What the number itself says

Reading SJYMC.049DP2 left to right: S is the model-year letter for 2025, JYM is the three-character code the EPA assigned to Jymoto Enterprises as certificate holder, C marks a highway (street-legal) certification, .049 is the displacement in litres, so 49cc and DP2 is Jymoto Enterprises' 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 Jymoto Enterprises submitted for this family (model FALCON-50) carried engine code 1P39QMA. In the Chinese engine-model convention that reads as one cylinder, horizontal (flat) cylinder, with a nominal 39 mm bore, QMA series. Against the certified 49cc that implies a stroke of roughly 41 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 2.4 kW (about 3 hp) at 7,500 rpm, driving through a CVT (belt and variator).

Filing history and where it was sold

Jymoto Enterprises filed one certificate under this family, for model year 2025, sold as 49-state (not certified for sale in California).

The vehicle itself is recorded as built by the same company, ZHEJIANG JIANYING LOCOMOTIVE CO., LTD. in CHINA — engine and chassis from one source.

Certified emission levels: CO 6.3, HC 0.5 g/km.

Other records carrying the same engine code

Jymoto Enterprises 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:

• TJYMC.049DP2 (2026)

Other certificate holders whose test vehicle carried the same engine code (10 of 12 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.
