大家對汽油和、乙醇汽油的了解已經(jīng)不少了，甲醇汽油呢？
　　Everyone knows a lot about gasoline and ethanol gasoline. What about methanol gasoline?
　　食物有保質(zhì)期，時(shí)間久了就會(huì )變質(zhì)，同樣甲醇汽油也有保質(zhì)期。
　　Food has a shelf-life, which will deteriorate over time, as well as methanol and gasoline.
　　汽車(chē)現在作為已經(jīng)普及的交通工具，家家戶(hù)戶(hù)都有了，有部分人是經(jīng)常用車(chē)族，也有的人在平時(shí)用車(chē)較少，汽車(chē)經(jīng)常閑置，可能一停就是幾個(gè)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.
　　發(fā)動(dòng)機就像是人的胃一樣，甲醇汽油就是食物，長(cháng)時(shí)間存放的甲醇汽油到底能不能繼續使用了呢？
　　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劑和汽油的混合產(chǎn)物，眾所周知甲醇具有親水性，長(cháng)時(shí)間暴漏在空氣中的甲醇會(huì )吸水。汽油中的主要物質(zhì)的分子結構是碳元素和氫元素，汽油長(cháng)時(shí)間裸露在空氣中也會(huì )發(fā)生緩慢的化學(xué)反應，和氧氣發(fā)生反應會(huì )產(chǎn)生膠質(zhì)！
　　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!

　　當甲醇汽油中水分超過(guò)一定量時(shí)候，其會(huì )發(fā)生分層的現象，也就是油水分層！
　　When the moisture content in methanol gasoline exceeds a certain amount, it will occur stratification phenomenon, that is, oil-water stratification!
　　發(fā)生變質(zhì)的甲醇汽油在發(fā)動(dòng)機內燃燒時(shí)會(huì )發(fā)生燃燒不充分的情況，會(huì )產(chǎn)生焦黑色的積炭化學(xué)物質(zhì)，這些燃燒產(chǎn)生的物質(zhì)會(huì )使發(fā)動(dòng)機內壁、活塞、氣門(mén)產(chǎn)生摩擦、損壞和堵塞，長(cháng)時(shí)間進(jìn)而造成發(fā)動(dòng)機產(chǎn)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.
　　所以說(shuō)甲醇汽油也是有保質(zhì)期的，通過(guò)科學(xué)的實(shí)驗和總結，甲醇汽油在密封良好的情況下可以存儲一年，在敞口接觸空氣后可以存儲的時(shí)間為3-5個(gè)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.
