Weichai – other nonroad diesel engines: the collective page of EPA-certified M33 large engines outside the named ranges, 616 to 1,680 kW, six- to sixteen-cylinder, model years 2020 to 2025, Tier 2
Weichai, headquartered in Weifang, Shandong, is one of China's largest diesel engine makers, with a range spanning small agricultural-machinery engines to large units for ships and power plants. The versions listed here, 6M33, 12M33 and 16M33, belong to the M33 range, named after the cylinder count and the M33 range designation. This page gathers the models outside the named ranges.

The register lists here 3 versions with 616 to 1,680 kW rated output, all at 1,800 rpm, from six- to sixteen-cylinder with 150 mm bore and 185 mm stroke. Maximum torque ranges from 3,267 to 8,912 Nm, model years from 2020 to 2025; all three versions run a fixed-geometry turbocharger and direct injection at the Tier 2 emission stage and the above 560 kW power category.
The more recent model years of these M33 versions show that Weichai kept developing the large-engine range after 2020 for nonroad use in standby generator sets and heavy stationary plant, while the Tier 2 emission stage points to certification for less emission-regulated application areas.
On a used purchase, operating hours count, along with the condition of the turbocharger, the tightness of the charge-air ducting and the service history of the injection system; on engines of this power class, parts supply through authorised Weichai representatives is decisive for uptime.
