<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">笔者的一位朋友几乎每周都要从上海开车去北京送货，每次出发之前都要干一件事，那就是将一个备用油桶灌满汽油。最初，我很诧异外地汽油比上海要便宜，为何要在上海灌油桶？</span></p>
<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">答曰：“便宜有什么用，山东用的是乙醇汽油，动力差的不是一点半点，就指望用这桶油熬过山东，到了天津就好了！”</span></p>

<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;"><strong>一、乙醇汽油动力其实不差</strong></span></p>
<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">目前，乙醇汽油在国内已经是相当普及，黑龙江、吉林、辽宁、河南、安徽五省全境，江苏北部、山东西南部、湖北大部以及河北大部均是乙醇汽油的统治区，网络上将其戏称为“乙统区”。</span></p>
<p style="text-align:center"><img src="http://www.autoju.com/wp-content/uploads/2015/11/97641447810441.jpg" style="margin-top: 10px; width: 550px; height: 340px;"/></p>
<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">这些地区的车主几乎没人对乙醇汽油存在好感，均认定乙醇汽油动力差，油耗高。尽管乙醇汽油价格相比普通汽油略微便宜，但是以每公里的行驶成本来看，反而比普通汽油更高。究其原因，是乙醇热值比汽油小——大约只有普通汽油热值的0.6～0.7左右，但就此坐实“乙醇汽油动力差”的结论，似乎还为时尚早。</span></p>
<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">大众之前曾经在巴西发布过一款既可以加注普通汽油，又可以使用乙醇作为燃料的Kombi双燃料面包车，根据大众官方的说法，这款车在使用乙醇燃料时，引擎输出会比使用普通汽油高2马力——这似乎和“乙醇热值比汽油小”的说法正好矛盾。</span></p>
<p style="text-align:center"><img src="http://www.autoju.com/wp-content/uploads/2015/11/14591447810441.jpg" style="margin-top: 10px; width: 550px; height: 367px;"/></p>
<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">而瑞典超级跑车制造商Koenigsegg也在其产品介绍中表示，其旗下的CCXR跑车在使用普通汽油时最大输出806马力；而使用E85生物乙醇汽油之后，最大输出跃升至1018马力——如此也佐证了乙醇汽油的动力性优于普通汽油。</span></p>
<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">那么，这究竟是怎么一回事？说白了，所有的“乙统区”的中国车主都犯了一个概念混淆的错误——将燃料的动力表现和热值混为一谈了。例如，1公斤TNT炸药爆炸能释放出420万焦耳的能量，1公斤标准煤的热值则高达2926万焦耳，从热值上看，TNT不及煤炭的零头，但是就爆炸威力而言，煤是永远都无法和TNT相提并论的。鄙视乙醇汽油的车主们都忽视了一个物理参数，那就是能量释放的速度——这就是TNT之所以能成为炸药的根本原因。</span></p>
<p style="text-align:center"><img src="http://www.autoju.com/wp-content/uploads/2015/11/47691447810441.jpg" style="margin-top: 10px; width: 550px; height: 340px;"/></p>

<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">换句话说，我们可以将乙醇汽油看作是一名短跑选手，瞬间爆发力是其优势——热值小，但是燃烧速度更快，单位时间内释放出的能量更多；而汽油这可以被视为是马拉松选手，热值高，能量释放速度慢，但可以跑得更远。</span></p>
<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;"><strong>二、国产乙醇汽油问题在哪？</strong></span></p>
<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">前面已经说过，乙醇汽油蒸发潜热较大，约是普通汽油的两倍多。这就造成雾化的乙醇汽油进入气缸形成蒸发之后，所吸收的热量要比汽油大。这种物理特性导致使用乙醇汽油的车在严寒气候下启动相对困难、热车时间过长等问题，然而问题在于，乙醇汽油恰恰是在北方省份地区重点推广普及的。</span></p>
<p style="text-align:center"><img src="http://www.autoju.com/wp-content/uploads/2015/11/22371447810442.jpg" style="margin-top: 10px; width: 550px; height: 339px;"/></p>
<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">相对而言，涡轮增压车型由于进气温度被涡轮加热，因此使用乙醇汽油时工况会更好一些。此外，乙醇汽油的沸点只有78.C%，在引擎正常工作温度下，很容易因为受热气化产生气阻，导致在炎热气候条件下较易出现燃料供给降低甚至中断的现象。换句话说，乙醇汽油比较“娇气”，热不得也冷不得。</span></p>
<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">其次，乙醇在燃烧后不仅仅只产出水和二氧化碳，还会产生乙酸——也就是我们常说的醋酸，对汽车金属特别是铜有腐蚀作用，尤其是乙醇汽油的含醇量超过15%时，这种腐蚀作用将更明显。由于乙醇汽油保质期短的特点决定了乙醇汽油不能大规模生产和储运，只能由各地方“现兑现用”，所以笔者不敢肯定，中国的乙醇汽油中乙醇掺比是否严格按照10%添加，或者某些加油站是否会擅自兑入更多乙醇……话不多说，怀疑而已。</span></p>
<p style="text-align:center"><img src="http://www.autoju.com/wp-content/uploads/2015/11/86551447810442.jpg" style="margin-top: 10px; width: 550px; height: 340px;"/></p>

<p style="margin-top: 0px; margin-bottom: 15px; padding: 0px; word-break: break-all; word-wrap: break-word; color: rgb(51, 51, 51); font-family: 宋体, Arial, Helvetica, sans-serif; white-space: normal; line-height: 1.75em; text-align: left;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">不过话说回来，一个月用不掉一箱汽油的情况依然算是“低概率”事件，对那些动辄两三天加一次油的车主而言，问题或许更严重：乙醇作为一种优良的溶剂，会对供油管路进行“清洗”——尤其对于金属油箱而言清洗效果更甚，而这也是官方宣传乙醇汽油的优点之一。</span></p>
<p style="text-align:center"><img src="http://www.autoju.com/wp-content/uploads/2015/11/36351447810442.jpg" style="margin-top: 10px; width: 550px; height: 339px;"/></p>
