Problems solved by technology

[0005] A problem in the prior art is that a so-called damage volume 19 is formed between the front section 18 of the piston 10 leading on the flame ring 12 and the flame ring 12 , in which damage volumes can accumulate fuel, which in the combustion chamber does not or incompletely burns in the combustion chamber 14
This limits the efficiency of the internal combustion engine

Embodiment Construction

[0017] The invention here relates to a piston of an internal combustion engine, in particular an internal combustion engine designed as a diesel motor or a gas motor or a diesel gas motor, for example a marine diesel internal combustion engine. Such a piston is also called a plunger.

[0018] figure 2 and 3 A detail of a piston 20 according to the invention is shown according to a first embodiment of the invention. Piston 20 can be a piston that is composed or constructed from a piston upper part and a piston lower part or, alternatively, a so-called one-piece piston.

[0019] If referring to the constructed piston, then in figure 2 and 3 The piston body 21 shown in refers to the piston upper part of the constructed piston 20 .

[0020] The piston body 21 of the piston 20 (in the case of the constructed piston, the piston upper part of the piston) has at the front, viewed in the axial direction, a piston bottom 22 which delimits in sections the combustion chamber of the...

Abstract

A piston (20) for a cylinder of a combustion engine, having a piston body (21) with a defined outer diameter and an axially forward piston head (22) that defines parts of a combustion chamber of the cylinder, wherein at the radially outer edge of the piston body (21) the piston head (22) is extended axially rearwards and reduces the wall thickness of the piston body.

Description

technical field [0001] The invention relates to a piston of an internal combustion engine according to the preamble of claim 1 . Background technique [0002] The piston of the internal combustion engine can be designed as a so-called structural piston consisting of a piston upper part and a piston lower part or as a so-called monolithic piston. Correspondingly constructed pistons are known from DE 35 18 721 C2 and from DE 10 2005 013 087 B3, which consist of a piston upper part and a piston lower part, wherein the piston upper part has an axially forward piston bottom and a cylindrical the outer wall. So-called combustion chamber pockets can be formed on the piston base in the radially inner region of the piston base. The cylindrical outer wall has grooves for receiving piston rings. Such a piston of an internal combustion engine is guided in a cylinder running sleeve of a cylinder block of the internal combustion engine, wherein DE 101 21 852 C2 shows the basic structur...
