A frame support for a rack or a switchgear cabinet, having an electrification arrangement combined with at least one frame leg or profiled mounting element for supplying andor removing electrical current to or from devices which can be connected with the frame support. Each sample vector is combined with the weight that is estimated for the respective sample vector to provide a plurality of weighted sample vectors. The low-voltage capacitor comprises a first electrode formed from a first metal layer, a second electrode formed from a second metal layer, a third electrode formed from a third metal layer, a first dielectric layer between the first and second electrodes, and a second dielectric layer between the second and third electrodes. The principal surface of the submount member faces the multilayer structure. The engine control unit is arranged to control the opening degree of the valve in accordance with a valve opening speed set based on at least the pressure of the fuel in the fuel pipe when starting the engine.
