Can the car engine and fuel tank be started after flooding?

Automobile engine and fuel tank can't be started with water, and forced starting will lead to engine scrapping. When the vehicle is wading, water enters the cylinder from the intake manifold. Because of 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.

Extended data:

If the engine is only mixed with steam and water is fed from the air filter, there is no big problem at this time. We only need simple treatment to clean 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. We need to drain the water, clean it up, then reinstall it and change the oil, but the circuit system is unsafe.
