Abstract (en)

[origin: WO0182983A1] The aim of the invention is to utilize the lost thermal energy as well as acoustic waves and braking energy of combustion engines, primarily to operate motor vehicles, and to purify the exhaust gases of such engines. In a piston engine, the gases = exhaust gases and acoustic waves emerging from the combustion chamber (cylinder) flow through the exhaust duct to a Kaplan turbine: In this turbine, the thermal energy (temperature and pressure of the gases) and the energy of the acoustic waves are converted to mechanical energy. Soot particles, ashes, etc. are accumulated in the Kaplan turbine at off-peak operation of the V-engine by centrifugal forces. The (accumulated) soot, tar etc. is combusted energetically at increased V-engine output by acoustic waves, pressure, heat, friction, chemical and/or catalytic reactions, the exhaust gases and the turbine are purified, the acoustic waves (pressure waves) are positively converted to mechanical energy and are thereby expediently damped with only little losses. In the inner tube of the Kaplan turbine (exhaust inlet) particles are deposited at a low V-engine output inter alia by the centrifugal forces (pre-arrester), thereby substantially preventing (if necessary with catalytic effect) the subsequent gas discharge ducts from being soiled up to the gas discharge. It is further possible, if deemed economical, to utilize the cooling energy in the form of hot gases, vapor etc. in the Kaplan turbine.
