关于E10的一些认识，请大家指正。

ANDERXON

刚到悉尼，因为周边优惠券指定的COLES EXPRESS油站没有不含ETHANOL的，所以网上搜集了一下资料。

特向大家求教。

据资料显示，基本上所有新车型都支持E10，除了90年以前的老车型。具体车型可以参考以下网站：
http://www.fcai.com.au/environme ... hanol-blend-petrol-

但在实际操作中还有以下问题：
1、高于15%的ETHANOL具有高度腐蚀性，对油箱和塑料件不利，故建议10%以下。

2、乙醇具有高效的清洁性，容易清洗出油路的污垢，以致堵塞发动机。车厂建议每3-4万公里对油路彻底清洗一次。

3、E10具有不稳定性，长期不用的车需添加稳定剂，以免油液分离。

4、E10的性能不一样，可能要调教怠速和点火时间，而且油耗会高5%。

5、还有容易产生负压，所以加油不能太满。

6、由于乙醇容易吸水，所以油箱不能太低，水分太多会腐蚀发动机。另外，E10对塑料件有一定腐蚀作用，尤其是油泵中的橡皮膜等。

除了以上，大家有否遇到实际的问题，请大家多指教。

E10有这么多问题呀

没这么严重吧，乙醇汽油也算比较成熟了，在巴西100%都是乙醇汽油。

ANDERXON

LS说得对，新车型基本不用管，特别是油盖上面写明支持的。

但有些车厂要到04年甚至07后的车型才支持E10。

车厂建议注意油滤更换和油路清洗。

巴西100%用ETHANOL 添加油，基本都是E85。

有车厂新出号称支持100%ETHANOL的。

“据资料显示，基本上所有新车型都支持E10，除了90年以前的老车型。”
- - 以上说法很不靠谱。据知，只是近几年的车才开始支持E10。拿我用的车来讲吧，2002年的丰田车还不支持E10。这个需要你认真查看汽车的使用说明书的。找不到说明书的话，你就看汽车加油口的盖盖里面有没有字儿说可以加E10。如没有特别标明可以使用E10，那就不应使用。不应使用不意味着你加了E10，车开不走，只是用久了E10会对发动机寿命有影响。现在普通无铅汽油很难找到了，为了省油钱，好些人，包括我在内，都不管不顾了，直接就加E10了。车跑不动了再说吧，没准儿2012了呢，是吧？

我想加E10,都找不到啊，只能偶尔碰上个别加油站有E10加

我们不在一省呀。不清楚你那边情况。
NSW introduced the compulsory use of ethanol-blended fuel in all vehicles.
以下内容来自政府网站。出处：http://www.biofuels.nsw.gov.au/biofuels_faq/e10_fuel_economy 其中提到E10会比普通无铅汽油耗油3%。当时体会不只3%，而且车用E10比较没劲，不过现在也不去想它了，没选的了。

E10 Fuel Economy
Ethanol contains less heat energy per litre than petrol, therefore E10 will theoretically increase fuel consumption by just over 3%. However, ethanol has a higher octane rating (129RON) than petrol so the addition of 10% ethanol to regular unleaded petrol (ULP) raises the Research Octane Number (RON) from 91 to about 94. This improved anti-knock characteristic can allow an engine to operate with greater efficiency. The ability of an engine to use the extra octane efficiently depends on the design and calibration of its engine management system.  Ethanol also cleans fuel systems and burns more completely, reducing the build-up of carbon deposits and providing long-term benefits.

A trial undertaken in 1998 for the Federal Government in a range of Australian vehicles showed that the use of E10 in vehicles designed for ULP increases fuel consumption by an average of 2.8%, however there was variation between individual vehicle models.

If your vehicle is in good condition you should not experience much more than the theoretical 3% increase in fuel consumption.  If you try E10 and experience an unusually high impact on fuel consumption, there are a few possible causes and things you can do about them:

    Was there water in your fuel tank from earlier contaminated petrol?  If so, the E10 will take the water into solution and your car may run rough until the first tank of E10 is used up.
    Is your fuel filter clogged?  Ethanol is a powerful cleaning agent and may loosen residues in your fuel system.  Try changing the fuel filter after the first couple of tanks of E10.
    Is your ignition system in good condition?  A slightly misfiring spark plug may be exacerbated by E10 leading to a severe misfire and increase in fuel consumption.  Have your vehicle serviced if it has not been done recently.
    Is your engine management system and fuel injection system in good condition?  Most modern vehicles are designed to adjust for variations in fuel composition and should have no trouble adjusting to E10, however a malfunctioning oxygen sensor or other component may mean that your vehicle is not adjusting to the optimum settings for the fuel in your tank.  Have your vehicle serviced if it has not been done recently.

There are many other factors that influence fuel consumption:

Petrol

    Variations between petrol brands/batches – up to 5% difference
    Lower energy content of winter fuel – 5%

Driving Conditions

    Traffic density – add 15% in heavy traffic
    Road conditions – hills, corners, loose surfaces, and wet roads all increase fuel consumption significantly
    Ambient temperature – up to 10% increase in cold weather
    Head winds – 5% increase into a 30 kph headwind

Driving Habits

    Speed – add 10% or more if you speed up from 100 kph to 110 kph
    Aggressive acceleration – up to 20% increase
    Air conditioner use at low speed – add 10-20%
    Windows open at high speed

Vehicle Maintenance

    Tuning and engine maintenance. Clogged air filter 10%. Faulty oxygen sensor 40%.
    Tire pressure – 5% increase if your tires are under-inflated
    Wheel alignment – up to 10%

Vehicle Load

    Unnecessary weight in the vehicle – 45kg can mean a 2% increase
    Roof racks – add 5-10% empty, up to 30% loaded up
    Towing

These factors affect fuel consumption much more significantly than the slightly lower energy content of E10.



The final cost outcome depends on the relative prices of the two fuels. Say you drive an average car and experience a 2.8% increase in fuel consumption on E10.  With current petrol prices (22 Jul 09) at approximately $1.10 per litre for ULP and $1.07 per litre for E10, ULP is 2.8% more expensive than E10.  Actual fuel costs for ULP and E10 are therefore about equal for the average car.



E10 has the additional benefits of:

    reducing greenhouse emissions by 3%,
    reducing cancer-causing particulate emissions by 33%,
    reducing petrol imports by 7%,
    creating regional development and jobs in regional communities, and
    creating new opportunities for farmers and foresters .

As Australia’s oil stocks continue to decline and oil prices inevitably increase in the future, biofuels will provide a cheaper local alternative to imported petroleum.

我们这里都没有人加E10,以前挺多的，可是没人加。估计就撤了。我曾今用过几天的E10，还是相信91了。

政府也在下很大的棋， E10便宜啊， 却关掉91， 如果可行没人抱怨就在全国推广。  毕竟E10成本低，如果抬高价格到91的水平。 就是有大钱赚了。

syd91是比较少了，比e10贵2c。上班路上有一家还有91，上周去加油的时候店里人说2周后也要改e10, 说是政府要求的（据说规定7月起91要全部替换成e10?)。准备以后就加95了

所以我说是变相收钱啊。  好在QLD没人喜欢E10，  E10加的是10%乙醇， 那么价格应该比纯汽油便宜10%， 现在汽油价格是1块3的话，10%应该是1.3C 。 却charge你2C。 已经是在抢你钱了。  然后再取消91号后，把E10的价格水平拉到91的高度。

同时95 98 还需要再涨价， 这样大量的人就会觉得E10好， 去多加E10。  结果为成本最低的E10创造了最高的利润

以前SHELL卖E10的，现在都没看到了

ANDERXON

E10也有它的优点，如E10含氧量高，所以二氧化碳排放低些，且能够清除发动机里面和火花塞的积炭，机油能够用更长时间等等。

不过车厂的态度很模糊，例如本田，除了声明86年以前的发动机型不支持E10，2004年以后的支持E10，中间的就没有说明了。

实际上，那些未标明的发动机可以用E10，但出问题之后你想找他们负责保修就难了，好在这些车型都过了保修。

现在的对策唯有混搭，一箱E10一箱95，怕连续用E10会引致油路堵塞。

挑灯亮剑

sydney的确越来越少纯91了，我常去的两家caltex都先后取消了纯91。现在我周围15公里内，还有三家shell和一家caltex有纯91。但有时单为加91来回20来公里加油不划算。所以现在用油比较乱，91，E10，95都有加。

如果有的选肯定会选91，而不是E10，因为虽然加油时便宜，但车没劲儿，耗油量也大了点，比较下来E10的优势大概也只是在于对环境污染少一点。

混着用对汽车并不是好事。
