大家对汽油和、乙醇汽油的了解已经不少了，甲醇汽油呢？
　　Everyone knows a lot about gasoline and ethanol gasoline. What about methanol gasoline?
　　食物有保质期，时间久了就会变质，同样甲醇汽油也有保质期。
　　Food has a shelf-life, which will deteriorate over time, as well as methanol and gasoline.
　　汽车现在作为已经普及的交通工具，家家户户都有了，有部分人是经常用车族，也有的人在平时用车较少，汽车经常闲置，可能一停就是几个月。
　　As a popular means of transportation, automobiles now exist in every household. Some people often use automobiles. Others use less cars in peacetime. Cars are often idle. They may stop for several months.
　　发动机就像是人的胃一样，甲醇汽油就是食物，长时间存放的甲醇汽油到底能不能继续使用了呢？
　　Engines are like human stomachs. Methanol gasoline is food. Can methanol gasoline stored for a long time continue to be used?
　　甲醇汽油就是甲醇和添加剂和汽油的混合产物，众所周知甲醇具有亲水性，长时间暴漏在空气中的甲醇会吸水。汽油中的主要物质的分子结构是碳元素和氢元素，汽油长时间裸露在空气中也会发生缓慢的化学反应，和氧气发生反应会产生胶质！
　　Methanol gasoline is a mixture of methanol, additives and gasoline. It is well known that methanol is hydrophilic, and methanol leaking in the air for a long time will absorb water. The molecular structure of the main substances in gasoline is carbon and hydrogen. Gasoline exposed in the air for a long time will also undergo slow chemical reactions, and react with oxygen to produce colloids!

　　当甲醇汽油中水分超过一定量时候，其会发生分层的现象，也就是油水分层！
　　When the moisture content in methanol gasoline exceeds a certain amount, it will occur stratification phenomenon, that is, oil-water stratification!
　　发生变质的甲醇汽油在发动机内燃烧时会发生燃烧不充分的情况，会产生焦黑色的积炭化学物质，这些燃烧产生的物质会使发动机内壁、活塞、气门产生摩擦、损坏和堵塞，长时间进而造成发动机产生故障。
　　When the deteriorated methanol gasoline is burned in the engine, it will cause insufficient combustion, which will produce coke-black COKE-DEPOSITED chemicals, which will cause friction, damage and blockage on the inner wall, piston and valve of the engine, and then cause engine failure for a long time.
　　所以说甲醇汽油也是有保质期的，通过科学的实验和总结，甲醇汽油在密封良好的情况下可以存储一年，在敞口接触空气后可以存储的时间为3-5个月。
　　So methanol gasoline also has a shelf life. Through scientific experiments and summary, methanol gasoline can be stored for one year under the condition of good sealing, and the storage time after exposure to air is 3-5 months.
