    洒水车三元催化转化器损坏的鉴别方法

    催化转化器的排放控制系统对洒水车辆来说是非常重要的一部分。

    它通常决定车辆排放的好坏,但偶尔催化转换器也会某种原因失效。 如果你是洒水车司机怀疑催化转换器失效了,你能做的最好的事情是,把催化转化器发生故障的车辆开到维修机构进行维修。

 


    如果需要的话,厦工楚胜洒水车厂家技术人员会把车辆放到电子诊断机上找到问题的根源,可能是去除废气歧管或排气管前催化转化器的氧传感器,看看是否有变化的东西,也可能是更换催化转化器。



    下面这里有五个迹象表明可能是催化转化器失效坏了:


    车辆的燃油效率突然下降。


    当你踩在油门踏板上你的车辆没有加速。


    您的车辆可能会拒绝启动。


    您的车辆出现故障的排放测试。


    该MIL或检查发动机灯亮。


    故障在一个旧汽车的催化转化器的最常见的原因是,它会堵塞使排气管不让废气可以通过消声器和排气管。 (如果空气不能走出车辆的后部,它不能进来的前端,所以发动机模具因为没有空气进来以形成燃料/空气混合物。)


    每一个自1996年以来,在美国销售的汽车已经有一个OBD(车载诊断)II系统,测试催化转化器(在许多其他事情)。 如果单位允许太多的污染从排气管逃脱,它照亮了MIL并产生一个故障代码,可以用什么叫做一个技术人员来读“扫描工具。”


    该催化转换器是变化的废气中的内容和温度敏感的,因此另一种可能的失败原因是,如果气缸盖垫片损坏,允许油或冷却剂进入燃烧室和气缸被烧毁。 此外,如果您的点火系统运行不正常,在废气中的未燃燃料可导致催化转化器磨损或分解。 这是另一个很好的理由在指定的时间间隔将用于调整窗口!


    由于催化转换器可能会变得很热,重要的是您的车辆不要停放在有的干草或干树叶的地方,这可能会引起火灾和破坏不仅是你的车,而且周边地区!

The catalytic converter is a very important part of the emissions control system on your vehicle. It’s usually good for the life of a vehicle, but occasionally it does fail. The best thing you can do is be alert for signs of trouble and head for a service facility if you suspect that the catalytic converter is malfunctioning.


Technicians will put your vehicle on an electronic diagnostic machine to locate the source of the problem, possibly remove the oxygen sensor from the exhaust manifold or exhaust pipe ahead of the catalytic converter to see if that changes things, and replace the catalytic converter, if necessary.


It’s against the law in many states to remove a catalytic converter and run a vehicle without one.

Interior and exterior views of a catalytic converter.

Here are five signs that something may be wrong with your catalytic converter:


Your vehicle’s fuel efficiency suddenly drops.


Your vehicle doesn’t accelerate when you step on the gas pedal.


Your vehicle may refuse to start.


Your vehicle fails an emissions test.


The MIL or Check Engine light comes on.


The most common cause of failure in a catalytic converter in an older car is that it becomes so clogged that the exhaust gases can’t get through it to the muffler and out of the car. (If air can’t get out the rear of the vehicle, it can’t come in the front end, so the engine dies because no air is coming in to form the fuel/air mixture.)


Every car sold in the United States since 1996 has had an OBD (On-Board Diagnostic) II system that tests the catalytic converter (among many other things). If the unit allows too much pollution to escape from the tailpipe, it illuminates the MIL and produces a trouble code that can be read by a technician with what’s called a “scan tool.”


The catalytic converter is sensitive to changes in the contents and temperature of the exhaust gases, so another possible cause for failure is if the cylinder head gasket is damaged, allowing oil or coolant to get into the combustion chamber and be burned in the cylinders. Also, if your ignition system isn’t operating properly, unburned fuel in the exhaust gases can cause the catalytic converter to wear out or break down. This is another good reason for going for tune-ups at specified intervals!


Because the catalytic converter can become extremely hot, it’s important not to park your vehicle over a bed of dry grass or dry leaves, which could catch fire and destroy not only your vehicle but also the surrounding area!
