Self-cleaning specialty
The ethanol in vehicle ethanol gasoline is an excellent performance organic solvent with strong dissolving and cleaning characteristics. Those experienced drivers and maintenance personnel often use ethanol to clean carburetors. The carburetors washed by this method are clean and thorough. For the same reason, vehicle ethanol gasoline can also do. However, when cars use Ethanol gasoline in the first time, especially after use 1-2 times, under the ethanol gasoline cleaning function, all kind of impurities such as rust, dirt, colloid etc. deposited on the tank, oil way will soften and dissolve down, then mix in oil. These impurities may cause oil way to be blocked.
Suggestion: when cars use ethanol gasoline in the first time, it is better to clean the main parts of car oil tank and channel, like fuel filter, carburetor to ensure burning system clean.
Water-wet behavior
As Ethanol gasoline additives are mixed with a certain amount of denatured fuel ethanol, ethanol has water-wet behavior which dissolves with water easily. It is not same with gas which can separate from water then water deposits in the tank bottom. So before use ethanol gasoline additives, you’d better check your tank if it has water to make engine abnormal work.
First of all, long maintenance period
Methanol gasoline within the low water content and the normal temperature can maintain stably above six months, no emulsification, no separation. It also can solve the time problems of store, transportation, and sale,
Second, safe, convenient
The steam pressure of methanol is lower than gasoline; the specific gravity is larger than gasoline, compared with steam, not easy to volatilize and come-up and fire risk smaller. Methanol has good conductivity which can reduce the danger of electrostatic generation and accident fire hazard, therefore, Methanol gasoline store, transportation, mix and use is safer than national standard gasoline.
The car structure, gas station, oil storage etc. equipments needn’t do big change.
Third, good generality
Methanol gasoline can use alone, and can mix with national gas, Ethanol gasoline in any property as well.
Last, green and clean
Methanol gasoline is green clean fuel committed by state, creating lower emissions from automobiles, complying with the national standard requirements.
NDRC put forward that the ethanol gasoline application in our country will extend 9 provinces this year. According to the requirements that every liter of gasoline must mix 10 liters, in 2005, we will consume 1,200,000 tons ethanol gasoline fuel.
Although now the ethanol gasoline companies still depend on financial revenue to complement the loss, but along with crude oil rises in price more, gas price will much higher than Ethanol gasoline additives and then the listed companies will march to profit increase period.
The mixed methanol ranges from 5%-30% generally, taking 15% as many which is called as M15 methanol gasoline in good resistance-blast performance. RON increases with methanol amount, but MON isn’t affected. Besides, the burning effluent toxicity is lower than ordinary leaded gasoline, for another, effluent CO is also relative low, with good burning clean function. However the common methanol gasoline corrodes petrol engine and swells rubber material stronger than others, as well as easy to layer. And low-temperature runnability and cold-start performance are inferior to pure oil, which can be regarded as the petrol succedaneum. In addition, many countries made a lot of tests, and many of them make Methanol gasoline additives into industrialized application.
