Hydroat the engine of the car is extremely rare phenomenon, but in the absolute majority of cases it ends with very serious consequences. During the adopted protective measures allow us to avoid the effect of the hydroudar and its negative consequences.

Hydroat, what it is

The effect of the hydroudar occurs due to the fall of a large amount of water directly into the cylinder. The thing is that water is practically not amenable to compression. When water enters the cylinder and its number more than its volume, at the time of its stay in the upper dead point of the compression tact, the effect of the hydroudar occurs. The piston under the influence of colossal kinetic energy is trying to compress the volume of the cylinder, and the water elementary does not allow it to do. As a consequence, the engine elements bend, burst and break.

Interesting! "Hydro" is translated from Greek as "water", that is, the words "Hydroat" means "water blow."

Water enters the engine cylinders directly through the air intake. And it is not necessary to overcome the rivers and streams to the water to get water at all. Sometimes it may occur even in the urban environment, it is enough to just overcome the larger puddle at high speed.

Important! In addition to the water, the cause of the hydroudar also has a motor oil, which enters the cylinder, after breakdowns of the turbine.

Consequences of hydroudar

The effects of the hydraulic man can be diverse. Sometimes after the effect of the hydroudar, it is much more profitable to replace the power unit of the car than its overhaul.

After receiving the hydraulic man, the following faults may occur:

• Deformation of the connecting rod;
• Deformation of the piston;
• Engine jamming;
• File breakdown;
• The deformation of the crankshaft;
• Damage to the cylinder block (up to its punching).

The consequences and their strength depends on the 3 main factors, namely:

1. The amount of water that fell into the cylinder;
2. Car engine power;
3. The number of engine revolutions at the time of the hydrowood.

Important! If after receiving the hydraulic man no action, but it is to make repair and restoration work and replace damaged parts. The consequences can become more worse.

Protective measures, advice of professionals, how to prevent hydrowards

• Premiss the occurrence of the hydrowards is quite easy. For this, it is enough to adhere to not difficult rules:
• Try to avoid flooded places and large puddles more than 10 centimeters. It is also worth avoided the puddle depth, which cannot be determined;
• When crossing the puddles, reduce the speed of the car to a minimum, and carefully drive it;
• If there is almost a tropical shower on the street better to rein the weather at home. If you are already on the way, it is worth stopping and wait until the rain intensity will decrease a little;
• It is extremely recommended to start a car after flooding. In particular, if his front part was under water (even short time);
• It is also not recommended to start a car. If it is stalled, when overcoming a puddle or a stream, as well as after them.

driver's actions that the driver should do if the car stalled after the puddles

As already mentioned above the car in no way should be re-start. Ideally, if you are in a draw or near the settlement, it is better to call a tow truck. In order for him to deliver the car to a specialized auto repair shop, where they dry out both cylinders and the entire power unit of the car as a whole.

The ability to call the tow truck is not always available, in the same case follows:

Turn off the ignition;

1. If the car is in water, then, first of all, it should be pulled out of it;
2. Disassemble directly air filter, since it is through it most often water gets into the engine. If there are footprints in the air filter, it's worth moving to the next step, if not, we collect everything into place and try to start the car;
3. Remove all spark plugs;
4. Turn the crankshaft, if a little water comes out through the candle holes - this means that the water is already directly in the engine and the car cannot start the car in any way.
5. If there is no water, screw the spark plugs and collect everything into our places;
6. We try to re-start the engine.

Important! If the front of the car stayed under water more than 10 seconds. With a probability of 99.9%, it can be said that the water fell directly into the engine.

If water, still got into the car engine. Its in no way should be started. Such a car is necessary on the towing to deliver to the auto repair shop for subsequent drying.

Important! Ignoring water in the engine will lead to the mass of negative consequences. Even if it does not hide.

It also happens quite often that the reason why the engine stalled is the sensors and car wiring.

Signs of the hydroudar, which will indicate the engine

The hydroudar can be judged by the characteristic sound when the water obstacles passes, or after them. In addition, the car after the hydraulic man is usually stall.

Hydroat on the engine of the car can not always be seen. Sometimes it happens that during the hydrought the car does not stall and quite adequately behaves for a long time (up to 10 thousand kilometers). All this time, the wear of the force aggregate is accelerated and leads to sad consequences.

On the transferred hydraulic man, it can be judged by the following features:

• The deformation of the air filter with a high probability says about the hydroudar;
• Immediately at the bottom of the piston there are two layers of deposits. The first thing is Nagar, deposited before hitting. Second, respectively after;
• Deformed connecting rods;
• Uneven wear of the inserts occurs, which is not even armed with an eye;
• Education on the piston skirt of scuffs, scuffs and nagar in unusual places for it.

Tips of professionals

• To reduce the likelihood of the hydraulic man, you should not go through the deep puddle, rivers and streams. It should always be adequate to evaluate the possibilities of your car. If the SUV car is able to go through a deep stream - this does not mean that it will pass without consequences and sedan;
• You should not try to start a flooded car, with a high probability of water already got into it and this attempt will not lead to anything good;
• Safe speed when overcoming deep puddles 7-10 km / h. This speed allows you to quietly go through the puddle, minimizing the likelihood of water in the car engine;
• In case, in the way you found a strong shower. It is recommended to stay in a safe place and wait for it, at least until it subsides a little;
• If water gets into cylinders, it also falls into the crankcase. Mixed with butter, as a result, when the water gets into the engine, it must also be replaced;
• Water that fell into the car engine is a serious problem. With which it is worth contacting the specialized car repair shop. In the auto repair shop dried both the engine cylinders and all other elements;
• The consequence of hydraulic for cars with a diesel engine is usually heavier. This is due to the smaller size of the combustion chamber;
• As a rule, after the underwent hydraulic man. When applying for warranty in a car dealership, where the car was purchased. Car dealers argue that this is not a warranty case and refuse to produce free repair and restoration work. There are cases that car owners through the court proved the warranty of this case and received free repairs.
