Cummins M11 and QSM11
The 10.8-litre family listed from the M11-C310 at 228 kW, with the QSM11 listed within the same family entry.
The M11 family's listed table starts at the M11-C310 at 228 kW, inside a family band of 228–298 kW, on bore and stroke of 125 × 147 mm and a displacement of 10.8 litres, at 2,100 rpm. The QSM11 is listed within the same family entry — the catalogue treats M11 and QSM11 as one family page with the M11 variants tabulated. That is how this page presents them: one family, the M11 rows on record, and the QSM11 named as the variant line whose per-variant rows are not tabulated — ask for them by designation.
The M11 class sits between the C family (6CT/C8.3) and the 19-litre K families, a span where engines serve heavy trucks' industrial derivatives, construction machines, and mid-large gensets. Buyers arriving from a machine plate should read the variant code carefully — in this family the code (for example C310) carries the rating step, and quoting 'M11' alone spans a 70 kW band.

Specifying an M11
Use the variant code as the primary key. If your plate reads M11-C310, the listed entry row (228 kW at 2,100 rpm) is your reference; other steps in the 228–298 kW band correspond to other codes — ask for the row for your code to be stated in the quote. For QSM11 enquiries, state the full QSM11 designation — the family entry names the line, and its variant rows must come from the QSM11's own record, not from the M11 table — ask for them by designation.
For genset use, apply the same rule as the other machine-table families on this site: the listed M11 figures are at 2,100 rpm working speeds, so state your frequency and duty and have the genset-appropriate variant and rating confirmed instead of transposing the machine row.
