The invention relates to an internal combustion engine that comprises a first Brayton cycle comprising a mixed ionic-electronic conducting (MIEC) membrane that separates the Ofrom the air such that the suctioned air current is free from N; a second Brayton cycle combined in a binary manner with the first Brayton cycle and nested with a cycle selected from an Otto cycle and a diesel cycle performed by means of oxy-combustion. The second Brayton cycle transmits mechanical energy and thermal energy from exhaust gases to the first Brayton cycle. The first Brayton cycle provides to the second Brayton cycle compressed Ofrom the MIEC membrane. By means of the present engine, the NOx emission into the atmosphere is prevented by the separation of Nin the MIEC membrane.

Internal combustion engine and operating method of same

The invention relates to an atmosphere conditioning device for testing engines, comprising an inflow conduit connected to an engine admission, an outflow conduit connected to the exhaust of the engine and expelling exhaust gases, a communication conduit which communicates the inflow conduit with the outflow conduit, a supercharging turbogenerator comprising a turbine in the inflow conduit, a bypass valve which diverts the air flow that circulates towards the turbine, a heat regenerator consisting of heat exchangers in the inflow and outflow conduits, connected by the same heat transfer fluid circuit, a bypass valve in the outflow conduit together with the heat exchanger thereof, a heat exchanger in the outflow conduit downstream from the heat regenerator, and a turbocompressor downstream from the heat exchanger.

Device for atmosphere conditioning for testing combustion engines, and associated method and use

An EGR valve assembly includes an intake gas passage, an exhaust gas passage, an outlet passage, a movable intake gas flap for changing an effective cross section of the intake gas passage and a movable exhaust gas flap for changing an effective cross section of the exhaust gas passage. The intake gas flap includes at least one channel connecting an inlet port on a upstream-side surface of the flap with an outlet port on a downstream-side surface of the flap.

The invention relates to a unit for simulating the pressure and temperature conditions of an air flow drawn in by a reciprocating internal combustion engine () at a height above sea level, corresponding to the operating height of said reciprocating internal combustion engine (). According to the invention, the unit comprises at least: (a) a radial inward-flow turbine () for expanding an air flow towards the pressure and temperature of the air drawn in by the reciprocating internal combustion engine; (b) a first container () and (c) a second container () connected to the first container () by means of at least a connection pipe () in order to balance the pressure between the two containers; (d) a centrifugal compressor (); and (e) a vacuum pump () for maintaining a pressure equal to the pressure of the air flow drawn in by the reciprocating internal combustion engine (). The invention also relates to the use of said unit for simulating the pressure and temperature conditions of the air drawn in by a reciprocating internal combustion engine.
