What's the matter with the car chimney slamming on the accelerator and spewing out water and black objects?

When the car slams on the accelerator, the water sprayed from the chimney is the water produced when the engine works and the water left in the exhaust pipe when washing the car. Black objects have carbon deposits in the exhaust pipe. If you step on the accelerator, the exhaust pressure in the exhaust pipe will increase, and the airflow will bring these things out.

The carbon deposit can be removed by slamming on the accelerator, which generally requires a speed of more than 4,000 rpm. If the speed of 100 km/h to 120 km/h is maintained, there will be no carbon deposit after driving for a period of time. Hard stepping on the accelerator in situ can also clean up part of it, but only part of the carbon deposit can be cleaned up. The carbon deposit in the accelerator in the engine cannot be cleaned up in this way.

Extended data

Small knowledge of removing carbon deposits from turbine engines

If the engine is over-injected, about 65,438+00% will not burn out, and carbon deposition will occur. In fact, a turbine engine car just needs to blow the throttle in place. The structure and speed of turbine engines are different. Cleaning up carbon deposits has nothing to do with your own speed.

However, frequent accelerator deflagration is more harmful to the car, the most obvious thing is that it will increase the consumption of engine oil, and it will lead to incomplete fuel combustion, and finally more and more carbon is deposited. Moreover, if the accelerator is bombarded for a long time, it will also lead to an increase in fuel consumption and a decrease in engine power.

Phoenix. If the oil sinks, all the carbon deposits will disappear? Can you remove carbon deposits by slamming on the accelerator?
