Abstract:
1. Device for controlling disconnection of the cylinders in internal combustion engines, comprising at least one control device acting on a switchable element for valve actuation of valves and permitting in one of two switching states an actuation of the valve concerned, including transmission devices which, in dependence on a switch over state of the control device, transmit a cam rise produced by a camshaft to the valve provided with the switchable element, and a control unit acting on the control device, wherein the device has a data memory for detection of a time course of movement behavior of the gas exchange valves of the cylinders of the internal combustion engine, and a data processing unit which provides a combination of gas exchange valves into valve groups with regard to a common activation or deactivation, and passes on to the control unit in which an activation or deactivation instant is allocated to the valve groups, and which drives the control device by which the switchable elements for valve actuation of the valves belonging to the valve group are actuated.
