摘要: In a method for controlling an inlet valve of an internal combustion engine having at least one cylinder with at least a first inlet valve and a second inlet valve, wherein the closing time of the first inlet valve is adjustable and the first inlet valve is so controlled that, at a first engine speed, the first inlet valve is closed before the closing of the second inlet valve and, at a second engine speed which is higher than the first engine speed, the first inlet valve is closed after the closing time of the second inlet valve.

摘要: In internal combustion engines with direct fuel injection an injector injects fuel into the combustion chamber to form an ignitable fuel/air mixture with separately supplied combustion air, with the mixture to be ignited by a spark plug. The fuel is injected in a cone shape and the electrodes are protected from being wetted with fuel and coking if they are disposed outside the lateral surface of the conical fuel jet generated by the injection nozzle. In order to bring ignitable mixture between the electrodes and to ensure optimal operating behavior of the internal combustion engine by improving the combustion sequence, a combustion chamber configuration is provided such that the conical fuel jet is injected in a free jet which is substantially uninfluenced by the combustion chamber perimeter, and the electrodes of the spark plug project into a fuel vortex extending from the lateral surface during injection.
