问:粗糙的闲置和RPM波动

on2016年11月22日

Helle在那里我有2006 Audi A4 Turbo Manuel时,当我击中Gas Pedal rpm上下时,汽车上有些有趣的事情,并且失去了不断执行每一个齿轮装备的力量(1-6),您能告诉我什么应该是什么?

我的汽车有156000英里。

这可能是映射传感器故障的迹象。歧管绝对压力(MAP)传感器感应发动机负载,并生成与进气歧管中真空量成正比的信号。然后,发动机计算机使用此信息来调整点火时间和燃料富集。当发动机努力工作时,进气门会在油门开放时掉落。发动机吸收更多的空气,这需要更多的燃料来保持空气/燃油比平衡。当计算机从地图传感器读取重载信号时,它会将燃油混合物调节比正常情况稍丰富,因此发动机可以产生更多的功率。然后,计算机将稍微延伸(退缩)点火时间,以防止爆炸(火花敲击),从而损坏发动机并降低性能。这也可能是由其他密切相关的组件引起的,例如脏或失败的质量空气流传感器,故障的油门位置传感器或潜在的真空泄漏。我建议让您的机械专家来到您的位置万博体育入口diagnose and replace your MAP sensor
