 Function
of systems of cooling
In engine warming up it is necessary to Function of
systems of cooling and a Profitability and reliability
of the engine substantially depend on normal work of
system of cooling. At an engine overheat its capacity
decreases, fuel consumption increases, there is a greasing
burning out that leads to deterioration of rubbing surfaces
of details, occurs teases and smelting of loose leaves
of bearings, destruction of a surface of necks of a
cranked shaft, jamming of the piston and other malfunctions.

Engine overcooling also conducts to malfunctions: losses
of capacity of the engine increase by overcoming of
the increased friction because of more dense greasing;
a working mix, being condensed, washes off a film of
oil from walls of cylinders and increases deterioration
of details of piston group; corrosion deterioration
of a mirror of cylinders as a result of formation of
sulfuric and sulphurous connections increases, etc.
The liquid system of cooling of the engine consists
of a radiator, the pump of cooling means, the thermostat
and the fan. Besides, to it carry a shirt of cooling
of the block and a head of cylinders, the water pump,
gauges of temperature of a cooling liquid, a water distributive
pipe, branch pipes and hoses with fastening details,
drain heater, a heater of a cabin of the driver or salon,
a broad tank.
