Abstract

A fuel-injection system for internal combustion engines has at least one fuel injector injecting fuel into a combustion chamber, which is delimited by a cylinder wall in which a piston is guided. A spark plug projects into the combustion chamber, and the fuel injector is located in the combustion chamber in the region of a gas-intake valve toward the cylinder wall. The fuel injector produces a plurality of fuel jets at least one of these fuel jets being tangentially oriented to the region of the spark plug.
