Abstract (en)

The present disclosure relates to a pre-combustion chamber assembly (60) for internal combustion engines operating at least partly on gaseous fuel. In case of an additional gaseous fuel supply within the pre-combustion chamber assembly (60), an ignition device is required to be displaced out of center due to a lack of installation place in a central region. Thus, the disclosed pre-combustion chamber assembly (60) may comprise a pre-combustion chamber main portion (92) having a main portion central axis (93) that may extend in parallel to pre-combustion chamber assembly longitudinal central axis (63) with a predetermined offset (91). The pre-combustion chamber assembly (60) may further comprise an ignition device configured to initiate a combustion event at an ignition point (99) within the main portion (92). The ignition point (99) may lie substantially on the main portion central axis (93).
