Abstract

Es wird ein Bauteil eines Verbrennungsmotors, insbesondere ein Einspritzsystem oder ein Einspritzventil, mit einem tribologisch beanspruchten Bauelement (10), insbesondere einer Einspritznadel, mit einem sich bei Betrieb relativ zu einem Gegenkörper (11) bewegenden und dabei tribologisch beanspruchten Oberflächenbereich (12) vorgeschlagen, wobei der Oberflächenbereich (12) eine zumindest weitgehend anorganische Hartstoffbeschichtung (14) aufweist. Das Bauteil eignet sich besonders zum Einsatz in einem mit einem trockenen Gas wie Ergas oder Wasserstoff als Brennstoff oder einem unter ölfreien und/oder wasserfreien Verbrennungsbedingungen betriebenen Verbrennungsmotor. Daneben wird ein Gasmotor mit einem derartigen Bauteil vorgeschlagen.

Figure 00000001
A component of an internal combustion engine, in particular an injection system or an injection valve, is proposed with a tribologically stressed component (10), in particular an injection needle, with a surface region (12) which moves relative to a counterbody (11) and is tribologically stressed during operation. wherein the surface region (12) has an at least largely inorganic hard material coating (14). The component is particularly suitable for use in an internal combustion engine operated with a dry gas such as natural gas or hydrogen as fuel or under an oil-free and / or anhydrous combustion conditions. In addition, a gas engine is proposed with such a component.
