What the number itself says

Reading KHSNX.196MB9 left to right: K is the model-year letter for 2019, HSN is the three-character code the EPA assigned to Hisun Motors Corp., U.S.A. as certificate holder, X marks an off-road certification, .196 is the displacement in litres, so 196cc and MB9 is Hisun Motors Corp., U.S.A.'s own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.

The engine, as described on the certificate

The test vehicle Hisun Motors Corp., U.S.A. submitted for this family (model HS200) carried engine code HS168FML. In the Chinese engine-model convention that reads as one cylinder with a nominal 68 mm bore, FML series. Against the certified 196cc that implies a stroke of roughly 54 mm — a sanity check for a piston or cylinder listing, not a published figure.

The certificate describes a four-stroke, single-cylinder engine with 2 valves per cylinder fed by carburettor, run by an ignition control module (CDI-type ignition). There is a catalytic converter in the exhaust, recorded as "TWC, single bed, open loop". The head carries a pulse secondary-air (PAIR) valve.

Rated power on the record is 3.8 kW (about 5 hp) at 3,600 rpm, driving through an automatic.

A shared code from the same factory is a strong search lead. From a different factory it is as often a naming coincidence. Either way it narrows the search; it does not settle it — measure before you buy.
