FUEL-INJECTION SYSTEM

摘要

The invention relates to a fuel-injection system for the direct injection of fuel into a combustion chamber (38) through the ceiling (39) of said chamber, which lies opposite a piston (40). Said system comprises a fuel-injection valve (1) with a valve closing body (4) that can be actuated. The valve closing body (4) co-operates with a valve seat surface (6) to form a seal seat. A spray mist (42) is produced by means of a plurality of injection orifices (7), a fuel jet (41) being produced by each respective injection orifice (7) and the plurality of fuel jets (41) in the combustion chamber (38) constituting the spray mist (42). A first flare angle (a1) of the spray mist (42) on a first plane (e1) is greater than a second flare angle (a2) on a second plane (e2) that runs perpendicularly to the first plane (e1).
