In winter, the car can not be driven away immediately after starting, and what needs to be paid atte

Before going out, turn on the car about 5 minutes in advance, and start it again after the car is warmed up. Don't hit the steering wheel too ice and snow roads, don't get too close to the car in front, and don't slam on the brakes. Don't stick too close to the curb. I don't know what kind of car you are?

If the car is in winter and does not start, you should first check whether the battery has electricity, and then check that the spark plug has carbon deposits and need to replace it.

You can choose some gasoline with a lower viscosity, or you can heat up the car first, or you can park the car in a warmer place.

Replace the special engine oil for winter, install the fuel injection pipe in the engine intake pipe for fuel injection, and preheat it by igniting the glowing plug, and install a heating wire in the engine intake pipe for preheating.

In this case, it must be caused by too low temperature, and at this time, professionals are needed to deal with it.

When the weather is cold, you must warm up the car before you can go, otherwise it will damage the car. In response to the topic of whether to warm up the car this winter, I will once again tell you a more practical view of using the car, hoping to solve your doubts. Because the weather is cold in winter, the oil flows back to the bottom when the car is parked overnight, and the temperature is low, and the performance of the oil in all aspects is definitely not as good as when the temperature is high.

So when the car starts cold, the idle speed of the car is definitely not as good as in summer.

According to the experience of driving in most parts of our country, of course, the Northeast region may be a bit special, and it may reach minus 20 degrees in winter. Most areas may hover around minus five or six degrees, which is not too bad for a car. As long as the oil used in the car is not a typical 10w15w summer oil, there is generally no need to deliberately heat the car.

Get in the car, take a taxi, and then use the car. After the fight, you will see that the initial velocity of the car is relatively high, and the speed may be shaky. Then the car will slowly heat up and the speed will start to drop.

You can take advantage of this time to get out of the car and check the tire pressure of the four tires, and then go to the back of the car to see if there are any factors affecting safety. After inspecting these safety facilities.

At this point, the car's tachometer is stable, and stabilizing within your car's idle range may be a little higher. As long as your tachometer isn't beating and is relatively stable, start the car and start moving slowly. When using the car in winter, as long as the temperature is not very bad and it is dozens of degrees below zero, there is basically no need to deliberately idle the car for a long time.

After taking a taxi, you can check the safety equipment and drive slowly. Just note that don't use the car too vigorously until the engine water temperature comes up. For example, refueling, braking, and pulling hard, and then pulling the speed according to normal conditions, running 34560 cars to the city is not a big problem.

Before we say whether we want to warm the car or not, we need to know one thing, that is, where did the word "warm car" come from? Why is there such a sentence that you need to warm up your car before driving in winter? In fact, this issue has already been mentioned at the beginning.

Hot cars originated in the era when cars were equipped with carburetor technology.

Carburetor technology was basically used in previous car engines. Due to its structural and technical limitations, when the temperature is low, the fuel cannot be atomized and diluted well, which will cause the fuel to be unstable, which in turn will lead to idle instability and throttle nonlinearity. So to solve this problem, the term hot car is used.

Due to the low winter temperatures, especially in the Tohoku region, the temperature even reaches -20 or -30. When the car is cold, the carburetor often does not work properly, and the control of fuel injection is very unstable, resulting in the unstable operation of the vehicle engine. In order to solve this problem, some masters think of hot cars, but they are actually waiting for the carburetor to reach the normal working temperature, so that the oil supply system can work stably.

Need a hot car. Because the temperature is low in winter, the car cannot be started, so it needs to be warmed up.

In fact, there is no need to heat up the car in situ before driving in winter, and the most correct way to warm up the car is to start the engine and then go in gear, but don't let the engine run at too high speed when you just start driving.

Of course, a hot car is needed, and only a hot car can better maintain the performance of the whole car. It can also reduce the corresponding hazards.

1. The car needs to be warmed up before driving.

After a cold night, the oil has flowed into the oil pan, but the oil cannot be transported through the oil pump to the pistons where the engine needs to be lubricated the most, so it is necessary to warm up the engine.

The hot train should not take more than 1 minute, and the best time is between 30 seconds and 1 minute. Slow down the accelerator when driving on the road, and drive normally when the water temperature rises.

2. Ensure that the windows are defogged in time.

In the case of fogging in the car, you can use the air conditioner to defog it. It should be noted that the fog in the car will become larger when the hot air is just turned on, because the temperature difference between the inside and outside is greater, and the fog will disappear after the hot air dries the moisture in the car.

3. Reasonable use of gears.

Many automatic transmissions now have a snow mode that allows you to switch to snow mode when driving in snowy conditions. For manual transmission models, it is recommended to start in 2nd gear in snowy days to ensure a certain torque output and reduce the probability of tire slippage.

Precautions for driving in winter:

1. Keep the distance and speed of the vehicle.

Driving on ice and snow roads is first of all slow, followed by keeping enough distance from the car in front, and braking in advance, when you find that the distance between you and the car in front is shortening, you must immediately collect the oil and slow down and put your foot on the brake pedal to prepare for braking.

When braking, you can quickly downshift the brakes, but it is absolutely strictly forbidden to remove the brakes, and the effect of engine deceleration is definitely much more effective and safe than braking on ice.

2. Hit the direction slowly and step on the brakes slowly.

When passing or driving on ice and snow roads, the steering should be gentle, and do not blindly hit the direction sharply, which will cause the vehicle to lose control and cause danger.

In addition, because the road surface is easy to freeze when it is cold, if there is snow or ice on the road, do not brake suddenly, and use the gear position reasonably to control the speed.

3. Turn on the heater and don't overheat.

Due to the low temperature in winter, it is very common to turn on the heater when driving, it is recommended that the owner of the car when driving in winter, especially in the afternoon or at night, try not to turn on the heater too much, the car is too warm and easy to get sleepy and cause potential safety hazards, and the temperature difference between inside and outside the car is also easy to cause colds, the heater is turned on to the appropriate temperature, not cold.

Winter start-up should be noted:

Before starting, you should turn on the ignition switch and wait for about 5 seconds to let the oil pump work before starting.

It is best to turn on electrical equipment such as lights and radios after starting the engine to work. Before stopping, turn off these power-hungry appliances and then turn off the engine.

Just don't fail to start the first time, and then ...... the second and third timesIn fact, this 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 speeds after the car starts, but give the vehicle a warm-up time, so that the vehicle is not easy to wear out and can improve fuel economy.

Generally, the water temperature of the vehicle should be at least 40 degrees Celsius or higher before starting to drive.

It is best to turn on the heater 15 minutes after the car starts or about 3 km, because this is when the engine is working properly.

For manual transmission models, check whether the gear has been placed in neutral gear before starting, so as to avoid damage to the starting motor or vehicle channeling caused by starting with gear. When the vehicle starts, it needs to rely on the power of the battery to drive the starting motor and then drive the engine, the battery at this time needs to output a large current, and it is also the moment when the battery consumes the most in the whole working cycle, so before starting, the lights, audio, air conditioning and other large electrical appliances on the car should be turned off as much as possible to ensure that the power of the battery can be completely exported to the starter. This is not only a protection for the battery, but also a necessity to make the starter work easier.

After getting into the car, insert the key into the key door, don't start the vehicle in a hurry, you should first screw the key door to the position where the power is turned on, at this time all the warning lights on the dashboard will be lit, carry out vehicle self-inspection, after most of the warning lights are extinguished, it means that the system self-test is completed (at this time, there should be only three warning lights that are normally lit, battery warning lights, handbrake lights and seat belt warning lights), at this time you can twist the key to the "start" gear and start the engine.

Is it necessary to warm up the car when starting the cold car, especially in the cold winter season, and what is the correct way to warm the car? Although most of them are EFI trucks nowadays, it is easier to drive and drive when the car is not hot, but it hurts the car very much when driving cold for a long time. Driving a cold car can cause the car's engine to undergo an overhaul sooner.

Therefore, the owner must have the awareness of hot cars.

30 seconds for the oil to be able"Stream in place"

After the car has been parked for a long time, the oil in the engine flows back into the oil pan in the lower part of the engine. Therefore, if the car is not used for a long time, such as starting the engine after overnight, there is no oil in the upper part of the engine, and it is in a state of lack of lubrication. It takes about 30 seconds after the start of the oil pump to transport the oil to the pistons, connecting rods and crankshafts that need the most lubrication of the engine.

90 degrees, gasoline can be atomized.

Before the engine reaches operating temperature (approximately 90 110 degrees Celsius), the fuel supply system is not able to effectively atomize the gasoline completely due to the low temperature. If it is started directly, it is easy to cause part of the gasoline to flow back to the oil tank due to the inability to atomize quickly, resulting in oil deterioration. It takes seven or eight minutes to ten minutes for the cold engine to reach the normal operating temperature, but during this time, there is no need to heat the car in place, as long as it is not driven at high speeds.

The more correct method of warming up the car should be, on the road after starting 1 2 minutes, if it is particularly cold, you can add a minute or two, wait for the water temperature gauge to change slightly before driving on the road, before the water temperature reaches the normal value, remember not to drive at high speed and high speed, and should make the engine water temperature reach the normal value in low-speed driving, and then resume normal driving.

Do not turn on the heater when fuel-saving and hot up in winter.

Many people like to turn on the heater when driving in winter, thinking that blowing the hot air of the engine is different from turning on the air conditioner and will not increase fuel consumption. Blowing hot air also consumes fuel, but it doesn't consume as much fuel as turning on an air conditioner in the summer. In winter, instead of using a compressor, the heater is heated by the coolant temperature of the engine, which blows the heat released by the engine itself into the cabin through the blower.

Although the operation of the blower requires electricity, which increases the load on the engine and thus consumes fuel, it is far less than the fuel consumption when the air conditioner is turned on in the summer.

In cold weather, the vehicle heats up in situ for about a minute or two before starting to improve the overall performance of the engine.

Hot car, must, regardless of the good car general car, hot for a minute, if not far on the road is high-speed, fast loop, then hot for a few more minutes, so that the engine is good, the life of the car will be longer.

After the hot car, step on the brakes and clutch a few times, because it is cold in winter, the surface of the clutch pads and brake pads will be attached to the water vapor in the morning, if you don't pay attention, it will cause the clutch or brake to slip, which is very dangerous.

There's nothing special to pay attention to, it's basically the same as in the summer.

Because today's cars are electronically controlled, at low temperatures, the engine computer will automatically increase the amount of fuel injected into the engine.

If you have to pay attention, it is best not to start the car frequently and repeatedly to prevent the car battery from being damaged.

When you start it, you should warm up the car first and wait for the oil circuit to be in place before opening, generally 30 seconds.
