What the Yujiang Vehicle Technology filings say about the engines
Yujiang Vehicle Technology has filed only fuel-injected engines: 2 certificate rows and no carburettors at all, so a jet kit is the wrong search for any of them.
The engine codes on Yujiang Vehicle Technology's test vehicles —just one across the filings — are led by 2V91MW. The code is stamped on the crankcase and is a better search term than the badge.
None of the 2 filings is a 50-state certification: these were sold as 49-state machines, not certified for California.
Rated power on the record is 44 kW (about 59 hp).
The vehicle builder named on every row is Kunshan Yujiang Vehicle Technology Co., LTD.
Each figure is read straight off the EPA certificate rows; the per-family pages below carry the full breakdown for every engine family.
