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 to
the fuel tank through fuel
overflow pipe (g).
