to them, as well as the types, design and operation of thermostats
(liquid and solid filler), advantages and disadvantages.
Look at the various designs of body heaters and cabs, engine
heater.
Lubrication of engines depending on the method of oil supply
to the surfaces of friction can occur by spraying, under pressure
and self-propelled. In modern engines, a combination of all types
is used, so the engine lubrication system is classified as a
combination of lubrication systems.
The oil circulation in the lubrication systems is via a pump.
It is necessary to follow the path of oil from the oil receiver to
its return to the crank, noting which parts are lubricated under
pressure, and which are sprayed and self-propelled.
The operation of the lubrication system is controlled by
special valves. It is necessary to clearly indicate the role of valves:
reduction, overflow, turning on the radiator, drain.
Radiators and filters can be included in the system
sequentially and in parallel. It is necessary to understand the
methods of oil purification, the advantages and disadvantages of
each of them.
The lubrication system includes control devices, which control
the oil level in the crankcase, the oil pressure in the main line and
the temperature. It is necessary to know the design and principle of
each device and device, to follow the movement of air and
crankcase gases for the case of open and closed ventilation of the
crankcase. Understand the main differences between systems for
lubrication of engines with dry carter.

3 Directions for preparation for the lesson

to study:
- appointment, general schemes, structure and principle of
cooling and lubrication systems;
- designs of cooling systems, heating, lubrication of the engine
and heating of various types of cars.
Consider:
- design features of systems of cooling and heating of the car
