At the end of this and the beginning of next week, forecasters promise the first night frosts, and daytime temperatures will approach zero. This means that it will become cool not only for us, but also for the engine. Most motorists of the XXI century may be surprised at the very formulation of the question. Why warm up? Sat down, started and drove off. After all, so directly stated in the instructions of all modern machines... Who can you trust if not the manufacturer?
Just think: what is the car manufacturer interested in? The days when the answer to this question was "reliability and long-term operation" are long gone. Now, in the age of disposable items and the era of consumption, concerns encourage you to change your car as soon as possible and come to the salon for a new one. And what could be a better incentive than the feeling that your current transport is about to fall apart or expose you to expensive repairs? This would be a losing strategy, if not for one caveat: all industry giants have been adhering to it for 15 years now.
So you shouldn't believe in the care of the manufacturer. Besides the economic benefits, it follows environmental pressure. In the first minutes after a cold start, when catalytic converter not yet warmed up, the exhaust of even the most modern engine extremely "dirty". On the move, the engine and exhaust gas treatment system reach operating temperature faster than standing still. Hence the recommendation to immediately get under way. In addition, stand and give your exhaust the whole yard apartment building(and many of us keep the car in the yard), to put it mildly, impolite. But here we can advise you to slowly crawl out onto idle outside and "warm up" there.
In about many fresh models there is no dial gauge for the level of engine warm-up, only control lamps"Cold" and "hot". But the dial itself does not give a complete picture. It reflects the temperature of the coolant, which is gaining degrees quickly enough. Iron - the head, cylinders and pistons - do it a little slower.
But the oil in the crankcase lags behind. But the lubrication of the rubbing parts and, therefore, the degree of wear of the motor directly depends on it! The oil temperature gauge can be found on models of the PSA alliance of previous years, it is available to owners of non-standard on-board computers and sewn into the menu of complex multimedia systems expensive cars... But still, not everyone has it. To understand in what state the lubricant starts to work, do not skimp on a liter of the kind that is poured into your engine and leave it in the trunk over a winter night. In the morning, the fluidity of the oil will be very different from what you are used to seeing. So think about whether such a consistency can provide full lubrication of parts immediately after launch.
Thus, even the arrow of the antifreeze indicator that has moved from the bottom point does not guarantee that power unit completely ready to work at any speed. On the other hand, heating while standing in one place is now ineffective. Previous carburetor engines not only can it be brought up to the required 90 degrees in the parking lot, but even necessary. "Zhiguli", "Muscovites" and "Volga" often stubbornly refused to go without full warming up. The injection motor is not so picky and is ready to drive the car entrusted to it right away. And on the spot it can be "boiled" for a very long time. Diesel will not warm up at all, but gasoline unit reluctantly gains degrees, even in a sluggish traffic jam. So you still have to go, even if you want to act in the old-fashioned way: standing still won't give you anything, in motion the engine will reach operating temperature faster. But you need to step on the gas gently, without undue enthusiasm. Abrupt starts are already open violence against a cold engine.
In general, the recipe for warming up the engine is as follows. After starting a cold engine, you need to stand still for a while. How much is "a little"? Depends on the outside air temperature. Now it is enough to wait a minute until the oil is dispersed throughout the entire unit. With an average "minus" it is worth standing still for 3-4 minutes, and in a strong frost - one and a half to two times longer. Do not think that this is too long. Firstly, by doing this you will prolong the life of the engine (since it cannot be completely protected from cold starts). Secondly, the driver will have something to do for this period. The same minute will be spent on snapping the belt and viewing traffic jams on your smartphone. In winter, you will have to clean the car of snow, check if the wiper blades are frozen, and top up the anti-freeze. After all, the fight against smoking is far from over. So while away the time for your favorite process, standing still, and not being distracted from driving.
And further. Engine materials and oils have stepped forward for more than a century of the car's history. But the laws of physics remain the same. Parts rubbing against each other wear out at a colossal rate. Add to this the conscious commitment of automakers to reduce the life of their products. We think the answer to the question about the need for warming up after that will become obvious.
A frequently asked question from car owners in winter is to warm up or not to warm up the engine. At the same time, people broke up into two camps and each of them says whether it is worth warming up, while others are not. In the days of the USSR, when everyone had domestic carburetor cars "Zhiguli", "Volga", "Muscovites" there was no such question and everyone was warming up the engine in winter. And now, when foreign cars have appeared, in technical instructions began to write that it is possible not to warm up the car. You can start the engine and drive slowly. In this connection, the question arises whether to warm up or not to warm up the engine in winter, and the auto instructor Mikhail Dubatovk will tell you about this.
You may have heard that in European countries cars do not warm up in winter, but immediately start to drive slowly. In these countries, there is a struggle for the environment, but nowhere is it precisely spelled out in the law that the engine should not be warmed up in winter. To refer to the fact that the engine is not heated abroad is not an argument.
There is also such a category of people who refers to the fact that they do not heat the engine due to saving money. If I don't warm up the engine for five years, how much money can I save. The question is how the car will behave if the engine is not warmed up and how it will behave on the road. By saving money on warm-up, you can be sure that your engine, gearbox or chassis will function properly for five years.
You can decide for yourself whether you want to warm up your engine in the winter before driving. Depending on where you go and where you survive, you may not need to warm up the engine in winter. You can find out what the pros and cons are waiting for you from this action.
pros
One of the main advantages is the very comfort for which we buy a car. It is very inconvenient to be in a cold car, and even more so to drive it. Another plus for warm-up is engine oil, it becomes viscous and the engine starts to work stably. Of course, the most important thing is fuel consumption, due to the fact that the engine is warmed up, our fuel consumption decreases.
Minuses
The main disadvantage is that you will have extra fuel consumption. Harm the oils both in the engine and in the gearbox and chassis. And also the very comfort of being behind the wheel in a cold car.
Common misconceptions
There are also some misconceptions from inexperienced motorists who break their iron horse... To prevent this from happening, it is worth remembering such misconceptions:
- The engine has warmed up to the desired temperature, you can use it at full power. Indeed, in addition to the engine, you need to warm up and undercarriage car.
- Use high rpm to warm up.
- A new car does not need to be warmed up, as the engine will quickly heat up to working temperature than the old one. But it is still recommended to warm up the engine.
We invite you to familiarize yourself with the series trucks HOWO A7. These vehicles are designed to perform broad tasks depending on the vehicle modification. HOWO A7 models https://truck.ironhorse.ru/category/china/sinotruk/howo-a7 began to be produced in 2008, and now they are in great demand among many buyers.
Getting around in your car with comfort is the dream of any driver. In summer, you want it to be cool, and in winter, on the contrary, warm. But in addition to convenience, you must definitely control technical condition vehicle. And in this regard, a person sometimes has to sacrifice his comfort for the sake of prolonging the service and durability of the "iron horse".
Warming up the engine before driving is one such eternal topic of discussion. All motorists were divided into two camps. One - for warming up, others categorically deny it. For many years, the drivers have not come to a consensus. Which of these two camps you are in is entirely up to you.
Do I need to warm up the car engine
Every owner of his own vehicle every year (most often in winter) is asked the same question. Do I need to warm up the engine before driving?
This concept has come to us since the last century. This is due to the fact that the vehicles of that time did not move until the engine reached the desired temperature. Warming up took place at idle. And in order not to stop the engine while driving, it was necessary to wait a few minutes in front of it. And as soon as the minimum required temperature was reached, it was possible to go on a trip without fear of stalling. In order to warm up the engine, it is turned on at idle for one to two minutes. And whether it is right or not, everyone decides for himself.
Today's cars are made more resistant to lower temperatures in the environment.
pros
Decide for yourself whether you need to warm up the vehicle engine, having learned all the pros and cons of this process.
- Comfort. This is an important moment in our climatic zone. Indeed, after a long parking, it will be very cold in the car, and vehicle- almost impossible.
- The engine oil acquires the required viscosity.
- Stable engine performance. After all, jerky driving does not inspire anyone.
- The gaps between the parts are narrowed.
- Reduced fuel consumption.
Minuses
The main disadvantages of warming up the engine before a trip, which car owners talk about:
- Pollution environment exhaust gases.
- Excess fuel consumption.
- Modern engines are prepared for instant start.
- Damage to oil, candles and neutralizer.
Correct engine heating
The process of raising the operating temperature in the internal combustion engine is simple. First, read the instructions. Manufacturers sometimes build in special programs that the driver should not interfere with. In other cases, the engine starts and heats up until the coolant arrow begins to rise. And in cars with fuel injection, the tachometer readings will drop to idle. After that, you can gradually start moving. The time required to warm up each vehicle is individual.
Warming up on the go
Today, many manufacturers advise to warm up the engine while driving. This is primarily due to environmental protection. Environmental guards have become a solid wall against warming up the vehicle at idle. This confrontation is based on the increased pollution of nature during this process... During warm-up, the engine generates exhaust gases with an increased volume of harmful compounds. It should be noted that fuel consumption is also increasing. After all, the engine is wasted.
To warm up the car on the move, a certain list of conditions must be met. They should not shorten the life of the engine, otherwise the manufacturers would not recommend doing so. Since manufacturers are not interested in fast and frequent breakdowns cars. After all, this is fraught with repairs during the warranty period. Numerous returns and breakdowns affect the reputation of the manufacturer, and profit depends on it.
So, idling, the engine gets contaminated due to the rapid ignition of the air-fuel mixture. And during warm-up on the go, the operating time in extreme conditions is significantly reduced.
If you decide that warming up on the go is the most rational for you, then you will have to fulfill several conditions:
- Usage synthetic oil... It should have a high viscosity index. It is this type of oil that is capable of filling all the necessary channels in an unheated engine. And thus you will avoid the appearance of scuffs on work surface... It is especially important to acquire quality oil during the winter. This is due to the fact that it is during the cold season that it is in as soon as possible triggers and becomes a corrosive liquid. And this, of course, will not add years to the service life.
- Smooth ride. It takes a very short period of time to start driving until the minimum required temperature. These are the very few minutes in which you drive out of the garage or parking lot. Therefore, this distance should be driven smoothly, evenly and without jerking. Keep the movement speed low.
- Drive carefully for the first kilometer, after a long stop. Avoid all kinds of potholes and bumps.
Warming up the engine depending on its type and type
During the trial and error of motorists, based on the recommendations of the manufacturers, information was gradually gathered about the need to warm up one or another type of engine.
An urgent question for owners of cars with turbodiesel internal combustion engines: is it necessary to warm up? It is recommended to hold a diesel engine with a turbine at idle speed for a few minutes. And then hit the road. The turbine is to blame. It can be started at a certain speed. crankshaft... It is achieved on high speeds... When the turbine is not running, movement will affect the engine in the form of overheating. This, in turn, will lead to a rise in temperature in the cylinder head and warpage. Therefore the turbo diesel engine it is better to warm up for a couple of minutes while standing in the garage or in the parking lot. So you will protect yourself from expensive repairs.
Information about the need to refuse to warm up the carburetor type of engine on the fly is quite common. Opinion about the possibility of it normal work only at a certain temperature is not entirely true. So, with its excellent performance, the ignition system with the air damper has the ability to build the number of revolutions. Thus, the engine is able to run smoothly after three minutes. But after such an adjustment of the speed, fuel will flow into the engine for some time, washing off the oil from the piston surface. As a result, dry friction is formed between the rings and the cylinder. And as a result - the appearance of seizures. Therefore, it is still better to warm up out of motion with regular monitoring of the air supply.
Another common question among car owners: is it necessary to warm up injection engine? And he is not entirely correct. Indeed, regardless of the type of fuel supply, operation after warming up is carried out according to the same scheme. If you decide to wait for the engine to reach operating temperature, do so with both the injector and the carburetor.
What happens to the engine in cold weather
To understand the question of whether it is necessary to warm up the engine in winter, information about what happens to the car at this time of the year will help.
The parts that make up the heart of the machine are different in material. Each of them reacts to the cold in its own way - the gaps become larger, and the parts, on the contrary, fit closer to each other. Both that, and another leads to early wear and tear. Plus, the viscosity of the oil changes. In the cold, it becomes denser. And before the time when the engine warms up, the engine has " oil starvation". The result - serious damage and overhaul ICE. Therefore, it is important to let the oil warm up evenly and without unnecessary stress in cold weather.
Common misconceptions
Inexperienced motorists sometimes mistake rumor for truth and unknowingly break their vehicle.
To prevent this from happening, explore the most common misconceptions about warming up your car:
- Once the engine reaches operating temperature, you can use it at full power. This is not true, since, in addition to the engine, other parts also need to be warmed up.
- Application high revs for a quick start.
- The new car does not need warming up. Undoubtedly, a recently rolled off the line engine reaches operating temperature faster than a worn one. However, completely warming up should not be neglected.
The seemingly simple question - whether it is worth warming up the car engine in winter - causes numerous controversies every year. This trick, which is relevant for the inhabitants of countries with colder climates, has long been of concern not only for the "green", but also for serious scientists: by warming up the engine, one driver causes irreparable harm to the world around him - this is not to mention the prohibitively expensive fuel that is simply wasted ...
Today we will finally put an end to this dispute and tell you how to properly handle your "swallow" in the winter.
City's legends
In fact, cars older than 1980 need warming up because they run on a carburetor. Without warming up, it did not reach the required temperature and the engine simply stalled.
The injectors solved this problem: there are special sensors that control the mixture of air and gasoline and regulate the desired temperature themselves.
Optimal mode
Actually, the engines of a modern car do not require any heating at all. Just start the engine, wait a minute and drive off smoothly without trying to squeeze the accelerator all the way to the protection.
Effective heating
Think for yourself what can happen to the engine that is forced to work on Idling in a low temperature.

Already at -15, the power unit does not warm up, but is exposed to unnecessary load. The crankcase ventilation system simply freezes over - and this is already fraught with serious damage to the engine. It will be most effective to warm it up while driving.
Valuable fuel
Another significant disadvantage of warming up is fuel consumption. Ten minutes of idle warm-up in the cold is enough for a car to use more than half a liter of gasoline. Have you ever seen prices at gas stations?
Logical conclusion
So we found out that modern car does not need long-term heating. But you shouldn't rush right off the bat: wait one minute - and you can go. The main thing is not to make sudden accelerations. A frozen engine will not tolerate this, taking revenge on the destruction of the grooves where the piston rings
