Abstract
An internal combustion engine supercharged with air by an exhaust gas-driven turbo-compressor discharging through a by-pass duct a tapped flow rate of compressed air into the exhaust gas pipe-line feeding the turbine, said tapped flow rate of compressed air being heated by means of a heat exchanger inserted into the by-pass duct and through which are flowing the exhaust gases from the turbine, said tapped flow rate of heated compressed air being injected into the upstream end of the exhaust manifold of the engine.
Claims16
A method of producing energy with a power generator, comprising:
- an internal combustion volumetric piston-type motor system, a supercharging air compressor system and an exhaust gas-driven turbo-motor system having mechanical and/or pneumatic couplings therebetween;
- said method consisting in taking a by-passed compressed air flow between the compressor system and the volumetric motor system from the total compressed air flow discharged by said compressor system and adding said by-passed compressed air flow to the exhaust gases of the motor system between the gas outlets of the working cylinders thereof and before the gas outlet of the turbo-motor system as well as in providing an energy supply recovered from the energy derived from the gases burnt within the volumetric motor system to the exhaust gases through the medium of said by-passed compressed air flow, characterized in that the energy supply to said by-passed compressed air flow is effected in the form of heat and mass momentum through the direct mixture of at least the major part of the by-passed compressed air flow with at least one part of the gas flux issuing from said turbo-motor system, in particular through a pumping blast nozzle effect sucking and impelling said gas by means of said compressed air acting as at least one air jet.
A power generating system comprising:
- a piston-type internal combustion volumetric engine system, a supercharging air compressor system and an exhaust gas-driven turbo-motor system with mechanical and/or pneumatic couplings therebetween;
- a by-pass duct connecting the compressed air delivery pipe-line from said compressor system to the exhaust gas flow passage-way of said volumetric motor system after the outlet thereof from the working cylinders of said engine system and a device for recovering energy from the gases burnt within said volumetric engine system and for transferring the recovered energy to one part of the compressed air flow, a compressed air flow passage-way extending through said device which is inserted with its compressed air flow passage-way exclusively in said sole by-pass duct, characterized in that said energy recovery and transfer device consists of at least one ejector the impelled fluid suction pipe of which is branched in by-passing relationship off a gas outlet pipe-line of said turbo-motor system.
