Drivers know: after long Parking of the car in the cold to start the engine. At low temperatures freeze even antifreeze! And those who use it for cooling water and drains it at night, lose the opportunity to fill the radiator with hot water — burst frozen in the cold of the cylinder head and the block, and the boiling water almost immediately freezes, forming ice plugs.
Sometimes because of this the driver has the clock not to turn off the engine, which leads to wasteful consumption of fuel, reduction of engine life. However, in the morning, the driver still has to warm up the transmission, spreading and sometimes under machine a fire.
The situation is much easier when using the heaters, which with a small flow of fuel supports the engine temperature at a level necessary for its launch.
This flameless combustion heaters.
Their principle of operation is that a pair of liquid fuel — gasoline or alcohol — are oxidized with air oxygen in the presence of a catalyst directly on the surface of the heating element; the heat is generated not by combustion, but by a chemical reaction.
The scheme of this “stove” is shown in Fig. It consists of a fuel reservoir with the neck and stopper; a burner in which is embedded a heating element, a frame and two metal mesh with a lining of asbestos wool impregnated with the catalyst; asbestos or cloth wick, which is fed from fuel tank to the burner (cotton wick and lower brackets of the heating element for protection from the erosion of the parts a layer of asbestos wool, not impregnated catalyst).
