What the number itself says

Reading JJILC.150QMJ left to right: J is the model-year letter for 2018, JIL is the three-character code the EPA assigned to Jili Scooter Import & Export as certificate holder, C marks a highway (street-legal) certification, .150 is the displacement in litres, so 150cc and QMJ is Jili Scooter Import & Export'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 Jili Scooter Import & Export submitted for this family (model JL150T-3A) carried engine code 1P57QMJ. In the Chinese engine-model convention that reads as one cylinder, horizontal (flat) cylinder, with a nominal 57 mm bore, QMJ series. Against the certified 149.6cc that implies a stroke of roughly 59 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 5.9 kW (about 8 hp) at 7,000 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.
