METHOD FOR LOAD TRANSIENT CONTROL BETWEEN LEAN AND STOICHIOMETRIC COMBUSTION MODES OF DIRECT-INJECTION ENGINES WITH CONTROLLED AUTO-IGNITION COMBUSTION
摘要
<p>A method is provided for control of a direct-injection engine operated with controlled auto-ignition (HCCI) during load transient operations between modes of lean combustion low load (HCCI/Lean) and stiochiometric combustion medium load (HCCI/Stoich.). The method includes 1) operating the engine at steady state, within a homogeneous charge compression-ignition (HCCI) load range, with fuel-air-exhaust gas mixtures at predetermined conditions, for each speed and load, and controlling the engine during changes of operating mode between one to another of the HCCI/Stoich. medium load mode and the HCCI/Lean lower load mode by synchronizing change rates of predetermined controlled inputs to the current engine fueling change rate.</p>
