What the number itself says

Reading LHSNX.196MB9 left to right: L is the model-year letter for 2020, 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.

Filing history and where it was sold

Hisun Motors Corp., U.S.A. filed one certificate under this family, for model year 2020, sold as 49-state (not certified for sale in California).

The vehicle itself is recorded as built by Chongqing Huansong Science and Technology Industrial Co., Ltd. and Vietnam New Century Industrial Company Limited in China and Vietnam, while the engine came from Chongqing Huansong. Chassis parts and engine parts therefore have different origins.

Certified emission levels: CO 11.3, HC+NOx 0.5 g/km.

Hisun Motors Corp., U.S.A. certified an engine with this code under 13 other family numbers — the same engine filed again in another year, or in an off-road and a street version:

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.
