What are the advantages and disadvantages of methanol engines?

The following introduces the advantages and disadvantages of methanol engines: Advantages of methanol fuel: The modifications required for the original engine are relatively minor. While maintaining the original engine's power performance, both its economy and emissions can be significantly improved; it causes less environmental pollution to the atmosphere and is considered a clean alternative fuel for automotive engines; methanol fuel is a liquid fuel, allowing the use of existing petroleum fuel storage and transportation systems, thus requiring minimal infrastructure investment. Disadvantages of methanol fuel: Methanol fuel itself is toxic—ingesting as little as 5 to 10 milliliters can cause blindness, and large amounts can be fatal; methanol flames are colorless, making them difficult to detect; engines using methanol as fuel emit harmful gases such as unburned alcohols and formaldehyde (HCHO) in their exhaust.
Having driven for over a decade, what attracts me most about methanol engines is their rapid acceleration, powerful performance, and clean, eco-friendly combustion—unlike gasoline cars with their black exhaust fumes. However, the downsides are quite noticeable: cold starts in winter are a nightmare, taking forever to ignite, and methanol refueling stations are scarce, requiring careful planning for long trips. Additionally, methanol corrodes engine rubber components quickly, so I frequently have to replace seals. It’s decent for daily use, but regular maintenance is crucial to prevent carbon buildup. In the long run, if more refueling stations become available, it’s definitely a great choice—cost-effective and low-carbon. Remember, checking the fuel system before seasonal changes is essential.
As an ordinary person who cares about sustainable development, I appreciate the environmental benefits of methanol engines. They use renewable resources, produce fewer emissions, and help keep the air cleaner. However, there are also significant drawbacks: the low energy density of the fuel means more refueling is needed for the same distance, making it less economical; cold starts can be difficult, which is frustrating when you're in a hurry in the morning; and the lack of infrastructure, with few fueling stations available, limits daily convenience. I suggest cities trial the installation of charging stations. Overall, methanol engines represent a future direction, but widespread adoption will require government support.
