电子油门与CAN-BUS

    电子油门

 

    接下来我们要谈一下跟发动机息息相关的部件,我们称为电子油门。你一定要去问是不是要采用电子油门?那么电子油门有什么好处呢?在这里在座的有没有比较了解的,为什么用电子油门?我用最简单的马上就让各位可以牢记的说明,就是说电子油门在油耗调解会比较正确,各位知道油气跟空气的混合比是多少?14.7:1,那么如果你使用的是电子油门的话,他它会帮你调解成符合这样的调动,让你给油的时候,效率会比较高,不会造成无味的损失和浪费,所以一部好车就要先问发动机是不是电子油门的,油耗低,更重要的是噪音小。

 

    CAN-BUS

 

    接下来谈一下CAN—BUS,至少在25万之上的车辆才能配备这样的组件,我来说明什么是CAN—BUS,我用最简单的话让各位可能了解的,过去把发动机打开以后,可以看到一连串的线路,这些线路全部没有了,变成一条光纤,如果我把它剪断,变成两头的话,如果不碰,你马上可以看到有亮光,传输速度非常快,它的成本自然不在话下,非常高。各位可以想到,这个东西在一部车里链接的时候,如果还要一大把线路,线路是不是包装的,塑胶的,而且里面包有铜丝,那么塑胶用久了以后会老化,更何况车在行使的过程中温度那么高,所以塑胶会破损,就会产生短路现象,所以使用一年两年三年以上的车的时候,不是这里就是那里出毛病,其实都是线路出问题,现在把这些线变成一条光纤,第一,当我们打开车盖的时候,只有一条光纤;第二,没有线路老化,会产生故障、产生短路的现象,但是成本会非常高,基本上我们要用局域网控制系统。越高档的车里面的CAN—BUS越多,有两个、三个、四个,当然价位不一样,现在我们看到的25万以上的车才有这个东西,不要小看这个东西,其实他是一个模块,这个模块里面有很多开关,零组件、接口,如果这两个模块之间要连接的时候,只剩下这一条光纤,所以传输快,不会出问题,因此在选择的时候,先问你这个车辆有没有CAN—BUS的设置,如果没有,保证它的科技、成本还达不到标准,因此还不能称之为好车。
