Disputes about the warming of the engine are already long enough. Someone claims the need to warm up the power unit, and someone declares the uselessness of this venture. Some sit and immediately go, and others warm the motor to the operating temperature and only after that begin traffic.

Features of the car operation in winter

The car's engine in winter cools very quickly, and with a long parking lot, for example, overnight in the open area, its temperature becomes an identical ambient temperature. At the same time, the difference between starting values \u200b\u200band optimal for operation most often exceeds a hundred degrees.

The most important problem of cold start is the motor oil. Its viscosity significantly depends on the ambient temperature. In the cold, oil consistency becomes more thick, which worsens the lubrication of the driving elements of the engine. It entails their elevated wear.

Heavy engine launch to cold

In addition to the foregoing, the following factors affect the operation of the power unit at low temperatures:

• Type of fuel - A car equipped with a dieselm, necessarily requires winter diesel fuel.
• Fuel supply type - Old cars with carburetor injection are often distinguished by manual throttle control.
• ACAP or MCPP - Anyway there is an oil in the gearbox, which also changes its viscosity under conditions of low temperatures.
• Computer control over warming motor - The onboard controller selects the most optimal supply of the mixture, while the power unit goes to the operating mode of temperature in the shortest possible time.

During the approach to the working temperature range, the viscosity of the liquids becomes normal and problems with lubrication and increased mechanical wear of the elements of the motor and gearboxes are moved to the background. Another goal of warming up the engine in winter is to bring the cabin to a comfortable condition, as well as defrosting the glasses.

Do I need to warm the engine in winter

It should be started with the fact that the technical manual for the use for most modern cars says that there is no need to warm the motor before traveling. Manufacturers indicate that motor oil and other technical fluids are evenly heated when driving at low revs. That is, the manufacturing technologies of the engine and high-quality techniques make it possible to start riding in a gentle mode, without applying special damage to the engine motor.

The main goal of such statements is the desire of manufacturers to convince car owners in the fact that you do not need to warm the engine. This is done, first of all, not to increase the service life of the motor, but in favor of ecology. Well known is the fact that any engine in motion warms up faster, and a catalyst begins to function with increasing temperature. Obviously, warming up the engine at idle turns takes longer, and the fuel consumption during the warming of the motor in the winter increases. According to these reasons, it is proposed to warm the engine on the go to reduce the toxicity of the exhaust gases as quickly as possible.

It is worth noting that in many European countries the legislation consolidated certain norms that prohibit warming up or long operation of the motor on the XX in the residential area. That is, it is forbidden to warm up the motor in the winter or allow the engine to work in the summer in idle mode, otherwise the driver can impose a fine. Considering the fact that the car in the CIS for most people remains the subject of substantial material value, and environmental standards are not so stringent, high attention, first of all, is given to the operation of the engine. It is also worth noting that the soft European climate cannot be compared with the complex operational conditions of the engines in severe frosts, relevant to our winters.

But supporters of failure to warm up say that the car manufacturer would never indicate in the manual, which can be riding immediately, warming the engine on the go. The main argument is anxiety about brand reputation and warranty obligations to the buyer. With this opinion, you can agree, but only partially. The generally accepted practice today is a guarantee for a new car, which, on average, is 100-150 thousand mileage kilometers. Such an indicator is actually actually any modern motor without serious breakdowns. That is, the margin of durability involves such use without warming, given the observance of a number of additional conditions. However, not every car owner in the CIS changes its car to a new one at the end of the warranty and is not ready to make overhaul through 100-150 thousand kilometers. Considering all the above, it becomes clear that neither modern oils nor technology can significantly affect the features of the work of the engine and the laws of physics. If you want a maximum to extend the service life of the engine, then the engine must be warmed.

is it necessary to warm the carburetor engine

The modern automotive industry abandoned the equipment of the engines with similar fuel supply systems. But, on our roads, it is often possible to meet old "Muscovites" and "Zhiguli", which continue to ride in the endless expanses of our country. To start the cold motor, the motorist has to play the role of an on-board computer, that is, to independently adjust the fuel supply to the cylinders using a suction knob. Thanks to it, the desired degree of enrichment of the mixture is achieved, which is due to the control of the throttle position of the carburetor. In this case, the heating of the car in the winter is characterized by a certain ritual:

• First, the battery is warm - for this it is necessary to briefly turn on the Middle Light (about 30 seconds).
• Disconnect all excess consumers of electrical energy - headlights, fans, and so on.
• Slit clutch.
• Remove the sublicas to the required level - it is not always necessary to overlap air to the maximum, it depends on the engine and ambient temperature.
• Submit the command to the starter using the ignition key - if the engine did not immediately start, you need to repeat the attempt after about 30 seconds, since the battery capacity will be restored during this time.
• When the motor starts, adjust the turns of the XX - they should be about 1200 rpm. This is done using a suction knob.
• Release the clutch pedal - in the frost then the engine can stumble, because the viscosity of the oil in the gearbox can be very large.
• After some time, turn on the fan of the stove and warm the interior - the hot stream is not recommended to direct immediately on the glass, since it is possible to get a crack from the temperature drop.
• During the warm-up of the motor, gradually remove the subference - in the operating temperature ranges does not require the enrichment of the mixture.
• After warming up, completely remove the sublicas.

Some auto imports with carburetor motors are equipped with automatic sucks. The throttle control in this case occurs without the participation of the motorist.

do I need to warm the diesel engine

Morning problems with a diesel engine are due to the fact that fuel has fallen into the benzobac, which does not correspond to the winter operating conditions. In winter dielair, there are special additives that prevent condenses in low temperatures. Do you need to warm the diesel engine in winter - the question is rhetorical. Diesel engines are characterized by the same problems as gasoline. Plus, in frost, fuel filters are clogged with harvested paraffins, and this reduces their permeability. If the fuel is lacking, the motor is very difficult.

There are several ways to combat these phenomena:

• Candles of heating - Heat fuel to operating temperatures.
• Winter additives are the easiest way to add 5-15 percent of low-fledged gasoline to fuel.
• Return warm fuel in a benzobac through the return - This is done by preheating fuel.
• Electric heating filter- melts paraffin sediments.

do I need to warm the injection engine

The fuel supply to the cylinders by means of nozzles is controlled by the injection computer. The onboard controller analyzes information about the air temperature, which enters the motor, the temperature of the engine itself, the crankshaft turnover and the temperature of the coolant. Based on this information, the electronics gives the servo command to change the position of the throttle. It was much easier to warm the car in the winter - no need to perform some rituals, just start the motor. All other operations will perform a programmed machine.

If you left and did not wait for the operating temperature range by the engine, follow these rules:

• The first few kilometers do not gas - the lubricant is not yet free and the motor functions in oil starvation mode.
• The checkpoint is also still frozen - it does not need to be operated as "Formula 1" riders.
• No need to sharply load the suspension - the oil in the pillows under the engine and shock absorbers is still very viscous, these nodes must gradually come to the working state.

Modern cars are equipped with various devices that facilitate the operation of the car in the cold period.

No need to think, as in a short time warmly warm the car in the winter, for the comfort of passengers and the driver there are such options:

• Heated steering wheel.
• Heated seats.
• Heated front and rear windows.
• Heated mirrors.
• The climatic installation that heats the salon before, rather than the classic stove works.

Of course, all the data "beams" help the motorist to leave the parking lot in the morning after the frosty night. But do not forget that 10 minutes of the cooling engine function can be equated to 100 km. Run. The piston group is wears, first of all, due to the fact that the piston made from the aluminum alloy heats up much faster than the steel cylinder sleeve. The gaps are significantly reduced, and the oil does not provide the required lubricant due to high viscosity. Suffer liners, rings, PPC bearings. Of course, modern additives are able to smooth the strong dependence of the viscosity of the oils from temperatures, but no one has canceled physics.

Useful advice

Of all the above, we can conclude that it is necessary to warm the vehicle in the winter to prolong the service life of the motor and gearbox. The warm-up time depends on the type of power unit and gearbox. If the frost is small, enough for 3-5 minutes to warm the oil. But to free the glass from the land, it will take a little longer.
