Which Hua Rong International Corp. models have a Chinese-built engine?

2 of the 56 US certificate filings on record for Hua Rong International Corp. name an engine manufacturer in China, across 2007–2015: Chongqing Loncin, Longxin. The rest of the range is built elsewhere and is not covered by this registry.

Will parts from another brand fit my Hua Rong International Corp.?

A shared factory and engine size makes another brand a strong candidate, but it does not prove the part numbers match. These machines are assembled from multiple component suppliers, so measure the part you have before ordering a replacement.

What the Hua Rong International filings say about the engines

Every Hua Rong International filing on record is carburetted — 2 certificate rows, 2007 to 2015, and not one fuel-injected engine among them.

The engine codes on Hua Rong International's test vehicles —just one across the filings — are led by FY139FMB. The code is stamped on the crankcase and is a better search term than the badge.

1 of the 2 filings are 50-state (California-legal); the other 1 were 49-state only.

Rated power across the range runs from 2 kW to 4.3 kW (about 3 to 6 hp).

The vehicle builders named are Guangzhou Panyu Huanan Motors Group Co., Ltd. and ZHEJIANG SHENGQI MOTION APPARATUS CO. LTD. — the chassis and the engine do not always share a source.

Each figure is read straight off the EPA certificate rows; the per-family pages below carry the full breakdown for every engine family.
