Detect whether the three-way catalytic converter is dismantled

We can knock the shell of the Shen Yuan catalytic converter and hear the sound it makes to judge. Generally, the hollow catalytic converter will make a sultry sound, and the brittle three-way catalytic converter will make a crisp sound, or check the three-way catalytic converter. The clear sound of the device confirms whether the detector exists or not. There are three types of fault detectors. From the exhaust pipe detector, it is fully cooled and stretched, and it is found whether the original device has a ternary detector. There is a situation that is usually sold: the first type of catalytic converter is peeped, because the three-way catalytic converter is damaged and valuable. The second type is that the decomposer is damaged. For daily use, it is directly dismantled and dismantled.The three-way catalytic converter is generally divided into two situations. One is to dismantle the original car’s three-way and replace it with a subsidiary factory’s three-way. This situation is not easy to detect. You need to climb to the bottom of the car to see it. The surface of the replaced ternary is a normal metallic color. After a long time of high temperature baking, the old ternary of the original car has turned into a khaki color, which is easy to see. Another is to directly poke the precious metal material in the old ternary. Come out, in general, the engine noise of the car will become louder, and the smell of the exhaust will be very pungent and unpleasant.
