What to do if the car does not catch fire? What should I do if my car won t catch fire?

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.

What is the reason why the car does not catch fire?

1. Check the battery level.

The biggest possibility that the car does not catch fire is that the battery is insufficient, at this time, turn the key only to hear the sound of the clang, you can try to refuel the car and then ignition, if it really doesn't work, you can only replace the battery or charge the battery in time.

2. Check whether the flow of oil is blocked.

If you are driving in winter, the viscosity of the oil will increase, and it will be difficult to flow, which will increase the resistance of the engine of our vehicle.

3. Check whether the spark plug is faulty.

If the spark plug is not replaced in time, the vehicle will have a sense of frustration, and there will be shaking when idling, we can disassemble the car body to check the spark plug to see if there is any air leakage, if there is, to replace it in time.

4. Check whether the exhaust pipe is frozen.

If it is an electronic throttle, it is easy to accumulate carbon, and the water vapor produced by the engine operation will freeze. Therefore, we must run more long distances to prevent carbon accumulation, and we can also drain the stagnant water in the exhaust pipe.

5. Check the condition of antifreeze.

If it is a cold winter, we must not add some good antifreeze to the car, do not add water or bad antifreeze, otherwise it is easy to freeze the entire waterway, if it is serious, it may also freeze the engine, so that the car can not catch fire.

6. Check whether the motor is faulty.

If it is a car oil pump problem, it will make the gasoline pressure insufficient, and there will be a situation that it cannot ignite, and motor failure and gasoline grid blockage will lead to a situation that cannot ignite, so be sure to clean the oil circuit in time and replace the gasoline grid.

7. Check whether the parking position is a problem.

If the vehicle is parked in low temperature conditions, if the engine is started at this time, it will be relatively difficult, the engine will wear out quickly, and the service life will be affected, so if it is not parked properly, it will also lead to no fire, it is recommended to choose some flat and warm places to park.

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, 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 wiring method is: first connect the positive end of the battery of the loss-stricken vehicle with the positive end of the rescue vehicle battery; Then connect the negative pole of the rescue vehicle battery to the wire and then connect it with the iron sheet of the body of the vehicle with power loss (try not to connect the negative electrode, it is easy to produce sparks, and it will cause damage to the battery 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 loss of power vehicle can not start, this is to give the throttle of the rescue vehicle to some oil, and then to start the loss of power vehicle, remember not to force the start, pay attention to the start of the 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 pole 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.

Hello, I'll send you a few ways to refer to it.

1) Power off and restart: The car is also like a mobile phone, shutting down and restarting can solve a lot of problems! If the car is not on fire, you can also try powering it off and restarting it.

When you find that it is not playing, open the front cover of the car and find the battery. Generally speaking, the positive and negative poles of the battery have a buckle that can be broken by hand without tools. After breaking it open, the whole car will be powered off, and after a minute of installation, it is equivalent to a restart.

Try again at this point. If it still can't ignite, the battery may be dead. There are many reasons why the battery is dead, it could be that you haven't driven for a long time, or you forgot to turn off your car's headlights and some electrical equipment.

2) Ride-up: What is ride-up? Simply put, connect your car's battery to an external power source.

At present, there is a product called car power bank, which sells very well on the Internet. Generally** is about 200 yuan. This power bank can charge not only mobile phones, but also cars and even laptops, as it has an additional 12V output port.

3) Replace the battery: The battery is a vulnerable part of the car, and the lifespan is only 3 to 4 years. Even if there is no problem, it should be replaced when it expires.

Replacing the battery at a 4S shop is certainly safe, but the cost is a bit high! Roadside car repair shops can also be replaced, which are usually cheaper, and the car battery is only 500-600 yuan. Here's a cheap and quick way to do it!

Find a reputable seller and report your model to the buyer. Generally speaking, the real battery only costs 300 or 400 yuan, and then install it yourself or ask the master to install it.

1. Cause analysis:

Many of the reasons why you can't ignite are caused by improper operation, such as running out of oil, running out of electricity, and having the wrong gear, and these situations are quite common.

1.Out of gas. I went out to rescue a car before, but the fuel gauge showed that it was below the red line, so naturally it could not catch fire.

2.The battery is dead. It may be due to the loss of power caused by the headlights not turned off for a long time or the battery life expires, and it is generally recommended to replace the battery in time after three years.

In addition, the installation of xenon headlights, high-power audio, etc. are also the causes of vehicle circuit failures. The situation of the vehicle without power is easy to check, just press the horn to know.

3.The gear is wrong. When the automatic transmission car starts, the gear must be placed on the P or N gear, 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.

Second, what to do and how to solve the reason why the car cannot catch fire.

Reasons for vehicle use: improper oil, no antifreeze, excessive carbon deposit.

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.

1. Oil problem. When I was repairing a car, I found that there was water and mud in the fuel tank after dismantling it, and it was impossible to use such oil to keep the car from breaking. Therefore, it is reminded that you must go to a regular gas station to refuel, and you can bring a gauze wrapped in the muzzle of the gas gun to filter impurities.

2. No antifreeze 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.

3. Too much carbon accumulation in the vehicle will also cause the vehicle to not catch fire, and the solution is to reduce the carbon deposit by running at high speed frequently. 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.

1. At low temperature, the battery reduces the output power due to the increase of electrolyte viscosity, the decrease of permeability, and the increase of resistance, which makes it difficult for the starter to drag the engine, and cannot reach the minimum starting speed, which affects the engine start. If the engine does not rotate or the speed is very slow when the car is ignited, it is very likely that the battery is dead or malfunctioning. You should find a battery with electricity and connect it to the car and try to light it.

2. Due to the low voltage of the battery terminal caused by low temperature, the spark of the spark plug is weak, and the density of the mixture increases the resistance between the electrodes, which makes it difficult to ignite the mixture and make it difficult to start the engine. At this time, check the spark plug to see if it is aging or heavy carbon deposits, and replace it with a new one if necessary.

3. Some old vehicles, oil pipes and other serious aging, the vehicle can not keep up with the oil when starting, often resulting in no ignition, so when igniting, you should step on the accelerator a little to make the gasoline cycle faster, so that it is easier to play.

4. Fill fuel in time. Some vehicles have inaccurate fuel gauge pointers, and when the fuel gauge is red light, fuel should be added in time. Otherwise, it will be difficult for the vehicle to catch fire if it can't keep up with the oil, especially in winter, when the temperature is very low.

5 If it is a diesel car, the situation of not catching fire in winter is more serious, the main solution is to replace the diesel in advance, especially the old diesel car, when the ambient temperature is about 0 degrees, it is recommended to replace the diesel of minus 10; When the ambient temperature is below minus 5 degrees, it should be replaced with minus 20; When the ambient temperature is lower, replace it with a diesel fuel of minus 30.

tips when starting your car in winter.

1. In winter, after starting the engine, turn on the lights, radio and other electrical equipment. Before stopping, turn off these power-hungry appliances and then turn off the engine.

2. When the car cannot be started for the first time, do not ...... the second and third consecutive lighters, which will only accelerate the consumption of electrical energy. And once the electricity is consumed, even the cart will not help. Therefore, if it fails to boot the first time, it is best to wait 30 seconds before making a second boot attempt.

Also, don't rush to drive at high speed after the car starts, give the vehicle a warm-up time, so that the vehicle is not easy to wear and tear and can improve fuel economy. Generally, when the water temperature wants to rise, refuel and drive quickly.
