Xi'an Cummins QSM11-C290 Industrial EngineProduct Description
If you're sourcing a replacement engine for your excavator, crane, or loader — or building a new power pack from scratch; the QSM11-C290 is one of the most battle-tested construction engines on the market.
This isn't a rebranded knockoff. The QSM11-C290 is manufactured at the Xi'an Cummins Engine Co. (XCEC) — a joint venture plant that's been running since 1986, with Cummins USA holding 50% equity. Same technology. Same production standards. Fraction of the OEM dealer markup.

Why Buy From Us, Not the Other 9 Results You Just Googled?
Most suppliers copy-paste the same spec sheet you just read. Here's what actually matters when you're spending this kind of money:
Genuine XCEC Origin; Every engine ships with factory documentation, CPL code verification, and serial number traceable back to the Xi'an plant.
Parts Are Available ; A lot of suppliers disappear after the sale. We stock QSM11 parts and can supply power packs. If something goes wrong six months in, you're not stranded.
15 Business Days, Not 15 Weeks; We maintain inventory. Your quote will include a confirmed lead time, not a guess.
Need More Power? The QSM11-C Family Has You Covered.
The QSM11-C290 is the entry point of the QSM11-C series. Same 10.8L block, same Celect Electronic fuel system, same proven architecture — scaled to match different machine requirements and emission regulations.
If your application demands more torque headroom, higher duty cycles, or a specific emission tier, here's the full picture:
| Engine Model | Rated Speed | Output Power | Peak Torque | Compression Ratio | Emission |
|---|---|---|---|---|---|
| QSM11-C290 ✦ | 2100 RPM | 290 HP | 983 N·m | 16.3:1 | Euro Stage III |
| QSM11-C290-II | 2100 RPM | 290 HP | 1,478 N·m | 16.3:1 | Euro Stage II |
| QSM11-C300 | 2100 RPM | 300 HP | 1,017 N·m | 16.3:1 | Euro Stage III |
| QSM11-C300-II | 2000 RPM | 300 HP | 1,575 N·m | 16.3:1 | Euro Stage II |
| QSM11-C335 | 2100 RPM | 335 HP | 1,036 N·m | 16.3:1 | Euro Stage III |
| QSM11-C335-II | 2100 RPM | 335 HP | 1,674 N·m | 16.3:1 | Euro Stage II |
| QSM11-C335-IV | 2100 RPM | 335 HP | 1,674 N·m | 16.3:1 | Euro Stage IV |
| QSM11-C400 | 2100 RPM | 400 HP | 1,356 N·m | 16.3:1 | Euro Stage III |
| QSM11-C400-II | 2000 RPM | 400 HP | 1,898 N·m | 16.3:1 | Euro Stage II |
| QSM11-C400-IV | 2100 RPM | 400 HP | 1,898 N·m | 16.3:1 | Euro Stage IV |
| QSM11-C400-V | 2100 RPM | 400 HP | 1,898 N·m | 16.3:1 | Euro Stage V |
| QSM11-C420 | 1900 RPM | 420 HP | 1,898 N·m | 16.2:1 | — |
Three things worth noticing in this table:
① Same power output, very different torque
The C290 and C290-II both deliver 290HP, but the -II variant produces 1478 N·m versus 983 N·m on the standard version. If your machine operates under sustained heavy load (deep excavation, uphill dozing), the -II isn't an upgrade, it's the correct spec.
② The C400 family covers four emission tiers
Stage II through Stage V, all on the same block. This matters if you're supplying into multiple markets or future-proofing a fleet purchase.
③ The C420 runs at 1900 RPM, not 2100
Lower rated speed means different torque characteristics and thermal behaviour. Not a drop-in swap for C400 applications — worth a conversation with our team before spec-ing it in.
Which Version Do You Need?
The QSM11-C290 engine block is identical across emission tiers. What changes is the after-treatment system and ECU calibration.
