초록 ▼

A method for controlling a compression-ignition internal combustion engine which provides delivery of multiple fuel injection pulses per cylinder firing with precision of pulse quantities, separation, and timing adequate for transition between split and single injection at any speed and load, without disturbing the primary engine governor. The method compensates for variable operating conditions such as supply voltage, injection pressure, injection pulse separation, and injector actuation latency or rise-time.

대표청구항 ▼

[ What is claimed is:] [1.] A method of controlling fuel delivery in a fuel injector having an electronic control valve, the method comprising:establishing a pilot injection rise-time for the control valve;determining a pilot beginning of excitation time based on the pilot injection rise-time;determining an inter-pulse gap between a pilot injection termination and a main injection actuation based on engine conditions;establishing a main injection rise-time for the control valve;determining a main injection beginning of excitation time based on the desired inter-pulse gap and the main injection rise-time to allow split injection over a wide range of engine speeds;determining an observed fuel injection pressure;determining a desired fuel injection pressure based on engine conditions;determining a non-linear pulse adjustment factor based on the measured fuel injection pressure and the desired fuel injection pressure, the pulse adjustment factor being generally inversely proportional to the observed fuel injection pressure;determining a fuel quantity based on engine conditions; anddetermining the pulse width based on the fuel quantity and the pulse adjustment factor.
