为扩大NR系列增压器的应用范围,TCU公司推出新的NR/R系列(R指后弯压气机叶轮)。该系列的最小型号是NR15/R(图1),对较大功率柴油机可选用容积流量更大的NR20/R和NR26/R型。图2示明NR/R径流同NA/T轴流涡轮增压器的衔接关系,从该图可明显看出径流式增压器外形小的优点。新研制的NR/R系列增压器吸收了早先的NR系列的成功经验。增压器效率可达60％(当压比为2～3.5时则效率高于60％),压气 To expand the range of applications for the NR Series turbochargers, TCU Corporation introduced the new NR / R Series (R-Finger Compressor Turbine). The smallest model in the series is the NR15 / R (Figure 1) and the larger volumetric NR20 / R and NR26 / R models are available for larger diesel engines. Figure 2 shows the convergence of the NR / R runoff with the NA / T axial turbocharger, from which it is evident that the radial turbocharger has the advantage of small form factor. The newly developed NR / R series supercharger incorporates the success of previous NR series. Turbocharger efficiency up to 60% (when the pressure ratio of 2 to 3.5 when the efficiency is higher than 60%), pressure
