Exhaust turbo charger with energy accumulator and energy recovery has drive unit with energy accumulator to store exhaust energy and supply movement energy to compressor shaft

摘要

The device has a turbine (2), a charging air compressor (3), and a drive unit with drive (10) and coupling (7). The unit also has an energy accumulator (6) for the storage of exhaust energy. The shaft (4) of the compressor is supplied with variable volumes of stored exhaust energy, the shape of movement energy, by the drive unit. The energy accumulator is formed by a flywheel mass, or a hydraulic or pneumatic pressure accumulator. The switchable coupling is connected to a controllable hydrodynamic coupling (8), for mechanical or electro-mechanical bridging.
