What should I do if the temperature is more than 20 degrees below zero, and the car can 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 freezes 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.

Precautions: 1. The car should check the battery frequently, if the battery has been exhausted more than twice, it is recommended to replace the new battery.

2. In winter, car owners who often don't use the car can let the car run at high speed, so that the water in the exhaust pipe can be discharged in time with strong exhaust force.

3. In addition, it is necessary to use gasoline additives that professionally clean up carbon deposits. You can go to the 4S shop for professional winter maintenance and change the appropriate engine oil according to the local situation.

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!

The car can't catch fire because the temperature is too low for the fuel to vaporize, so if you want to ignite, you can change to higher quality gasoline, or you can raise the temperature around the car.

You see if your car's battery is charged, if not, you need to take the battery.

1. Insufficient battery power may lead to difficulty in starting the car in winter, because in the low temperature environment, the power consumption of the car will be significantly greater than in other seasons, and the battery will also reduce the electric capacity due to the low temperature environment.

Second, several other reasons for the difficulty of starting the car in winter:

1. The flow of oil is blocked.

In winter, the viscosity of the engine oil will increase, and the flow of oil will become more difficult, so that the engine resistance will increase, which will cause the car to start difficult in winter, especially in northern cities.

2. The exhaust pipe is frozen.

Exhaust pipe freezing occurs mainly in car owners with closer trips. Their cars are used infrequently, and the water vapor after the combustion of the engine freezes on some parts of the exhaust pipe, and the short distance is not enough to melt these ices, and over time, it will have an impact on the starting and exhaust of the vehicle.

3. Electronic throttle carbon deposition is stuck.

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". When the engine is turned off, the temperature of the entire engine drops, and these dirty things become more stubbornly fixed to the throttle, making the throttle less flexible, so that the throttle will jam when it is turning.

You said that it can't catch fire, yes, is it enough for the starter to drive the engine to revolution? Or does the starter simply not move the engine to spin? If it is the first case, it means that the temperature is too low and the fuel atomization is not good, such as diesel vehicles.

As the saying goes, if the oil is frozen, it should be warmed up before trying. If it's the latter, then the battery capacity has dropped and needs to be replaced, and then it's to check the vehicle for self-discharge, such as turning on the radio? Lamp.

Yes.

The car can be started at minus 50 degrees. Under normal circumstances, when the temperature is between minus 10 and minus 15, it will be difficult for the car to start cold. When the temperature drops below minus 50 degrees, the car can only be started after preheating, and the car cannot be started without preheating.

Therefore, when it is minus 50 degrees, be sure to warm up before starting the car. In addition, more attention should be paid to the maintenance of the car in a low temperature environment.

Precautions for car ignition.

For when starting the vehicle, it is recommended that the vehicle screw the key and hold it for about 15 seconds, if it cannot start normally, release the key should wait at least 15 seconds to cool down the starter motor, if the engine is started continuously for a long time will cause the starter motor to overheat or be damaged, and will consume battery power.

After the engine starts, release the start button or ignition key, and retract the accelerator pedal as soon as possible to ensure that the engine does not stall to avoid high-speed operation of the engine. If the vehicle stops again after a short start, the same measures should be taken. This will remove excess gasoline from the engine.

At present, it will be more difficult to start at minus 40, most cars need to extend the single start time or multiple starts, and some cars even need an external power supply to start. At present, the EFI calibration of domestic automobile engines is mainly UMC and Delphi, and the general cold start standard in the industry is -30. Lower temperatures are generally not mandatory.

When the temperature is below 30°C, it is difficult to start, but it is generally possible to start it after two more starts. If it doesn't work, it will be powered by an external power supply.

In addition, attention should be paid to low temperature starting:

1. If possible, in extremely cold areas, try to stop in the warm storage, which is the simplest and most effective way;

2. Change the engine oil suitable for low temperature;

3. If it is difficult to start, start with an external power supply in time, and do not start continuously for many times, which will easily lead to the flooding of the engine.

It depends on what kind of oil you use, antifreeze or something, and the model of the engine oil.

The smaller the better, the bigger the better, the bigger the better, the bigger the better, the example: 5w-30

W stands for winter is the abbreviation of winter, the smaller the number before w, the smaller the low temperature viscosity, the better the low temperature fluidity, and the lower the applicable minimum temperature; The grades of winter oil are: 0w, 5w, 10w, 15w, 20w, 25w, the larger the number, the greater the viscosity, the higher the applicable maximum temperature;

We had the coldest minus 30 and no problem starting. Pay attention to the choice of oil, antifreeze, glass water and battery maintenance.

There are no problems with petrol cars.

Diesel vehicles mainly depend on whether the fuel of the vehicle is up to standard.

Hello, this one doesn't need to change gas, I hope it can help you!

At minus 10 degrees, my car won't catch fire.

Qinqin is very happy to serve you minus 10 degrees, the car can not catch fire causes and solutions: 1. The most direct impact of insufficient battery power on family cars in winter is the battery. At low temperatures, the electricity consumption of the car will be significantly higher than in other seasons.

The capacitance of the battery will also be reduced due to the low temperature environment. Batteries that have been used for a long time will have a low initial starting voltage. If dirty oil adheres to the surface of the battery, the voltage output will be unstable, resulting in the body shaking.

Timely replacement of new batteries or replenishment of batteries can effectively avoid this situation; 2. When the throttle starts with carbon deposition, the fuel is too thin, the oil supply is poor, and the fuel will wet the spark plug, which can not start normally, which is due to the liquid state flowing into the cylinder, which produces depression in the upper part of the cylinder piston, when the piston runs up and down, the fuel is splashed on the electrode of the spark plug, so that it cannot work normally, and the start fails; If the above situation occurs, it means that your car needs to be thoroughly maintained, and the carbon deposits in the intake tract, throttle and cylinder have been removed; 3. Exhaust pipe freezing or valve carbon deposition will also make it difficult to start the engine, the exhaust pipe freezing is mainly due to the low frequency of car use in winter, the water vapor generated after engine combustion freezes in a certain part of the exhaust pipe, and the short-distance driving can not melt these ice, and a long time will have an impact on the start and exhaust of the car. Use hot water to dispense.

1. Change the oil

In winter, due to the low temperature, the oil is affected by low temperature, and the viscosity becomes larger and the fluidity is poorer. As a result, the resistance of the engine also increases, and it is difficult for the engine to ignite. At this time, you can move the car to a warmer environment to restore the fluidity of the oil.

It is also possible to change to a higher quality engine oil, which can withstand low temperatures.

2. Replace the antifreeze

Antifreeze cools the engine and prevents freezing in winter. However, at low temperatures, if the quality of the antifreeze is not good enough, or if it is mixed with water, it will be frozen, resulting in the car not catching fire. The correct thing to do is to replace it with a better quality antifreeze.

3. Replenish the power of the battery

The low temperature in winter will affect the charging performance of the battery, and the power consumption of the battery is relatively fast, and the car is easy to fail to catch fire if the power is insufficient. It can be used with other cars to replenish the power of the battery in time.

4. Replace the spark plug

When the engine fails to ignite, or when performance is degraded, it is most likely that there is a problem with the spark plug. Spark plugs can be replaced with new ones.

5. Pay attention to daily maintenance

The car can't catch fire when the temperature is low, mainly because the usual maintenance is not in place, so pay more attention to the maintenance of the vehicle at ordinary times, and go to the 4S shop on time to check all parts of the car, so that the car has been in the best condition, so that when it is cold, the car can start smoothly.

1. The flow of engine oil is blocked, change the appropriate oil.

In winter, the viscosity of the oil increases, making it difficult for the oil to flow, which increases the resistance of the engine. The emergency solution is to put the car in a warm environment, and after a period of time, it can start normally. However, the first car network Xiao I suggests that the owner should do a maintenance for the car and change the appropriate oil.

2. If the battery is insufficient, it should be replenished in a timely and effective manner.

It is most common for the battery to lose power or the battery life to expire. 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. Try to refuel the car when you twist the key, press the accelerator continuously, and when the car shakes and is about to start, loosen the accelerator to avoid damaging the vehicle by pressing on the accelerator.

Do not ignite continuously to avoid the battery running out. The service life of the battery is generally one and a half to three years, and it should be replaced in time after this period. In winter, if you park for a week, you need to drive the vehicle out for a lap to effectively replenish the battery power.

The main thing is to see that the engine is not oiled, and it is recommended to change the oil to a higher grade, which has an old way of heating the oil pan of the engine.

Change the oil to a lighter one and check that the spark plug is not flooded.

The car can't catch fire at more than 20 degrees below zero, and if it is connected, it will be easy to fight again, which is for two reasons:

1. The anti-freezing capacity of the vehicle's oil is too low, that is, the temperature is too low and condensed, and the driving force of the starter cannot overcome this resistance, so it can't be started, and it can be solved by changing the antifreeze oil.

Second, the battery power is too low, the slightest resistance is not enough to drive the engine, then you need to charge the battery, the specific operation steps are as follows:

1. Open the door on this side of the cab.

2. Pull the hood switch on the left side of the driver's leg.

3. Support the hood with a support rod to ensure that the support is firm to avoid danger.

4. The red positive electrode of the charger corresponds to the red positive electrode of the battery.

5. The black negative electrode of the charger corresponds to the black negative electrode of the battery.

Notes:1. Do not reverse the positive and negative poles.

2. Charge within 8 hours.

This is quite normal. The car has been used for a while. The oil pressure retention system has deteriorated.

The oil pressure is not easy to maintain. In the case of low temperature, the oil is relatively thick, so when starting for the first time, the oil will slowly come up, so the sealing in the cylinder is not good, and the cylinder pressure cannot meet the ignition requirements. So it's not good to start.

This all improves when the second ignition occurs. So it's good to start. If you want to improve this situation, you can add an engine preheating system to the car.

You can start the warm-up system remotely when you're at home. Half an hour later, you get off and the taxi will be lit. Hope it helps.

You said that it can't catch fire, yes, is it enough for the starter to drive the engine to revolution? Or does the starter simply not move the engine to spin? If it is the first case, it means that the temperature is too low and the fuel atomization is not good, such as diesel vehicles.

As the saying goes, if the oil is frozen, it should be warmed up before trying. If it's the latter, then the battery capacity has dropped and needs to be replaced, and then it's to check the vehicle for self-discharge, such as turning on the radio? Lamp.

The car can't catch fire at more than 20 degrees below zero, because the temperature outside is too cold, and it's good to hit it again, because it rubs and heats.

Hello! Your car is so cold that it needs to be kept warm with cotton or sponge foam, or just roasted with heat, and there is a lot of gasoline or diesel that has solidified and needs to be warmed up to start.
