Abstract
A fuel injection control method for a fuel injection pump having a high pressure chamber in which fuel is pressurized, a low pressure chamber, a communicating passageway connected to the high pressure chamber and the low pressure chamber, and a solenoid valve for selectively opening and closing the communicating passageway. While fuel is pressurized, the solenoid valve is selectively closed and opened, so that the pilot injection and subsequently main injection are carried out. A starting time and a terminating time of pilot injection are determined depending on operating conditions of said engine, and main injection of fuel is started when a predetermined period of time elapses from the terminating time of the pilot injection.
