The register lists 32 variants here rated from 13 to 64 kW at 1,500 to 2,800 rpm, three- to four-cylinder engines with a bore of 78 to 98 mm and a stroke of 82 to 113 mm. Maximum torque ranges from 65 to 336.7 Nm at 1,500 to 2,200 rpm, model years from 2011 to 2022. Among emission tiers, Tier 4 (Final or Phase-in) leads narrowly with 16 variants ahead of Interim Tier 4 with 15 and Tier 3 with one; the 19–37 kW power category is the most common with 19 variants, followed by 37–56 kW and 8–19 kW with 6 each. 29 of the 32 engines are certified for sale in all US states, 3 only outside California.

Engines of this class drive mini-excavators, compact loaders and small generator sets; the parallel line-up of several generations and application variants within the same series designation points to a continuously maintained base design, adapted for different equipment makers over the years.

When buying used, the only 11 turbocharged variants call for a check of boost pressure and turbocharger condition, while the mostly indirect-injection engines additionally need glow plugs and cold-start behaviour checked; oil consumption and the tightness of crankshaft seals also matter. Since model years reach back to 2011, running hours are worth checking too.
