发明名称 Internal combustion engine with a first and a second injecter
摘要 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.

主权项 1. An internal combustion engine, comprising: a cylinder in a crank case of the internal combustion engine; a combustion chamber in the cylinder, the combustion chamber being delimited on one side by a piston arranged in the cylinder that performs a stroke motion and on another side by a cylinder head; at least one gas exchange inlet valve and one gas exchange outlet valve provided in the cylinder head for a charge exchange; first and second injectors configured to inject fuel directly into the combustion chamber in the cylinder, wherein the first injector is arranged oriented largely in a direction of a cylinder axis of the cylinder, and the second injector is arranged oriented at an angle to the cylinder axis, and a maximum of 80% of a full-load fuel quantity required by the internal combustion engine for a full load is introducible into the cylinder via the first injector and a maximum of 50% of said full-load fuel quantity is introducible via the second injector.
