Why is it not good to ignite a car in winter 5

With the advent of the cold winter, many car owners have encountered the trouble of difficult to start the vehicle, sometimes even if it is started, the engine will also have serious shaking, and even the phenomenon of stalling, affecting the normal driving. In fact, whether it is winter or summer, when the cold car starts, you should do a "warm-up exercise". Reasons and precautions for the difficulty of starting the vehicle in winter.

The reason why it is difficult to start the vehicle in winter.

1. The fuel injector is dirty. After the vehicle is driven for a period of time, due to the chemical reaction of external dust entering and combustion process, it is easy to adhere some gum at the fuel injector site, which will block the normal amount of fuel injection and affect the perception sensitivity of the fuel injector, resulting in poor gasoline atomization, so that the ignition is delayed and the car is difficult to start.

2. The battery power is insufficient. 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 greater than in other seasons, and the battery will also become capacitive 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.

3. Low fuel quality. Generally speaking, the viscosity of fuel is higher in autumn and winter, and it is not easy to evaporate, which has a certain impact on the heat energy during combustion. Therefore, it is recommended that car owners choose regular gas stations to refuel, and do not be greedy for cheap and low-priced oil.

4. Throttle carbon deposits. When starting, the fuel is too thin, the oil supply is poor, and there will be the phenomenon of the fuel wetting the spark plug, which can not be started normally, because the fuel is injected on the carbon deposit at the gas door, after more accumulation, the fuel on the carbon deposit enters the saturated state, and the supersaturated state makes the fuel flow into the cylinder in a liquid state, and produces a depression phenomenon in the upper part of the cylinder piston, when the piston runs up and down, the fuel is thrown 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 are removed.

5. The flow of engine oil 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.

6. The exhaust pipe is frozen. Exhaust pipe freezing mainly occurs in those car owners who are relatively close to their homes. Due to the infrequent use of the car, the water vapor from the combustion of the engine freezes on some parts of the exhaust pipe, and the short drive is not enough to melt these ices, and more ice forms after a night.

Over time, it will have an impact on the starting and exhaust of the vehicle.

There are several reasons for this, battery power loss, gasoline flow blocked, ignition system working poorly, valve glue, exhaust pipe freezing, etc. The battery is ——— characterized by the fact that the starter starts to rotate but the speed is not enough, that is, it is weak, and then the starter only clicks and does not rotate. Low temperature in winter and forgetting to turn off individual electrical equipment will cause the vehicle to be unable to start, especially in winter for long-term short-distance low-speed use, the battery voltage will be lower than the rated value, starting and unable to operate normally.

If it happens, please call the service station for rescue**, or find the right car, or temporarily on fire, and then you must go to the service station to replenish the battery. Gasoline flow is blocked——— characterized by no oil pressure in the engine supply pipe. This situation usually occurs in the morning when the temperature is very low, and is caused by long-term dirt in the fuel line.

When the temperature is very low, the water mixes with debris and the fuel line is blocked, and as a result, it cannot be started. Emergency method: Put the car in a warm environment, and the car can start after a while; Or use the method of cleaning the oil circuit to solve it completely.

The ignition system is not in good working condition——— especially in cold weather, due to the low intake temperature, the fuel is not atomized well in the cylinder, if the ignition energy is insufficient, the result will be flooded cylinder, that is, too much fuel accumulates in the cylinder, exceeding the fire limit concentration and can not land. Emergency method: You can unscrew out the spark plug to wipe off the oil between the electrodes, and you can start the car 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. Valve gelatinization ——— winter cars, especially after the use of unclean gasoline, the non-flammable gum in the gasoline will accumulate near the intake, exhaust valves and combustion chambers, which will cause hard starting, or even no fire in the cold morning. Contingency Method:

You can drop some oil into the combustion chamber, and it can generally be started. After starting, go to the service station for disassembly-free cleaning, and dismantle and clean the cylinder head in serious cases. The appearance characteristics of the exhaust pipe freezing ——— are fog cylinder pressure, normal oil supply and power supply, and no car.

This situation is easy to occur in the use of particularly low frequency of vehicles, such as the home is particularly close to the unit, the water vapor after the combustion of the engine freezes at the muffler of the exhaust pipe, the ice of yesterday is not finished after short-distance driving, and today's ice is frozen, and the time is long, affecting the exhaust, and it is serious and cannot be started. The solution is very simple, put the car in a warm environment, and the ice can be started naturally. A complete solution can be to run at high speed in time, and the car will run more, and the heat from the exhaust will completely melt away the ice and expel it.

1. At low temperature, the battery reduces the output power due to the increase of electrolyte viscosity, the decrease of permeability, and the increase of resistance, which makes it difficult for the starter to drag the engine, and cannot reach the minimum starting speed, which affects the engine start. If the engine does not rotate or the speed is very slow when the car is ignited, it is very likely that the battery is dead or malfunctioning. You should find a battery with electricity and connect it to the car and try to light it.

2. Due to the low voltage of the battery terminal caused by low temperature, the spark of the spark plug is weak, and the density of the mixture increases the resistance between the electrodes, which makes it difficult to ignite the mixture and make it difficult to start the engine. At this time, check the spark plug to see if it is aging or heavy carbon deposits, and replace it with a new one if necessary. 3. Some old vehicles, oil pipes and other serious aging, the vehicle can not keep up with the oil when starting, often resulting in no ignition, so when igniting, you should step on the accelerator a little to make the gasoline cycle faster, so that it is easier to play.

4. Fill fuel in time. Some vehicles have inaccurate fuel gauge pointers, and when the fuel gauge is red light, fuel should be added in time. Otherwise, it will be difficult for the vehicle to catch fire if it can't keep up with the oil, especially in winter, when the temperature is very low.

5 If it is a diesel car, the situation of not catching fire in winter is more serious, the main solution is to replace the diesel in advance, especially the old diesel car, when the ambient temperature is about 0 degrees, it is recommended to replace the diesel of minus 10; When the ambient temperature is below minus 5 degrees, it should be replaced with minus 20; When the ambient temperature is lower, replace it with a diesel fuel of minus 30. ENDWhat tips when starting a car in winter1After starting the engine in winter, turn on the lights, radio, and other electrical equipment. Before stopping, turn off these power-hungry appliances and then turn off the engine.

2. When the car cannot be started for the first time, do not ...... the second and third consecutive lighters, which will only accelerate the consumption of electrical energy. And once the electricity is consumed, even the cart will not help. Therefore, if it fails to boot the first time, it is best to wait 30 seconds before making a second boot attempt.

Also, don't rush to drive at high speed after the car starts, give the vehicle a warm-up time, so that the vehicle is not easy to wear and tear and can improve fuel economy. Generally, when the water temperature wants to rise, refuel and drive quickly.

It is related to the density of the air, and the temperature of the air, the temperature is low, the mixture of air and fuel is poor, the air temperature in the cylinder when compressed cannot reach the necessary temperature when starting, and the pressure of the compressed air in the cylinder is also significantly lower than the pressure required for normal starting, and it is difficult to start.

The reason for the difficulty in starting is that when the temperature is below minus 25, the viscosity of the engine oil increases, and if the engine oil is not replaced in 0w winter, the mechanical resistance to start is large; In the case of low temperature, the fuel has poor volatility, poor combustion, and long-term short-distance driving, the water temperature cannot rise, resulting in more carbon deposits;

When the vehicle is parked outdoors in the cold for a long time, when the battery power is insufficient, the low temperature causes the battery activity to decrease, and the output power is insufficient.

Introduction: In the northern part of China, due to the relatively low temperature in winter, the car cannot ignite after being parked outside overnight, probably because the viscosity of the car's oil increases in cold conditions, and the lubrication effect cannot be achieved. The greeting of the warranty car or the car battery is easy to lose power in the cold season.

In the case of battery shortage, it will not catch fire, in short, there are many reasons why the car cannot catch fire. <>

Due to China's vast land and vast territory, when winter comes, there are not only Xilu Island, which is suitable for vacation, such as Sanya, but also cities in Northeast China with nine cold days. Why some northern cities when winter comes, the outdoor temperature is very low, many car owners have encountered the car parked outdoors overnight, the next day can not catch fire, what is the reason for this? First of all, it may be because the weather is too cold, and the antifreeze in the car has lost its protective effect on the vehicle due to too much time, or the oil of the car, because the weather is colder, the texture becomes more viscous, so the fluidity will also deteriorate.

As a result, the car's engine resistance increases, which makes it difficult to start. If it is because the engine oil has become more viscous, in this case it cannot be ignited, you can preheat the car for a while, and wait until the temperature of the vehicle rises, and the viscosity of the engine oil decreases at night, and you can start the fire. The second is that it has nothing to do with the temperature of the weather, just because the car battery happens to be out of power.

In this way, if you hit the flint and steel the next day, the car will not be hit. In this case, we must remove the car battery for charging in time, and replace it in time if it reaches a certain service life. <>

In addition, there is also a possibility that the outdoor combing temperature is too low, and the antifreeze added to the car is relatively inferior, so the engine may be frozen and cracked. In this case, the car's water pump will not work properly, which will cause the vehicle to not catch fire. In short, in colder areas, you should try to park your car in an underground parking lot or garage and avoid parking your car in the open air.

Because the battery will also be due to the low temperature environment, the storage energy will decrease, the starting voltage will drop due to the code wisdom type, and the low temperature will make the oil flow poor, the lubrication is not sufficient, the volatility of gasoline is not good, and the combustion is not sufficient, etc., will make it difficult to start the car.

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 do this 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 hot air from the front of the air intake into the cylinder.

Reasons why the car won't catch fire:

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

Engine starting difficulty means that the starter can drive the engine to rotate at normal speed, and there are obvious signs of landing, but it is difficult to start; Either you need to start it several times in a row, or turn the starter for a long time to start the engine.

1.The most direct impact of the low battery power on the family car in winter is the battery. At low temperatures, the car's power consumption will be significantly higher than in other seasons.

The capacity of the battery will also be reduced due to the low temperature environment. If the battery is used for a long time, the initial starting voltage will be low. For example, the adhesion of dirty oil on the surface of the battery will make the voltage output unstable and cause the body to shake.

This situation can be effectively avoided by replacing the battery with a new one or charging the battery in time.

2.When the throttle is started, the fuel is too thin and the fuel supply is not smooth, and the fuel will wet the spark plug, making it unable to start normally. This is because it flows into the cylinder in a liquid state, causing puddles to appear on the upper part of the cylinder piston.

As the piston runs up and down, fuel splashes on the electrodes of the spark plug, making it inoperable and unable to start. These conditions indicate that your car needs to be thoroughly serviced, and carbon deposits in the air intakes, throttle valves, and cylinders should be removed.

3.Frozen exhaust pipes or carbon deposits on the valves can also make engine start-up difficult. The exhaust pipe icing is mainly due to the low frequency of car use in winter, and the water vapor produced after the engine combustion freezes in a certain part of the exhaust pipe, but the ice cannot be melted after short-distance driving, and it will have an impact on the car start and exhaust for a long time.
