The engine, as described on the certificate

The test vehicle Taotao USA submitted for this family (model ATK125-A) carried engine code TZH157FMI. In the Chinese engine-model convention that reads as one cylinder with a nominal 57 mm bore, FMI series. Against the certified 107cc that implies a stroke of roughly 42 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. 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 4.5 kW (about 6 hp) at 8,000 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.
