The cooling system of the car and functioning

Energy lost to heat

The purpose of a fuel engine to convert chemical energy (stored ‘in, for example petrol or diesel) into kinetic energy. That will always be better, but is still only about 30% of the supplied energy is converted into mechanical power: 70% is lost as heat. Thus, the engine is warm. And if we are not careful, he is even hot. In ancient times it was too bad, because the power was limited. The residual heat of a 10 horsepower motor can easily be dissipated by buitenlucht.Luchtkoeling (or direct cooling) is called so. With increasing engine power problems arose, however refrigeration. If an engine is really hot, then melt all rubbers, the oil is thin as water and turn the piston so far that they get stuck in their cylinders. In short, the whole thing turns into soup. Cooling fins created a larger cooling surface so the wind could discharge more heat and worked with forced air cooling, with fans blowing air through the engine. The modern engine, the more important is the operating temperature. There is really only a temperature at which the engine performs best. All parts shrink because when it is cold and expand as they warm up. They are so constructed so that they are exactly correct size as the engine temperature. To more accurately and be able to cool, the water cooling (or indirect) invented refrigeration. Read the rest of this entry »
