    • 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.
    • 本发明涉及到一个单元,用于模拟由往复运动的内燃发动机(1)在海平面上方的高度吸入的空气流的压力和温度条件下,对应于所述的往复式内燃机的运行高度(1)。 。根据本发明,该单元包括至少:(a)一种径向向心式涡轮(2)扩大到朝向压力和由往复式内燃机吸入的空气的温度的空气流; (B)第一容器(4)和(c)的第二容器(5)连接到所述第一容器(4)通过至少一个连接管的装置(7),以平衡两个容器之间的压力; (D)的离心式压缩机(3); 和(e)用于维持等于空气流的通过往复式内燃机吸入的压力的压力的真空泵(6)(1)。 因此,本发明涉及使用所述单元的用于模拟由往复运动的内燃机吸入的空气的压力和温度条件。
