What this record says

Sold in the US by: Pacific Rim International West, Inc.
Engine built by: Taizhou Xinba Motivity Manufacturer Co. Ltd
Vehicle category: Highway Motorcycle - Ib (50-169cc)
Certificate numbers: EHALC.150Z3L-005

What the number itself says

Reading EHALC.150Z3L left to right: E is the model-year letter for 2014, HAL is the three-character code the EPA assigned to Pacific Rim International West as certificate holder, C marks a highway (street-legal) certification, .150 is the displacement in litres, so 150cc and Z3L 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 Zhenhua ZH-Z3L) 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 150cc 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, 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 6 kW (about 8 hp) at 7,000 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 2014, sold as 49-state (not certified for sale in California).

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

Certified emission levels: CO 5.6, HC 0.3 g/km.

What this configuration means when you shop for parts

Pacific Rim International West certified the 1P57QMJ with a carburettor at 150cc, so the fuel-side wear items are the carburettor, its jets and float needle, the intake boot and the choke. The 57 mm bore in the code gives the engine size, not the carburettor size — measure the intake bore and the mounting on the 1P57QMJ before ordering.

The CVT behind the 1P57QMJ makes its drive belt, variator rollers and clutch shoes the consumables; belt length and width vary between 150cc machines, so measure the old belt on the Zhenhua ZH-Z3L rather than ordering by displacement.

The PAIR valve Pacific Rim International West lists on the 1P57QMJ is an emissions part; its hoses perish and are the usual cause of popping on the overrun.

The exhaust on Pacific Rim International West's EHALC.150Z3L carries a catalyst, so a replacement silencer without one changes what the 1P57QMJ was certified with.

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.
