SSJ100发动机和ARJ21发动机数据对比，看起来ARJ21发动机油耗数据略微差点
SSJ100的发动机是PowerJet SaM146
ARJ21-700的发动机是CF34-10A
SaM146参数
General characteristics
Type: Twin spool, High-bypass turbofan
Length: 2.2 m (87 in)
Diameter: 1.22 m (48 in)
Dry weight: 1,708 kg (3,765 lb) (*)
Components
Compressor: 1 stage fan, 3-stage low pressure, 6-stage high pressure axial compressor
Combustors: Annular
Turbine: 1-stage high pressure, 3-stage low pressure
Fuel type: Jet A, Jet A-1, TS-1, RP (*)
Performance
Maximum thrust: 76.84 kN (17,270 lbf) (*) (Maximum takeoff thrust)
Overall pressure ratio: 23.8:1
Bypass ratio: 4.43:1
Specific fuel consumption: 0.374 lb/lbf-hr (Dry) and 0.629 lb/lbf-hr (Cruise)
Thrust-to-weight ratio: 5.3:1
CF34-10A参数
Thrust 17,640 lbf (78.5 kN)
at sea level
Thrust-to-weight 5.1:1
ratio
Overall pressure ratio 29:01:00
at max. power
Bypass ratio 5:01
Cruise SFC .65 lb/lbf/h (18 g/kN/s)
可以看出SaM146，油耗低一点，最大推力也低一点
整个使用CF34家族发动机的支线客机（0.64--0.69 lb/lbf-hr 之间）看起来，油耗都比SSJ100要高一点

Cruise SFC这个数值，需要标注速度和高度，否则没意义呢。
CF34的巡航点是35000英尺，速度 0.78 M
SAM146，抱歉，我还找不到对应的数据。

涵道比CF34-10A还是大一些，最大推力也占优，因为ARJ21定位高高原，就像737-700可以飞高高原，而737-800就不行，相对来说座公里油耗700比800大很多
SaM146另一个版本【ssj100 95LR 用的】推力比CF34-10A大一些
发动机只是重要的动力系统，还得看整机的系统设计，翼形设计、升阻比、浸润面积、表面阻力和结构重量等等。
SSJ100如果真有机会看到，我一定会想，高层在天上了
