BRAKING AND AUXILIARY DRIVING MEANS FOR AN INTERNAL COMBUSTION ENGINE

摘要

In a braking and auxiliary driving means for an internal combustion engine in a vehicle which produces braking and auxiliary motive power by converting electric al energy in both directions between the polyphase AC circuit of a squirrel-cage polyphase induction machine linked to the rotary shaft of the internal combustion engine and the DC circuit of an electricity storage means, the electricity storage means comprises an electrosta tic capacitive circuit. A low-voltage storage battery is provided in addition to this electrost atic capacitive circuit, and this can be coupled to the electrostatic capacitive circuit by a bi directional DC-to-DC converter.
