Winsun Power – other nonroad diesel engines: the EPA register of the 188FB single-cylinder and R2V840 V-twin, 2012 model year, Tier 4 from below 8 to below 19 kW
The US EPA classifies small diesel engines for mobile equipment by power category; Winsun Power offers the 188FB, a horizontal single-cylinder, and the R2V840, a V-twin, neither of which the register could assign to a named range. The single-cylinder falls into the EPA category below 8 kW, the twin-cylinder into the 8 to below 19 kW category, both in the Tier 4 (Final or Phase-in) emission stage.

The register lists here 2 versions from the 2012 model year, with 7 to 12 kW rated output at a constant 3,600 rpm and 86 to 88 mm bore with 72 to 75 mm stroke – short-stroke in design. Maximum torque ranges from 18.4 to 33.3 Nm, again at 3,600 rpm; both versions run direct injection and low-sulphur diesel with 300 to 500 ppm sulphur content.
The single-cylinder suits portable generator sets and water pumps, while the V-twin suits larger units where two cylinders give smoother running; both layouts belong to the standard repertoire of Chinese small-diesel manufacturers exporting to the US market.
When buying used, on the single-cylinder what counts is the tightness of the injection pump, and on the V-twin additionally the even running of both cylinders and the tightness of the cylinder-head gaskets; corrosion on the fuel tank and frame is common on generator sets run outdoors. Spare parts for these engine formats are available through the general trade for Chinese small diesel engines.
