Engine water intake is definitely a fatal internal injury to the car. Once the car engine water enters, the spark plug cannot be ignited or even directly extinguished, and the cylinder is exploded, no matter what the situation, the car owners certainly do not want to encounter. Nowadays, rainstorms are common in many places across the country, and it has become normal for a large number of cars to be flooded. Therefore, the number of damaged vehicles is also increasing. The main reason for the damage is the water in the engine, which causes the vehicle to stall or burst the cylinder! So how should we judge the engine water intake, and how should we deal with its harm?
How to judge the water intake of the engine
Now that most people understand the hazards of engine water ingress, how do you tell if the engine has water ingress? The easiest way is to check whether the color of the engine oil is abnormal. If the engine oil turns milky white, it means that water has entered the fuel tank or the engine.
Secondly, it is necessary to check whether each pipeline is filled with water. Including air filter and air filter lower shell, whether there are more obvious signs of water ingress, and check the intake pipe and intake manifold for obvious signs of water. Finally, check the spark plug and the cylinder wall of the engine for carbon deposits. Remove the spark plug of each cylinder and check whether it is wet. When the engine is working normally, the position of the piston of each cylinder reaches the top dead center. The position of the top dead center of the cylinder wall (compression residual Gap) clear. After the engine is filled with water, because the water is difficult to be compressed, the piston cannot reach the original top dead center position, the piston movement stroke becomes shorter, and the top dead center position will move down significantly.
As we all know, when the vehicle wades into the water, the water enters the cylinder from the intake manifold. Due to the incompressibility of the water, the piston travel will become shorter, causing the engine connecting rod to bend or break. In extreme conditions, the broken connecting rod will fly out Break down the cylinder. The reason why the car flames out in the water is that the distributor cover loses its normal ignition function after entering the distributor cover. The engine air filter element is immersed in water, resulting in increased intake resistance and water in the combustion chamber. The spark plug cannot be ignited. If the engine is restarted at this time, it is easy to explode the cylinder.
If water enters the engine, water will also enter the engine oil, which will cause the engine oil to deteriorate and change its original performance. In this way, the engine oil cannot play its lubricating, cooling, sealing, anti-corrosion and other functions, and the engine is ultimately injured.
What to do if the engine enters the water
Engine water intake is a big trouble, so how should we deal with the engine water intake? The most important thing to remember is not to force the vehicle that has been turned off forcibly. When the vehicle travels on a pavement, if the vehicle is turned off due to water in the exhaust pipe, you must not rush to restart. Because when the vehicle is flooded, restarting will often cause damage to the engine and cannot be compensated.
At this time, the owner should push the vehicle out of the deep water area to ensure that the engine air intake will not suck in water and stop in a safe place. Remove the distributor cover, dry the cover with paper towels, and reinstall. If the water enters the air intake, you must replace the air filter and remove the spark plug to drain the water in the combustion chamber.
First open the engine cover, unplug the sub-cylinder line, remove the spark plug, and then start the engine, the water in the engine cylinder will be discharged from the engine through the hole of the spark plug, hold the key in the starting position for 5 seconds, then release, wait 10 seconds Start the engine for 5 seconds after the clock, so 3 times, you can basically drain all the water out of the engine. However, if the engine does not rotate when starting after removing the spark plug, it means that the engine is dead and can only go to the service station for treatment.
The main points of claims for engine water intake
1. If the vehicle is flooded at a standstill, it is caused by the owner's failure to force it, the insurance company will be responsible for compensation.
2. If the vehicle is involved in water shut-off, the insurance company is not responsible for compensation once the engine is flooded, regardless of whether the owner starts again.
3. Compensation will be awarded for damage to the engine water intake during heavy rain, and no compensation will be paid if the vehicle is flooded due to driving in normal weather.
4. After the flame is turned off in the water, it will not be damaged if it is started again.
