What the number itself says

Reading TWMIC.180TY1 left to right: T is the model-year letter for 2026, WMI is the three-character code the EPA assigned to Wansen Motor as certificate holder, C marks a highway (street-legal) certification, .180 is the displacement in litres, so 180cc and TY1 is Wansen Motor'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 Wansen Motor submitted for this family (model TY200T-A) carried engine code 1P63QMK. In the Chinese engine-model convention that reads as one cylinder, horizontal (flat) cylinder, with a nominal 63 mm bore, QMK series. Against the certified 180.4cc that implies a stroke of roughly 58 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 throttle-body fuel injection, with an oxygen sensor for closed-loop fuelling, run by an engine control module (ECM). No catalytic converter is listed.

Rated power on the record is 10 kW (about 13 hp) at 7,000 rpm, driving through a CVT (belt and variator).

Filing history and where it was sold

Wansen Motor filed one certificate under this family, for model year 2026, sold as 50-state, California included.

The vehicle itself is recorded as built by Zhejiang Tianying Locomotive Co., Ltd. in China, while the engine came from Taizhou Handa Engine Science Co., Ltd. Chassis parts and engine parts therefore have different origins.

Certified emission levels: CO 2.5, HC 0.3 g/km.

Other records carrying the same engine code

Wansen Motor certified an engine with this code under one other family number — 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.

Models certified under TWMIC.180TY1

Every model designation the importer listed on this certificate. If your machine's model name appears here, this is the right record — even if the name on the bodywork is slightly different.
