Cummins
Cummins’ named QSK diesel sets span 600–3,500 kW standby, with separate Data Center Continuous ratings. QSK95 reaches 2,500–3,350 kW DCC. Cummins approves HHP diesel sets for HVO; HSK78 and QSK60 natural-gas units serve prime-power projects.
Facts
Source per value- Smallest unit kW Lowest published electrical output of one generating unit in the named Lines, in kWe. Portfolio minima may include portable models. Standby where available; kVA-only figures assume 0.8 power factor. Consult Rating basis and scope; blank when unverified.
- 600 7
- Largest unit kW Highest published electrical output of one generating unit in the named Lines, in kWe. Standby where available; other duty and frequency bases are disclosed in Rating basis and scope. kVA-only figures assume 0.8 power factor. Mechanical output and multi-unit totals are excluded.
- 3,500 4
- Prime mover What turns the alternator in the named lines: a reciprocating (piston) engine, a gas turbine, or both.
- Reciprocating engine 1
- Fuels Fuels the vendor lists for the named lines: diesel, HVO (hydrotreated vegetable oil, EN 15940), natural gas, biogas, propane, hydrogen blends.
- Diesel; HVO (HHP diesel sets); Natural gas (HSK78 and QSK60 gas sets) 4
- Natural gas units The vendor sells gas-fired units (natural gas, pipeline gas or LNG) in the named lines, for standby, prime or bridge power.
- Yes 1
- HVO approved The vendor states that the named diesel lines are approved or released for HVO (renewable diesel, EN 15940 paraffinic fuel). Blank means no such statement was found on the pages read.
- Yes 4
- Hydrogen Hydrogen capability exactly as the vendor states it: blend share by volume, '100% hydrogen' or 'hydrogen-ready' with its conditions. Blank when the vendor states none.
- Not published
- Hydrogen-capable At least one named line runs on a hydrogen blend or is sold as hydrogen-ready, per the vendor. Read the Hydrogen field for the share and conditions.
- Not published
- Emissions certification Emissions standards the vendor names for the named lines: US EPA Tier 2 (emergency standby) or Tier 4 Final, EU Stage V, TA Luft, CPCB IV+ (India). Certifications vary by model and market.
- Not published
- EPA Tier 4 Final At least one named line is offered as EPA Tier 4 Final certified (engine or genset). Blank means the vendor's pages do not say.
- Not published
- EU Stage V At least one named model is offered as EU Stage V compliant according to the manufacturer. Version and market matter; a blank cell means the cited material did not establish this field.
- Not published
- Engines Whether the vendor builds the engine or turbine itself or packages engines bought from another maker, per the vendor's own pages.
- Own engines 1
- Data center offer Dedicated: the vendor names a product line or program for data centers. General: a standard range the vendor documents in data center use. Rental: the vendor rents fleet units for data center bridge or backup power.
- Dedicated data center line 4
- Lines The product series this record covers. Ratings, fuels and emissions refer to these lines, not to the vendor's whole portfolio.
- QSK23, QSK38 Centum, QSK50, QSK60, QSK78 Centum and QSK95 diesel; HSK78 (C2000N6CD) and QSK60 (C1400N6) natural gas 4
