Прочитайте текст. Выполните задания.

Cooling system

Then an internal-combustion engine operates, the parts coming in contact with hot gases are strongly heated. If the temperature of the pistons, cylinder heads, valves and cylinders becomes too high, undesirable effects appear such as deterioration of cylinder filling, power reduction ignition of fuel. Very often the oil burns out and loses its lubricating properties.

If the engine is excessively cooled, the portion of heat that goes for useful workdiminishes and the power of the engine drops.

The cooling system consists of the aggregate of all the devices ensuring the required thermal duty of the engine.

A water cooling system operates in the following manner: the water present between the cylinder walls and the cylinder heads cools the heated inner walls and become heated itself in the process. It often flows to the radiator, where it is cooled down by air. The cooled water is again redirected to the engine water jacket.

Forced cooling, when the water is circulated by a pump, is most common in modern engines. Cooling systems may be open or closed. In the first case, the volume of the system is not closed tightly. In the second case the plug of the cooler is provided with a two-way steam-air valve, which is opened by an excess pressure of steam in the system and also when the pressure in the cooler drops below atmospheric by 0.05-0.02 kg/cm2.

To enable the engine to operate normally, the temperature of the cooling water should be maintained at 80-90 irrespective of the load and the temperature of the environment. For this purpose and also to speed up the warming of the engine in starting, provision is made for adjusting the cooling rate which can be varied by changing the volume of the air stream passing through the cooler and also by changing the rate of water circulation.

In addition to water cooling, modern international-combustion engines, especially low-power types, often air-cool the ribbed cylinder surfaces with the aid of fans.
