If your vehicle has an alcohol evaporator, it is there to

• A. improve braking power
• B. reduce noise
• C. reduce the risk of ice in valves and other parts in cold weather
• D. increase fuel economy

Answer: (C)

An alcohol evaporator is for preventing ice buildup in cold weather. It introduces alcohol into the intake path, which evaporates and helps absorb moisture while lowering the freezing point of water in the fuel/air system. This reduces the chance that ice forms on valves and other parts, keeping airflow and fuel delivery from being blocked in cold conditions. It isn’t about braking power, reducing noise, or improving fuel economy.
