Should I warm up the vehicle in the winter
• Whether it is necessary to warm up the car in the winter
Sooner or later, any driver who uses the Internet, get on Autoforum where fiercely debated the feasibility of the engine warm during cold weather. In such topics faced foreheads dozens, if not hundreds, of experienced (and not) of motorists. They bring a lot of arguments, and each defends his own, of course, the only correct point of view. So whether or not to heat in winter or it is better to go by car - it is a question to which the answer was given the best possible experts - engineers.
When discussing the "warm or not warm" car in the winter, often sounds somewhat contradictory arguments. Many drivers say that a cold engine will work fine, as long as fuel and oil is pumped through the system, and it is a problem when a large "red" on the street. To increased motor temperature and warm it up, you need to spend 5-10 minutes, during which time the machine is idle, ie. E. The fuel is spent, but go no one does not go anywhere.
Their opponents believe that you should not move on unheated car, t. To. The oil in the aggregates and the transmission has not yet acquired the operating temperature, and so the details will wear out faster. Who is right in this dispute, has tried to understand the profile engineer.
If you believe "the word" auto dealers, the modern machines even in the dead of winter, you can not warm up. It is enough to turn the key in the ignition, wait a few seconds until the motor is not fully "wake up" and just go. That is the official position of the marketers whose job it to sell the car at all costs - "why warm the engine when the car rides and so?". In this case, no time is wasted, and also saves fuel.
But the "technicians" working on the same dealer, on the contrary, it is advised to warm up the car in the winter. "Wasted" gasoline or diesel fuel, is easy to overlap the cost of engine overhaul, which was postponed to a distant time.
Experts say that each cold start of the motor causes the damage of friction parts, such as cylinder - piston, crankshaft journals - bearings. If the temperature in the "minus" oil thickens and worse lubricates the friction pair.
Modern oil, as some motorists become many times better than the ones that were 20-30 years ago, and therefore it is possible to do without heating. But engineers say that this is still not the case. Firstly, any oil during cold weather becomes more viscous and less fulfills its primary function, and secondly, not all drivers use an expensive "synthetics".
While the engine speed when starting small oil slowly but effectively warms hot piston and combustion chamber walls. If, however, give the right speed, it may come the so-called "oil starvation" - a situation where lubrication between the seal faces is not enough. E. The higher the engine speed during heating, the more intense wear. A good example would be the following failure: if "pogazovat" a cold engine may crank inserts.
Experts call following a cold start mode is optimal: a couple of minutes to idle, warming up the engine, and then drive a few kilometers without a large load, trying not to spin the motor. Just so you can save the life of the power unit, not to spend a lot of time to warm up, as well as to save fuel.
