LD186FA by Fuzhou Leading Power: small diesel engine rated at 6 kW for mobile pumps, built in 2012, from the widely used engine family in China carrying the 186F designation
Fuzhou Leading Power is, as its name shows, a Chinese manufacturer of small diesel engines based in the city of Fuzhou. Engines like this are built in parallel by numerous manufacturers across China and sold under different trade names, even though the underlying design is widely shared.

Built in 2012, the LD186FA is rated at 6 kW. Small diesel engines in this power class are typically compact single-cylinder designs with direct injection and air cooling in the nonroad segment, built for low weight and simple maintenance rather than high engine speed.
Engines rated at 6 kW in this equipment class often drive mobile pumps, for instance to irrigate farmland or to pump water off construction sites, where a light, portable drive matters more than a high flow rate from a single pump. Beyond its narrow production-year window, the basic engine design in this power segment stayed stable.
When buying a used LD186FA fitted in a pump unit, besides checking the engine for compression and oil leaks at the seals, inspect the pump coupling for leaks, since water can easily work its way toward the engine at this point. The cooling fins of the air-cooled single-cylinder unit should be checked for dirt, and since injection pumps from different Chinese manufacturers, despite a similar design, often do not fit one another, spare-parts availability should be clarified before buying.
