Method for determining gas volumetric efficiency of internal combustion engine e.g. directly loaded diesel engine for motor car, involves adjusting base volumetric efficiency according to determined offset-value

摘要

The method involves detecting an actual operating value of a volumetric efficiency parameter of an internal combustion engine (1) in a current operating point. A base value of the parameter for current operating point is determined based on a parameter map. An offset-value is determined based on the difference between the detected actual operating value and the determined base value. The base volumetric efficiency is adjusted according to the determined offset-value. An independent claim is included for a device for determining volumetric efficiency of internal combustion engine.
