Abstract
In a method of operating a diesel internal combustion engine, wherein a homogeneous mixture is formed in the combustion space before a spontaneous ignition by means of fuel injected directly into separately supplied combustion air, which combustion air is admitted to the combustion space in a swirling flow about the longitudinal axis of the cylinder that can be adjusted as regards its swirl intensity by a control element. A control unit adjusts the swirl intensity in a manner coordinated with the injection parameters to provide a homogeneous mixture igniting at a predetermined point for highly effective engine operation with low emissions.
