Abstract: A turbocharger with at least one axial turbine stage. Separate circumferential sections of the turbine are fed by separate exhaust system runners. The turbine is designed to harness pulse energy. Corresponding engine having cylinders comprising such a turbocharger.

Abstract: A method of manufacturing multilayer actuators is described, in which films (1), known as green films, having regions applied thereon made of metal plating to implement electrodes, are processed into compressed multilayer composite elements before a sintering step. Film elements (4), whose area defines the cross-sectional area of a finished actuator, are individually separated from the green film (1) having metal plating and stacked into a film stack to prepare for the manufacture of a multilayer composite element. Furthermore, a device having separating means (31, 32, 33, 35) for performing the method is described, in which the separating means is designed for the purpose of individually separating film elements (4), whose area defines the cross-sectional area of a finished actuator, from the green film (1) and stacking the separated film elements (4) directly afterward.
