Claim 0:
1. A direct-injection, applied-ignition internal combustion engine comprising:
a cylinder head, and a cylinder;
wherein the cylinder has at least one inlet opening for the supply of combustion air via an intake system and at least one outlet opening for the discharge of exhaust gases via an exhaust-gas discharge system;
wherein the cylinder comprises a combustion chamber which is jointly formed by a piston crown of a piston, by a cylinder liner which laterally delimits the combustion chamber, and by the cylinder head, the piston being movable along a piston longitudinal axis between a bottom dead center and a top dead center;
wherein the cylinder is equipped, in a region of the cylinder liner, with an injection device for the direct injection of fuel into the combustion chamber, which injection device has at least one opening which, during the course of an injection process, can be activated for the purposes of introducing fuel into the combustion chamber;
wherein the cylinder is equipped with an additional injection device which is arranged in the cylinder head, the injection device being oriented toward the additional injection device such that a virtual elongation of a longitudinal axis of the injection device forms an obtuse angle α with a virtual elongation of a longitudinal axis of the additional injection device in a projection perpendicular to the piston longitudinal axis; and
wherein, during a same combustion cycle, the injection device is configured to introduce the fuel into the combustion chamber by injecting the fuel in a direction away from the cylinder head, and the additional injection device is configured to introduce further fuel into the combustion chamber by injecting the further fuel in a different direction towards the cylinder head and towards the fuel introduced by the injection device, wherein both the fuel and the further fuel are liquid fuels, and wherein the cylinder is equipped with an ignition device and an additional ignition device initiating the applied ignition.
