Intake system for an internal-combustion engine for use in one-stage or

A piston for a reciprocating piston internal combustion engine, in which the piston top (11) is secured to the wrist pin (14) by way of two support bearings (18) independent of the piston skirt (12). The piston ring carrier (16) connected with the piston top (11) is additionally connected with the two support bearings by way of a ring-shaped support element (19). A piston with a piston top (11) results which is capable of resisting high combustion space pressures.

Piston for a reciprocating piston internal combustion engine

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.

Diesel internal combustion engine

A liquid-cooled individual cylinder head for piston internal combustion engines with two inlet valves and two outlet valves arranged respectively adjacent one another, which consists of a cast upper part and of a double-walled bottom between the upper part and the combustion space, which is provided with apertures for the valves and for an injection nozzle or a pre-chamber; the bottom extends over the entire surface of the cylinder head upper part up to the outer boundary thereof while the lower surface of the upper part and both surfaces of the bottom are constructed planar; the two parts of the bottom are supported with respect to one another by wall portions or ribs within an annular zone in the area of the support of the bottom on the cylinder head seal while several cooling medium inlet openings are distributed in the lower wall of the double-walled bottom between the annular zone and an outer boundary.
