METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE AND INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a method for operating an internal combustion engine (10) comprising at least one combustion chamber (14), wherein fuel is directly injected into the combustion chamber (14) during a work cycle of the internal combustion engine (10). According to the inventive method, fuel is directly post-injected into the combustion chamber after the fuel is injected for the actual work cycle. Said after-injected fuel is ignited as a result of the ignition of the injected fuel already occurring in the combustion chamber. The invention is characterized in that exhaust gases discharged from the combustion chamber (14) are heated for post-combustion of the non-combusted fuel content before they are fed to at least one catalytic converter (18, 20, 22) for aftertreatment of the exhaust gases.
