Abstract
A fuel injection system (1) for internal combustion engines has at least one fuel injector (7) which injects fuel into a combustion chamber (6) delimited by a cylinder wall (2) in which a piston (3) is guided, and it has a spark plug (8) which protrudes into the combustion space (6), and the fuel injector (7) is designed so that a conical spray jet (13) is produced in the combustion chamber (6). The conical spray jet (13) has an angle cutout (17) in the area of the spark plug (8).
Claims11
A fuel injection system (1) for internal combustion engines having at least one fuel injector (7), which injects fuel into a combustion chamber (6) which is delimited by a cylinder wall (2) in which a piston (3) is guided, and having a spark plug (8) which extends into the combustion space (6), the fuel injector (7) being designed so that a conical spray jet (13) is produced in the combustion chamber (6),
- wherein the conical spray jet (13) has an angle cutout (17) in the area of the spark plug (8).
A method of injecting fuel into a combustion chamber (6) of an internal combustion engine by using a fuel injector (7) which is delimited by a cylinder wall (2) in which a piston (3) is guided, with a spark plug (8) projecting into the combustion chamber (6) and a conical injection jet (13) being produced by the fuel injector (7),
- wherein the conical injection jet (13) has an angle cutout (17) in the area of the spark plug (8).
