The invention relates to a fuel injection system for internal combustion engines, comprising, amongst other things, at least one fuel injection valve (4), which injects fuel into a combustion chamber (7), with a spark plug (3), extending into the combustion chamber (7). The fuel injection valve (4) comprises a valve body (10) which has several circumferential injection nozzles (11, 11d). The injection nozzles (11, 11d) are arranged such that a conical injection stream (5) is produced in the combustion chamber (7). At least those injection nozzles (11d) which are directly adjacent to the spark plug (3) comprise an oblong cross-section.
