The car can t be pushed on fire, but it can be ignited with a battery

The fault phenomenon should be a serious leakage of the car battery, such as insufficient pressure, flooded cylinder, broken computer board, etc., which may cause the ignition, which should have been cut off The electrical equipment has not been cut off. When the battery is seriously fed, the car will not be able to push it. Only use other batteries to go and merge.

Generally, when the battery is out of power, other electrical equipment is also greatly affected, try whether the horn and lights are normal, if not, check whether the battery pile head connection is loose, the pile head is normal, the manual transmission of the car can be pushed to start. The automatic transmission only has a parallel battery and then ignition. If none of the above fails, check the starter.

There is no direct relationship between the failure to catch fire and the generator.

This shows that the repair shop has not really found the cause of the failure. According to what you said, the fault phenomenon should be a serious leakage of the car battery, which may be which electrical equipment that should have been cut off has not been cut off. When the battery is seriously fed, the car will not be able to push it.

Only use other batteries to go and merge. It is recommended that you go to a more formal station to have a look, and it should be able to solve it.

There are many reasons why the car cannot start, and it is impossible to explain them one by one, so let's briefly talk about the diagnosis idea.

1. Turn the ignition switch (key door) to the starting position to see if there is any response. There is a reflection (the sound of the motor starting) to proceed to step 2.

No response means that the starter is not working.

Listen to the starter (you can generally hear it when you open the door in the car, preferably if someone listens to it next to the engine compartment) for the sound of "click, click"; There is a sound, the magnetic switch is no problem, [the fault of the starter]; There is no "click, click" sound, [magnetic switch failure]; Note that you must first make sure that the starting circuit is electrified.

2. Listen to whether the starter is loud (driving the engine) sound or a skidding sound (like an electric toy car). Proceed to step 3 with a loud voice.

Slipping (like an electric toy car) sound indicates that the starter is weak or [starter wheel failure], measure the battery starting voltage, the tool is "battery tester" or "battery gun", if you do not use a multimeter, but you should measure it when starting, see if the starting voltage is enough (generally above 12 fords), the starting voltage is enough, and the [starter wheel failure] is replaced. If not enough, proceed to step 3

3. If it is a manual transmission car, use 3 gears for carts or traction; If it is an automatic transmission car, use a battery that can be determined to be a good one; It can be started and replaced by [battery failure]. If it still can't start, the manual transmission car, [engine failure]; Automatic transmission car, see whether the engine speed is to the starting speed - to the starting speed, [engine failure]; Failure to reach the starting speed [starter failure].

The above steps need to rule out the situation that the battery voltage cannot be guaranteed even if the engine is normal.

As for generator failure, it is a separate diagnostic process.

But depending on your experience, the repair shop is experimenting one by one, without the process of judgment and troubleshooting.

Is yours a diesel or petrol car? I feel like it's a problem with the generator.

The remaining 30 percent of the car's battery is electricCan't catch fire, if the remaining life is only 30%, it is absolutely necessary to replace, the battery is a wearing part on the car that needs to be replaced regularly, if there is no battery, the car is unable to operate normally, when starting the engine, the starter, fuel supply system, ignition system, etc. all need to run.

The operation of the above system is inseparable from electricity, if the battery is out of power, the engine of the car can not start normally, after starting the engine, the engine will drive the generator to run, the generator can supply power to the electronic equipment of the whole car when running, and can charge the battery.

The introduction of car batteriesVehicle battery, the battery used in the car, is a device that converts chemical energy into electrical energy, which is a DC power supply, which provides a strong starting current to the starter when the engine is started, and when the generator is overloaded, it can assist the generator to supply power to the electrical equipment, when the engine is at idle speed.

When the voltage at the generator end is higher than the electromotive force of the lead-acid battery, a part of the electrical energy is converted into chemical energy and stored, that is, it is charged, which is divided into two types: traditional lead-acid battery and maintenance-free battery.

The former is composed of positive and negative plates, separators, shells, electrolytes and terminal heads, etc., and the chemical reaction of discharge is carried out under the action of electrolyte by relying on the active substances of the positive plate and the active materials of the negative plates, in which the grid of the plate is made of lead-antimony alloy, and the latter is made of lead-calcium alloy, and the sulfuric acid gas released is also less, no need to add any liquid, and the power storage time is long.

If the car battery is out of power, it will definitely not catch fire, you can find a friend's car to connect his battery to start your car.

Can you try it on the fire to know, but you can't light the fire to say that the battery may be out of power. If you already know that there is no electricity, of course, you can't catch fire.

1. The amount of fuel is insufficient, and when the car has no power ** "gasoline", it will naturally not ignite. If it is caused by the lack of oil, then this situation is easy to solve.

2. The wrong gear of the car may also cause the car to not catch fire. 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.

3. Circuit or electronic failure, if this is the reason, then there must be no warning before the car does not catch fire, very suddenly. Circuit failure: fuse blowing, high-voltage coil breaking, low-voltage circuit breaking, center ignition wire falling off, splitter head leakage, spark plug damage.

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

4. Oil circuit failure, oil circuit failure may occur in the following parts: oil pump failure, oil circuit failure, oil filter blockage, spark plug carbon deposit, fuel injector damage and so on.

The gear cannot be ignited when hung on the D gear, which is the self-protection mechanism of the car to prevent the car from moving after ignition;

The gasoline pump is damaged and the oil cannot be pumped;

The serious carbon deposition of the throttle valve leads to insufficient throttle opening, and the combustible mixture cannot enter the cylinder for combustion, resulting in the failure to start.

Ask questions with electricity.

That requires checking the throttle.

The car does not catch fire involves a wide range, and you need to check it one by one to know what the cause is.

There are three ways to use the car battery when it is out of power and cannot ignite: the first can use the cart emergency start, of course, this is only for manual transmission models; the second is to borrow the car wiring bridge to start; The third is to use a mobile emergency power bank to start charging.

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. When the dashboard shows that the battery is insufficient, the battery should be charged in time. If the car is parked for a long time and is not in use, the battery will slowly lose power even if it is idle.

Therefore, if you do not use the car for a long time, remember to disconnect the battery wire, or start the car to run for a period of time every once in a while to let the generator charge the battery.

When using the car at ordinary times, it is best to check whether the positive and negative poles of the battery are oxidized, whether the circuit is aging or short circuit, and check whether the connection parts are firm and whether the terminal surface is clean to ensure good contact. In addition, it is strictly forbidden to place metal tools and conductive objects near the battery terminals, so as to avoid metal objects and battery poles colliding, resulting in short circuit ignition and burning of the battery and terminals.

If the vehicle does not have automatic headlights, be sure to turn off the lights when you get out of the vehicle and before leaving. Turning off the lights for a short time will not cause obvious adverse phenomena, but if the vehicle is in this state for a long time, it will cause the battery to be discharged rapidly until the power is lost, and the battery life will be damaged.

The car has electricity, it can't catch fire, considering the abnormal engine, you can open the door first, you can use the battery of other vehicles to take the power, and you can open the door after the car is powered on.

Prepare the material: digging hood.

A jumper start line, a rescue vehicle.

Specific steps: 1. When the vehicle loses power and cannot be started, the wiring method is generally used to start the car, and the car battery prepared by Changyuan Dou is wired.

2. Open the hood of the two cars and the protective shell of the battery to expose the positive and negative poles of the battery. Whether it is a rescue vehicle or a rescue vehicle, the operation of the battery should be carried out in the state of flame-off, and the positive and negative poles of the battery must be confirmed.

3. Take a tie wire, connect one end to the positive pole of the unpowered battery, and connect the other end to the positive pole of the electric battery. Do not touch the positive and negative electrodes, there is a danger of short circuit!

4. Take another wire, first connect the negative electrode with the electric battery, and then connect the other end to the negative electrode of the non-electric vehicle.

5. After the wire is set up, you can start the vehicle with power loss and open the door.

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.

First of all, we must know how to troubleshoot. We should first rule out whether the car does not catch fire, whether it is caused by too low temperature, or whether it is caused by the wrong gear. If it's either case, we can fix it ourselves.

If it is caused by serious carbon deposits in the engine, it is necessary to go to the repair shop to clean the engine.

Since any conditions have not changed, but the battery has changed, the root cause is still the lack of battery power, because the battery voltage that can be started normally, the 12-volt battery needs to be kept above the volt to start smoothly, and the volt above can be started, but it is not necessarily smooth.

The battery has electricity, and the car can't catch fire It should be that the battery aging causes insufficient power, and the battery needs to be replaced.

It means that the battery has been aged, the voltage and current are insufficient, and it can be solved by replacing a battery.

Today, I will explain to you the relevant knowledge about "the car does not catch fire, but the battery has electricity". This situation is caused by damage to the ignition system or fuel supply system, and it is recommended to check the ignition system and fuel supply system first. The main components of the ignition system of an automobile engine include an ignition coil and a spark plug.

The spark plug is an important component in the ignition system, and it is also a wear part that needs to be replaced regularly.

There is an electrode on the spark plug, which can release the electrical spark.

An electric spark can ignite a combustible mixture in the combustion chamber.

The combustible combustible mixture can be pushed down to run the piston so that the engine can output power.

However, as the time of use increases, the electrode gap of the spark plug also increases rapidly.

If the electrode gap becomes larger, the ignition energy of the spark plug will be weakened.

If the ignition energy becomes weaker, the combustible mixture in the combustion chamber will not be able to burn sufficiently.

This affects the engine's power output and fuel economy.

Therefore, the spark plug needs to be replaced regularly.

It is recommended that you regularly replace the spark plugs when you usually use the car, and when buying spark plugs, you must choose the model that suits your car engine.

When installing spark plugs, be sure to use a professional torque wrench to tighten according to the specified torque.

When using the car in ordinary times, everyone must maintain their car on time, and regular maintenance can keep the rubber car in good condition.

Millions of car purchase subsidies.

The workarounds are:

1. If it is a manual transmission vehicle, the car still has some power, and it just so happens that there are a few people around at this time, you can hang up the first gear, step on the clutch, open the car key to the ACC gear, let people push the car behind, when the speed of the car comes up, you can release the clutch, and the vehicle can be driven due to inertia.

2. The battery loss is serious, and it can only be solved by using the battery wire, when using the wire, the 12-volt DC power supply of the car should be used, and the positive and negative poles cannot be reversed, otherwise the accessories on the car may be damaged.

3. If there is a good car next to it, you can also use a wrench to remove the battery on the car, and then remove the battery with a loss of power, put the good battery on the car with a loss of power, and then restore the two batteries. When disassembling the battery, the negative electrode should be removed first, and then the positive electrode. When installing the battery, install the positive electrode first, and then the negative electrode.

Car battery maintenance.

1. Turn off all lights before turning off the fire.

Some older models do not support the function of automatic power off after the ignition is turned off, so you need to manually turn off the lights and the reading lights in the car before turning off the ignition. If you need to find something in the car or need lighting, you can use a mobile phone or flashlight to illuminate, so as to avoid forgetting to turn off the reading light and causing battery power loss.

2. Avoid parking the vehicle for a long time.

The battery installed in the car will discharge itself in the process of long-term placement, and many car owners will find it difficult to get into the car or even the battery is completely out of power after returning home from a business trip or tour, so it is best to drive the car once a week, and the journey is best to be more than 20 minutes, so that the battery can be charged when the vehicle is running.
