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 (1) at a height above sea level, corresponding to the operating height of said reciprocating internal combustion engine (1). According to the invention, the unit comprises at least: (a) a radial inward-flow turbine (2) 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 (4) and (c) a second container (5) connected to the first container (4) by means of at least a connection pipe (7) in order to balance the pressure between the two containers; (d) a centrifugal compressor (3); and (e) a vacuum pump (6) for maintaining a pressure equal to the pressure of the air flow drawn in by the reciprocating internal combustion engine (1). 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.
