Why is driving on a cold engine dangerous?

The debate about whether it is necessary to warm up the engine has not subsided for many decades. In the past, it was really believed that carburetor engines must be warmed up, which eliminates engine wear, significantly extending its service life. Today, with the advent of modern engines that are fully controlled by automatic equipment, many of us are sure that warming up with such motors is not required. Let’s talk in more detail about whether it is necessary to warm up the engines of modern cars today. Remember that ignoring the basic rules of car operation leads to its damage up to the fact that you will have to use scrap car removal scarborough.

Optimal engine parameters
It is believed that as soon as all working fluids and parts in the engine reach the optimum temperature, such a motor is considered warmed up, it works correctly, there are no problems with injection, and premature wear of various parts is prevented. To warm up the engine to such a temperature, literally 5 minutes of car movement is enough.

If in summer the temperatures are high enough, oil and other technical fluids are initially warmed up even after a long parking of the car, therefore, there will be no problems with premature wear in such a case. But in winter, the oil in the engine can thicken, the temperature of the metal elements drops significantly, after a long stay when starting the engine, severe wear of the engine may appear, which significantly shortens its life.

It is believed that on such a cold engine, the piston and piston rings take the maximum load. These elements are sensitive to low temperatures and can wear out quickly on a cold engine, after which a motor overhaul is required.

Positive aspects of warming up the motor
A cold engine will consume much more fuel, which will significantly increase the costs of the car owner. Therefore, by warming up the engine at idle in the parking lot, you can significantly reduce your costs for the purchase of gasoline or diesel.

It was also noticed that with regular warming up of the engine, the wear of its elements is significantly reduced, there are no critical engine breakdowns, and the service life of the car is extended.

When the engine warms up, the temperature of the oil increases, which acquires its fluidity, well lubricating all the moving elements of the engine. The same applies to the power steering, the hydraulic fluid in which starts to work correctly, making it easier to turn the steering wheel.

On a cold engine, the car cannot adequately respond to pressing the brake and gas pedal; in some cases, this is simply dangerous and can lead to serious road accidents.

Do I need to warm up the motor
There is simply no universal answer to this question. Modern engines are controlled by automation, which monitors all the parameters of the engine, if necessary, changing the degree of enrichment of the mixture and raising the speed on a cold engine. All this allows the engine to warm up even while driving, eliminating any serious load on the engine. Most experienced drivers say that it is much more important to stick to a quiet ride after starting the engine, in no case to raise the speed and not to spin the engine to the maximum. It is not at all necessary to warm up the engine under the house or in the parking lot for 5 minutes, but the first 10 kilometers of the trip, it is necessary to spin the engine up to only two, maximum three thousand crankshaft revolutions per minute.

Let’s sum up
Warming up the engine allows you to slightly reduce fuel consumption and protects the moving parts of the engine from premature wear. However, remember that today it is much more important, after a long stay, to start moving at a dimensional pace and not to raise the engine speed too much, which will allow it to warm up correctly, and this excludes any serious malfunctions of the power unit.
