What the number itself says

Reading KHSNX.735UTV 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, .735 is the displacement in litres, so 735cc and UTV 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 HS750UTV-6) carried engine code HS1102MV. In the Chinese engine-model convention that reads as one cylinder with a nominal 102 mm bore, MV series.

The certificate describes a four-stroke, single-cylinder engine with 5 valves per cylinder fed by sequential multi-port fuel injection, with an oxygen sensor for closed-loop fuelling, run by an engine control module (ECM). There is a catalytic converter in the exhaust, recorded as "Three Way Catalyst (TWC), single-bed, closed-loop warm up".

Rated power on the record is 28.8 kW (about 39 hp) at 6,000 rpm, driving through a CVT (belt and variator).

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.
