Stellantis 50D

The register lists here 10 versions with 34 to 54 kW rated output at 2,500 to 2,600 rpm, from three-cylinders with a constant 94 mm bore and 107 mm stroke. Maximum torque ranges from 160 to 250 Nm at 1,800 rpm. All engines have fixed waste-gate turbocharging and common-rail direct injection, run on low-sulphur diesel and are certified to Tier 4 (Final or Phase-in), in the 37 to under 56 kW power category.

The long certification span from 2015 to 2026 shows that this small three-cylinder range stays practically unchanged in the nonroad programme for over a decade; engines of this size drive small construction machinery, compressors, generator sets and small farm implements.

On a used purchase, operating hours count, the condition of the turbocharging and its waste-gate control, the common-rail injectors, and on Tier 4 Final versions the exhaust aftertreatment; since certification ran unchanged across several model years, the exact engine family should be checked against the nameplate when buying parts. Spares run through the Stellantis sales network.
