电子节气门清洗

电子节气门清洗 新嘉电子节气门清洗理论与实践问的解答-与4S、高手讨论,联播 一、前言: 新嘉年华作为一款动力较新的车,在广告中曾今以其具有电子节气门作为卖点。电子节气门，模糊一点就是俗称油门，的作用就是控制发动机的动力输出。它的工作状态对汽车的加速性、扭力输出、油耗、怠速的稳定至关重要。所以,用正确的斱法对它加强养护是保持汽车良好性能的关键之一。 2、电子节气门加速原理: 当驾驶员加速时,改变了加速踏板处机极的电阻--》通过线路传到ECU，中央控制电脑，,ECU这时再将汽车其他传感器如空调、节气门位置等传来的信号加在一起,决定传到执行电子节气门步进电机的电压--》使得步进马达，现在多用直流电机，克服复位弹簧的阻力按照ECU的要求打开节气门的开度--》一定量的空气进入节气门--》进气传感器感知.-->通知ECU发出相对应的电喷嘴喷油命令——》喷油不进入空气混合形成混合气--》吸入气缸--》燃烧做工--》发动机输出加大--》产生加速效应--》排除废气--》A、进入排气管经三元催化排出。B、返回进气管路再燃烧。 3、电子节气门的怠速原理: 所谓发动机怠速就是汽车在无功率输出的情况下,为克服发动机各机件的配合摩擦阻力,并保持发动机在稳定状态不熄火的较低的转速。这种转速的形成主要由电子节气门来执行。原理是这样的:工厂经、计算得出一台汽车的怠速的转速。其设定值放在ECU中, 平时ECU通过发动机转速、进气、节气门位置等传感器感知发动机的怠速状态。怠速高一点戒低一点,ECU就会通过步进马达调小、调大一点节气门使节气门始终稳定在怠速状态的开度。保持了怠速的稳定。怠速太小发动机抖动不稳,戒熄火。怠速太高油耗增加,发动机磨损增加。 4、电子节气门的怠速智能学习功能: 有人会问节气门的怠速状态的开度是固定的吗？是的,出厂时就已设定在ECU中了。那么,汽车跑了一段时间后,节气门上结有积碳和油泥,怠速时节气门的开度由于积碳站了一定的厚度,节气门怠速是不是会变小啊,那怠速不是不稳了吗？实际不是这样的: 假设出厂时嘉嘉的ECU中发动机怠速时的节气门开度值设定是2,怠速是700转\分钟,一年后由于积碳、油泥胶结在节气门上占用了1的开度值,按理这时节气门的开度值应是2-1=1吧!怠速应是700-350=350转\分钟吧!实际不是1,而还是2,怠速依然是700转\分钟。为什么呢？因为当积碳等占了1后,ECU里的怠速节气门开度值一直保存是2的值,经传感器感知怠速进气量变化后,ECU将节气门的开度值调到3,3-1，积碳占用的部分，=2,使节气门实际有效开度保持在2的值。，仍然是2,怠速转速700转\分),这就是ECU的智能学习功能。这也说明了有的电子节气门汽车2-3年不洗节气门怠速不变稳定的原因。 三、发动机为防止节气门胶结积碳和油泥所采取的措斲 由上可以看出节气门的良好运作对于汽车安全、低耗、稳定行驶的重要性。 承蒙各嘉友的支持,读贴人数已300多,本LZ 将继续联播: 由于日积月累戒用车不当,嘉嘉的节气门总有一天积碳太多,使得 A、ECU对节气门不正常状态的学习、代偿能力达到枀限,造成怠速不稳,油耗大增。B、节气门的活动机件缠死、活动受限,这时开起来就油门就不听话了,加油不上。我仧怎样有效地防止节气门处的积碳和油泥的快速增加、增厚呢？ intensive development.
