What are the reasons why the car does not catch fire and how to repair it?

First, there is the issue of oil products. When we used to repair the car, we found that there was water and mud in the fuel tank after disassembling it, and with such oil, it was impossible for the car not to break. Therefore, remind the owner to be sure to go to the regular gas station to refuel, and you can bring a gauze wrapped in the muzzle of the refueling gun to filter impurities.

Second, no antifreeze is added. Some car owners add water or inferior antifreeze to the car, resulting in a particularly cold winter, causing the entire waterway to be frozen, the engine to be frozen and cracked, resulting in the car water pump can not operate, can not catch fire, and injure other parts of the engine.

Too much carbon in the vehicle will also cause the vehicle to not catch fire, and the solution is to run at high speeds to reduce the carbon deposit. In addition, there is a small trick for not ignition, before starting the ignition, first screw the key to the ON switch, and then turn it back, and then turn on the strat switch to ignition, let the computer run to calculate the water temperature and the appropriate air intake, and the ignition will be smoother.

Common reasons why the car won't ignite:

1. The battery power loss cannot provide the required working current to the starter, and the fault phenomenon is that the starter sound is weak;

2. If the starter fails to ignite, if the battery has power, the starter sound cannot be heard during ignition, which means that the starter is faulty;

3. If there is a problem with the oil supply system, to eliminate the first two problems, it is necessary to consider the failure of the oil supply system, and mainly check whether the oil pump is working normally.

Car starting conditions: oil (normal oil supply system), fire (high-voltage coil and spark plug work normally), timing (normal supply and exhaust system), car can not ignite, check and deal with the above conditions.

There are many reasons why you can't get a car, but the common ones are: battery problems, poor circuits, poor fuel mixing ratio, fuel does not liquefy due to low temperature, oil freezes due to low temperature, and the throttle is seriously dirty.

Reasons and solutions for the car not catching fire: 1. If the battery is out of power, the battery is out of power due to the long-term headlights are not turned off, etc., or the battery life expires, charge or replace the battery in time; 2. The fuel tank is empty, and the fuel gauge shows that it is below the red line, check the fuel gauge and refuel in time; 3. The gear is not right, the gear should be placed on the P or N gear when the automatic transmission car starts, if it is placed on the R gear or D gear, it will not ignite, and the gear can be adjusted; 4. If you have an oil problem, you must go to a regular gas station to refuel, and you can bring a gauze wrapped in the muzzle of the refueling gun to filter impurities;

There are many influencing factors:

1. The battery has electricity but the voltage is low, and it will be difficult to start below, 2. The motor is broken, or the belt drive is problematic, 3. There is a problem with the circuit, 4. The oil circuit is a problem, 5. The problem of the high-voltage generator, 6. The throttle problem of the car, 7. The spark plug problem, etc.

1.Check the status of the battery In most cases, the difficulty of starting the car in winter is caused by the loss of battery power or the expiration of the battery life. When the battery is low, the speed is weak when starting the car, and only the clicking sound is heard, and the clicking sound will gradually become a clicking sound when the ignition is lit again.

Do not ignite continuously to avoid the battery running out.

2.Change the right oil In winter, as the temperature drops, the viscosity of the oil increases, making it difficult for the oil to flow, which increases the resistance of the engine. If starting is difficult, check if the oil is used.

3.Replace the spark plug in time After a few years of use, the spark plug is easy to cause problems such as carbon deposit, leakage, excessive gap, and ablation, which will cause the car.

There are many influencing factors:

1. The battery has electricity but the voltage is low, and it will be difficult to start below, 2. The starter is broken, or the belt drive is problematic, 3. There is a problem with the circuit, 4. The oil circuit is a problem, 5. The ignition coil is a problem, 6. The throttle problem of the car, 7. The spark plug problem, the crankshaft position sensor, etc.

Generally, the car does not catch fire, it is generally caused by the battery, insufficient voltage or spark plug failure.

1. Take the wire: This is a necessary item for the car to take the electricity, do not take two wires to make do, because the instantaneous current of the vehicle at the start can reach 200-600A, and the diesel car even reaches 1000A, if it is calculated, 10 square copper wires can ensure the smooth and safe start, so the car battery connection line must buy the right brand, the quality is the best, do not try to be cheap. This is one of the must-have items in the car, once the battery is out of power, you can take it out and use it, and you can also help others when you don't use it.

2. Emergency power supply: This is a new type of power bank like a thing, there are two kinds of lead-acid and polymer lithium battery, which can help the vehicle with a loss of power to start, and can also have lighting, charging mobile phones and multi-functional supplies used with an inflatable pump to inflate the car. And it is generally portable, very lightweight, if you have it, you don't have to ask others for help.

Be sure to charge it in time after use and keep it full of power to deal with emergencies.

3. Positive, first connect the positive: first turn off all the electrical equipment on the car, make the key in the OFF position, open the cabin cover to find the battery, there are positive and negative poles written on the battery, generally the red "+" sign is the positive pole, and there are generally two wires, at this time, take out the red one, open the battery cover, pinch the clamp on the head to clamp firmly the positive pole of the battery of the electric car, and the clamp at the other end to clamp the positive pole of the battery of the rescue vehicle. Be sure to connect the positive electrode first, then the negative electrode, do not reverse the order, and do not use the battery clamp to touch anywhere except the battery pile head.

4. Negative connection, negative connection: After the red positive electrode is connected, take out another wire, first clamp the negative pole of the tram battery, the negative electrode is generally black "—" number, and then pinch the other end of the clip, from beginning to end the clip do not touch other places, to clamp the negative pole of the rescue vehicle battery, when the connection will pop out of the electric spark, please don't be afraid, this also shows that you are right. The reason why the negative electrode is not connected first is because the whole vehicle is basically a negative electrode (that is, commonly known as "tie iron"), if the negative electrode is connected first, when connecting the positive electrode, the clip will cause a short circuit and burn the parts on the car when it touches any conductive place in the body.

5. After starting the vehicle, first remove the negative, and then dismantle the positive: after the battery is connected, the rescue vehicle will first ignite and charge the battery, and then the no tram enters the vehicle to open the key, at this time the instrument light will be lit smoothly, and then try to ignite (not more than 5 seconds), if it fails to start smoothly, step on the accelerator of the rescue vehicle, and the speed is kept at about 2500 rpm, and then the tram is ignited again, if the starter is no problem, the car has oil in the case of general can be started smoothly, after the non-electric vehicle starts, Remove the negative clamp first, then remove the positive clamp, for the same reason as why the negative pole is followed by the fourth one.

The positive and negative poles of the battery must not be reversed, and the order of assembly and disassembly should be strictly in accordance with the order of first connecting the positive and then the negative, and the first dismantling and then the positive.

After having a car, the most depressing thing is that when you are in a hurry to use the car, it suddenly can't catch fire, yesterday was fine, why can't it be started today? Many car owners are very puzzled, what is the problem? What should I do in such a situation?

Today, I will talk to you about the more common emergency treatment methods that can judge the cause by yourself.

1. The steering wheel is locked.

When the owner does not turn the steering wheel back to the right after parking and turning off the ignition, it is easy to lock the steering wheel, this function is mainly for anti-theft considerations, and the result is that the key can not be screwed and cannot be ignited. The solution is that as long as you twist the key while playing the steering wheel, you can usually unlock the steering wheel quickly!

Second, the fuel is insufficient.

Generally, this situation mainly appears in the process of driving, if the engine suddenly turns off during driving, you should look at the fuel gauge as soon as possible, confirm whether the fuel tank has no oil, at this time as long as you refuel the car. At the same time, while driving, the owner should check the fuel tank fuel level in time, and when approaching the warning position, he should refuel in time.

3. The battery loses power.

If the battery problem does not ignite, it is generally due to these reasons: the battery reaches its service life, the circuit fails, or the battery loses power due to forgetting to turn off the lights. The method of judging whether the vehicle battery has electricity is also relatively simple, press the horn, if the horn can sound, it proves that the battery is electrified, and it may be caused by other reasons that it cannot be started.

If the battery is unable to start due to power loss, you can call the rescue** or find another car to help dock and start. Car batteries are consumables, and it is recommended to replace them every 2-3 years.

Fourth, the motor is faulty or the fuel filter is blocked.

In addition to the above reasons for human operation, it is also possible that the motor failure or fuel filter blockage caused by insufficient oil supply, in such a complex situation, it is necessary to ask professionals to overhaul.

To sum it up in the end:

There are many reasons why the vehicle can not be started, in addition to the common ones that can be dealt with by themselves, such as poor anti-theft, line failure, computer failure, engine carbon deposit, etc., these problems need to be repaired at a professional maintenance point. In addition, there is also a little trick when ignition, before ignition, first screw the key to the ON switch, and then turn it back, and then turn it on to start ignition, let the computer run to calculate the water temperature and the appropriate air intake, which will help to start more smoothly!

The reason why the car does not catch fire is caused by improper operation, such as no fuel, no electricity, wrong gear, and these situations are quite common, observe the fuel tank situation in time, and the dashboard prompts that the fuel volume is insufficient, and refuel nearby; If the car battery is out of power, you can use someone else's car to connect the battery to ignite; Operate the gears correctly in accordance with the car instructions.

What should I do if the car does not catch fire?

In addition to the reasons for improper human operation, there may also be motor failure, or oil pump oil supply, fuel injector problems, sensor failure, etc., encountering these more complex situations, need to be dealt with by professionals. However, pay more attention to the following items when using a car to avoid these complex situations.

Reasons why the car won't catch fire:

1. If there is no oil, the oil gauge shows that it is below the red line, so it will naturally not catch fire;

2. If the battery is out of power, it may be due to the loss of power caused by the long-term headlights not turned off or the battery life expires, and it is generally recommended to replace the battery in time after 2 yearsIn addition, the installation of xenon headlights, high-power audio, etc. is also the cause of vehicle circuit failure;

3. The gear is wrong, the gear must be placed on the P or N gear when the automatic transmission car starts, and if it is placed on the R or D gear, it will not ignite.

There may be several reasons why the car cannot ignite, and the steering wheel is in a locked state: when the steering wheel is not corrected when parking, it is easy to have the steering wheel locked, resulting in the key being inserted and not being able to screw it, and the car can not be lit. 2

The battery of the car has a power loss: the battery of the car is also a consumable, and it is recommended to replace the battery once in 2-3 years. If the battery is out of power and cannot ignite, you can take the method of taking electricity, first of all, the front of the two cars "face to face" (the two cars can be as close to each other as possible), and then turn off the rescue vehicle, so as not to burn the battery line due to excessive current, the electrical switches of the rescue vehicle are turned off, open the engine compartment of both sides (some car batteries are placed in the rear trunk, such as BMW), and find the positive and negative poles of the batteries on both sides (with red "+" for the positive pole and black "-" for the negative pole).

Remember the positive and negative poles of the vehicle, don't make the wrong connection.

Next, how to correctly connect the wire is: first connect the positive end of the battery of the loss-stricken vehicle with the positive and extreme connection of the battery of the rescue vehicle;Then connect the negative terminal of the rescue vehicle battery to the wire and then connect it with the iron sheet of the body of the vehicle with a loss of power (try not to connect the negative electrode, it is easy to produce sparks, and the battery will be damaged in serious cases.

Black is the negative wire, and red is the positive wire.

After making sure that the wires are connected correctly and that the contact is good, start the rescue vehicle;Let it run for a few minutes before charging the vehicle with a loss of power. Then start the loss-free vehicle.

If the power loss vehicle can not start, this is to give the throttle of the rescue vehicle to some oil, and then start the power loss vehicle, remember not to start forcibly, pay attention to the starting interval, if it can not start, it is necessary to consider whether the wire is too thin, the current caused is not enough.

Remember the positive and negative pole markings on the battery.

When the vehicle is started, the battery clamp can be removed at this time, and the order of taking power should be:

1. First remove the negative pole of the rescued vehicle with the iron wire, and then remove the negative wire of the rescue vehicle;

2. Furthermore, remove the positive wire of the rescue vehicle, and then remove the positive wire of the rescued vehicle.

Remember the order of unplugging 4 4

If the motor fails, or the fuel filter surface is clogged and the car doesn't start, it's time to ask a professional to solve it.

1. There is no response when the vehicle starts, so in this case, you first need to check whether it is caused by the battery power loss? If the battery is out of power, you need to charge the battery or replace it with a new one.

In the case of making sure that the battery does not lose power, focus on checking whether there is a problem with the vehicle starter or whether the anti-theft is locked? If there is a problem with the starter, you need to check the corresponding control circuit of the starter or replace the starter. If there is a problem with the anti-theft system, you need to re-do the anti-theft matching.

2. The vehicle engine can rotate, but it does not catch fire, so in this case, it is important to check whether the oil pressure of the gasoline pump is insufficient? Or the vehicle engine does not ignite, if the pump oil pressure is insufficient, this situation requires the gasoline pump to be replaced. Check the fuse or wiring of the gasoline pump.
