How to warm up the car in cold weather?
The onset of cold weather is always accompanied by additional costs and a bunch of minor troubles. In addition to buying winter tires, changing the oil and purchasing a new battery, you have to get up much earlier to start your car. During working hours, if the car is in the immediate vicinity of the office, it is possible, without leaving the office, using your key fob to start your car in advance. In the morning, or after a long stop, you have to wait some more time until the engine starts to reach the required temperature. But is it important to wait until the engine starts to heat up? And is it harmful to warm the engine in the cold at idle? We will try to understand these issues, because there is no single answer. Even experts do not have a common opinion on this subject..
Most operating instructions for modern cars say that you do not need to warm up the car before driving – oil and other liquids evenly warm up when driving at low speeds, without harming the car. However, servicemen warn that this advice does not apply to operation in cold weather. “There are several reasons to warm the car for 5-10 minutes while you clean the snow. Firstly, completely frozen gums will be covered with microcracks, if you do not let them thaw. Secondly, the liquids thicken in the cold, and it is better to give the engine oil and a little liquefy in the gearbox.
The concept of “engine warming up” dates back to the middle of the last century. The fact is that the cars of that time did not budge until the engine warms up to a certain temperature. In this case, the engine warmed up at idle. To avoid failures and the slightest possibility of stopping the engine, the motorist has to wait a certain time so that the engine warms up to at least the minimum temperature.
Only after warming up, you can move off without fear that the engine will stall. Modern cars are not so sensitive to temperature drops. In order to start moving after a long stop, it is enough to wait 1-2 minutes until the engine warms up, working at idle. But the answer to the question “to warm or not to warm the engine, and is it harmful to warm the engine in cold weather at idle?” we have not yet found.
Manufacturers of foreign cars recommend warming up the engine on the go. What is the reason for such an instruction? First of all, it is connected with the protection of the environment. When the engine is idling, a significant increase in fuel consumption occurs. The operation of the engine in heating mode leads to the emission of exhaust gases with a high content of harmful compounds.
But there is a certain list of conditions under which it is possible to start moving without waiting for the engine to reach operating temperature. These conditions do not in any way lead to a reduction in the operating life, otherwise manufacturers would not recommend such actions. After all, manufacturers are not interested in a quick breakdown of parts, since the warranty period is valid, and the reputation of manufacturers is also expensive. Their profit depends on demand.
The engine idling entails the rapid ignition of the air – fuel mixture, and this leads to engine pollution. When the engine heats up during movement, it heats up to the required temperature faster, and the operating time in extreme conditions is significantly reduced.
If you decide not to warm the engine at idle in the cold, then you need to observe some rules that you need to skillfully apply when warming up the car on the go.
The use of expensive synthetic oil.
Car warming up on the move is carried out only on condition of using oil filled into the engine with a high viscosity index. If the oil does not retain its fluidity, then when the engine is not heated, it will not be able to fill the necessary channels in the shortest possible time. This, in turn, is fraught with the formation of scoring on the working surface. In any mode of engine operation, rapid aging of the oil occurs. In winter, it is recommended to use expensive and high-quality oil, since in winter the oil is more quickly activated and turns into an aggressive liquid. This adversely affects the condition and operation of the engine..
Smooth movement, no jerking.
The engine warms up to a minimum temperature (+ 400C) in a fairly short period of time. This interval is enough to leave the garage or parking lot. It is advisable to pass this small path at a low speed, while maintaining stable engine operation at medium speeds.
Also, one should not accelerate sharply or slow down. This leaves a negative imprint not only on the engine, but also on the operation and condition of the chassis and gearbox assemblies. A sharp change in mode when the engine is not warmed up leads to accelerated wear of the mating parts and the working fluid. The fact is that the mating parts need some time for the thermal clearances to fully return to normal. With a sharp change in modes and aggressive driving with an engine not warmed up, the oil consumption noticeably increases. Also, this driving style can lead to the occurrence of piston rings. Winter conditions also negatively affect the running gear, and more specifically, the hydraulic elements (shock absorbers and steering racks). The fluid inside the hydraulic units must warm up to a certain temperature. Only after warming up is it possible to operate the hydraulic components in full force. After a long parking of the car, after starting the engine, it is necessary to move carefully at a distance of about one kilometer, bypassing potholes on the roadway.
Cars with turbo-diesel engines installed are not recommended to warm up on the go..
It’s all about the turbine. Its inclusion is possible only at the required speed of the crankshaft. This frequency occurs at a fairly high speed. As mentioned above, on an unheated engine, one should not develop high speed, but it is necessary to move at low speed for some time. Driving on a car with a diesel engine while the turbine is idle will lead to rapid overheating of the engine, which will entail a local overheating of the cylinder head and its warping.
Do not warm up a car with a carburetor engine on the go.
It is believed that the carburetor engine cannot be heated on the fly, since its normal operation is achieved only at a certain heating temperature. But it is not so. If the carburetor and ignition system are in good condition, the number of revolutions can be adjusted by means of an air damper. At the same time, the car will move without failures in 2-3 minutes. After such adjustment, a large amount of fuel will enter the engine, which will flush the oil from the piston surface. As a result, dry friction will occur between the rings and the cylinder, which will lead to scoring. From this we can conclude: the carburetor engine is still impractical to warm up on the go. It is better to warm up the engine in a stationary state at medium speeds and periodically adjust the air supply.
Also important is the question of comfort. If the street is cold, and the car has stood in the parking lot for a long time, then the cabin will be unbearably cold and driving in such conditions is simply unbearable. So without warming up the car in our climate zone just can not do.
Even the advanced technologies in the production of engines and lubricants do not allow the car owner to refuse to warm the engine in severe frost. Which way you will warm up is up to you. But it’s worthwhile to calculate the time required to warm up the engine, taking into account its condition, the quality of the oil used and the availability of time.

Comments:I warm up while I clean the glass from frost or snow. The stove works a second after starting the engine, a jet to the windshield.
Then 1-2 km. at speeds not higher than 2000. then – as usual

I warm up the car for about 5 minutes, and with the TURNER ON, blowing it onto the glass, otherwise with a CUTTING supply of hot air to the Cold glass, the last will CRACK and SPLIT ! ! !

Golf car 4, with the stove turned off, I warm the little car up to 70-80 and incl. the stove, I start moving and I don’t drive more than 60 km / h for 15-20 minutes (you can’t squeeze out more traffic jams in the city), the car is completely warming up and the heat is also inside.

dipped for at least 1 minute, max 2
then turn off everything at the same time, twist the starter for 4-5 seconds, if it does not start, wait 1-2 minutes (everything is off), the second attempt is 1-2 turns and everything starts up fine (up to -25 helps, checked) as an option to take home the acc -r, if the warm one does not start, either acc-r change either the car to the service, well, or a launcher, tie, light a cigarette)))

I warm up the engine in this order. I start the engine, turn on the stove immediately to the second speed, close the street damper so that the air warms up faster in the cabin. Engine turns fall within 10 minutes. I sit in the car, open the damper street, turn on the first speed and move to the first two, three minutes, then I switch to the second I’m moving. As the vehicle moves, it heats up quickly.

I’m warming up. For I want to go warm. So that the hands from the steering wheel do not freeze and the windows do not sweat. Actually, the algorithm – while the glass is heating up – until the suction cup of the DVR can be attached, the interior heats up, the deflectors on the steering wheel and on the windshield. At this time, if necessary, snow is swept away. Then you move the valve to the position – legs – and you are already driving quite comfortably. Not so the engine needs to warm up and it is important how the driver and passengers do not freeze 🙂
Sometimes, to make the engine warmer to 60 degrees faster and a little bit more gas, you can :), but without fanaticism. But in principle – according to the manual – the temperature is 60, the speed is 800 and you can go 🙂

in general, it is not very useful for glass when suddenly warm air begins to blow on it. It’s better to start it – immediately flow to the glass so that it slowly warms up. It’s like boiling eggs – you can’t boil it right away, you need to bring it to cold water and bring it to a boil.

I have been driving turbodiesels for a long time and decided for myself the following:
from -5 to -15 I bask in idle minutes 2-4 and go.
Below -15 I have the following algorithm:
It takes about half an hour to these dances with a tambourine. If you go or bask with the stove on, the temperature set up to 90 can last an hour or more.
