How to heat up the car correctly, how to warm up the car correctly

In winter, the car must be warmed up first, because after the car is parked for a long time, when it is started again, the upper part of the engine is in a state of no oil, and at the same time, the engine does not reach the working temperature, and the gasoline cannot be effectively burned completely due to the low temperature of the machine. If you drive with fuel at this time, it will cause wear and tear on pistons, cylinders, etc.

Good morning, most of the oil viscosity is too large when the car starts in winter, and the lubrication is not good for a short time, so it will increase the wear and tear of the engine in the early stage of starting, and it is best to idle the car in situ for 2 minutes until the water temperature is normal, and then drive normally, too low or too high water temperature will increase the wear and tear of the engine and increase fuel consumption.

Hello Generally, in winter, it is okay to warm up the car in about a minute or two, and it is not good to idle for a long time.

Generally, it is recommended that the in-situ hot car should not take more than one minute, and then drive slowly on the road. Until the water temperature is normal, it's fine.

Warm up the car in situ for a minute, then drive at a low speed, wait for the temperature to come up and then drive normally.

Hello, after the vehicle starts, the engine idles for 1 to 3 minutes, and when the water temperature of the engine starts to rise, it can start normally.

Hello, there is a very good way to warm up the car, now the car technology is very mature, you only need to idle for a few minutes to start, do not accelerate sharply during the period, you can rest assured that you can drive, not only will not damage the engine, but also save fuel costs, you can also warm up the car, I hope to help you, I wish you a happy car.

Under normal circumstances, if the weather is relatively cold. After the car is started, it will be better to warm up the car for two to three minutes before driving, which will be better for the engine.

If the cold car starts, the speed will be relatively high, and when he returns to normal, he can walk slowly, walk slowly at first, not more than 2,000 rpm, and then you can drive normally after the temperature comes up.

Hello, this current car is generally in situ hot car for about 1 minute, and then slow on the road, and when the water temperature is normal, you can drive normally.

Hello! Get on the car normally, and after starting, the engine speed is 1000 rpm, and you can drive normally without problems.

Hello, after the engine of the vehicle is started cold, the engine computer will control the engine to run at high idle speed, in order to warm up the engine faster. Wait until the vehicle's engine idle speed is back to normal and you can drive!

Hello, generally after igniting the engine in the same place to warm up for dozens of seconds can be on the road normally, at the beginning of low speed slow waiting for the water temperature to come up some can be accelerated.

If the temperature is too low, you need to warm up the car for two minutes and then drive slowly for a while. When the temperature rises, you can drive with confidence!

Hello, this hot car, idle in place for no more than one minute, and then drive at low speed, and you can drive normally after the water temperature is normal.

Hello, the cold car is on fire and waits for the idle speed to drop smoothly before driving, and it is not recommended to drive at high speed before the water temperature rises.

Today's cars basically don't need to be cared on, and some may be needed in winter, but the performance of the cars is relatively good.

Generally speaking, it can idle in place for about a minute or drive at low speed, which can also achieve an effect of hot car.

You need to idle in place for 30 seconds to a minute. Then drive slowly, one to 2 km and wait for the water temperature to rise.

Hello, under normal circumstances, generally in the morning, use cold idling to drive, do not heat the car in situ will cause damage to the three-way catalytic converter.

<> "How to Warm Up a Car Properly? Remember this practice and warm up the car reasonably.

Do you want to warm up the car in winter? What is the right way to do it? Some people on the Internet say that you have to wait for the water temperature to be normal before you can drive, otherwise it will cause abnormal wear and tear to the engine, and some people say that it will be hot for 10 seconds or 30 seconds, and you can drive it casually.

For our novice friends, it is confusing to see which hail disturbance method, and I don't dare to try it easily, in case the car is broken, it is still myself who suffers, and others are not back hurting when they stand and talk, right?

I've tried two completely different ways to warm up the car, and the previous one that I sold was completely the textbook hot car in place. It's like we drive a motorcycle in the winter, start the car in advance, and then throw it there for a few minutes and slap the accelerator from time to time.

I felt that these few feet of throttle could blow the engine smoothly before I started to use the car, but I only sold this car after 30,000 kilometers. The reason for selling it is very simple, the noise is too loud when driving at low speed in 1st gear and 2nd gear, and the start is getting more and more meaty, and the clutch is not much loose, it is suffocated, and the fuel consumption of the vehicle is getting bigger and bigger, I can't accept it.

For a long time, I didn't understand why my car was like this, and then I realized that I knew a little bit about the car, and the fuel consumption was getting bigger and bigger, and the phenomenon of weak power and detonation was not the main manifestation of more carbon deposits. Why is there a lot of carbon deposit? I would be a novice, all refueling at regular gas stations, and the oil is no problem, so it can only be said that my car habits have caused carbon deposits to become more and more serious.

I doubt that it is caused by my hot car habits, so after buying a new car, I will no longer be as hot as before, simply I will not warm the car, Yuan Huaidan started the car and waited for 10 or 20 seconds to use the car. But I don't dare to accelerate sharply before the water temperature of the engine is normal, I have always used the car and slowly wait for the water temperature to be normal before accelerating normally.

Up to now, my Vios car, which has not been very deliberately hot-up, has run 100,000 kilometers, although I don't deliberately pick a gas station, but I often refuel at a regular gas station, and the engine oil used is also fully synthetic. At present, although the fuel consumption of this car is not as economical as that of the new car, it will not be like the old car before, and it will become more and more chaotic and direct to the point that I can't accept it.

The power is still strong and there is no problem of low speed gear noise, after such a comparison, I think it is not necessary or even advisable to heat up the car in situ, but to heat it for 10 or 20 seconds to use the car and wait for the water temperature to be normal and then accelerate normally is a hot car mode that I think is better and more correct.

The standard method of hot car is: 1. The temperature is 0, and the idle hot car for 60 seconds is the standard time standard thick chain. The temperature rises to 1 for a while, and the time for heating the car at idle drops and rises for a while.

2. Start one minute and then hit the road. In this case, it is absolutely not possible to run at high speeds. Vehicles must maintain a low speed.

Engine speed is limited to less than 3,000 cycles, and most of them must be maintained at 2,000 revolutions before the engine and transmission are subjected to severe wear and tear to recover. 3. A hot car is not only a hot engine, but also a transmission for the same reason. The transmission consists of gears immersed in the transmission oil, and the only way to increase the temperature inside the transmission is to rely on the friction of the rock return gears and the flow of oil.

4. The temperature of the transmission that has just started is low, which is not suitable for high-torque and high-speed operation. Run slowly for a period of time, and only after the engine and transmission oil temperature are normal can you run with high torque and high speed.

The correct way to warm up the car is to hit the road 30 seconds to one minute after starting, but at this time you should keep the speed low, wait for the engine temperature to rise to normal operating temperature (it will take about 3 to 5 minutes), and then resume normal driving.

When starting the car, it is often found that the tachometer hand is more than double the normal idle speed at the moment of the start (especially in automatic transmissions). This is when the car is ignited, the computer automatic control module on the Hyundai sedan is injecting more fuel into the cylinder to increase the speed of the engine, so that it can quickly heat up in the cold state.

As for the degree to which the speed of the cold car increases, it depends on the external ambient temperature of each car and the ECU settings, and not every car will have the same speed value. Under normal circumstances, the engine speed will drop significantly within one minute of starting the cold car.

Warm up cars are needed in both summer and winter, and the warm-up time in winter is longer than in summer. After a night of static use of the engine, the lubricating oil on each friction surface has basically disappeared, and the oil film protection has been lost; The low temperature increases the viscosity of the lubricant, resulting in poor adhesion and flowability, which increases the resistance of the engine when it starts. Driving at this time will increase the load on the engine and increase unnecessary wear.

Causes of hot cars

1. After the car is parked for a long time, the oil in the engine flows back into the oil pan at the bottom of the engine.

2. Before the operating temperature (about 90-110 degrees Celsius), the fuel supply system of the nuclear engine of the introduction section cannot effectively vaporize the gasoline completely due to the low temperature. When the gasoline has not yet vaporized and is in the form of a wet liquid, it is not easy to burn and start the engine.

3. Regarding the lubrication of gearbox gears, this is the most ununderstood and easily ignored by ordinary people. Transmission gear oil is the same as engine oil: it flows to the bottom half of the transmission during cold driving.

Only when driving will the bottom gear oil be lifted up due to the operation of the gears and the upper part will be lubricated.

The correct way to warm up the car should be to hit the road 30 seconds to one minute after starting, but at this time do not drive at high speed, should keep at a low speed, engine speed is limited to no more than 3000 3500 rpm, generally maintain 2000 rpm.

Otherwise, the engine and gearbox will not be able to recover from the intense wear and tear they have suffered. Wait for the engine temperature to rise to normal operating temperature (about 3 to 5 minutes) and then resume normal driving.

In winter, when the temperature drops, it is necessary to warm up the car to tremble, but most car owners think that it is best to use the car early in the morning or for a long time, start the car, heat the car in place at idle speed, and wait for three or five minutes before hitting the road.

According to statistics, more than 90% of the wear and tear of engine parts is caused within three minutes of starting a cold car. Therefore, in winter, especially in the severe cold winter, it is easy to damage the engine by idling in place to warm up the car, so it is recommended that the owner use the method of driving slowly at low rpm to warm up the car.

Benefits of a hot car::

1. Improve the problem of three-way catalytic converter and improve emissions

Automobile exhaust emissions mainly rely on the three-way catalytic converter to purify, so that its harmful substances are reduced to a reasonable level, but the rare metals on the surface of the three-way catalytic converter need to work at a certain temperature to be able to produce an effect, and when the car is started, the temperature is obviously not enough, and the exhaust emissions in a short period of time are also exceeded, and if the car is hot, the total amount of exhaust emissions can be reduced to a certain extent.

2. Reduce the speed of the engine

The engine speed will be significantly higher than the normal idle speed in the starting stage of the car, and after a period of time, it will fall back to the normal level, resulting in this situation, mainly because the car is controlling the pure blue engine, in the shortest possible time, Huiqiao reaches the normal state, which can also reduce the waiting or starting time.

The correct way to warm up the car is as follows

After lighting the car, wait in place for a while (the waiting time depends on the relatively stable time after the rpm drops, usually no more than a minute). The stool is looking at the engine tachometer pointer down and basically stable without obvious fluctuations, and the body has no obvious shaking, in this case, you can start in gear.

Don't go too fast while driving, and keep the rpm at about 2000 rpm. Maintain the speed for 3-5 minutes, and the water temperature can accelerate normally when the water temperature reaches 60. Due to the long period of parking, the oil in the engine flows back under the engine.

Is it necessary to warm up the car.

For EFI engines, hot cars are completely unnecessary. The previous carburetor engine needed to be hot in situ, and the carburetor engine would have difficulty starting in winter, but now the EFI engine does not need to be hot in situ at all, and as long as there is no problem with the battery, the engine will not have difficulty starting in winter.

Heating a car in situ is just a waste of gas, and it doesn't do any good or even harm to the car. A few seconds after the engine starts, the oil will quickly reach the position where it needs to be lubricated and form an oil film, and the insufficient combustion of gasoline during in-situ heating will also increase the carbon deposit in the engine, and the pollutants in the exhaust will exceed the standard when the in-situ heating car is in place.

The correct way to warm up the car is to take the air temperature of 0 degrees Celsius and idle the car in place for 60 seconds as the standard time. The temperature increases or decreases by 1 degree Celsius, and the idle in-situ hot car time decreases or increases by 1 second.

On the road one minute after starting, do not drive at high speed, should keep the speed low, the engine speed is limited to no more than 3000 rpm, generally maintain 2000 rpm, otherwise the engine and gearbox are subject to intense wear and tear can not be recovered. A hot car is not only a hot engine, but also a gearbox. The gearbox is made up of gears soaked in the transmission oil, and the only way to increase the internal temperature of the gearbox is to rely on the friction of the gears and the flow of oil.

The temperature of the gearbox at the beginning is low, which is not suitable for high-torque and high-speed operation, and can travel slowly for a certain distance, waiting for the engine and transmission oil temperature to become normal before running at high torque and high speed.
