What the number itself says

Reading EPCGC.049S4A left to right: E is the model-year letter for 2014, PCG is the three-character code the EPA assigned to Peace Industry Group (Usa) as certificate holder, C marks a highway (street-legal) certification, .049 is the displacement in litres, so 49cc and S4A is Peace Industry Group (Usa)'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 Peace Industry Group (Usa) submitted for this family (model TPGS810) carried engine code 1P39QMB. In the Chinese engine-model convention that reads as one cylinder, horizontal (flat) cylinder, with a nominal 39 mm bore, QMB 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). No catalytic converter is listed. The head carries a pulse secondary-air (PAIR) valve.

Rated power on the record is 1.8 kW (about 2 hp) at 7,000 rpm, driving through a CVT (belt and variator).

Filing history and where it was sold

Peace Industry Group (Usa) filed one certificate under this family, for model year 2014, sold as 49-state (not certified for sale in California).

The vehicle itself is recorded as built by the same company, Chongqing Astronautic Bashan Motorcycle Manufacturing Co.,Ltd in China — engine and chassis from one source.

Certified emission levels: CO 8.7, HC 0.9 g/km.

Other records carrying the same engine code

Peace Industry Group (Usa) 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:

  • FPCGC.049S4A (2015)

Other certificate holders whose test vehicle carried the same engine code (10 of 60 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.

Models certified under EPCGC.049S4A

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.
