FUEL INJECTION SYSTEM

摘要

The invention relates to a fuel injection system (1) for internal combustion engines, comprising a fuel injection valve (12) that injects the fuel into the combustion chamber (2) that is defined by a cylinder wall (3). A piston (5) is guided inside said cylinder wall (3) and a spark plug (8) projects into the combustion chamber (2). The fuel injection valve (12), by means of at least one row (23) of injection orifices (24) disposed on the periphery of a valve body (20) of the fuel injection valve (12), produces a conical mixed cloud (13). The valve body (20) is additionally provided with a center injection orifice (22) that produces a center portion of the mixed cloud (13) that is directed towards the spark plug (8).
