Elements of giving
of fuel, clearing of air and release of the fulfilled
gases
 The
fuel tank has a jellied mouth with the mesh filter,
and also internal partitions for elimination of sharp
movings of fuel at car movement. In a stopper of a
jellied mouth there is a steam-air cooling valve.
In a tank it is located the gauge of level of fuel.
Capacity of fuel tanks is usually calculated on 500
km of run. Make fuel tanks of a steel sheet.
The fuel pump serves for giving on gasoline from a
tank to the carburettor. Fuel pumps in disorder of
the engine or sideways covers of distributive gear
wheels have. The greatest distribution was received
by fuel pumps type. The fuel pump is put in action
directly from the clown of a camshaft or through a
bar, and also there is a lever for manual giving of
fuel. At the clown or pressure of a bar upon the external
end the lever of the pump the diaphragm is delayed
by a rod downwards, and the delivery spring is compressed.
Over a diaphragm it is created under which action
inlet valves of the pump open. Fuel fills a cavity
under a diaphragm. When the clown will run from an
external shoulder of the lever or pressure of a bar
weakens, the diaphragm under the influence of a delivery
spring comes back in a starting position. Under a
diaphragm pressure of fuel under which action inlet
valves are closed is created and the final valve opens.
Fuel from the carburettor is forced out in the carburettor.
To submit fuel to the carburettor at the idle engine,
it is necessary to press the lever of manual pumping
of fuel some times.
On diesel engines establish the pump of piston type
which fix. The drive is carried out from shaft of
this pump.
When the piston moves downwards under the influence
of a spring, over it depression is created and occurs
fuel in this cavity. And the fuel which is under the
piston, is forced out in a highway. At piston movement
upwards under the influence of the clown fuel is pushed
out through the delivery valve in the same highway
and through the filter of thin clearing gets to the
fuel pump of a high pressure. The piston at achievement
will not move to highways of the established pressure,
as pressure of a spring over the piston and fuel under
the piston will be identical.
The manual pump is established on the case the pump.
If the engine does not work, by means of the manual
pump it is possible to pump up fuel in a highway.
Besides, it is used for removal of air from a power
supply system before engine start-up. High pressure
make of steel tubes. The ends of tubes have a cone
and are pressed by nuts to nests of unions of the
fuel pump of a high pressure and engine atomizers.
Sedan – two- or four-door, four-five-seater, with
separate volumes for the engine, passengers and luggage;
The versatile person – the car with the carload form
of a body, is used for transportation of people and
cargoes;
Cabriolet – the four-six-seater car with a collapsible
roof and demountable walls of lateral windows.
