(4) Fuel injection rate adjustment resistor correction amount
•
To limit inconsistency in the injection quantity, the injection quan-
tity is corrected by the fuel injection rate adjustment resistor.
2.4 Fuel injection timing control
(1) Main injection timing
•
The main injection timing is calculated from the fuel injection
quantity and engine speed.
(2) Pilot injection timing (pilot interval)
•
The pilot injection timing is calculated from the fuel injection
quantity and engine speed.
2.5 Fuel injection pressure control
• The fuel injection pressure is calculated from the fuel injection
quantity and engine speed.
2.6 Warm-up acceleration function
• The warm-up acceleration function accelerates engine warm-up by varying the engine’s idling speed in accor-
dance with the engine’s coolant temperature. It can operate either automatically or manually. Selection is made
using the idling speed adjustment potentiometer.
