    摘要： Ignition electrodes (80) having at least one electrode arm (82) may be exposed to high thermal and mechanical stress, which may lead to undesired fails of the material due to the known bending process when manufacturing cross-type ignition electrodes. Therefore, the present disclosure relates to a method for manufacturing an ignition electrode (80) of a spark plug (60) configured to be used in an internal combustion engine (10) and including a pre-combustion chamber (66). The method may comprise providing a mixture of powdered metal and binder material, forming the mixture of powdered metal and binder material into a desired shape, debinding the formed mixture of powdered metal and binder material for driving off the binder material, thereby forming a blank, and sintering the blank.

    摘要： The present disclosure relates to a pre-combustion chamber assembly (60) for internal combustion engines. For reducing excessive wear of both an ignition electrode (80) and an associated mass element (100), the ignition electrode (80) may include at least one electrode arm (82) extending in both at least a radial direction with respect to a longitudinal axis (90) of a pre-chamber (66) and at least an axial direction with respect to the longitudinal axis (90), wherein the mass element (100) includes at least mass protrusion (102) provided with at least one radial inner face (104) facing the ignition electrode (82) and being substantially non-parallel with respect to the longitudinal axis (90).
