How to maintain the car after water intake maintenance?

If the engine is only mixed with water vapor, it is not a big problem at this time. It only needs simple treatment to clean up the water vapor in the air filter, throttle and cylinder.

If the engine has a lot of water, but it does not affect the normal running, but the sound is relatively loud, it may be that there is a small amount of water in the engine oil and gasoline, so it is necessary to change the engine oil and clean the engine related accessories.

If there is a lot of water, it means that the engine is close to water, not mixed with water, but the car did not start and the engine was not damaged. It is necessary to drain the water and clean it up, then reinstall it and change the oil with it, but the circuit system is unsafe.

If the engine has too much water and can't run after starting, and the cylinder, connecting rod and piston of the engine have been deformed, then it can be considered that the engine has been scrapped and can only be replaced with a new engine, or the car can be scrapped directly.

Method for judging engine water inflow;

The easiest way is to check whether the color of the oil is abnormal. If the oil turns milky white, there is water in the oil tank or engine.

Secondly, check whether the pipeline is flooded. Including air filtration and air filtration, whether the lower shell has obvious water intake traces, and check whether the intake pipe and intake manifold have obvious water intake traces. Finally, check whether there are traces of carbon deposits on the spark plugs and engine cylinder walls, and remove the spark plugs of each cylinder to check whether they are wet.

When the engine works normally, the pistons of each cylinder reach the same top dead center position, and the top dead center position (compression gap) of the cylinder wall is clear. When the engine enters the water, because the water is difficult to compress, the piston cannot reach the original top dead center position, the piston motion stroke is shortened, and the top dead center position will move down obviously.

As we all know, when the vehicle is wading, water enters the cylinder from the intake manifold. Due to the incompressibility of water, the piston motion stroke will be shortened, which will lead to the bending or fracture of the engine connecting rod. In extreme cases, the broken connecting rod will fly out and puncture the cylinder.

The reason why the automobile flameout in water is that the distributor loses its normal ignition function after the distributor cover is flooded, and the engine air filter element is flooded, which leads to the increase of intake resistance, the combustion chamber is flooded, and the spark plug cannot be ignited. If you restart the engine at this time, it is easy to explode.

If the engine is flooded, the engine oil will also be flooded, which will lead to the deterioration of the engine oil and change its original performance. In this way, the engine oil can't play its functions of lubrication, cooling, sealing and anti-corrosion, and ultimately it will hurt the engine.
