1-M6
In Normal Operating Temperature
On start up of the engine, the rack of the fuel injection
pump is pushed into the position by the start spring
where the amount of injection comes to maximum.
The start up of the engine in this condition makes the
fuel injected more than it requires on starting up in
normal operating temperature, and smoke is generated.
The thermostat of the Smoke Reduction Device is
activated on starting up of the engine in normal operating
temperature, and then excessive injection of fuel is
controlled.
On sharp acceleration in normal operating
temperature, the lever acts as a damper, and the rack of
the fuel injection pump moderately moves to the
direction where the amount of injected fuel increases,
and the amount of smoke during acceleration is reduced.

In Low Temperature
Low temperature starting is secured because Smoke
Reduction Device is disabled on starting up the engine in
low temperature, and the rack of the fuel injection pump
is pushed into the position of the maximum amount of
injected fuel by the start spring.
