What s the matter that the battery can t catch fire when it has electricity

It may be 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.

There are many reasons why a car engine won't catch fire, there is a problem with the ignition system, and the spark plug doesn't ignite. There is a problem with the fuel supply system, the oil pump is not working, and the fuel is not supplied. Injectors do not inject fuel.

Insufficient cylinder pressure. Other causes include misaligned timing, camshaft, crankshaft position sensor signals that can cause the engine to not catch fire.

A car battery, also known as a battery, is a type of battery, and its working principle is to convert chemical energy into electrical energy. Usually, people refer to batteries as lead-acid batteries. That is, a battery mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution.

This may be the reason for the starter or spark plug, etc., it may be the oil pipeline, etc., or go to check.

Generally speaking, the car is likely to be out of battery, but there is still electricity after the battery is checked, so what is the reason why the car does not catch fire?

First of all, we should first check whether the fuel is insufficient, when the car has no power ** "gasoline", it will naturally not catch fire. If it is caused by no fuel, then this situation is easy to solve, you can choose to ask for help from the surrounding car owners first, apply for emergency measures such as borrowing fuel or towing to the gas station according to your own conditions.

If the car does not ignite due to insufficient fuel, then it is recommended that the owner should pay attention to the fuel gauge from time to time during driving, and when approaching the warning position, go to refuel in time, and do not wait for the fuel tank to bottom out before refueling. This is not good for the engine and is easy to shorten its service life.

In addition, the wrong gear of the car may also cause the car to not ignite. In general, P or N is the correct gear when the automatic transmission is started. If the owner is careless and puts the gear in R gear or other gears, the result will not only be unable to ignite, but also cause potential safety hazards.

At this time, it is necessary to carefully check whether the gear is correct, and once you find that the gear is wrong, you should adjust it in time. When the gears are adjusted correctly, try to start the car again.

If the above situations are excluded, the fuel is sufficient, and there is electricity, then there are many reasons why the car cannot ignite, and it may be caused by one of the many faults.

1) Electrical or electronic faults.

If this is the case, then there must be no warning before the car does not catch fire, very suddenly. Faults of circuits:FusesBurnout, high-voltage coil break, low-voltage circuit break, center ignition wire falling off, flame splitter leakage, spark plug damage.

Electronic failure mainly refers to the loss of function of the computer control board.

2) Oil circuit failure.

Oil circuit failures may occur in the following areas: oil pump failure, oil circuit failure, oil filter blockage, spark plug carbon deposit, fuel injector damage, etc.

Here's why:

1. Low temperature.

In a low-temperature environment, the capacitance of the battery will be much lower than that at room temperature, and even after a certain number of years of battery use, it is easy to have low power when parking overnight or for a long time in ice and snow weather, resulting in the vehicle not catching fire.

2. Rapid and repeated ignition.

When starting the car, the time of each start should not exceed 5 seconds, and the interval between starting again should not be less than 15 seconds, otherwise the uninterrupted use of the starter will lead to excessive discharge of the battery and damage.

Maintenance of the battery:

1. Scrub the outside of the battery with a damp cloth, and wipe the dust, oil, white powder and other dirt that is easy to cause leakage on the panel and on the pile head (that is, the positive and negative poles). In this way, the battery will be scrubbed frequently, and the pile head of the battery will not accumulate white etching powder, and its service life will be relatively long.

2. Open the battery and water cap to see if the water level is in the normal position. Generally, there will be upper and lower limit markings on the side of the battery for your reference. If you find that the water level is below the lower mark, you must add distilled water, if you can't get distilled water at once, you can use filtered tap water for emergency.

Don't add too much water, the standard is to add it to the middle of the upper and lower reticles.

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 easy to cause problems such as carbon deposition, leakage, excessive gap, 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.

The first point is likely to be the leakage phenomenon in the battery, the second point is likely to be broken, the battery can not generate electricity, and the third point is likely to be used for too long to be scrapped.

It could be because your gasoline pump has a problem and is malfunctioning. It may also be because you are in the wrong gear, so you can't catch fire all the time.

Because the car is in condition, the car is broken, and the car needs to be repaired in time before it can be opened.

1. Check the circuit to see whether the spark plug is ignited normally, whether there is leakage, whether there is a high-voltage fire in the high-voltage line, and whether there is a problem with the ignition coil of the ignition coil.

2. Check the oil circuit, open the oil pipe under the engine, open the key to ignition, whether there is oil out, if it does not come out, it may be that the oil circuit is blocked, and the fire is that the electronic oil pump is not working. There is also a general situation that does not happen, that is, the computer board is locked and started to prevent theft.

3. If there is a problem with the starter or the line connection, the car will not catch fire, and the starting voltage of the battery will be lower than that will also cause the car to not catch fire.

4. It is a problem caused by the battery running out of power, and the battery may be broken. Pulls down the system voltage.

How the engine ignition system works:

When the engine is working, the ECU determines the optimal ignition advance angle and power-on time according to the relevant programs and data stored in the memory according to the received sensor signals, and sends instructions to the igniter.

The igniter controls the turn-on and cut-off of the primary circuit of the ignition coil according to the command. When the circuit is turned on, an electric current passes through the primary circuit in the ignition coil, which stores the ignition energy in the form of a magnetic field. When the primary circuit is cut, a high induced electromotive force (15 20kV) is generated in the secondary coil, which is sent either through the distributor or directly to the spark plug of the working cylinder.

There are many reasons why you can't catch fire. One of them is battery aging. Although there is electricity, it cannot provide the large amount of current required for starting. In this case, the only way to do this is to replace the battery.

I am glad to answer for you: the common fault points of the vehicle can not start: 1. It may be that the service life of the battery has arrived, 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 can not start, 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.

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

Have you tested all the above on your side?

Questions. No, I'm going to look for a car repairer now. Okay.

Starter problems, ablation of starting relays or pick-up switches, common problems. Disassemble it and make a contact with the copper sheet. Or go with a warranty.

The amount of fuel is insufficient, and when the car has no power ** "gasoline", it will naturally not catch fire. Electrical or electronic failure, if this is the reason, then there must be no warning before the car does not catch fire, very suddenly.

It may be that the battery is out of power, and the battery can only be replaced if the battery is out of power, which will generally occur after two or three years of battery use. If you exclude that the battery is out of power, you should fire it twice more to warm up the ignition system of the car, because the temperature is too low in winter, and I hope to adopt it.

In the case of the battery, it may be that the voltage is low, because the starting voltage needs to be above volts, below which it is difficult to start, despite the electricity.

There are two main ways to deal with the car battery when it is out of power and cannot catch fire: 1. Lap the wire. If your car is equipped with a cable, or you can borrow a cable, you can borrow the battery of another car to ignite your car, but it should be noted that the very low temperature in the northern winter may freeze the battery, if this is the case, you can't use the cable to save yourself.

Second, the cart "combustion". If we don't have any tools at hand, the easiest way is to use a cart to help light the fire. However, the cart needs several conditions, first, to ensure that there is still some surplus electricity in the battery, if the battery is completely consumed, the cart is useless; Second, the trolley method is only for manual transmission models, and automatic transmission models cannot be started by using the cart method, and can only be used to use the method of hitching or towing to the 4S shop for maintenance with a flatbed rescue vehicle.

The principle of "pushing" the car is to push the car by manpower, and the cylinder piston of the kinetic energy reaction is used to force the gas in the cylinder to be compressed and burned, and if everything else is normal, the generator will charge the battery once it starts.

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.
