<p style="box-sizing: border-box; color: rgb(68, 68, 68); font-family: helvetica, Arial, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, simsun; font-size: 18px; white-space: normal; background-color: rgb(255, 255, 255); text-align: justify; line-height: 2em; text-indent: 0em;"><span style="font-size: 16px;">DOT3，一般为醇醚型。醇醚型的化学成份为低聚乙二醇或丙二醇。低聚乙二醇或丙二醇具有较强的亲水性，所以在使用或贮存的过程中其含水量会逐渐增高。</span></p>
<p style="box-sizing: border-box; color: rgb(68, 68, 68); font-family: helvetica, Arial, &quot;Hiragino Sans GB&quot;, &quot;Microsoft YaHei&quot;, simsun; font-size: 18px; white-space: normal; background-color: rgb(255, 255, 255); text-align: justify; line-height: 2em; text-indent: 0em;"><span style="font-size: 16px;">DOT4，一般为酯型。酯型是在醇醚型的基础上添加大量的硼酸酯。硼酸酯的沸点比低聚乙二醇或丙二醇更高，所以其制动性能更好，还具有较强的抗湿能力，能减缓了由于吸水而导致的沸点下降。酯型性能比醇醚型更好，但价格也更高。</span></p>

<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &#39;Hiragino Sans GB&#39;, &#39;Microsoft YaHei&#39;, Arial, sans-serif; white-space: normal; text-align: left; line-height: 1.75em; box-sizing: border-box !important; word-wrap: break-word !important; background-color: rgb(255, 255, 255);"><span style="margin: 0px; padding: 0px; max-width: 100%; color: rgb(89, 89, 89); font-size: 14px; font-family: 微软雅黑, &#39;Microsoft YaHei&#39;; box-sizing: border-box !important; word-wrap: break-word !important;">所以，刹车油一定是耐高温、高沸点的产品。例如一些性能优秀的刹车油，干沸点都在250℃以上，湿沸点也在150℃以上。为了更全面衡量刹车油的性能，不同的标号还规定了“干沸点”和“湿沸点”两种参数。</span></p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &#39;Hiragino Sans GB&#39;, &#39;Microsoft YaHei&#39;, Arial, sans-serif; white-space: normal; text-align: left; line-height: 1.75em; box-sizing: border-box !important; word-wrap: break-word !important; background-color: rgb(255, 255, 255);"><span style="margin: 0px; padding: 0px; max-width: 100%; color: rgb(89, 89, 89); font-size: 14px; font-family: 微软雅黑, &#39;Microsoft YaHei&#39;; box-sizing: border-box !important; word-wrap: break-word !important;">其中的“干”和“湿”代表的是刹车油中水分的含量。刹车油是一种醇类制造的合成油，具有很强的吸水性。而汽车里的刹车油又不可能完全隔绝空气，空气中的水分会慢慢被刹车油吸收，这样掺杂着水分的刹车油，沸点就会被拉低。</span></p>

<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &#39;Hiragino Sans GB&#39;, &#39;Microsoft YaHei&#39;, Arial, sans-serif; white-space: normal; text-align: left; line-height: 1.75em; box-sizing: border-box !important; word-wrap: break-word !important; background-color: rgb(255, 255, 255);"><span style="margin: 0px; padding: 0px; max-width: 100%; color: rgb(89, 89, 89); font-size: 14px; font-family: 微软雅黑, &#39;Microsoft YaHei&#39;; box-sizing: border-box !important; word-wrap: break-word !important;">高标号的刹车油不能用低标号的代替，低标号的刹车油可以升级成高标号的，但不同标号的刹车油不能混用，需要完全更换。DOT3目前用于一些低端车辆，DOT4则是主流大多数车型的制动液标号。</span></p>

		<title>5款汽车刹车油检测报告三：综合评价博世较佳</title>

				<description><![CDATA[<p>制动液是重要的汽车保养产品，其对汽车制动系统的影响却至关重要。据深圳深福源信息咨询有限公司统计，2013年中国汽车制动液配套用油市场容量为1.2万吨左右，制动液流通市场年用量在1.5万吨，不过目前市场上销售的高档汽车制动液不足一半。<br/><br/>在目前的市场上，主流的品牌包括博世、埃克森美孚、中国石化长城安诺、奥吉娜及一汽大众原厂等，《消费者报道》此次即对这5个品牌的5款制动液进行了对比测评，综合本刊对5款汽车制动液的检测发现，国外品牌博世的综合评价最佳，而民营品牌奥吉娜的制动液质量堪忧。<br/><br/>综合评价奥吉娜垫底<br/><br/>本刊选取了市面上销售情况较好的国内外知名品牌，包括博世、埃克森美孚、中国石化长城安诺、奥吉娜及一汽大众原厂的DOT4制动液，在第三方实验室进行干湿平衡回流沸点、蒸发性、-40℃运动粘度、腐蚀性和橡胶适应性六项基本指标的检测。在此基础上，本刊综合了各项指标的测试结果，给出了五款制动液的综合排名，以供消费者选购参考。<br/><br/>根据各项指标的综合表现，博世和一汽大众原厂制动液的品质最好，其次是中石化长城安诺制动液。同为外资品牌的美孚表现较差。而作为中国第一制动液生产基地的民营奥吉娜垫底。<br/></p>
<p style="text-align: center"><img src="http://www.autoju.com/wp-content/uploads/2014/09/5款制动液综合评价.jpg" title="5款制动液综合评价.jpg"/></p>
<p><br/><br/>考虑到干湿平衡回流沸点和运动粘度这三项基本指标能直接反映制动液抗高温、抗气阻的能力，因此这三项在综合评测中所占比重稍大。<br/><br/>另外，蒸发性能这一指标争议较大。国家石油石化产品质量监督检验中心工程师闻环对本刊记者解释，“虽然，我国制动液标准中强制规定了蒸发性能，但美国标准已经取消检测蒸发性能这一指标。”<br/><br/>长城润滑油制动液技术主任曹毅则认为，美国标准中取消蒸发性能是因为他们的制动液抗高温性能已经是高标准，蒸发性能都能合格，检测结果已不能代表制动液的品质。但中国制动液水平还达不到这个高度，检测蒸发性能对判别制动液抗高温优劣还是很有帮助。<br/><br/>国产民营品牌奥吉娜的制动液在-40℃运动粘度和橡胶适应性这两项性能上欠佳，因此综合评价中也排名最后。沈阳奥吉娜事业有限公司一名李姓技术主任对此结果向本刊作出回应：“作为中国第一制动液生产基地，我们的配方甚至有些原材料都是自己生产的，质量不至于有什么问题。当然，我们也在不断地创新、改进配方，希望做到更好。”<br/><br/>制动液民营企业发展难<br/><br/>中国制动液市场上外资、国企、民营三足鼎立，竞争非常激烈。<br/><br/>中石化长城安诺制动液作为一家大型国有企业，在中国制动液市场一直具有指导性作用。2011年它的市场占有率已高达20%左右，至今已经进入国内30余家汽车厂家OEM领域。 <br/><br/>国外企业博世和美孚依靠其品牌效应，在中国制动液市场上也有不俗的地位。博世就依靠其1,300多家专业汽修维修站，及其制动创新技术（例如ABS、TCS以及ESP），拓宽自己在中国的制动液销路。美国埃克森美孚则一直保持着和多家豪华汽车制造商的合作关系，如保时捷、奔驰和阿斯顿马丁等，为它们提供油品及技术服务。<br/><br/>在国外大品牌与大型国企的双重挤压下，民营小厂商以期利用低廉的价格占有空缺的低价制动液市场。然而，在每年各省市的流通领域商品抽检中，民营企业生产的制动液质量难以保障，不达标情况严重。<br/><br/>长城安诺制动液技术主任曹毅提醒消费者：“制动液其实并不像汽车的汽油、润滑油更换得如此频繁。厂家规定两年4万公里一换，质量好的制动液甚至用三年也没问题。它的价格也不贵，一桶大概也60-70元，平均下来每月花费仅几元。所以，消费者应尽量选择大品牌、有产品标示的制动液。如果选用质量不好的制动液产品，可能侥幸没有出问题；但是一旦出现问题，就是再也不可挽回的大问题，危及人身安全，即使它的概率可能只有百分之几、千分之几。”<br/><br/></p>
