G. Fuel Injection Timing Control The characteristics of the fuel injection timing vary depending on whether it is the main injection or the pilot injection. Although either the NE sensor or the auxiliary NE sensor is the reference for controlling the injection timing, the NE sen- a. Main Injection Timing sor is ordinarily used for this purpose. ‡ The basic injection timing is calculated in accordance with the final injection quantity, the engine speed, and the water temperature (with map correction). ‡ While starting, it is calculated in accordance with the water temperature and the engine speed. &EWMG-RNIGXMSR8MQMRK *MREP-RNIGXMSR5YERXMX] )RKMRI7TIIH 5) b.
Pilot Injection timing (Pilot Interval) ‡ The pilot injection timing is controlled by adding the pilot interval to the main injection timing. ‡ The pilot interval is calculated in accordance with the final injection quantity, the engine speed, and the water temperature ‡ While starting, it is calculated in accordance with the water temperature and the engine speed.
