ABSTRACT:
A system and a process for operating a diesel engine using an automatic engine control which, as a function of characteristic diagrams, automatically controls the operation of the diesel engine and permits an automatic rich/lean controlling of the diesel engine. The automatic engine control includes a computer which, as a function of predetermined change-over criteria, causes a change-over to the rich or the lean operation of the diesel engine. A sensor system communicates with the computer and monitors the parameters necessary for change-over criteria. A memory communicates with the computer, the memory storing separate characteristic diagrams for the operation of the diesel engine for the lean operation and for the rich operation.
