Embodiment Construction

[0053] figure 1 An embodiment of a pre-chamber 1 of an internal combustion engine 2 is shown, wherein said pre-chamber 1 is figure 1 a) is shown in the first longitudinal section plane, and at figure 1 In b) it is shown in half section in a second longitudinal section plane rotated about the longitudinal axis relative to the first longitudinal section plane. The pre-chamber 1 for the internal combustion engine 2 has a surface 3 through which the pre-chamber 1 is in operation, which is arranged in the interior 5 of the pre-chamber 1 . The flow-through surface 3 has a first surface region 7 and a second surface region 9, wherein the first surface region 7 has specific structures 11, and wherein the second surface region 9 is free of the structures 11, wherein , the structure therefore does not have the defined structure 11 . Preferably, the surface 3 is not structured and / or smooth in the second surface region 9 .

[0054] The second surface area 9 is preferably - seen in th...

Abstract

The invention relates to a prechamber (1) for an internal combustion engine (2), comprising a surface (3) that is situated in the interior (5) of the prechamber (1) and that is impinged by a flow during the operation of the prechamber (1). According to the invention, the surface (3) has at least one first surface region (7) and at least one second surface region (9), wherein the first surface region (7) has a defined texture (11), whereas the second surface region (9) is untextured (11).

Description

technical field [0001] The invention relates to a pre-chamber for an internal combustion engine, an internal combustion engine having such a pre-chamber and a method for designing and / or producing such a pre-chamber. Background technique [0002] Especially in gas motors operating with a lean combustion air-fuel mixture, ignition enhancers are used starting from a specific bore size of the cylinder, typically more than 100 mm, in order to maintain the combustion rate, center of gravity, at the desired level The position and thus the achieved motor efficiency. As an ignition booster, a pre-chamber is typically used, in which the mixture is pre-ignited by means of an ignition device in a volume separate from the main combustion chamber but connected to it via a so-called injection channel, wherein The ignition creates an overpressure in the pre-chamber relative to the main combustion chamber, so that very hot reaction products and unburned mixture flow from the pre-chamber in...
