What should I do if the car is frozen by snow and can t open the door Warm water has tried it but it

After the snow stops, the lock is easy to be frozen, don't use force at this time, don't force the new car There is grease in the lock cylinder, which has a certain waterproof effect. If the owner of the car twists the key regardless of it, he can only break the key. Don't use the fire directly to bake the lock, otherwise it is easy to burn the paint around the lock.

Cope.

1. Add hot water to the water tank, and slowly the car can be started. At this time, do not ignite continuously to avoid the battery running out. The service life of the battery is generally one and a half to three years, and it should be replaced in time after this period.

2. The flow of engine oil is blocked, and the appropriate engine oil should be replaced. In winter, the viscosity of the oil increases, making it difficult for the oil to flow, which increases the resistance of the engine. The emergency solution is to put the car in a warm environment, and after a period of time, it can start normally.

1. Some old cars with a long time have electricity, but they just can't ignite, try to turn on the car and the wind, and then step on the accelerator and ignite at the same time, so that the ignition will be better.

2. If you start the car, listen to the motor rotation weakly, and even have a clattering sound, this situation may be caused by the battery power loss, if possible, use the detector to detect the voltage, if the voltage does not exceed 10 8 volts, in this case, find a car with sufficient battery power, use a conductive rope, link to your own car battery, and charge, note: to connect the battery when the positive and negative poles!

3. Because of the cold, the exhaust cylinder will be frozen when the car is driving, which can be done on the road with slopes, so that the car is in an uphill state, so that the engine idle speed reaches 3000 rpm, and it can be started by repeating 2 or 3 times.

4. The cylinder pressure is too low, and the engine is found to be normal when starting, but it just can't ignite, which may be a problem with the cylinder and the car needs to be towed for maintenance.

5. Diesel is the easiest to catch fire in winter, it is recommended not to try to save money, and mix No. 0 diesel and No. 10 diesel in winter, which is easy to freeze, resulting in the car not catching fire.

1. The battery loses power.

The main manifestation is that the starter starts to rotate but the speed is not enough, that is, the start is weak, and even the starter just clicks but does not rotate. This situation may be due to the fact that the vehicle cannot be started due to the forgetting to turn off individual electrical equipment in the car, especially for long-term short-distance use in winter, the battery voltage will be lower than the rated value, and the starting cannot operate normally. The solution is that you can hit the ** rescue, or find a car to catch fire, and after the fire, it is best to go to the repair shop to replenish the battery.

2. The flow of gasoline is blocked.

Generally, there is no oil pressure in the engine oil supply pipe, which mostly occurs in the morning when the temperature is particularly low, due to the long-term dirt of the fuel pipeline, when the temperature is particularly low, the water and debris are mixed so that the fuel pipeline is not passable, and the result can not start. The solution is to put the car in a warm environment, and the car can start in a while; Or use the method of cleaning the oil circuit to solve it completely.

3. Ignition system failure.

Due to the low intake air temperature in the cylinder, the fuel is not atomized well in the cylinder, if the ignition energy is insufficient, it is easy to lead to the phenomenon of flooding, and too much fuel accumulates in the cylinder, exceeding the fire limit concentration and unable to land. The solution is to unscrew out the spark plug to wipe off the oil between the electrodes, and it can catch fire after installation. The thorough way is to check.

1.The fluidity of the oil deteriorates, and the resistance increases.

The lower the temperature, the greater the viscosity of the oil, the worse the fluidity, and the greater the resistance of the engine. Therefore, in winter, it is advisable to switch to a less viscous oil to cope with cold weather. At present, most of the engine oil on the market uses SAE and other grades to identify the viscosity, and the more the number in front of the "W", the thinner the engine oil, the higher the low-temperature fluidity, and the stronger the cold start ability.

2.The spark plug deadline has arrived.

If the vehicle starts successfully, but there is a noticeable frustration at start, accompanied by increased idle shake and reduced engine acceleration, it is likely to be caused by spark plugs. At this point, you can start with the spark plug to check the combustion color, the gap between the electrodes, and whether there is air leakage between the porcelain and the metal housing. Generally speaking, it is not a problem for a spark plug with excellent quality to run 100,000 kilometers.

3.There are problems with the air intake, fuel injection, and exhaust systems.

Once the throttle and intake tract are dirty, it will not only cost fuel to open, but the throttle will also become sluggish and non-linear, and the car will suddenly rush forward when the throttle is increased. Dirty fuel injectors will lead to increased fuel consumption, idle shaking, and exhaust smell. In terms of exhaust, on the one hand, it is necessary to pay attention to check the three-way catalysis, and the second aspect is to pay attention to whether there is ice in the exhaust pipe.

4.The gasoline pump depressurizes.

Many car owners will encounter the situation that the first ignition fails, and the second time it will succeed. In this case, don't take it for granted that it is a problem with the battery, most of it is related to the pressure relief of the gasoline pump! The internal wear and tear of the gasoline pump after a long period of use can lead to insufficient fuel supply pressure, resulting in difficult ignition.

In general, replacing the gasoline pump will solve the problem.

5.Beware of rising freezing point of antifreeze.

Winter is coming, and antifreeze must be carefully checked. Don't think that if you have antifreeze in your car, it's all right, it's very necessary to do a freezing point test. Antifreeze can cause the freezing point to rise as time is used.

If the weather is extremely cold, the water circuit is frozen, which will cause the car water pump to fail to operate, not catch fire, and damage other engine parts.

In winter, the car has a lot of wear and tear, so the owner should maintain the car more frequently than usual. Observe your car more, find professional maintenance personnel to solve problems in time, and do not blindly replace auto parts by yourself, so as to effectively extend the service life of your car and ensure your driving safety.

If the car starter is frozen, you can splash the starter with hot water or blow the starter with a hot blower, and you can start normally after the starter heats up.

The starter is a valuable part of the car and will not be damaged easily, but in order to prolong the life of the starter, proper use is also necessary. In the process of starting the engine, the starter should introduce 300 400ah of power from the battery, so in order to prevent the battery from overcurrent or damage, the starting time should not exceed 5s; In winter, it is easy to have difficulty starting, and the starting time should not be too long for each time when starting multiple times, and there should be an appropriate interval in each start.

The starting system converts the electrical energy stored in the battery into mechanical energy, and to achieve this conversion, a starter must be used. The function of the starter is to generate power from the DC motor, and drive the engine crankshaft to rotate through the transmission mechanism, so as to realize the starting of the engine.

The starting system includes the following components: battery, ignition switch (starting switch), starter assembly, starting relay, etc.

You can pour warm water over the doorknob or on the ice in the crack of the door.

If you can't open the door after sleet, you can pour warm water over the door handle or the ice in the crack of the door to let it melt slowly. However, it is also important to wipe the water with a dry cloth immediately after the door is thawed, otherwise a thicker layer of ice may form.

Also, in this case, don't lower the rubber next to the window immediately after entering the car, as it is usually frozen with the rubber strip as well. If you force it, it may cause the window glass to break. It is recommended to cover the car after the vehicle is parked in cold areas, which can effectively avoid the situation of the door being frozen.

Maintenance of the car in winter

1. The battery should be maintained in time in winter.

Battery drain is the most common problem this season, so it's important to check the battery level. If you find that there are white oxides at the terminal of the electrodes, you should rinse them with warm boiled water, because these oxides will cause a lack of power in the motor and make the battery in a state of power loss. In severe cases, it can also lead to car breakdown and battery scrapping.

2. Replace the glass with water in time in winter.

The weather gradually gets colder after winter, and the minimum temperature in some places in the north has reached below freezing, so it is necessary to replace the antifreeze glass water in time. The glass water should also be lower than the lowest temperature in the area, otherwise the glass pot and pipes will freeze and crack.

Regardless of whether the vehicle starter can work or not, as long as the vehicle cannot be hit many times, don't continue to try to ignite, and quickly call the rescue**Ask a professional to check the problem.

Assuming that the starter can work normally, but the vehicle cannot start normally, then it means that there is a problem with other components such as the engine, if you continue to try to ignite at this time, it is easy to use up the power in the battery, and at the same time, continuous ignition is also not good for the starter.

If you find that the starter has not been able to work normally when ignition, then it is very likely that the battery has lost power at this time, and then try to ignite without smiling and cautious, it will cause damage to the battery of the vehicle, and even lead to the scrapping of the battery.

If it is confirmed that the vehicle battery is out of power, you need to find another vehicle or battery to rescue. The front of the rescue vehicle should be as close to the front of the rescued vehicle as possible, so as not to be too far away and the length of the wire is not enough.

It is best to turn off the power of the rescue vehicle during the rescue, so as not to cause a short circuit in the vehicle circuit and damage to the electronic equipment of the vehicle due to negligence by connecting the positive and negative poles of the battery.
