What the number itself says

Reading GHALC.049HDZ left to right: G is the model-year letter for 2016, HAL is the three-character code the EPA assigned to Pacific Rim International West as certificate holder, C marks a highway (street-legal) certification, .049 is the displacement in litres, so 49cc and HDZ is Pacific Rim International West'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 Pacific Rim International West submitted for this family (model ZH-50ZC) carried engine code 1P39QMB/139QMB.

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 kW (about 3 hp) at 7,500 rpm, driving through a CVT (belt and variator).

Filing history and where it was sold

Pacific Rim International West filed one certificate under this family, for model year 2016, sold as 50-state, California included.

The vehicle itself is recorded as built by Huzhou Daixi Zhenhua Technology Trade Co. Ltd in China, while the engine came from Taizhou Xinba Motivity Manufacture Co., Ltd. Chassis parts and engine parts therefore have different origins.

Certified emission levels: CO 2.0, HC 0.4 g/km.

Other records carrying the same engine code

Pacific Rim International West certified an engine with this code under 8 other family numbers — the same engine filed again in another year, or in an off-road and a street version:

• FHALC.049HDZ (2015)
• HHALC.049HDZ (2017)
• JHALC.050ICB (2018)
• KHALC.050ICB (2019)
• LHALC.050ICB (2020)
• MHALC.050ICB (2021)
• NHALC.050ICB (2022)
• PHALC.050ICB (2023)

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.
