Which Chironex Inc. models have a Chinese-built engine?

10 of the 11 US certificate filings on record for Chironex Inc. name an engine manufacturer in China, across 2010–2013: Chery Automobile Co., Ltd., Taizhou Zhongneng (ZNEN), Zhejiang Xinyang Industry Co.,Ltd.. The rest of the range is built elsewhere and is not covered by this registry.

Will parts from another brand fit my Chironex Inc.?

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 Chironex filings say about the engines

Chironex's filings mix carburettors and fuel injection: 8 rows carburetted, 2 injected. The first injected family appears in 2013; in 2013 the split was 2 carburetted to 2 injected. Check which you have before buying anything on the fuel side.

The engine codes on Chironex's test vehicles —4 distinct across the filings — are led by BN157QMJ, BN139QMB, BN172MM and FT1390MB. The code is stamped on the crankcase and is a better search term than the badge.

None of the 10 filings is a 50-state certification: these were sold as 49-state machines, not certified for California.

Rated power across the range runs from 2 kW to 50 kW (about 3 to 67 hp).

The vehicle builders named are Taizhou Zhongneng Motorcycle Co.,Ltd., Zhejiang Xinyang Industry Co.,Ltd. and ZHEJIANG XINYANG INDUSTRY 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.
