Process for the regulation of the optimum operational behavior of an internal combustion engine

摘要

A process for controlling the operation of an internal combustion engine based on the volumetric efficiency of the engine to define a primary nominal fuel quantity. The process also includes measuring the fluctuations in the volumetric efficiency. In order to operate the engine in a preferred leaned-out condition, a nominal set- point value of the permitted range of fluctuations of the volumetric efficiency is established and the actual measured fluctuations are maintained in that range by changing the fuel metered out to the engine. PP Various methods for measuring the volumetric efficiency indirectly by pressure measurements in the induction tube are presented.
