Quiz sur les composants du freinage pneumatique des poids lourds

What is the role of the compressor in the pneumatic braking system of heavy vehicles?

• Control the engine temperature

• Filter the engine oil

• Maintain air pressure in the braking system

• Increase vehicle speed

What is the main reservoir in the pneumatic braking system of heavy vehicles?

• A fuel tank for the heavy vehicle's engine

• A compartment for storing passengers' luggage

• The place where compressed air is stored before being distributed to the brakes.

• A space for storing repair tools

What is the role of the air dryer in the pneumatic braking system of heavy-duty vehicles?

• It eliminates moisture from the compressed air to prevent corrosion and freezing in the pneumatic braking system of heavy vehicles.

• It reduces the pressure of the compressed air to decrease the efficiency of the pneumatic braking system of heavy vehicles.

• It increases the moisture of the compressed air to improve the performance of the pneumatic braking system of heavy vehicles.

• It adds foreign particles to the compressed air to increase wear on the components of the pneumatic braking system of heavy vehicles.

What is the control valve in the pneumatic braking system of heavy vehicles?

• Controls the temperature of the brakes

• Provides oil to lubricate the brakes

• Controls the air pressure to activate or deactivate the brakes

• Controls the direction of the vehicle

What is the role of the pressure limiter in the pneumatic braking system of heavy goods vehicles?

• The pressure limiter regulates the oil level in the braking system

• The pressure limiter increases the air pressure in the braking system

• The role of the pressure limiter is to limit the air pressure in the pneumatic braking system of heavy goods vehicles.

• The pressure limiter controls the temperature of the braking system

What is the relay valve in the pneumatic braking system of heavy vehicles?

• A hose that carries air between the brakes

• A device to regulate the temperature of the brakes

• A sensor to measure tire pressure

• A component that controls the air pressure between the tractor and trailer brakes.

What is the role of the secondary air reservoir in the pneumatic braking system of heavy-duty vehicles?

• It controls the temperature of the air in the braking system

• It stores coolant for the brakes

• It stores compressed air to power the brakes in case of a leak or loss of pressure in the main system.

• It regulates the pressure of the truck's tires

What is the purge valve in the pneumatic brake system of heavy-duty vehicles?

• A valve that controls the flow of fuel to the engine

• A device that allows the release of compressed air from the system to purge moisture and contaminants.

• A device that increases the air pressure in the system

• A mechanism that regulates the temperature of the coolant

What is the role of the connecting pipe in the pneumatic braking system of heavy goods vehicles?

• Provide oil to the brakes

• Transmit the pressure from the tractor braking system to the trailers.

• Assist in vehicle steering

• Control the temperature of the brakes

What is the control valve in the pneumatic braking system of heavy vehicles?
