Zhejiang Xingyu – other nonroad diesel engines: the collective page of EPA-certified single-cylinder small diesel engines outside the named ranges, 4 to 6 kW, 3,600 rpm, model years 2011 to 2012, Tier 4 Final
Zhejiang Xingyu, headquartered in Zhejiang province, builds small air-cooled diesel engines for agricultural equipment and mobile drives. The versions listed here, 178F, 186F and 186FA, carry the size-designation codes common across China's small-engine industry, in which the digit sequence denotes cylinder bore and build size. This page gathers the models outside the named ranges.

The register lists here 3 versions with 4 to 6 kW rated output, all at 3,600 rpm, all single-cylinder with 78 to 86 mm bore and 62 to 72 mm stroke. Maximum torque ranges from 10.6 to 16.15 Nm, model years from 2011 to 2012; all three versions run direct injection at the Tier 4 (Final or Phase-in) emission stage and the under 8 kW power category.
The three versions form a closely staggered power series for portable generator sets, water pumps and simple agricultural machinery; the small differences in bore and stroke between the models allow fine steps in rated output within the same base engine.
On a used purchase, the oil level counts, along with the cooling fins on the air-cooled design, the condition of the injector and the tightness of the cylinder head gasket; on the older model years from 2011, it is also worth checking the fuel lines and starter motor.
