# ChME3 shunting locomotives — PrJSC Zaporizhzhia Iron Ore Plant

**IE S001**  
PrJSC Zaporizhzhia Iron Ore Plant · Ukraine · 2006–2021

Compression and combustion pressure rose, engine vibration dropped, the compressor built up pressure faster. Ukraine · 2006–2021.

## Measured

- cylinder compression, 16-33 → 22-36 kgf/cm² — **11-20 %**
- peak combustion pressure, 20-49 → 29-50 kgf/cm² — **9-17 %**
- air system charging time by the compressor, 30-73 → 26-55 s — **10-23 %**
- engine block vibration velocity, 0.9-11.3 → 0.4-9.1 mm/s — **36-45 %**

## Conclusion

Compression and combustion pressure rose, engine vibration dropped, the compressor built up pressure faster
