SU369286A1 - COOLING SYSTEM OF INTERNAL COMBUSTION ENGINE - Google Patents

Description

one

The invention relates to the field of engine-building and can be used in cooling systems for engines of light-tonnage vessels.

Cooling systems for internal combustion engines are known, which contain a mixing tank with a connection pipe for supplying heated water from an engine installed in a supply line for supplying flowing water to an engine. In such cooling systems, water heating is difficult due to the lack of a closed water circuit through the engine.

In order to increase the efficiency in the proposed cooling system, the output of the line into the mixing tank is designed as a nozzle placed in the nozzle, the line is provided with a choke, communicated with a thermostat placed in the nozzle.

FIG. Figure 1 shows schematically the proposed cooling system; in fig. 2 shows the exit from the line into the mixing tank; in fig. 3 - throttle connected to the thermostat; in fig. 4 - mixing tank, made integral with the water jacket of the engine.

The mixing tank / is installed in the main line for supplying flowing water to the engine, formed by tube 2 for supplying flowing water to the container and tube 5 for supplying water from the container to the water jacket 4 of the engine. The tank is equipped with a pipe 5 for supplying heated water from the engine and a drain pipe 6 for draining excess water overboard. The output of the line into the mixing tank is designed as a nozzle 7 placed in the nozzle. The inlet line to the mixing tank is equipped with a throttle 8, communicated with a thermostat 9 placed in the nozzle, for example, using a pull 10. The neck 11 serves to fill the tank and the system whole

If the container is made in a water jacket (Fig. 4), then the nozzle is placed in the partition 12 separating the container from the jacket.

The pipelines entering the system form a closed circuit for the circulation of water through the engine jacket and the tank and supply and drain line formed by tube 2 and tube 6.

A gtri closed throttle 8 circulating in a closed loop creates a thermosiphon effect and the engine warms up quickly. With the throttle open, nozzle 7 creates an ejection effect and contributes to an increase in the intensity of water circulation through the engine jacket.

The thermostat 9 regulates the amount of opening of the throttles depending on the water temperature at the outlet of the engine and, as a result, this temperature condition of the engine is maintained automatically.

Thus, the described system provides a quick warm-up of the engine at start-up and automatic maintenance of the set temperature in operation under load.
