What should I do if my car doesn t catch fire in winter?

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.

Solution 1: Start across the board.

Steps: 1. Bring the two vehicles close together until the jumper cables are enough to connect the positive and negative poles of the two batteries. Care should be taken to ensure that the two vehicles are not in contact and only cables with sufficient load carrying capacity and insulated sheath are allowed.

If the battery providing the power supply is not installed in a position on the vehicle that is convenient for direct jumping, the battery must be removed using a tool.

2. Determine the positive electrode (+) and negative electrode (-) of the two batteries, and use cables to connect the positive electrode and the positive electrode, and the negative electrode and the negative electrode respectively. It is necessary to pay attention to the positive and negative poles of the battery, and to ensure the reliable connection of the cable. Arrange the direction of the cable to prevent the cable from scratching with the tape or fan when starting.

3. Turn off all the ancillary electrical equipment on the car, start the vehicle where the battery providing power is located, and make the engine run for a few minutes to ensure that the power is sufficient. Then start the non-electric vehicle in the normal way, and gently press the accelerator pedal after starting, so that the engine runs for a few minutes at 2000r min. 4. Turn off the ignition switch of the two vehicles, carefully remove the cable, and pay attention to avoid the positive and negative cable joints from colliding.

Solution 2: Start the cart.

Steps: 1. First of all, you should pay attention to safety. Observe whether the road conditions of the vehicle's parking position are suitable for the cart to start, for example, you can increase the speed of the vehicle with the help of a downhill road, if the front of the car is an uphill road, then it will be very tiring to push the cart forward, and it is difficult to increase the speed, so you should turn the head of the vehicle to push the cart in the downhill direction.

Try not to start the cart on a road section with a lot of vehicles and pedestrians, so as to avoid accidents caused by improper response by the driver after the vehicle is started.

2. The ignition switch should be turned on before the vehicle is pushed, and after reaching a considerable speed, the transmission should be put into 2nd gear, and then the clutch pedal should be quickly released and refueled. Once the engine starts, you should quickly press the clutch pedal, control the throttle at the same time, do not let the engine turn off, and then stop slowly.

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 the battery is out of power, light it twice more and let the car's ignition system warm up, because the temperature is too low in winter. Hope!

There are many reasons why the car cannot catch fire in winter, and the following points are more common: the battery is low because the temperature is low, and the oil temperature is low and the fluidity is poor at low temperature.

There are many reasons for this, so it is recommended that you go to the 4S store to check it yourself, and then do specific treatment after finding the reason.

Hello, it is recommended to go to the repair shop for inspection.

This is fine, but make sure that the coolant of the car is not icing. The weather is too cold, the cylinder is too cold, and the spark plug is too cold, resulting in the inability to produce **, so it cannot ignite.

An easy way to dig is to take a ball of cloth, dip it in a little gasoline, light it in front of the air intake, and start the car. At this point, the engine draws the hot air in front of the air intake into the cylinder, and the car is much easier. In addition, the sound of the belt is also the reason for the cold of the car.

If it keeps ringing, it's time to check.

Reasons why the car won't catch fire:

1. If the car does not catch fire, first consider the battery power. Due to the falling of the battery plates, or the pH balance of the ratio is incorrect, the battery storage is insufficient.

2. The exhaust pipe is frozen or the valve has too much carbon. The main reason for the exhaust pipe freezing is that the frequency of use of the car is too low, and the water vapor after the combustion of the engine is frozen on some parts of the exhaust pipe. Over time, it can have a significant impact on the start and exhaust of the car.

3. Carbon deposits. It is easy to produce carbon deposits when driving at low temperatures for a long time, the quality of gasoline is too poor or the car is used for too long, and the engine oil is burned.

4. The flow of engine oil is blocked. In winter, the viscosity of the engine oil increases, and the oil does not flow smoothly, so the engine resistance increases, which makes it difficult for the car to start coldly in winter, and this phenomenon is more pronounced in northern cities. You can put the car in a warm environment, and the car can start normally after a while.

The following is the solution to the leakage of the vehicle that does not catch fire in winter: 1. Check the state of the battery, when the battery is insufficient, the speed is weak when starting the car, and only the click sound is heard. Do not ignite continuously to avoid the battery running out.

Do not park the vehicle for a long time in winter, generally park the vehicle for a week to drive out for a circle, so that the battery power can be effectively replenished. 2. Replace the appropriate engine oil, in winter, as the temperature decreases, the viscosity of the engine oil will increase, and the oil flow will be difficult, so that the engine resistance will increase. If it is difficult to start the dipstick, you need to check whether the oil label is incorrect.

The oil label consists of two parts: grading and viscosity specification. 3. Replace the spark plug in time, the spark plug is easy to cause carbon deposition, leakage, excessive gap, ablation and other problems after a few years of use, which will cause the ignition of the car is difficult, and it is difficult to start the cold start and even the hot engine, and it is often necessary to ignite many times. The spark plugs need to be inspected and replaced.

It may be that water or inferior antifreeze is added, causing the waterway to be frozen or even the engine is frozen and cracked, and the car water pump cannot work and cannot ignite, the solution is naturally to add high-quality antifreeze after inspection and repair; It may be that the throttle has carbon deposits, resulting in insufficient pressure on the gasoline and cannot ignite, etc., and the solution is to clean up the carbon deposits. 1. The main manifestation of battery power loss is that the starter starts to rotate but the speed is not enough, that is, the start is weak, and even the starter just clicks but does not turn. This situation may be due to the fact that the vehicle cannot be started due to the forgetting to turn off individual electrical equipment in the car, especially for long-term short-distance use in winter, the battery voltage will be lower than the rated value, and the starting cannot operate normally.

The solution is that you can hit the ** rescue, or find a car to catch fire, and after the fire, it is best to go to the repair shop to replenish the battery. 2. The obstruction of gasoline flow is generally manifested as no oil pressure in the engine fuel supply pipe, which mostly occurs in the morning when the temperature is particularly low, due to the long-term dirt of the fuel pipeline, when the temperature is particularly low, the water is mixed with debris so that the fuel pipeline is not passable, and the result can not start. The solution is to put the car in a warm environment, and the car can start in a while; Or use the method of cleaning the oil circuit to solve it completely.

3. Ignition system failure. Due to the low intake air temperature in the cylinder, the fuel is not atomized well in the cylinder, if the ignition energy is insufficient, it is easy to lead to the phenomenon of flooding, and too much fuel accumulates in the cylinder, exceeding the fire limit concentration and unable to land. The solution is to unscrew out the spark plug to wipe off the oil between the electrodes, and it can catch fire 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.

The battery is not on power。The most direct impact of winter on family cars in the city is the battery. At low temperatures, the power consumption of the car will be significantly higher than in other seasons, and the battery capacity will also be reduced due to the low temperature environment.

If you go to the franchise store in time to replenish the battery or replace the battery with a new one in time when winter comes, you can effectively avoid this situation.

Oil flow is blocked。This is more pronounced in northern cities where temperatures are particularly low. In winter, the viscosity of the oil increases, and the oil flow becomes more difficult, which increases the resistance of the engine, which makes it difficult for the car to start coldly in the winter.

In this case, the emergency solution is to put the car in a warm environment, and after a period of time, it can start normally. But if you want to solve it completely, it is best to go to a franchise store to do a professional winter maintenance and change the appropriate engine oil according to the local situation.

The exhaust pipe is frozen, electronic throttle deposition stuck and so on. Exhaust pipe freezing mainly occurs in those car owners who are relatively close to their homes. Their cars were used infrequently, and the water vapor from the combustion of the engine froze on some parts of the exhaust pipe, and the short drive was not enough to melt the ice, and after a night more ice formed.

Over time, it will have an impact on the starting and exhaust of the vehicle. Of course, the solution is actually very simple, run a high speed every weekend in the winter, so that the water in the exhaust pipe can be drained in time with a strong exhaust force.

In addition, the car's electronic throttle valve is a device used to control the flow of air into the cylinder and generate negative pressure. Due to the incomplete combustion of gasoline in the combustion chamber, tiny carbon particles are produced, which form what is often referred to as "carbon deposit". As the temperature of the entire engine drops when the engine is turned off, the dirt becomes more stubbornly attached to the throttle, making the throttle less flexible, so that the throttle will jam when it is turning.

As the temperature decreases in winter, it is recommended that car owners periodically clean the electronic throttle to completely eliminate the unstable idle speed and increased fuel consumption caused by carbon accumulation on the throttle.
