Why doesn t the engine catch fire in winter The battery may fail

When the weather is cold, the battery will be relatively strong.

If the car can't start, it doesn't necessarily mean that the battery is dead, and other possibilities also exist.

In fact, the current electronic control starting system is far from being as simple as in the diagram, not only the two basic components of the battery and the starter, but also various electronic components such as relays, wiring harnesses, control modules, brake pedal switches, gear sensors and start buttons.

Not only that, but faults in the engine itself can also cause the vehicle to fail to start, such as the fuel supply system, ignition system, intake and exhaust system, mechanical failure, and so on. Therefore, when we encounter the situation that the vehicle cannot be started, in fact, it cannot simply be considered that the battery or starter is broken, but these two fault phenomena are more common.

To sum up, as an "unarmed" ordinary car owner can roughly judge whether it is a starter problem or a battery problem through the sound, but the best way is to call the insurance company directly for free rescue and let the rescue master deal with it.

So for professional maintenance personnel, if you also listen to the sound like an ordinary car owner and change the battery and start the motor, then I advise you to self-reflect, whether it is a lack of ability or a bad problem of empiricism.

Car battery, also known as storage battery, is a type of battery, which works by converting chemical energy into electrical energy.

Batteries are divided into ordinary batteries, dry-charged batteries, and maintenance-free batteries. Usually, what people say about the battery refers to the lead-acid battery, and the normal service life of the car battery ranges from 1 to 8 years, which has a lot to do with the situation of the vehicle.

Hello Check the battery power, if the voltage is too low, it means that the power is lost, if the power is normal, check the battery wire, clip, contact is good. If it's normal, then consider the starter.

It may be that the battery is aging and out of power, so you can remove it and charge it yourself if you are in a hurry, if you are in a hurry to use the car, you can find a new battery for Tuhu, the ** battery adapted to the brand is available, and it is much cheaper than the 4S store!

Whether the battery is losing power should be judged by listening to the sound when it starts, not just looking at the headlights or instruments. They only require a small amount of electricity to glow, and the engine requires a lot of current, and the battery voltage is slightly insufficient to rotate.

There are three main situations of battery power loss, one is the weak start, the normal start should have a loud sound of "click", the starter rotation is obviously weak when the power is lost, the rotation is slow, and the sound will become smaller; The second is that only a "pop" sound is heard when starting, and then there is no sound; Third, if there is no sound when starting, but the instrument and headlights will be dimmed, this is a serious loss of power of the battery.

Inaccurate timing is the biggest possibility, you might as well check the timing.

Inspection method: 1. The order of each cylinder line of the fire line is wrong.

Second, the fire line is aging, and the internal contact is not good or broken after pressing it again. In this case, a new line is required. Re-tightening may also be normal.

Third, the distributor is broken.

Fourth, the low-voltage electric input line is broken.

Fifth, the spark plug is broken.

6. Spark plug oil flooding. In this case, it is possible to wait for a taxi to take a ride.

Solution: Remove a cylinder spark plug and plug the cylinder head hole with cloth or paper, and then hang the first or second gear (do not start) Release the handbrake and slowly pull the car until the cloth or paper is washed off, then it is the ignition position of a cylinder, but it is not necessarily accurate, you can look at the mark of the crankshaft belt pulley (a point or a carved line) on the cylinder block? Aligning the ignition position of a cylinder is accurate, and you are opening the distributor cover to see that the distributor head is not in the position of the ignition distribution line.

It is also possible that the battery voltage is insufficient, the voltage is insufficient, it does not mean that there is no power, the horn and the lights can also be lit, but the starter cannot be brought up. The battery light is on as long as the key is placed in the ON place before the fire is lit.

1. The battery voltage of the car is low; Specific detection method: test the battery voltage with a three-purpose meter voltage level, if it is below 10V, it is recommended to replace it. If it is around 11V, it is barely used; Be prepared for replacement. It can be used above 12V;

2. Check whether it is caused by carbon deposits; If you travel about 20,000 km, focus on checking and cleaning the throttle;

3. Inspect, test and replace spark plugs;

4. Confirm the quality of the gasoline added;

5. Detecting the ignition switch;

6. Test and detect the starter, gasoline pump, sensor and other related components of the starting and oil supply system;

7. After powering on, do not start immediately, wait for 30 seconds to 1 minute, and then ignite; See if it works;

Regardless of any of the above situations, pay attention to the time when the car cannot be hit once, be sure to play again after an interval of 15-30 seconds to protect the battery but not generate power and prolong its service life.

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.

Hello! 1.The starter motor malfunctioned and could not drive the flywheel to turn.

Check if the starter motor is working when starting the vehicle. 2.The ignition system of the vehicle failed.

Unplug the ignition high-voltage line on the engine, insert the old spark plug or other pen-shaped metal rod into the spark plug cap, put the spark plug body or metal rod body close to the metal part of the engine, start the engine to observe whether there is a high-voltage flashover, and check the ignition system if not. 3.The vehicle's fuel supply system failed.

Unplug the oil pipe joint on the engine, turn on the ignition switch, and observe whether there is oil flowing out when the instrument light is on (the starter is not running). If there is oil outflow, there is no problem with the oil supply system, and if there is no oil, continue to check. Hope it helps.

1. It may be that the service life of the battery is up, and the battery cannot store power inside, so the vehicle can not be started because there is no answer to drive the starting motor to work, so the vehicle cannot be started, it is recommended to check the health of the battery, and it needs to be replaced if it is less than 10%.

2. It may be that there is a fault in the starting motor, resulting in the gear of the starting motor cannot drive the flywheel to rotate, so the vehicle cannot start.

3. Check whether the ignition system and fuel injection system of the vehicle are working normally, if the spark plug does not ignite or the fuel injector does not inject fuel when the vehicle starts. It can also cause the vehicle to fail to start.

4. If you check the battery, starting motor, ignition system, and fuel system of the vehicle, they are all normal. At this time, it is necessary to check whether the vehicle has a leakage fault, resulting in the vehicle being parked for a few days, and the power inside the battery is leaking. So it can't start.

Question: I opened it last night, I put it on for one night, and now I can't make it, and I just can't make a sound.

Question: Now I'm going to look for a car repairer.

Hello, the working conditions of any engine are fuel pressure, ignition strength, cylinder pressure, timing normal, and starter voltage. This is the engine hardware necessary, you mentioned that the problem is very extensive, can not give you a specific analysis, repair a car need to know the fault car of which year of the model, displacement, kilometers, vehicle configuration, and other information can be comprehensively analyzed. If you are satisfied, please accept, thank you.

Then it may also be that the power of your battery is insufficient, but there is electricity, but it can't ignite, which is a bit insufficient power, so hurry up to charge it and put the power sufficiently. Love will do it.

There are many reasons for this, and what is it like to start with this non-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.

In winter, the car battery often does not ignite, because the weather is too cold, the lighter equipment is faulty, so it is best to recommend that you can communicate with professionals to replace the lighter with good quality, so that the use will be fundamentally determined.

Therefore, when learning to communicate with professionals, you must master the correct learning methods, and the specific steps are as follows.

1) Be good at learning the strengths of others.

As the saying goes, "The ruler is short, but the inch is long." "No matter how smart a person is, there are shortcomings, no one is perfect, and as the 21st century, we should be more aware of this, only learn from the advantages of others, for their own use of the person is the real wisdom, the real person can achieve great things.

Many people's success is based on their own ability to learn from others. When we were in school, our teachers often told us about role models, in fact, it is the same nature, only by looking at the advantages of others and learning from the advantages of others, can we have advantages, avoid detours, and succeed as soon as possible.

2) Be good at learning from other people's words.

We learn from others, not only to be good at learning the advantages of others, but also to learn from the words of others, the power of language is huge, often one or two sentences from others to express your shortcomings, promote your heart to learn and struggle.

3) Be good at learning from other people's criticism.

As a modern high-performance talent, it is not only required to be able to learn from the advantages of others and the words of others, but also from the criticism of others.

Criticism is actually a kind of speech, but it should be more valued by us and more conducive to our learning.

Those who criticize us, no matter how bad their motives, should not have a bad mentality. Most of the criticisms of others are right.

But some people think that no matter whether they are right or wrong, they must always try to defend themselves, so they gradually develop a concept that they always think they are right. "Hard-headed people are always those who are simple-minded and have limited intelligence".

Improve yourself from the advantages and criticisms of others, use the advantages of others for your own use, and keep yourself for yourself, and you will continue to improve yourself and perfect yourself; When others criticize you, accept it and use it as a guide for you to move forward, not as a remark for your failure.
