Set Injection Quantities
• Basic Injection Quantity
This quantity is determined by the engine speed and the accelerator opening. With the engine speed constant, if the
accelerator opening increases, the injection quantity increases; with the accelerator opening constant, if the engine
speed rises, the injection quantity decreases.
• Starting Injection Quantity
This is determined based on the basic injection quantity for when the engine starts up and the added corrections for
the starter S/W ON time, the engine speed, and the coolant temperature. If the coolant temperature is low, the injec-
tion quantity is increased. When the engine has completely started up, this mode is cancelled.
• Injection Quantity for Maximum Speed Setting
Determined by the engine speed. The injection quantity is restricted to prevent an excessive rise in engine speed
(overrun).
