Abstract

A diesel internal combustion engine in which during the starting and partial load operation, a number of the cylinders are operated as compressor cylinders and a number as engine cylinders. The supplied charging air of one compressor cylinder (26) is used as actuating medium for the valves (35 to 42) which are to be controlled corresponding to the operating condition of the internal combustion engine, in the connecting lines (27 to 34) between the compressor cylinders (19 to 26) and the engine cylinders (11 to 18) in the absence of a compressed air network. As a result thereof, auxiliary energy of the internal combustion engine (10) is needed only for the initiating control and a rapid shifting of the operating conditions is attained with minimum expenditures.
