METHOD AND DEVICE FOR OPERATING AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a method and a device for controlling an internal combustion engine with the most accurate possible modelling of scavenging operations. The aim of the invention is to provide a method and a device of this type that can be used without any problems with the engine controllers that are currently available. To achieve this, an exhaust back pressure (PE_DYN) is determined during the valve overlap from a temporally determined exhaust back pressure (PE) as PE_DYN = IP_PE_COR_FAC(N). PE or PE_DYN = AM + IP_PE_COR_FAC(N). (PE - AMP).
