Control strategy and model for diesel combustion mode switching

摘要

A diesel engine combustion mode changeover control system (12) comprising: a changeover switch determination module (50) that initiates a changeover request (60) to determine, based on engine speed (58) and fuel quantity (57) and / or torque between a Mode with premixed compression ignition (PCI mode) (102) and / or a diesel combustion mode (100) toggle; a transition module (52) that directs the PCI mode (102) and / or the diesel combustion mode (100) based on the switching request (60); and a control module (56) that controls the desired airflow (86), the desired amount of fuel (88), and / or the desired time of fuel injection (90) based on the instruction; characterized in that the transition module (52), upon receiving the switch request (60), directs a transient mode from diesel combustion (100) to PCI (102) or a transient mode (104) from PCI (102) to diesel combustion (100), prior to Directing to PCI Mode (102) or Diesel Combustion Mode (100).
