What the number itself says

Reading PTMMX.120ATA left to right: P is the model-year letter for 2023, TMM is the three-character code the EPA assigned to Tao Motor as certificate holder, X marks an off-road certification, .120 is the displacement in litres, so 120cc and ATA is Tao 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 Tao Motor submitted for this family (model ATK125A1) carried engine code 154FMI. In the Chinese engine-model convention that reads as one cylinder with a nominal 54 mm bore, FMI series.

The certificate describes a four-stroke, single-cylinder engine with 2 valves per cylinder fed by carburettor. No catalytic converter is listed.

Rated power on the record is 5.8 kW (about 8 hp) at 7,500 rpm, driving through a 3-speed manual gearbox.

Other certificate holders whose test vehicle carried the same engine code (10 of 127 shown):

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.
