the tanks reach the cut-out pressure, which prevents over-pressurization.
- Cut-in pressure is the lower limit at which the governor allows the compressor to start operating. When the air tank pressure falls below this level (due to air usage by the braking system or other components), the governor triggers the compressor to begin pumping air into the storage tanks.
- Cut-out pressure is the upper pressure limit at which the governor turns the compressor off, ensuring the air tanks don’t become over-pressurized.
The governor does not directly control how fast the air is pumped, the temperature of the air, or the speed of the vehicle. These factors are either controlled by the compressor’s design or other systems within the vehicle. The primary function of the governor is to manage when the air compressor should operate to maintain the proper air pressure in the storage tanks. This ensures the vehicle’s air systems function correctly and safely.
