1. exhaust emissions exceed the standard
CO, HC and NOx and other harmful gases are directly emitted, certainly exceed the standard.
2. Fuel consumption increases
The blockage of the three-way catalytic converter will affect the normal operation of the oxygen sensor, which also affects the accuracy of the oxygen sensor signal received by the engine, so that the injection, intake and ignition can not be accurately controlled, and the fuel consumption will increase.
3. exhaust is not smooth, power decline
This is more obvious on the turbocharged model, after the three-way catalytic converter is blocked, when the high-pressure exhaust is needed, the exhaust is not smooth due to the blockage, which affects the intake volume, and then leads to the engine power decline, and then leads to the power decline, the refueling is weak, and the running will have a feeling. In this respect, at this time the power drops, in order to obtain the same power output, the driver will certainly increase the throttle, which will also lead to increased fuel consumption.
4. engine jitter, fault light, often flame out
When the three-way catalytic converter is seriously blocked, due to the failure to discharge the exhaust gas in time, it will inevitably cause the back overflow, and when the pressure exceeds the pressure value of the engine discharge, the backflushing to the combustion chamber will make the engine shake, gasp until the flame is extinguished.
5. Spontaneous combustion
The normal working temperature of the three-way catalytic converter is generally 400-800 ° C, once blocked, affecting the exhaust gas, so that the high-temperature gas accumulation, resulting in the three-way catalytic converter, exhaust pipe continues to heat up, when the temperature rises to the ignition point of the adjacent components or the object that is relatively easy to light touches the red exhaust pipe, then it is easy to spontaneous combustion.
6. automatic transmission vehicles forced downshift frequently
Because the exhaust blockage causes the engine power to decrease, the driver in order to make the car have more power output, it must step on the accelerator deeply, so that the throttle valve is wide open, so the ECU controls the automatic transmission according to the open state of the throttle valve.
