Abstract

In a turbocharged diesel internal combustion engine (10) with low compression ratio, at least one cylinder (11) operating as an engine cylinder is charged during starting and at partial load operation by several cylinders (18, 21, 28) operating as compressors. The pistons of the compressor cylinders (18, 21, 28) lead the piston of the engine cylinder (11). As a result thereof, the engine cylinder can be charged during its compression stroke. The compressor cylinder (28) which by reason of its large angular ignition spacing to the engine cylinder cannot feed directly into the engine cylinder, delivers its supplied air at first to another compressor cylinder (18) which is located more favorably. Only thereafter, the air of the two compressor cylinders (18 and 28) is fed in common and in parallel with a further, possibly also favorably located compressor cylinder (21), to the engine cylinder (11).
