Joined connection on a two-part piston and joining method

A piston, in particular, a gallery-cooled piston for an internal combustion engine has a piston bottom part and a piston upper part which are connected in a joining process to produce the piston. The piston upper part has at least one ring zone and an inner wall. ... Ks Kolbenschmidt Gmbh

Functionally optimized design of a cylinder liner

A cylinder of an internal combustion engine, in which cylinder liner an oscillating piston is guided on a running surface wherein the cylinder line is fixed vertically by means of a collar between a cylinder housing and a cylinder head. The wet cylinder includes an outer side which deviates from a circular shape and/or a rotationally asymmetrical outer contour of the collar. ... Ks Kolbenschmidt Gmbh

Piston of two-piece construction for an internal combustion engine

A piston for an internal combustion engine, configured as a gallery-cooled piston of two-piece construction includes a main body and a ring element. The ring element which has a ring zone and a fire land encloses a cooling gallery on the outside, which cooling gallery is delimited on the inside by an intermediate wall which separates the cooling gallery from a combustion chamber recess which is made in a piston head of the main body. ...

Layer-by-layer production method during laser melting (sls) in gravity die casting operations

The invention relates to the use of direct metal laser sintering (dmls) for the production of a casting mold, in particular a permanent mold, in order to avoid air pockets in internal combustion engine pistons manufactured in a gravity die casting process, wherein at least one portion of the casting mold has a plurality of small openings, in particular microscopic holes, for discharging air. The invention also relates to a method for producing a casting mold, in particular a permanent mold, for gravity die casting pistons for internal combustion engines.. ... Ks Kolbenschmidt Gmbh

Method of producing a cooling channel system for internal combustion engines and piston produced in this way

A method for producing a cooling channel system for an internal combustion engine, which has a cooling channel in the piston crown. The piston crown is adjoined by a lower piston part having a piston boss, pin bores and piston skirts. ... Ks Kolbenschmidt Gmbh

Gap geometry in a cohesively joined cooling-channel piston

The invention relates to a cooling-channel piston for an internal combustion engine, having an upper part and a lower part, wherein the upper part and the lower part are connected to one another by way of a cohesive joint in the form of a weld seam, and the upper part and the lower part form an annularly encircling cooling channel which is arranged approximately behind a ring section, wherein a gap geometry is provided between a lower edge of the ring section and an upper edge of the lower part, wherein the gap geometry has at least one sliding surface which is arranged on a lower edge of the ring section of the cooling-channel piston and/or on the corresponding upper edge of the lower part of the cooling-channel piston, and to several methods for the operation of a cooling-channel piston.. . ... Ks Kolbenschmidt Gmbh

Piston with low overall height

A piston for an internal combustion engine having an upper part joined by a positive material connection to a lower part, wherein the lower part includes a skirt and at least one pin bore, wherein the upper part includes a combustion bowl and a piston crown with a crown edge, wherein at least one joining point is located in the area of a ring belt and/or in an outer wall of the combustion bowl. A method for producing a piston for internal combustion engines is disclosed.. ... Ks Kolbenschmidt Gmbh

Pistion without a closed cooling chamber for internal combustion engines with at least one cooling oil nozzle per cylinder and method for cooling said piston

An internal combustion engine piston having a cooling chamber open to in a direction toward of pin boss bores. In one example, a shaft separates an inner form of a cooling chamber and a cooling pocket. ... Ks Kolbenschmidt Gmbh

Piston with an open cooling chamber having a flow-effective oil guiding surface and method for cooling said piston

An internal combustion engine piston having a cooling chamber open to in a direction toward of pin boss bores. The cooling chamber having at least one oil guiding surface having a slope. ... Ks Kolbenschmidt Gmbh

Elongate cooling channel inlet for cooling channel pistons and method for operating

The invention relates to a piston in particular for an internal combustion engine, having a piston lower part, an upper part, an internal cooling channel having at least one coolant inlet opening and at least one outlet opening defined by a rim hole. The rim hole having a screw thread into which at least one tubular element is inserted and selectively positioned relative to the cooling channel for regulating the coolant level in a cooling channel.. ...
