Abstract

In the event of a failure or a disruption of an exchange of data between a valve control unit and an operational control unit of an internal combustion engine with electromechanically activated inlet valves, a valve control unit switches over the electromagnetic activation of the inlet valves to full-load control times. The operational control unit suitably sets a throttle valve in order to cause the load control of the internal combustion engine no longer to be performed by the valve load control but rather by the throttle-valve load control in the emergency operating mode.
