What are the consequences of car exhaust pipe blockage?

What happens when the exhaust pipe of the car is blocked? If the exhaust pipe is completely blocked, you won't be able to start the car. If it is not completely blocked, you can still start the car. But in the process of driving, you will feel that the speed is weak and the power is not smooth. In the long run, engine carbon deposition increases, fuel consumption increases, and engine life is shortened.

First of all, we should know that the function of the exhaust system is equivalent to the respiratory system of the human body, and its significance is self-evident. If a person can't breathe, he will die in a short time, and so will a car. An automobile engine sucks outside air into the engine.

Then use it to do work, turn waste into treasure and then discharge it through the exhaust pipe, so the role of the exhaust pipe is very important. In order to have a higher speed, the owner will choose to step on the accelerator deeply to improve the speed.

The throttle valve will open, and the ECU will detect the opening of the throttle valve and control the transmission to downshift forcibly. Therefore, the owner of the car found that the downshift was hanged, generally because the exhaust pipe was blocked, and there would be tempering when the engine refueled.

When the engine exhaust is not smooth, some exhaust gas will remain in the cylinder, diluting the mixture and slowing down the combustion speed. When the intake valve is opened, the mixture is still burning, and the burned mixture will flow back to the intake pipe through the opened intake valve, resulting in backfire.

If the exhaust pipe is blocked, the exhaust gas will not be discharged in the final exhaust stage, which will also hinder the good progress of the intake stage and the engine will stall. This is a completely blocked situation. In fact, the exhaust pressure of the engine is very high, and it is generally not easy to be completely blocked. What if the engine is not completely blocked?

That is, the engine exhaust is not smooth, because too much exhaust leads to insufficient power in the next stage, and the fuel injector will increase the fuel injection quantity to ensure power, so further carbon deposition will occur. In addition, due to the high temperature of exhaust gas, if it cannot be eliminated in time, it will lead to overheating of the pipeline and endanger other components.

So if the engine is blocked because of a prank, there will still be big trouble. High temperature exhaust gas must be completely discharged from the cylinder, but once the exhaust pipe is blocked. When the exhaust valve is closed, the exhaust gas cannot be completely discharged from the cylinder, but the piston in the cylinder will continue to push upward, and the exhaust gas will be squeezed out from the intake valve and even the cylinder gap.

The so-called backfire ignition phenomenon has been caused, and the damage has been formed, so it must be sent for inspection and repair. But who would have thought that the cause of this phenomenon is not the engine, but the exhaust pipe. It is generally believed that the cause of tempering blasting is caused by some faults in fuel injection system and ignition system.

However, it is always ignored whether the exhaust gas cannot be discharged smoothly due to physical reasons and is squeezed elsewhere. When the engine is turned off, the exhaust gas flows evenly and there is no "sudden" sound. When the engine exhaust is seriously blocked, the cylinder-broken test will find that the engine jitter is obvious, but the exhaust gas flow in the car is very uniform.

There is no "sudden" engine cylinder number because of insufficient air. This is because the blocked exhaust pipe greatly attenuates the fluctuating exhaust gas flow caused by the lack of cylinder in the engine, thus causing the illusion that the exhaust gas is "moderate". What are the consequences of car exhaust pipe blockage? Exhaust pipe problems are common. You can judge by some symptoms when using a car. When maintaining and inspecting a car, you must also check the exhaust pipe of the car to prevent these problems.
