Mitsubishi S6S-DP

The register lists 32 variants here rated from 11 to 2,150 kW at 1,750 to 3,600 rpm, two- to sixteen-cylinder engines (27 inline, 5 V-configuration) with a bore of 76 to 170 mm and a stroke of 70 to 180 mm. Maximum torque ranges from 30 to 9,284 Nm at 1,350 to 2,700 rpm, model years from 2012 to 2024 (final model year up to 2026). The 8–19 kW, 19–37 kW and 37–56 kW power categories are equally represented with 8 variants each, followed by 560–2,237 kW with 6; among emission tiers, Tier 4 (Final or Phase-in) leads narrowly with 13 variants ahead of Interim Tier 4 with 12.

The engine range thus spans small construction machinery units in the low double-digit kW range as well as standby generator sets in the megawatt range; the near-even split across the three lower power categories points to a broadly diversified line-up without one dominant focus.

When buying used, small naturally aspirated engines call for a check of cold-start behaviour and glow plugs, while the large turbocharged V-configuration engines additionally need boost pressure and turbocharger condition checked; oil consumption also matters, and, for engines with model years from 2012 onward, the running hours accumulated so far. Spare parts run through the Mitsubishi dealer network.
