    • In a method of operating an internal combustion engine with a switch-over capability between a compression ignition mode of operation and a spark ignition mode of operation in higher load ranges which includes a cam-operated valve drive with a valve control providing, in the compression ignition mode of operation, for an increased valve overlap of the valve opening times, smooth engine operation and optimal exhaust gas emissions are obtained also during rapid load changes upon changing the engine operating mode as the change-over is accompanied by changes of the injection parameters, the throttling parameter and the valve control, which are coordinated with respect to one another as the valve control is switched over by changing the amplitude and phase position of the valve stroke of at least one of the inlet and outlet valves.
    • 在具有压缩点火操作模式和在较高负载范围内的火花点火操作模式之间具有切换能力的内燃机的方法中,所述方法包括具有阀控制的凸轮操作阀驱动器,所述阀控制器在压缩 点火操作模式,在改变发动机工作模式时,在快速负载变化时也可以获得阀门打开时间的阀门重叠增加,发动机运行平稳和最佳废气排放,因为转换伴随着喷射参数的变化 ,节流参数和阀门控制,其通过改变入口阀和出口阀中的至少一个的阀行程的振幅和相位位置来切换阀控制,从而彼此协调。
