为什么汽油里含酒精呢？

[Squall]

我在Sunoco加油的时候看到油泵上写着含10%酒精。这样的油不是消耗得很快嘛？

其他油站这么干吗？

政府规定

这样减少emission，并可以增加加拿大玉米的销售量（玉米－>酒精）

Sustainable energy source. I don't think it affects the performance of your car or increases fuel comsuption.

u're so wrong

chemistry tells us, gasoline has much higher potential energy than alcohol

每个油站都这么加酒精的吗？我在Sunoco才看到的。ESSO都没写。

这是政府规定的

现在PC,Esso，Shell等还没加（Ethonal),以后也会加的。
Ethonal溶解性很强，对旧车不是太好。
理论上热值底，但实用10%没有什么区别。
超过10%，比如巴西，车要去改造。

Here is some information from the Canadian Government.

"Using a 10 percent ethanol blend (E-10) does not significantly affect a vehicle's fuel economy or horsepower. Although 10 percent ethanol-blended gasoline contains only 97 percent of the energy of pure gasoline, this is partially compensated by the improved combustion efficiency of gasoline that the added ethanol provides. Overall, use of E-10 increases fuel consumption by an average of 2 percent compared with pure gasoline. However, this is only a slight difference when compared with other factors that have a larger impact on fuel economy. For example, driving at 120 km/h rather than 100 km/h increases fuel consumption by an average of 20 percent."

I say, it is negligible. YOur driving habits have more effect.

they're gonna change it to 15%

read that in the papers a while back

think of it this way - gasoline soaked paper will burn the paper if u ignite the gasoline

but alchohol soaked paper will not burn when u ignite it

that's why u can allow alcohol to fire on ur hand

but not gas

请问，hybrid的电是哪来的？

charge 或者 发动机发电

减速的时候也发电
