Zhejiang Xingyue Industry – other nonroad diesel engines: the collective page of the single-cylinder small diesels DH178FA and DH186FA from Zhejiang, 4 to 6 kW, Tier 4 Final
This page gathers the Zhejiang Xingyue Industry nonroad diesel engines the register could not assign to a named range from the US EPA certification data. Zhejiang Xingyue Industry is a Chinese maker of small diesel engines based in Zhejiang province; the type designations DH178FA and DH186FA follow the 178F/186F frame-size naming common in this market segment for air-cooled single-cylinder small diesels, and the EPA engine-family code shows a displacement of 0.42 litres for both versions.

The register lists here 2 versions with 4 to 6 kW rated output at 3,600 rpm, from a single cylinder with a 78 to 86 mm bore and 64 to 72 mm stroke – with a stroke-to-bore ratio under 1, a short-stroke design. The engines carry direct injection, run on low-sulphur diesel (300 to 500 ppm) and reach maximum torques of 10.6 to 15.9 Nm at 3,600 rpm. They were certified to Tier 4 (Final or Phase-in), for use outside California only.
Small, high-speed single-cylinder diesel engines of this power class under 8 kW classically drive portable generator sets, water pumps and simple farm equipment, where a simple, air-cooled design without a water-cooling circuit is wanted; such small diesel engines are built by numerous closely related makers across China's coastal provinces.
When buying used, on these single-cylinder engines the condition of the cooling fins and fan wheel, compression, and the condition of the injection pump and nozzle matter; uneven running often points to wear in the injection system. Spares run through Xingyue's Chinese distribution.
