燃料是車輛最重要的能量來源
不知道酒精汽油的缺點的人現在真的一堆,
有些東西,上流廠商都會故意不說,要有人逼得他們說才會說, 那時通常都是車出事時才會發生.
E3 = ETHANOL 3%
國外很多車都在加 E10 , 都出現問題了, 不說明不行:
Ethanol absorbs water from the atmosphere
Gasoline with 10% ethanol can absorb 50 times as much water as gasoline without alcohol.
E10 的吸水量是普通汽油的50倍, E3自己算...
Phase Separation
The ethanol will continue to absorb water from the atmosphere only up to a point. With 10% ethanol, when the water reaches 0.5% (3.8 teaspoons per gallon), phase separation will occur. Phase separation is the term used to describe the formation of distinct layers, with a thicker layer of gasoline mixed with a little ethanol on top, and a thinner layer of water and more ethanol on the bottom. The lower layer can have as much as 75% ethanol in it. This process is unavoidable, and it can also be triggered by a drop in temperature.
汽油/酒精分離, 燃料比例完全走掉.
Phase Separation Related Problems
Shelf Life: A gasoline-ethanol mix will absorb water until it reaches a concentration that triggers the phase separation. E-10 gasoline has a 90 day shelf life when kept in a sealed tank. At about 100 days, even in a sealed tank, it may have absorbed enough water to begin to separate. With a vented gas tank, there will be significant amounts of water in the tank in 30 to 45 days. With 10% ethanol blends, it is suggested that you replace the fuel in the tank on a 2 to 4 week cycle.
加了只能放 2-4個禮拜,不然會分離.
Octane: When gasoline and ethanol are mixed, the octane rating achieved is due partly to the ethanol. When phase separation occurs, the octane rating of the fuel can drop by as much as 3 points, and there is an increased risk of detonation, “knocking” or “pinging”.
下跌3點的OCTANE 引擎暴震機率偏高.
Rough Running (or stalling): Because the water-ethanol mix is at the bottom of the tank, the fuel pump may pick up a slug of this mixture, and the engine will run very poorly or perhaps die.
用到分離的汽油會讓引擎跑起來很沒力,也可能毀了引擎.
Corrosion and Rust: Water in contact with the bottom of the fuel tank and inside the fuel lines will cause rust, and that in turn will tend to clog fuel filters and lines.
生鏽,水分%提升的後遺症.
重點:
原廠目前有哪家建議用種汽油??
用了可能就沒保固了....

這些都是真的在國外發生過的案例 , 不負責告知消費者的是誰請自己去想...
