OPERATING METHOD FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide technique which can control a start of combustion and a maximum rate of combustion independently of each other for improving combustion process control of an internal combustion engine burning a self ignited homogeneous fuel/air mixture. SOLUTION: This internal combustion engine is provided with a device controlling an inactive gas component in a combustion chamber 7 while having at least one operating mode realizing combustion by self ignition of a self ignited homogeneous fuel/air mixture. The inactive gas component control device comprises an external exhaust gas re-circulating device 10 and a residual gas control device 26, and supply air temperature transition and the inactive gas component are adjusted by control of a residual gas component and control of an external re-circulated exhaust component.
