Do you need a hot car to drive in cold weather, do you need a hot car to drive in winter

The weather is cold and you definitely need a hot car, generally, it takes 2 to 3 minutes to warm the car, and I am very happy to help you

In winter, when the car is parked for a long time, the oil in the engine has been returned to the lower oil pan, and the upper half of the engine will be in a "dry grinding" condition due to lack of lubrication. That's why there is a saying about "hot cars". It takes about 30 seconds for the car to start, and the oil pump is running to send the oil to the pistons, connecting rods, and crankshafts that need lubrication the most.

Therefore, if you do not warm up the vehicle and go directly to the car, it will greatly reduce the life of the engine in the long run!

However, it is also not advisable to idle in place to warm up the car, because the fuel consumption of idling for 3 minutes is roughly equivalent to driving 1 km at a speed of 60 km/h. At the same time, because the temperature is not enough, the substances that need to be converted by the three-way catalytic converter will also increase, and the burden will become heavier, resulting in damage to the catalytic converter.

The correct answer is: after starting the engine to reach a stable and normal idle speed (generally no more than 1 minute), start 1st or 2nd gear, keep the speed within 2000 and drive slowly, and drive normally when the water temperature reaches 60 (generally more than one-third of the water temperature gauge)!

Yes, whether it is cold or hot, as long as the temperature is lower than 30 degrees, the engine of the car is started for the first time on the day, and the car needs to be warmed up (to raise the temperature of the engine). The function of the hot car is to increase the temperature of the engine itself, so that the lubricating oil has the best lubrication effect, reduce the wear and tear of the engine running parts, and improve the power of the engine. Because the best operating temperature of the engine is about 90 degrees Celsius, in order to save fuel and heat the car does not have to reach 90 degrees, the hot car can start driving when it reaches more than 50 degrees, and it can not drive rapidly at this time, and wait until the temperature reaches 90 degrees Celsius Normal water temperature can be accelerated.

In the north of our country, you need a hot car to drive in winter, and you can drive in a simple idle state in the south for a minute or two.

The technology of our current car is quite good, the period is very advanced, and the technical cost will be very high, so if you drive in cold, you don't need to heat up the car for too long, at most it is 30 seconds of the boom, and then walk slowly, because the damage to the car is also great if it is heated for a long time, and there are a lot of groups in the first place, so it is said that the car is slowly after playing. Just drive away, and when the water is warm, you can speed up.

A hot car is required, preferably three to five minutes after starting!

When the weather is cold, you don't need to warm up the car after starting in the morning, but don't step on the accelerator when you drive, and don't exceed 2000 rpm, just wait for the water temperature to come up.

I hope mine can help you.

In winter, you need to warm up the car when you start driving, and the time is about 3 minutes!

When the weather is cold, the car should be warmed up first, which is good for both the engine and the car.

After hitting **, step on the accelerator, look at the speed of the dashboard, after the speed is stable, the current car has been cold running-in before leaving the factory, the hot car is just to let the lubricating oil be thoroughly lubricated, and the hot car is not good for a long time, and carbon deposits will be formed.

It's best to warm up for two to three minutes. It's not necessarily good after a long time. It's good to have a smooth idling.

In winter, the outdoor temperature is too low, and it is necessary to warm up the car before driving the vehicle on the road, especially the engine with turbocharging, even in the summer, it needs to warm up the car for 1-2 minutes before you can drive on the road.

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.

It is best to warm up the car in the morning when it is cold, but pay attention to the method.

First, the reason for the hot car.

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. Therefore, when the engine is started after a long period of inactivity (e.g. overnight), the upper part of the engine is in a state of lack of oil and lubrication. 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.

2. Before the engine reaches the working temperature (about 90-110 degrees Celsius), its oil supply system cannot effectively vaporize the gasoline completely due to the low temperature (I believe everyone knows that the liquid temperature rises to the boiling point and is vaporized). In gasoline has not yet been vaporized"Wet"When it is liquid, it is not easy to burn and start the engine. At this time, it is necessary to rely on the effect of the choke to prevent part of the air from entering the cylinder, so as to improve the mixing ratio of gasoline and air, and increase the engine speed so that the engine does not stall.

When the normal working temperature is reached, the automatic choke will naturally return to its normal state due to the action of the machinery; And the manual choke car must remember to put the choke back, otherwise because the oil-gas mixing ratio is too high, not only waste gasoline, horsepower is insufficient, and gasoline combustion is not completely black smoke.

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. This is also the reason why most cars change gears jerkily when they are cold.

Second, the hot car method.

Do not idle the hot car in place. The correct way to warm up the car should be 30 seconds to one minute after starting. However, at this time, do not drive at high speeds, keep the speed at a low speed, and the engine speed should not exceed 3000 3500 rpm.

Generally keep 2000 rpm. Otherwise, the intense wear and tear on the engine and gearbox will not be restored. Wait for the engine temperature to rise to normal operating temperature before resuming"Personal habits"The driving method is sufficient.

1. In winter, because of the cold weather, all kinds of oil products are in a semi-solidified state without heat, which cannot play a good lubricating role, but will increase the resistance and increase the burden on the car.

2. Generally, the car heats up for about five minutes, and I usually light a cigarette and leave after smoking. Actually, it's not very good, the best way to warm up the car is to run slowly, but I'm not used to it, I'm still used to smoking a cigarette.

3. If the car is not hot in the short term, it will not be too much of a problem, if the car is not hot every time, it may cause aggravated gearbox wear, shortened life, difficult to hang gears, astringent steering wheel and other problems, and may even lead to vehicle failure.

Nowadays, the average car does not have a carburetor, and it is difficult to find it. Not to mention more than 200,000 cars. Now you don't have to idle for too long in winter, 2 or 3 minutes is enough, don't accelerate after getting up, and everything will be normal when the water temperature rises slightly.

In winter, it is also not recommended to turn on the heater when you get in the car, which will prolong the warm-up time of the car. Some friends like to warm up the car for a long time, and wait until the idle speed is normal to get started, which is not good for the EFI car, it will only increase pollution, time-consuming and fuel-consuming.

The first ignition in the morning must be hot, usually about 3 minutes, in winter to be longer, try to make the cool car idle into normal idling before starting.

Once you get up, slow down for a few minutes before driving normally.

Reasons for the hot car:

In winter, due to climatic conditions, the lubricating oil used is relatively thin, the parking time is too long, and the lubrication effect in the body is not good. Even other lubricants can condense when cold, which can lead to aggravated wear and tear on various parts of the car over time.

When the temperature is below zero, it's best to warm up the car in the morning before leaving, even if it's only for two minutes, it's better than just starting up.

The car must be started to be good, otherwise it will affect the brakes or something after a long time, just a few minutes, and love the car is to take care of your own life

The average car doesn't have a carburetor, and you don't have to idle for too long in winter, a few minutes is enough to accelerate quickly, and everything will be normal when the water temperature rises slightly.

In cold weather, you need to warm up the car, about 1 minute, don't take too long, it will consume fuel or carbon.

There is no need to preheat the relevant parts of the vehicle The precision is relatively high, the quality is good, the gap between the parts at high and low temperatures is not large, and the current oil lubrication performance is very high, so there is no need to preheat.

Need to warm up, about 1 minute.

Start the car, check the tires, open the hood, look at the water tank water, wiper water, oil dipstick.

It's been almost a minute.

The most effective way to warm up a car in winter can not only reduce carbon deposits, but also reduce fuel consumption!

If the temperature is not below -15 degrees, there is no need to heat up the car. In winter, remember to warm up the car in situ.

I'm waiting for the engine to start moving slowly at about 1000, and I'm at high speed when the water temperature comes up! The last time I saw it on Suzhou**, it said that the engine was starting to warm up first, and I didn't know what it meant!?

Me too, and it doesn't cost much oil in spring, autumn, winter or summer; Of course, I also take it for granted that I can protect the engine! When the water temperature rises, the acceleration process is much smoother than that of a cold car!

Yes, when the weather is cold, the engine of the car heats up more slowly, so it is necessary to warm up the car.

The correct way to "heat up" the car is not to idle and heat up the car on the spot as we usually do, which can easily cause insufficient combustion and generate carbon deposits. Only when driving at low speeds can the engine be optimally operational, thus protecting all parts from damage.

In fact, if the temperature is too high or too low, it will cause some damage to the engine, so there are many people who feel that they need to heat up the car in winter, because it is too cold in winter, the vehicle is placed outdoors for a long time, and the temperature of the engine will be very low. Veteran drivers may not be able to make the right judgment.

A hot car means not to refuel violently when starting the car, but to start slowly, let the oil in the engine and gearbox in the car circulate again, and wet the originally dry places, so that the engine will not be damaged when driving at speed. Some people like to heat up the car, but it is best to take 30 seconds to 1 minute, if the time is too long, it is easy to cause carbon deposit.

Under low temperature conditions, the oil pressure of the lubrication system does not support the viscous oil flow, it takes a certain amount of time to reach the lubrication conditions of normal driving, do not step on the accelerator immediately after starting, but should be powered on for about a minute, the low temperature conditions will make the electronic equipment disordered, waiting for the electronic equipment of the car to reach a stable condition can be carried out for the next gentle driving. In fact, there is no need to be too long and too nervous about hot cars, but it cannot be completely ignored, and it is good to pay a little attention when using the car, especially when it is almost winter, this hot car may seem more necessary.
