3. FUEL SYSTEM
[1] GOVERNOR
The governor refers to the load changes to adjust the
fuel quantity supplied to the engine automatically. This
make sure that the engine speed stays constant. This
engine uses an all-speed governor that controls the
centrifugal force of the steel ball (1) weight. The fuel
camshaft (5) turns and makes this centrifugal force,
which balances the tension of the governor spring 1 (7)
and 2 (8).

[2] SMOKE REDUCTION DEVICE (S.R.D.)
This Smoke Reduction Device is to reduce the generation of smoke on start up in normal operating temperature
as well as on sharp acceleration. As this adjustment is performed and sealed before the fuel limitation is set, the
adjustment in the field cannot be performed without a dynamometer.
This Smoke Reduction Device is installed instead of the manual stop lever on the gear case. Especially on
removal of the fuel injection pump, the procedure in the workshop manual should be followed.
