Baudouin – other nonroad diesel engines: the collective page of the current M33/M55/M61 certifications from model years 2023 to 2026 outside the named models, 633 to 4,850 kW
Baudouin, the French large-diesel maker from Marseille with a majority stake held by the Chinese Weichai group, continuously recertifies its M33, M55 and M61 V-engine ranges with the US EPA; the certifications listed here come from model years 2023 to 2026 and are thus the most current generation of Baudouin's large engines in the register. As with other currently certified ranges, each of the nine models carries several EPA engine-family codes at once, indicating parallel equipment or market variants of the same base engine.

The register lists here 9 versions with 633 to 4,850 kW rated output at 1,500 to 1,800 rpm, from six- to twenty-cylinders, mostly in V configuration (8 of 9), with 150 to 190 mm bore and 185 to 215 mm stroke. Maximum torque ranges from 4,030 to 30,878 Nm. All engines have fixed turbocharging and direct injection, run on low-sulphur diesel and are certified to Tier 2; the 560 to 2,237 kW power category forms the majority with 5 of 9 versions.
As the current generation of Baudouin's large engines, these versions drive standby generator sets, ship propulsion and power-plant installations, in a market segment increasingly shaped by Chinese drive technology since the Weichai stake.
On a used purchase, operating hours and the service history of the injection system, the condition of the turbocharging, cooling system and charge-air cooler, and the tightness of crankshaft seals and cylinder-head gaskets all matter; since several engine-family codes are carried per model, it is worth checking parts against the specific nameplate. Spares run through Baudouin service.
