ABSTRACT:
In a diesel internal combustion engine (10) having a low compression ratio, at least one cylinder (11) operating as engine cylinder is supercharged during starting and in the partial load operation by several cylinders (12, 13) operating as compressor. The piston of the first compressor (12) which is used for the direct charging of the engine cylinder (11), leads the piston of the engine cylinder (11) exactly so far that the air compressed by the same is fed directly into the engine cylinder (11) during the beginning of the compression stroke. At least one further compressor cylinder (13) supplies its air to an air storage device (22) which is connected with the engine cylinder (11) by way of a line (24) adapted to be closed off by a valve (23). The valve is controlled in the opening direction by the compressed air of the first compressor cylinder (12) so that the air of the storage device (22) together with the air of the first compressor cylinder (12) reaches the engine cylinder (11) at the correct instant and is further compressed thereat by the piston of the engine cylinder (11) up to the fuel injection.
