pump.
We
can change the working condition
of
the diesel engine by changing the
position
of
speed adjusting handle. When you
want
to
stop the diesel engine, just
turn the stopping handle.
RFD
type governor is specially used for the diesel engine matched
with
vehicle. You
can use either the full range governor or
the
double poles governor. The double
poles governor
is
useful only
when
the engine idle
without
load or exceeds the rated
speed but not between the idling speed and the rated speed. This
moment,
the
quantity
of
fuel delivered varies trough the changing
of
the position
of
the speed ad-
justing handle.
To make the quantity
of
fuel delivered match
with
the quantity
of
air intaked,
we
'can
install the inlet manifold pressure compensator on the governor
of
the turbocharged
type diesel engine, thus avoid exhausting smoke.

8 The
0285,
0286 type advancer
To improve the working procedure, the engines
of
which the rated speed is above
2600r/min should adopt
0285,
0286 type advancer. When the speed is at
1100
-
2800r/min,
the advancer can make the fuel advanced angle about 0 -
lOQ(;
crank-
shaft turning angle advanced.
The function
of
the advancer is
to
make the fuel advanced angle raise automatically,
thus
meet
the requirement
of
the diesel engine;

The injector is shown
in

The purpose
of
the injector
is
to
spray the atomized fuel into the combustion cham-
