Abstract
An internal combustion engine includes a first injector and a second injector for injecting fuel directly into a combustion chamber in a cylinder in a crank case of the internal combustion engine. The combustion chamber is delimited at one side by a piston which is arranged in the cylinder so as to carry out a stroke and at the other side by a cylinder head. At least one gas exchange inlet valve and a gas exchange outlet valve are provided in the cylinder head for a charge exchange. The first injector is largely oriented in the direction of a cylinder axis, and the second injector is oriented at an angle to the cylinder axis. Maximally 80% of a full-load fuel quantity required by the internal combustion engine for a full load can be introduced into the cylinder using the first injector and maximally 50% using the second injector. The injectors can be configured for smaller fuel flow rates using the internal combustion engine design and operating method, whereby the precision of the injection is improved.
