What the number itself says
Reading JHSNX.976A15 left to right: J is the model-year letter for 2018, 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, .976 is the displacement in litres, so 976cc and A15 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 HS1000UTV-3) carried engine code HS2V91MY-1. In the Chinese engine-model convention that reads as 2 cylinders, V configuration, with a nominal 91 mm bore, MY series.
The certificate describes a four-stroke, twin-cylinder engine with 4 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 48.9 kW (about 66 hp) at 7,500 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.
