Abstract:
A method for operating an internal combustion engine including an engine of a motor vehicle, the engine having a combustion chamber and operating with an intake phase and a compression phase, the method comprising the steps of:supplying a total fuel mass (K) to said combustion chamber during a single combustion; supplying a first part (KA) of said total fuel mass (K) during said intake phase to said combustion chamber and injecting a second part (KV) of said total fuel mass (K) directly into said combustion chamber during said compression phase; causing said first part (KA) of said fuel mass (K) to comprise a third part (KAE) which is injected directly into said combustion chamber and a fourth part (KAR) in the form of regeneration gas which is supplied to said combustion chamber only during said intake phase; causing said second part (KV) of said total fuel mass (K) provided during said compression phase to be devoid of regeneration gas; reducing said third part (KAE) and increasing said fourth part (KAR); and, supplying so much regeneration gas to the combustion chamber that said third injected part (KAE) reaches a minimum value or zero.
