Fuzhou Kapur Power Equipment – other nonroad diesel engines: the collective page of EPA-certified single-cylinder 178F and 186F series outside the named ranges, 4 to 6 kW from Fuzhou, China
Fuzhou Kapur Power Equipment, based in the Chinese city of Fuzhou, certifies small air-cooled single-cylinder diesel engines with the US EPA for generator sets and work equipment. This page gathers the KD178FA and KD186FA versions that the register could not assign to a named range. The type numbers 178 and 186 match the cylinder bores of 78 and 86 mm listed in the register; both versions share the same EPA engine family CFZKL.418F86.

The register lists here 2 versions with 4 to 6 kW rated output at a constant 3,600 rpm, from single-cylinders with 78 to 86 mm bore and 62 to 72 mm stroke – short-stroke in design, as the stroke stays shorter than the bore. Both run direct injection and low-sulphur diesel (300 to 500 ppm), certified to Tier 4 (Final or Phase-in) in the EPA power category below 8 kW. Maximum torque ranges from 11.3 to 12.3 Nm, again at 3,600 rpm, with certification covering states outside California.
Engines of this type mainly drive portable generator sets, water pumps and small construction equipment, where low weight and simple maintenance matter more than high output per litre. The 178F/186F format is among the most widely built small-diesel platforms worldwide and forms the basis for engines from numerous Chinese manufacturers with a similar layout.
When buying used, what counts on these air-cooled single-cylinders is the condition of the cooling fins and fan wheel, the tightness of the injection pump, and the action of the decompression lever where fitted; corrosion on the fuel tank and frame is common on generator sets run outdoors. Spare parts for this widely used format are available through the general trade for Chinese small diesel engines.
