Do I need to warm up my car before driving in winter? Do you need a hot car to drive in winter?

1. It is best to warm up the car within 3 minutes before driving in winter.

2. Trivia Why is it best to warm up the car when driving in winter?

Warming up is to wait for a minute or two after the engine is started before driving, so that the engine and transmission can be warmed up.

1) The engine needs to get colder day by day, and if the car is not warmed, start the vehicle and drive away directly, which will cause great damage to the engine. Because the temperature is low in winter, and the normal operating temperature of the engine is around 90, this creates a huge temperature difference. If you drive directly on the road at this time, it will seriously affect the operation of the engine.

2) Insufficient lubrication of the running parts The pressure of the engine oil is not controlled by the computer, and the oil in the engine of the car flows back into the oil pan of the lower part of the engine after the car is parked overnight. Start the engine in the morning, the upper part of the engine is without oil, lack of lubrication, and the oil pressure is insufficient. When the car is started in the morning, a clicking sound is heard, which is the sound made when the oil pressure has not risen and the oil has not yet been delivered to the hydraulic tappet.

It takes about 30 seconds after the start of the oil pump to deliver the oil to the pistons, connecting rods and crankshafts of the engine, which need to be lubricated the most. Therefore, it is necessary to warm the car in situ before leaving the car in winter.

In winter, when the night temperature is low, the oil will become thicker and less fluid. In the morning, just start the car and immediately hit the accelerator and drive away, the cylinder wall has not formed an oil film, and the oil has not been sent to the various parts that need to be lubricated, which is easy to wear out the parts, and the service life will be damaged at the least, and the damage will be at worst.

3) Grasp the warm-up time, preferably within three minutes. Then you can drive slowly, but not too fast, so that you can ensure that the car is evenly warmed up without hurting the car, and the engine is well protected.

4) Don't rush to turn on the heater after getting in the car. In winter, many car owners are in a hurry to turn on the heater as soon as they get in the car, which is not right. The heat of the car heater comes from the waste heat of the engine, when just starting, the car is in the warm-up stage, not the normal working temperature, at this time turning on the heater will increase the circulation of cooling water, thereby increasing the warm-up time.

When the engine is running at low temperature for a long time, it will greatly increase fuel consumption due to the excessive concentration of mixed gas. Therefore, after getting into the car, the owner should not be in a hurry to use the heater, which not only consumes fuel, but also does not achieve the effect of heating.

5) It is best to warm the car in winter, which is considered by most people to extend the service life of their car; It doesn't matter if you are a local tyrant.

Do you need to warm up your car before driving in the winter? Here's how.

Some drivers often press the accelerator several times after starting the car, causing the engine to run rapidly. As everyone knows, this will cause great damage to the parts of the engine. Because when the engine starts (especially cold start), the working humidity of the engine is low, and the surface of the internal parts is not fully lubricated.

A good driving habit should be to warm up the engine after it starts, so that the engine coolant reaches the normal operating temperature (at least 50 or more) before progressing.

Driving in winter must be hot, the car is also a thing we often do, for example, when we want to do strenuous exercise, we have to warm up in advance is the same reason, so in the winter to take the car, because all parts of the car are not active, we warm up the car in advance will also make the engine and other components more flexible, especially now that the weather is particularly cold, some cars are often placed outdoors.

Then some internal parts will be in a very low temperature state, then before the car starts, the oil in the engine has also been cooled overnight, often falls on the engine, at this time the oil in the engine is also very viscous, we must heat the oil in the engine to evenly spread on the top of the engine, so that the use will be more flexible, and the engine will run to make our car more labor-saving.

Whether or not a hot car is needed in winter has always been a controversial topic. Many people are accustomed to hot cars in winter, and a hot car is a few minutes, and they feel that the car is frozen overnight, and sudden start will cause damage to the car. From time to time, when you see someone leaving as soon as you get in the car, you will think that this must be a novice.

So what is the most reasonable way to warm up the car?

Let's start with the principle of the car.

The main reason for a hot car is that after the car is parked for a long time, the oil in the engine flows back into the oil pan in the lower part of the engine. Therefore, after ignition, the upper part of the engine is in a state of lack of lubrication without oil, and it is about 30 seconds after starting that the oil pump will be used to transport the oil to the pistons, connecting rods and crankshafts that need to be lubricated most in the engine.

When the car is hot at idle, the engine control will feel quite rough. When the engine is idling in place, many engine components are moving slightly, especially the electronic control link, which is more difficult to control, in fact, it increases its workload from another level! When the car is heated up at idle, the rate of carbon deposits is faster.

Because the engine is not moving, the combustion chamber and other places do not burn the oil and gas sufficiently, and it is natural that the engine will accumulate more carbon.

In fact, the correct way to warm up the car is very simple, after the car starts the automatic transmission model, 10 seconds! Manual transmission, 30 seconds! That's perfectly enough.

More often than not, what should be done is to warm up the car in the walking state, so that it has a protective effect on the engine! As long as the speed does not exceed 2200, the speed is not fast, so that the hot car can make the gasoline and gas in the engine combustion chamber fully burn, reducing the formation of carbon deposits!

In fact, ignition and walking on the car is not as harmful as people say, now with the improvement of the manufacturer's production technology, the oil from the vehicle start, to flow to the whole car, it is only 3-4 seconds. In addition, engine tests, in general, are -30! So, it doesn't exist at all.

This is what the BMW 1 Series' vehicle manuals read.

Therefore, we can't keep the hot car in the idle state all the time. Using a car in this way is not beneficial and not conducive to environmental protection. As long as we maintain good driving habits, it is completely sufficient to follow the above methods.

Do you need a hot car to drive in winter?The right way to warm up the car, quickly see if you're wrong.

Motor vehicle. Cold. Stopped overnight. It's best to warm up the next day. It's only a matter of 2 minutes. Don't rush that 2 minutes. Because it's cold in winter. The oil will condense!

The car must be hot, the car is cold in winter, the oil and brake fluid are silk, and the big throttle directly does not heat the car to the engine is very damaging.

It is necessary in winter if the temperature is below minus 15 degrees. It can be maintained to get off the car (winter oil, brake pads, tires), etc.

You need to warm up your car before driving in winter.

In winter, the car needs to be warmed up before starting, because if there is no in-situ hot car, the lubricating oil can not reach the engine in time after the vehicle starts, and it is easy to wear out.

When the weather is particularly cold, the time of the original Heqing hot car does not need to be too long, generally about a minute, and then the owner can drive slowly for a few minutes, so that the effect of the hot car can also be achieved. Beating.

In addition, if the car is started in winter without in-situ heating, the engine will not be able to reach the temperature required for operation, and the fuel supply system will not be able to completely vaporize the gasoline due to the low temperature.

In this state, it is difficult to burn the gasoline and start the engine, and it is necessary to rely on the effect of the choke to prevent air from entering the cylinder, so that the engine stalls, in this case, the fuel consumption of the vehicle will increase, and there may be a lack of horsepower.

The right way to warm up in winter:

1. In winter, wait until the water temperature is normal to gradually accelerate. After the fire is lit, the car should wait in place, about 30 seconds to a minute, and when you see that the engine tachometer needle has dropped to 1200 rpm, if the vehicle is relatively stable if there is no obvious shaking, you can start in gear.

2. After starting, the engine speed should be maintained at 2000 rpm for about 3 5 minutes, at this time, the oil of the gearbox can be fully circulated, and the viscosity of the oil can gradually return to the normal value. When the pointer of the water temperature gauge turns to about 60 degrees, it can accelerate normally.

The temperature in winter is very low, the vehicle is placed overnight, the viscosity of the car oil increases, if the cold car starts immediately, the damage to the vehicle is very large, so the hot car in winter is more critical. So how to warm up the car properly in winter

A lot of people know about hot cars, but they don't understand why they need to warm up. In fact, the premise of a hot car is that the car is left for a long time, and the oil in the engine flows to the bottom of the engine.

Therefore, after ignition, the upper part of the engine is in the absence of automobile oil and no lubrication, and it is about 30 seconds after starting, before the automobile oil will be transported to the piston rod, crankshaft and engine crankshaft and other components that must be lubricated by the engine due to the operation of the fuel injection pump.

I don't know if you've noticed: When we run a car, we usually notice that the tachometer hand is at a point where it is more than twice the normal idle speed for a moment (especially in automatic cars). This is also when the car is ignited, the system automatic module (alias ECU) on the modern car is to let the oil pump system software spray more gasoline and diesel into the cylinder to increase the speed of the engine, so that it can quickly increase the temperature in the case of a cool car.

The level at which the speed of the cool car rises depends on the external operating temperature of each car and the ECU setting, and not every car will have the same speed value. After the vehicle is in operation, the grease is not available at idle time, so it is most susceptible to damage. According to statistics, more than 90% of the damage to engine parts is caused within three minutes after the cool car starts.

Hence the winter. Especially in the cold winter, it is very easy to damage the engine by idling in place, so it is recommended that the car buyer choose to heat the car by driving slowly at low rpm.

After running in winter, the temperature will be significantly lower than normal, and it will not be able to slowly increase until the temperature is normal. Ignite the car and wait still for a while (the waiting time is the time when the speed is reduced and the speed is relatively stable, generally no more than one minute). For example, when the vehicle just landed, the speed was above 2000 rpm, and after about 30 seconds and 1 minute, the engine tachometer hand was reduced to about 1200 rpm (but it had not been reduced to the normal idle speed of 800 1000 rpm), and it was basically stable without obvious ups and downs, and the car body did not have obvious flutter when you could start in gear.

It is necessary to warm up the car in advance. Because the weather is very cold in winter, the engine will also be affected, so it is necessary to warm up the car in advance so that it will not damage the engine.

Need. Because the weather is cold in winter, warming up the car in advance can reduce the occurrence of breakdowns, so it is necessary to warm up the car in advance.

Yes, be sure to warm up the car in advance, so that you can avoid mechanical failures and protect the engine well.

Today, I will talk to you about how to make your car warm and trendy in winter!

Skill 1Necessary warm-up time

Whether or not to warm the car is always a controversial topic, but from the perspective of maintenance, it is necessary to warm the car. People need a normal body temperature, and the car is no exception, but the car can't be called "body temperature", it's calledOperating temperature

Strictly speaking, the engine, transmission, and various moving parts all need the right operating temperature, but the engine is more sensitive to temperature. When the engine reaches the working temperature, the gap between the moving parts can reach a relatively ideal state, and the vaporization of fuel, the formation of mixture, ignition, and the fluidity and viscosity of the engine oil can reach the best state.

To put it simply, after the engine reaches the working temperature, it will run smoothly, make low noise, increase (x) speed (x) give (o) force (o), low fuel consumption, and ......... emissionsAll in all, it's very cool. (Generally, it is recommended that the hot car should not exceed 1 minute, and do not heat up the car in situ, you should step on the accelerator slowly, and you can drive normally after the water temperature rises.) ）

Whether it consumes electricity depends on whether it is automatic air or air conditioner heater. Automatic heater is the heat of the engine is blown into the car through air circulation, so it will not increase fuel consumption; If you turn on the air conditioner heater, because the air conditioning compressor is in working condition, it will naturally increase fuel consumption, so how will you choose?

Skill 3Tire maintenance should not be taken lightly

The low temperature and dry winter is easy to produce tire drying, which makes the rubber hard and relatively brittle, not only the friction coefficient will be reduced, but it is also more prone to air leakage and puncture. It is very necessary to check the condition of the tire frequently, clean up the inclusions in the tread, etc., especially when the tire is found to be more worn, it must be replaced in time! So, there's something to say:

A safe trip starts with tires!
