What this record says

Sold in the US by: Peace Industry Group (Usa), Inc.
Engine built by: Chongqing Astronautic Bashan
Vehicle category: Highway Motorcycle - Ib (50-169cc)
Certificate numbers: DPCGC.150S4A-002

What the number itself says

Reading DPCGC.150S4A left to right: D is the model-year letter for 2013, PCG is the three-character code the EPA assigned to Peace Industry Group (Usa) as certificate holder, C marks a highway (street-legal) certification, .150 is the displacement in litres, so 150cc 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 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

Peace Industry Group (Usa) filed one certificate under this family, for model year 2013, 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 7.5, HC 0.2 g/km.

What this configuration means when you shop for parts

Peace Industry Group (Usa) certified this 150cc engine 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 record gives no carburettor part number — measure the intake bore and the mounting on this 150cc engine before ordering.

The CVT behind this 150cc engine 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 TPGS-930 rather than ordering by displacement.

The PAIR valve Peace Industry Group (Usa) lists on this 150cc engine is an emissions part; its hoses perish and are the usual cause of popping on the overrun.

The exhaust on Peace Industry Group (Usa)'s DPCGC.150S4A carries a catalyst, so a replacement silencer without one changes what this 150cc engine was certified with.

Models certified under DPCGC.150S4A

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.
