有哪些跡象表明催化轉換器失效壞了

催化轉化器的排放控制系統對車輛來說是非常重要的一部分 。它通常決定車輛排放的好壞,但偶爾催化轉換器也會某種原因失效 。如果你是司機懷疑催化轉換器失效了,你能做的最好的事情是,把催化轉化器發生故障的車輛開到維修機構進行維修 。
如果需要的話,技術人員會把車輛放到電子診斷機上找到問題的根源,可能是去除廢氣歧管或排氣管前催化轉化器的氧傳感器,看看是否有變化的東西,也可能是更換催化轉化器 。

下面這里有五個跡象表明可能是催化轉化器失效壞了:
車輛的燃油效率突然下降 。
當你踩在油門踏板上你的車輛沒有加速 。
您的車輛可能會拒絕啟動 。
您的車輛出現故障的排放測試 。
該mil或檢查發動機燈亮 。
故障在一個舊汽車的催化轉化器的最常見的原因是,它會堵塞使排氣管不讓廢氣可以通過消聲器和排氣管 。(如果空氣不能走出車輛的后部,它不能進來的前端,所以發動機模具因為沒有空氣進來以形成燃料/空氣混合物 。)
每一個自1996年以來,在美國銷售的汽車已經有一個obd(車載診斷)ii系統,測試催化轉化器(在許多其他事情) 。如果單位允許太多的污染從排氣管逃脫,它照亮了mil并產生一個故障代碼,可以用什么叫做一個技術人員來讀“掃描工具 ?!?
該催化轉換器是變化的廢氣中的內容和溫度敏感的,因此另一種可能的失敗原因是,如果氣缸蓋墊片損壞,允許油或冷卻劑進入燃燒室和氣缸被燒毀 。此外,如果您的點火系統運行不正常,在廢氣中的未燃燃料可導致催化轉化器磨損或分解 。這是另一個很好的理由在指定的時間間隔將用于調整窗口!
由于催化轉換器可能會變得很熱,重要的是您的車輛不要停放在有的干草或干樹葉的地方,這可能會引起火災和破壞不僅是你的車,而且周邊地區!

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. 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.”
