Got it! Here's a clear answer:
Problems of using Methanol in an Engine:
-
Corrosion:
Methanol is highly corrosive. It can damage metal parts, rubber seals, and plastics inside the fuel system and engine if materials aren't methanol-resistant. -
Lower Energy Content:
Methanol has less energy per liter compared to petrol or diesel (about half).
➔ This means vehicles need more fuel to travel the same distance. -
Cold Start Issues:
Methanol doesn't vaporize easily at low temperatures.
➔ Engines can have trouble starting and running smoothly in cold weather. -
Toxicity:
Methanol is toxic if inhaled, swallowed, or absorbed through the skin.
➔ Special care is needed in handling and storage. -
High Latent Heat of Vaporization:
Methanol absorbs a lot of heat when it evaporates.
➔ This can cause the intake air to cool too much, affecting combustion. -
Compatibility Issues:
Regular engines need modifications to handle methanol properly.
➔ Without changes, problems like poor lubrication and material degradation can occur. -
Storage and Handling Challenges:
Methanol is hygroscopic — it absorbs water from the air.
➔ Water contamination can cause corrosion and performance issues.
