Question

What may happen if you don't keep the air alcohol evaporator unit filled with alcohol?

1) The air brakes system may not function properly
2) The air brakes system may overheat
3) The air brakes system may leak
4) The air brakes system may freeze

Answer 1

If the air alcohol evaporator unit is not filled with alcohol in an air brakes system, it can lead to brake malfunction, overheating of the compressor, and the risk of freezing in cold temperatures.

Step-by-step explanation:

If the air alcohol evaporator unit in the air brakes system is not filled with alcohol, several issues may arise:

1. The air brakes system may not function properly: The purpose of the air alcohol evaporator is to remove moisture from the compressed air in the air brakes system. When moisture accumulates in the system, it can cause corrosion and damage to components, leading to brake failure.
2. The air brakes system may overheat: Alcohol in the air alcohol evaporator helps to cool down and lubricate the air compressor. Without alcohol, the compressor can overheat and potentially fail.
3. The air brakes system may freeze: Alcohol is also used as an antifreeze in the air brakes system. Without alcohol, the system may freeze in cold temperatures, resulting in brake failure.
