4-1 FUEL FILTER (OPTIONAL PART)

For protecting injection pump and injection nozzles from
impurities, the fuel is sent through the filter before reaching
the fuel pump.
Fuel enters the filter, passes through the filter element (d)
circumference toward the center for filtering. The filteration
granular size is from 10 to
19
In operation, fuel from the fuel
tank (a) enters the filter (b),
where it is cleaned and absorb-
ed by the suction of fuel pump
(c). ( V1502-B, V1702-B,
V1902-B are available) The
pump then pushes it to the
injection pump (d), where it is
pressurized under high pressure
and through the injection pipe
(e), it is delivered to each injec-
tion nozzle (f), which atom-
iies and injects it into the com-
bustion chamber at the proper
time and amount. Excessive
fuel from nozzles returns
the fuel tank through
overflow pipe (g).
(0.01 to 0.02mm).
