[Computer-assisted optimal regulation of combustion engines at work sites]

This is a report about the fundamentals of computerised optimation of duration of operation and air exchange for the use of working machines and cars with internal combustion engines in workrooms. The computer programme 'EMI', which bases on the corresponding national standard TGL 33,358/01 to /03, is suitable for the dialog work with the operator. On the foundation of the ensuring compliance with the maximum working place concentration values MAKK and MAKD it is possible to optimize the contrary requirements like air exchange and duration of operation of the internal combustion engines. The programme can be used for GDR-usual computers. It is possible to order the computer programme 'EMI' including user hints at Mansfeld Industrieanlagen Dresden.
