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

3 of the 8 US certificate filings on record for Cmsi Inc. name an engine manufacturer in China, across 2008–2010: Benzhou Vehicle Industry Group Co.,Ltd., Taizhou Zhongneng (ZNEN). The rest of the range is built elsewhere and is not covered by this registry.

Will parts from another brand fit my Cmsi 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 Cmsi filings say about the engines

Every Cmsi filing on record is carburetted — 3 certificate rows, 2008 to 2010, and not one fuel-injected engine among them.

The engine codes on Cmsi's test vehicles —3 distinct across the filings — are led by BZ157QMJ, BN157QMJ and 150CMS. The code is stamped on the crankcase and is a better search term than the badge.

All 3 filings are 50-state certifications, so every one of these machines was certified for sale in California.

Rated power across the range runs from 2.2 kW to 7 kW (about 3 to 9 hp).

The vehicle builders named are Benzhou Vehicle Industry Group Co.,Ltd., Taizhou Zhongneng Motorcycle Co.,Ltd. and Zhongneng Industry Group — 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.

The factory changed. Here is when.
