What should I do if the car is not good when it is cold, and what is the matter with the car when it

1.It is difficult to ignite vehicles due to low temperatures.

1) Battery problems.

Cold weather can reduce the energy of a car's battery. Because the electrolyte in the battery will undergo a chemical reaction, and the operating temperature of the battery is generally between -10 degrees and 50 degrees. If the temperature is too low, the activity of the chemical components decreases, the reaction rate slows down, and the energy produced decreases.

In addition, at low temperatures, the viscosity of the electrolyte increases, and the resistance increases, which reduces the electrical output power. At this point, it is difficult for the starter to drag the engine. At the same time, as the voltage at both ends decreases, the ignition of the spark plug also weakens.

2) Oil and gasoline issues.

At low temperatures, the viscosity of the lubricant also increases, which means that the fluidity of the oil becomes poorer. Lubricating oil is meant to help the engine run, but this situation prevents the crankshaft from reaching the speed required for starting, making it difficult for the engine to start with resistance. Gasoline suffers the same thing.

When the engine is low, heat absorption will affect the temperature of the mixture, causing most of the fuel to enter the cylinder in a liquid state, causing the mixture to be too thin and difficult to start.

2.The car itself is difficult to ignore.

In this case, it is difficult for the car to ignite under normal temperature conditions, and the temperature drop increases the difficulty of ignition. On the one hand, there is the issue of car maintenance. Owners can recall whether their cars have been regularly inspected and maintained.

For example, the throttle valve controls the entry of gas in the intake pipe, which is then mixed with gasoline to become a combustible mixture. Gas combustion gives power to the engine. If the throttle is clogged with sludge, it will be difficult for the car to start without fresh air.

In addition, if the combustion system is not clean, the fuel will be adsorbed by carbon deposits, resulting in insufficient gasoline combustion to provide power. On the other hand, there is the ignition system failure. The main reason is the failure of the ignition coil, spark plug, high-voltage wire, ignition controller, etc.

Severe ablation, deposits, damage to the wiring or non-compliance with the requirements of the vehicle can prevent the car from catching fire.

3.How to fix it.

If you understand the reasons for the difficulty in igniting, you will be able to "prescribe the right medicine". The quicker way is to start together with the throttle, but we have to find the real source of the problem afterwards. The service life of the battery is 2-3 years, if it expires, it needs to be replaced, or use a car battery with the same nominal voltage; When the temperature is low, try to use oil with low viscosity, and also ensure the quality of lubricating oil and oil; For the intake and exhaust system and fuel system, go to the regular 4S shop on time for cleaning and care, and cannot be disassembled at will; Go to the repair shop to test the parameters of various electrical indicators; For failure problems, either repair or replace.

In addition, cold start fluids can be used appropriately. In winter, when the engine is difficult to start, the starting fluid is injected into the cylinder. Remember not to abuse and over-rely on it.

4.Precautions.

Some of the things that are normal when the weather gets cold and are not good for ignition, so car owners should not rush it. If the first ignition is not completed, do not keep turning the battery. Wait for a minute or so and try again.

Due to the low temperature in winter, the viscosity of the engine oil will increase, and the flow of oil will be more difficult, so that the engine resistance will increase, and then the car will not be good to ignite when the weather is cold.

Driving a car in winter should do the following:

1. In winter, the car should be started no more than 3 times in a row. Many cars have difficulty starting at low temperatures, and sometimes they turn off while driving. It is best to control the starting time within 5 seconds, if the start is not successful for 3 times, you should stop for a few minutes before continuing to start, so as not to damage the battery.

2. After the engine works, turn on the radio and other electrical equipment, turn off the electrical facilities and then turn off the engine before stopping, because after the vehicle is turned off at night, the battery is still in a state of discharge.

3. After the car starts, don't rush to high-speed driving, first have a warm-up time, start with the lowest gear, and gradually accelerate the car to have an adaptation process, which can improve fuel economy.

The correct way to warm up the car in winter: start in place and wait for three to five minutes, start the vehicle at a low speed, at this time you need to control the speed at about 2000 rpm, and wait for the water temperature of the engine to come up and you can drive normally.

The reason for the difficulty of igniting a car in cold weather is that the oil circuit is not smooth, the second is the old battery, and the third is caused by improper use: 1. First of all, the problem of poor oil road is directly related to the severe cold weather in the northern winter. This is because the viscosity of the oil increases as the temperature decreases, which increases the resistance of the engine and makes it difficult to start the car.

2. The solution is very simple, one is to change the special engine oil for the car in winter below 10w; The second is to try to avoid parking the car for a long time outside the cold household, and try to choose a garage or sheltered place to park; 3. Secondly, the old battery is also the reason why it is difficult for the car to catch fire in cold weather. Generally speaking, the service life of a car battery is between 2-3 years and should be replaced after a period of use.

The lower the temperature, the higher the viscosity of the oil, the lower the fluidity, and the greater the resistance of the engine, resulting in the difficulty of cold starting. The solution is to park the car in a high temperature environment after a period of time can start normally, in a particularly cold place to slip before cracking, if this problem may cause difficulties in starting, it is recommended to replace the oil used at low temperature in time.

There are also the following reasons why it can't catch fire in cold weather:

1. Check the status of the battery, most of the difficulties in starting the car in winter are caused by the loss of battery power or the expiration of the battery service life. When the battery is insufficient, the speed is weak when starting the car, and only the sound of clicking and repenting is heard, and the click sound will gradually become the sound of letter closure when the ignition is turned on. Do not ignite continuously to avoid the battery running out.

2. Replace the spark plug in time, the spark plug is easy to cause carbon deposit, 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. 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.

Phoenix.com - The car can't catch fire? Don't worry, lock these 3 reasons, everything is easy to do!

There are many reasons why a car cannot catch fire in cold weather, most of which include low engine temperature, spark plug failure, car running out of gas, battery failure, and the number of steering wheels quietly locked. The specific causes and solutions are as follows.

1. The engine temperature is too low

When the ambient temperature is too low, the engine temperature will not affect its internal fuel, and all kinds of engine oil will not work normally, and the car will have difficulty in starting or unable to start. This situation is fairly simple to deal with and can be resolved automatically as soon as the ambient temperature returns to normal levels.

2.Spark plug failure:

If the spark plug is faulty, the car engine will not start properly. So it doesn't start naturally. If the spark plug is clogged or dirty and the car does not catch fire, it must be removed and cleaned. If the spark plug is broken and the car does not catch fire, then it will have to be replaced directly.

3.The car is out of gas:

4.The battery is dead :

If the battery is dead, the car starter and spark plug will not work properly. In this case, the battery should be charged.

5.The steering wheel is locked:

In this case, it is enough to ignite while hitting the steering wheel.

This is the end of the introduction of what to do if the cold car does not catch fire. I hope Bian Xiao's introduction today can help everyone. If you like it, give Bian Xiao a compliment. This is the biggest support for Bian Xiao.

I believe that many car owners will encounter how to quickly solve such a small car problem when the car is not on fire when the car is cold, so the following will introduce you to the solution to how to quickly solve this problem when the car is cold and not on fire, I hope to help you solve the problem. Some car owners in the north have encountered the phenomenon that the car is not easy to start in winter. What should we do at this time?

First of all, we need to know which reasons are not easy to start and related to temperature.

The factors that affect the start of the engine are: air intake system, oil supply system, ignition system, lubrication system, etc.

Air intake system: When the weather turns cold, after the fuel is injected into the intake pipe, the atomization effect is not good. If there is carbon deposition in the engine intake system at this time, part of the fuel in the mixture is adsorbed, and the mixture is not easy to ignite in the cylinder.

Then at this time, we can consider cleaning the engine intake and throttle valves.

Oil supply system: It is difficult to establish oil pressure in the engine oil supply pipe, which mostly occurs in the morning when the temperature is particularly low. Due to fouling of the fuel lines or nozzles, when the temperature is particularly low, the fuel lines can become clogged with a mixture of water and impurities in the fuel, making starting difficult or impossible.

The solution is to completely solve the ignition fault by cleaning the oil circuit.

Ignition system: When the weather is cold, if the ignition ability is too weak, it is difficult to ignite the mixture with poor atomization effect. At this time, it is necessary to consider checking whether the spark plug has an excessive aging gap and whether the ignition coil is aging.

In addition, when the weather is cold, the capacity of the battery is also reduced. We can judge whether Kaiye's battery is out of power through lights, speakers and other electrical equipment.

Lubrication system: At low temperatures, the viscosity of the oil will increase, the flow of oil will become difficult, and the resistance of the engine to start will also increase, making it naturally difficult for the car to ignite. Therefore, in winter, it is more appropriate for us to use oils with lower viscosity.

Generally speaking, it is a very common reason when the weather is cold, especially remind the majority of car owners: if there are system difficulties, the start time should not be too long, and it is best to control it within 5 seconds. If it does not catch fire after 3 starts, you need to stop for half a minute to avoid damaging the battery or causing excessive fuel build-up in the cylinder.

Millions of car purchase subsidies.

1. Check your spark plugs, replacing them in time will make it easier to light the spark.

2. Do not add water or inferior antifreeze to the car without permission, it is easy to freeze the engine, so use a good antifreeze.

3. It is easier to open the choke door to start the fire, but close it immediately after igniting the fire.

4. Use your foot to start the lever a few times, and then use the key to start the motorcycle, although you don't know the principle, but many people do it.

5. Try to pour some hot water on the engine and preheat it, which is more effective.

6. The car is similar, as long as you pay attention to the parking method, you can solve the problem. Keep the front of the car facing the building, and use the building to block the wind and prevent the engine from being blown by the cold wind and getting too cold.

7. Insert the key and wait for a while before ignition, this is the correct way to ignite the stove, which can make the adjustment of the various sensors of Rotten Qingshan complete, which will not endanger the car's hunger, and it will be easier to ignite the fire.
