Description

The invention (for mechanical engineering, in particular, for engine building, in particular for cooling systems DBT; 1st internal combustion.

The purpose of the invention is reliability.

The drawing presents the scheme of the proposed system.

During operation of DI.1.1I1, the engine is loaded with a load of Venil 11, and the flow in the pipeline 10, soy; 1 and.It is the discharge line; with 2 with a capacity of 9, it closes. Also closed is the anorna1-) 1Y body 15, mounted in the atmofer-tube 14. Lance. The organ 3 opens, opening and circulating the cooling core, the spit g: 1 but the engine contour. v., radiator. Shut-off valve opens

Before () the valve opens the locking or1 en 11, closes behind

a bore opi aH 3 n valve 13 and a secondary thorny organ 15 opens. It moves and the circulating HSCOC 8 pumps the cooling fluid located in radiator 4 through engine 1 into container 9 but through pipeline I). In case of iodine ignition of radiator 4 and the clock and suction line 5, between the radiator 4 and the return valve, the sensor 6 is activated for the presence of cooling (coolant) liquid and sends a signal to stop the engine. After stopping the engine; 1I, the check valve 7 prevents the leakage of fluid from the tank 8 and the engine; 1 1 into the radiator.

Before starting the engine, the shut-off valve 3 and the valve 13 open and are in place, the radiator 4 is filled with a coolant from the tank 9. After the filling, the additional valve body 15 and E eiti; 1 11 are closed The engine is ready to skid.

Los.le off engine, water is drained only from radiator sections. Since the water contained in the radiator pipes, as a rule, does not exceed 10% of the total volume of the cooling system, this makes it possible to use as an additional capacity. The cooling time of the cooling system is determined by the cooling time of the 15 radiator pipes, therefore draining the water from the radiator increases the safe time of the simple system c.1x: 1 of the motor delays after it stops. At the same time, the working time of the bodies is reduced with the aim of the burner, which allows a newer i l ia lzhiluatai iodnoy fuel economy iost}) | n; of dizideas
