Patent ID: 7392796

Claim:
An operating method for an internal combustion engine, representing a closed thermodynamic cycle that includes steps of isochoric, isobaric heat input during combustion, adiabatic expansion of gases, isochoric heat removal at the moment of their discharge and adiabatic compression, wherein the internal combustion engine and a swirl energetic separation chamber ( 10 ) incorporate a single interdependent thermodynamic system with a single closed volume, comprising the steps of: a) discharging exhaust gases through a tangential nozzle into the swirl energetic separation chamber ( 10 ) of the internal combustion engine to form a swirling gas flow within the swirl energetic separation chamber such that b) the swirling gas flow in the swirl energetic separation chamber separates into a cold paraxial flow with low pressure and a hot swirling flow with high pressure, wherein in the hot swirling flow the exhaust gases are heated up and make irreversible physical-chemical transformations, wherein chemical components of the exhaust gases undergo an aggregative-phase transition, c) compensating and cooling said hot swirling flow through contact with the cold paraxial flow with transformation of common thermodynamic and physical-chemical parameters of the exhaust gases, wherein an aggregative-phase transition of chemical components of the exhaust gases into a state of liquid occurs d) subsequently removing the liquid into a drainage ( 12 ); and e) producing vacuum in the closed volume of the single thermodynamic system and making an additional positive power stroke in the expansion chamber of the internal combustion engine as a vacuum engine.
