For Ford Focus 1.5L 2015 2014-2017 Ford Fusion Turbo 1.5L catalytic converter

The laboratory is equipped with advanced instruments such as small sand mills, analytical balances, pure water machines, ovens, high-temperature muffle furnaces, ultrasonic cleaning machines, and constant temperature water baths. It is mainly used for routine chemical analysis of raw materials, catalyst process development and optimization, and sample preparation and their testing process.

If the three-way catalytic converter is broken, what effect will it have on the car?

1. The car makes abnormal noise

The first phenomenon is that if the three-way catalytic converter is bumped and dragged to the bottom, it may cause crushing, breaking, and some abnormal noises. When the car is on the spot or the fuel is on the spot, there will be some booming noises.

2. The engine fault light is on

If the conversion efficiency of the three-way catalytic converter is low or fails, all you can see is that the engine fault light will come on. The fault code may be P0420 or P0421, and it is reported that the conversion efficiency of the three-way catalytic converter is low. At this time, we need to replace it.

When idling, a small amount of mixed gas in the engine will not be completely burned and will directly enter the exhaust system. If the idling time is too long, the exhaust system will continue to heat up and burn out the three-way catalytic converter. Therefore, it is important for drivers to avoid idling for long periods of time as much as possible. At the same time, the three-way catalytic converter should be checked regularly (can only be operated after the temperature has dropped). If there are traces of high-temperature burning and abnormal color, it means that the catalytic converter has been overheated and the working effect has been reduced.

Because there is an oxygen sensor in front and behind the three-way catalytic converter in the car, which senses the oxygen content in the exhaust gas. Generally, if it works normally, the oxygen content of the front end is higher than that of the rear end; if it is not installed, the oxygen content of the front and rear ends is the same, then the signal sent by the oxygen sensor to the electronic control unit is that the oxygen content is too high, and the electronic control unit will judge that the oxygen content is too high. The mixture is too thin, thereby increasing the amount of fuel injection, making the mixture too rich, and increasing the car's fuel consumption. Therefore, it is not advisable not to install a three-way catalytic converter.
