什么是92汽油?什么是95汽油?
92号汽油就是指辛烷值不低于92的汽油。95号汽油就是指辛烷值不低于95的汽油。接下来我们将认真讲解一下两种汽油。
1.什么是辛烷值?
在了解两款汽油之前,我们必须要了解这辛烷值是什么东西,因为辛烷值是区分汽油的重要标志。辛烷值官方的说法是:指汽车所使用的燃料抵抗震爆的指标。换句话来说,就是这种燃料能压制震爆的能力。这个数值越高,说明这种燃料在压制震爆的能力越强,更不容易损坏发动机。
2.92号汽油
92号汽油就是辛烷值不低于92的汽油。这个是所有汽油里面最垃的汽油。很多入门级轿车和性价比轿车都是使用的这种汽油,这种汽油的抗爆性不好,长期使用会损坏发动机,不过没关系,在发动机的使用期内,除了会逐年使汽车性能下降之外,都不会对你的汽车造成什么影响的。所以不用担心这个问题。但92号汽油有一个致命缺点,那就是对环境的污染大。
3.95号汽油
95号汽油就是辛烷值不低于95的汽油。别看只数字只大了3,但在各方面都领先92号汽油。而是现在是我国的主流汽油,我国因为环保政策,对车辆的排放要求更加的高了。因为95号汽油对环境造成的污染比92号汽油小得多,所以现在越来越多的汽车使用了95号汽油,这样就可以完美符合我国的国标,不然的话不给汽车上市。而且使用了95号汽油之后,不会有92号汽油那样的缺点,不管使用多久的95号汽油,其对汽车的性能影响是微乎其微的。
总的来说,92号汽油就是指辛烷值不低于92的汽油。95号汽油就是指辛烷值不低于95的汽油。 这也是官方的定义,没什么可说的。
汽油的标号92号95号98号代表什么?
95、98是加油站售油时提供的三种型号的汽油的标志。
92号油一般适用于中低档轿车和其他一般汽油车使用。
95号汽油一般适用中高档轿车和其他对燃油要求较高的汽车使用。
98号油则适用更高档轿车和特种车使用。
总的来说,是三种不同标号汽油的标识。
更多解释:
1、不同标号的汽油服务于不同要求的发动机。
2、发动机根据车辆设计出不同抗爆性,以满足行车的要求。
3、汽油为了满足发动机的要求,通过辛烷值的不同,形成了92 95 98号汽油。
4、92 95 98汽油是服务于不同类型发动机的要求。
92号汽油95汽油的区别在哪?92 95汽油有什么区别
; 92号汽油和95号汽油的区别只是辛烷值不同。辛烷值是代表汽油抗爆震燃烧能力的一个数值,辛烷值越高抗爆性越好。标准燃料由抗爆性非常好的异辛烷和抗爆性很差的正庚烷组成,其辛烷值是100。
汽油标号是实际汽油抗爆性与标准汽油的抗爆性的比值。92号汽油标号是指该标号汽油与异辛烷92%、正庚烷8%的标准汽油具有相同的抗爆性,其辛烷值为92;95号汽油标号是指该标号汽油与异辛烷95%、正庚烷5%的标准汽油具有相同的抗爆性,其辛烷值为95;98号汽油标号是指该标号汽油与异辛烷98%、正庚烷2%的标准汽油具有相同的抗爆性,其辛烷值为98。
根据发动机的压缩比选择合适的汽油标号很重要,若高压缩比的发动机选择低标号的汽油,汽油发动机容易产生爆震,发动机长时间爆震,容易造成活塞烧结、活塞环短裂等故障,加速发动机部件的损坏;若低压缩比的发动机选用高标号汽油,虽能避免发动机爆震,但高标号汽油配低压缩比的发动机会改变点火时间,造成汽缸内积炭增加,长期使用会减少发动机的使用寿命。
