METHOD FOR OPERATING A DIESEL ENGINE IN A HOMOGENEOUS CHARGE COMPRESSION IGNITION COMBUSTION MODE UNDER IDLE AND LIGHT-LOAD OPERATING CONDITIONS

摘要

Intake air is restricted to provide an intake manifold pressure that is below the pressure of the ambient atmosphere. Fuel is injected into each combustion chamber at a position of between 15° and 45° BTDC to achieve HCCI combustion under idle and light load operating conditions.
