It is worth saying that there is such a thing as the “working temperature” of the engine.
It means the optimum temperature at which the power unit is functioning normally in nominal mode.
So diesel engines, this temperature is from 85 to 90 degrees Celsius, and petrol — this parameter is from 90 to 100 degrees, in some cases up to 110.
Since most fluids works effectively only when the operating temperature of the engine, when driving on a cold motor there are short-term failures in traction or there is a decrease in dynamics, as in this case decreases the efficiency.
For example, the oil in the cold the power unit will not be able to optimally perform its functions, that is, lubricate all moving mechanisms without a normal temperature, and this leads to wear and tear.
Therefore, the expert said that it is recommended to warm up the power unit of the vehicle at least as long as the speed does not decrease with increased so-called warm-up, to idle.
And only after that you can slowly start moving, while trying not to raise at this stage the revs above 2000 for petrol engines and more than 1,500 for diesel engines.
Also in the bitter cold — 20 degrees below — it is recommended to warm the engine a little longer, as long as the coolant temperature rises to a minimum of 50-60 degrees.
It is worth saying that this Board is more suited to vehicles with gasoline engines because the diesel powertrain is impossible to warm up at idle. For this “diesels” need the stand-alone preheaters.
While the most efficient diesel engines are warmed up during the drive.
