Everything in the car is normal, but it doesn t catch fire, what s going on

The engine does not catch fire and is one of the most common faults in cars.

There are two situations when it can't catch fire:

One is that the BAI rotation of the starter can be heard, but the engine cannot start. The other is that after twisting the key, there is no sound.

Reasons: 1. The battery loses power.

When the car battery loses power, the car will not be able to hit the car, and there are many reasons for the loss of car battery, such as the lack of water in the battery, or the battery is faulty, and the use of air conditioning for too long will cause the car battery to lose power. When the car can't be driven, first check whether there is a problem with the car battery, what kind of problem it is, and then send it to the 4S shop for maintenance.

2. The temperature is too low.

In winter, the weather is cold, and the car often fails to drive. This is because in a low temperature environment, the viscosity speed of the automobile oil decreases, which leads to a decrease in the ignition energy of the battery and a decrease in molecular activity, so that flammable gases cannot be formed, and it is difficult to get on the car.

If this happens, don't panic, it's not a car breakdown, it's a normal phenomenon, you can try to step on the clutch first and then ignite, maybe it will be better to get on the car.

3. Carbon deposition in automobiles.

Car engines.

Carbon deposits can lead to a number of problems, the most common of which is that the car is not working well. There are many reasons for engine carbon deposits, such as a lot of moisture in gasoline, poor fuel variety, poor valve seat sealing, and so on. Therefore, if the car is not good, you may wish to see if the car engine has a lot of carbon deposits, and if so, clean it up in time.

Extended Information: How to maintain your car:

1. Spark plugs.

of the inspection. Normal spark plug insulating ceramics are intact. There is no rupture leakage, and the spark is blue and strong. If an abnormality is found, the gap should be adjusted or the spark plug replaced.

Check the gasoline filter, if the oil supply is not smooth, check whether the gasoline filter is blocked, if the foreign body is blocked, it should be replaced in time.

2. Maintenance and inspection of batteries.

Check that the battery is firmly fixed with the electrolyte.

It should be between the upper and lower limits, and the electrolyte or distilled water should be added in time when it is close to the end of the line.

Highest line. Keep the positive and negative cables of the battery in good contact, and keep the battery clean and dry.

Vehicles that have been placed for a long time should take off the positive and negative cables of the battery, rewire and start the engine about 20 minutes after about half a month, and charge it in time if the power is obviously insufficient.

3. Engine coolant.

Liquid level inspection. Never open the radiator cover when the engine is in a hot state, otherwise you may be scalded by splashed coolant or hot vapors.

After the engine is cooled, check that the liquid level of the coolant should be between full and low, otherwise distilled water or pure water (mineral water cannot be added) or refrigerant should be added, and the liquid level height after adding water should not exceed the full level.

If you find that the coolant is reduced quickly in a short period of time, you should check the cooling system for leaks or go to the repair station to check.

Since everything is normal, it can only change the car, it is recommended to check it well, carefully inspect it from the aspects of oil, electricity, gas, timing, and anti-theft, and you will definitely find the fault, and you will not die if you are not sick.

The ignition itself is a very serious problem, it is abnormal, so it is impossible for your car to be normal, and it is a more complicated situation to ignition, it may be the circuit of the car, the battery, the circuit, the ignition coil, the spark plug, the oil circuit, and even the quality of the oil is likely to affect the ignition, and you need to go to a professional repair shop for inspection.

The car can't catch fire normally, see if there is a problem with the battery, if the battery doesn't work, it won't catch fire, you can replace the battery.

If the car does not catch fire, it may be that the flow of gasoline is blocked. 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.

In addition to the reasons for improper human operation, improper oil products, no antifreeze, and excessive carbon deposits, there may also be motor failures, or oil pump oil supply, fuel injector problems, sensor failures, etc., which need to be dealt with by professionals. However, pay more attention to the following items when using a car to avoid these complex situations.

The car suddenly does not catch fire, it may be that the battery is not good, the battery is generally used for about four years, and if it is maintained and used well, it is also useful for six or seven years. In addition to the reasons for improper human operation, there may also be motor failure, oil pump supply, fuel injector problem, sensor failure, etc., which need to be dealt with by professionals.

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 appropriate engine 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 it is difficult to start, check whether the oil label is incorrect.

3. Replace the spark plug in time.

After a few years of use, spark plugs are prone to cause problems such as carbon deposition, leakage, excessive clearance, and ablation, which will cause difficulties in car ignition, cold start, and even hot engine start, and often need to be ignited multiple times. Therefore, when driving to a certain number of kilometers or feeling that the vehicle is difficult to start, weak, shaking, increasing fuel consumption, or inexplicably stalling, please check the spark plug status and replace it in time.

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.

Turn on the key and wait for the computer to finish the self-test before ignition, because the gasoline pump starts to pump oil to the nozzle during the self-test! The engine oil should be changed, and the spark plug should be checked once every 10,000 kilometers. It is recommended to replace the spark plug, and the original spark plug is 16 pieces!!

It is very likely that the battery is fed, and you can call the rescue** to flush down your battery.

1. The temperature is too low

This situation generally appears in winter, because in such an environment the viscosity and speed of the car oil are reduced, but the ignition energy of the battery is reduced, so that the flammable gas can not be formed, and it is difficult to ignite.

2. Spark plugs

The spark plug is a key component in the automobile ignition system, and the ignition system of the vehicle is the key to the work of the car's heart, so whether the spark plug can work normally is related to the working performance and efficiency of the vehicle.

Emergency method: You can unscrew out the spark plug and wipe it clean, and you can start the car after installation. The thorough approach is to check the ignition system and rule out the causes of low ignition energy, such as spark plug electrode gaps, ignition coil energy, high-voltage line status, etc.

3. Insufficient oil quantity

In this case, as long as you refuel your car, it will be able to disappear. Therefore, in the process of ordinary driving, the driver should also check the amount of fuel in the mailbox in time, and when it is close to the warning position, it is necessary to add fuel to his vehicle in time.

4. The battery has a power loss

The battery loss will be able to feel that the starter is boring when ignition, a little bit can't move the engine, two consecutive fires, then the first time will be greater than the back of the force, the more it can't catch fire, the more boring.

5. The gear is wrong

However, the gear is not right, this situation is generally only committed by novices, and the general automatic transmission model can only be started when it is hung to the P gear, and if it is placed on the R or D gear, it will not ignite. There are also some manual transmission cars that will not catch fire if you don't step on the clutch. And many car owners hang the gear in N gear and turn off the engine when they are temporarily parked.

There are many times in life that the car does not catch fire, what is the reason, the rabbit takes you to understand the reason, generally the car does not catch fire and do not need to worry, sometimes it may be a problem during operation, the most common is that the steering wheel is locked.

If the car won't ignite, don't worry, because it's probably not a big problem, but just some problems with the operation.

One of the most common reasons is that the steering wheel of the car is locked, and if you do not pay attention when the vehicle is turned off, the steering wheel may be locked in a locked state, and the ignition operation cannot be carried out at this time. At this time, as long as you use a physical method, you can unlock the steering wheel, and the specific operation is to quickly shake the keyhole, and basically it can be restored to normal in about 10 seconds.

Of course, it is possible that the oil supply pipeline is blocked, resulting in the oil not being able to burn enough and supply it to the engine, resulting in low engine efficiency and eventually making the car unable to ignite.

If it is for this reason, it is best not to repair or touch the relevant parts and facilities without authorization, but to drive the car to the relevant repair shop for pipeline dredging, and have professional staff to deal with it, so as to ensure the safety of driving.

Of course, there are some other more common reasons, such as insufficient fuel, insufficient battery power, etc., most of which are caused by not paying too much attention to the condition of the car in daily life, and do not need to be too nervous.

The car can not catch fire is still a very common problem, since the repair shop has helped you to see or can not find the problem, you can see if it is because of the car these reasons, that is, the electric oil and gas, so you may wish to check one by one according to the three of them.

You've checked the oil, three filters or something, but have you ever checked the car's battery?

The life of the battery is only about two or three years, is it that your battery life is almost up but has not been completely damaged, so the fire sometimes hits and sometimes can't.

In addition, there may be a battery power loss, and sometimes it can be ignited and sometimes it can't, and you have seen those throttles, so you should check whether there is a problem with the battery.

There is also whether the fuel tank is out of oil, if the fuel tank is not refueled in time, you want it to be hungry how to work for you, so you also need to look at the fuel tank in time to refuel, maybe the maintenance day just happened to be full of fuel so the maintenance workers can not see a reason.

There is also a small problem that is easy to be ignored is whether your key is out of power, if your car belongs to what kind of car with the key can be started with a key button, then you can see if the key is out of power, the key is almost out of power and then this situation will occur, the most direct way to judge is to use the mechanical key to drive, if the mechanical key to drive everything is normal, it must be the problem of the key, if it is not this kind of car then this problem can naturally be ignored.

In addition, the fuel system is clogged, and you can clean the oil circuit before driving.
