What the Hjs filings say about the engines
Every Hjs filing on record is carburetted — 2 certificate rows, 2015 to 2016, and not one fuel-injected engine among them.
The engine codes on Hjs' test vehicles —just one across the filings — are led by XY163QML. 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 6.5 kW (about 9 hp).
The vehicle builder named on every row is Taizhou Nebula Power 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.
