大家去4S店保养的时候,经常需要换的就是所谓的“三滤”,三滤究竟是什么,应该多久换一次呢?
汽车三滤指的是:机油滤芯、汽油滤芯和空气滤芯。下面为大家详细介绍:
机油滤芯
机油滤芯主要作用是过滤机油,包括:灰尘、金属磨屑、胶质、油泥等,保证机油的清洁。
如果机油有杂质的话,会加速气缸和活塞的磨损,也容易造成油路堵塞。
机油滤芯每次保养都要随机油一起更换。
汽油滤芯
汽油滤芯的主要作用是过滤汽油,汽油在储运及加注过程中,难免会混入一些杂质和水分,汽油滤芯作用就是过滤掉这些。
如果这些杂质随着汽油进入供油系统中和气缸内,会加速气缸磨损。
汽油滤芯每三次保养更换一次,如果是新车,第三次保养的时候更换,下一次就是第六次。
空气滤芯
空气滤芯的主要作用是过滤进入气缸的空气,空气中有很多灰尘、如果进入气缸,会大大加速气缸、活塞的磨损。
空气滤芯也是每三次保养更换一次,如果是新车,第三次保养的时候更换,下一次就是第六次。
还有一个空调滤芯,也要经常换
空调滤芯的主要作用是过滤进入空调空气,保证车内空气的清新,作用和家用空气净化器的滤芯作用一样。
所以如果您开车窗,打开空调的外循环、空调开启一段时间之后,车内的空气质量都会非常好,PM2.5基本都会在50以下。
空调滤芯需要一年换一次,如果您当地的空气质量比较差,就需要半年换一次了。
