Processes to control fuel distribution in a fuel injector, to determine fuel injection control valve rise time in an electronic fuel injector, and to determine a pulse width for an electronic fuel injector

摘要

'' PROCESSES FOR CONTROLLING FUEL DISTRIBUTION IN A FUEL INJECTOR, TO DETERMINE FUEL INJECTION CONTROL VALVE TIME IN AN ELECTRONIC FUEL INJECTOR, AND TO DETERMINE A COMBINATION process for controlling an internal combustion engine with compression ignition (12), which provides distribution of multiple pulses of fuel injection per cylinder, firing with precise pulse quantities, separation and timing suitable for transition between split injection and single injection at any speed and load, without disturbing the primary motor controller (22). The process compensates for varying operating conditions, such as supply voltage, injection pressure, injection pulse separation and injector actuation latency or ascending time.
