What the Goodty Industry filings say about the engines
Every Goodty Industry filing on record is carburetted — 2 certificate rows, 2008, and not one fuel-injected engine among them.
The engine codes on Goodty Industry's test vehicles —2 distinct across the filings — are led by 157QMI and 172MM. The code is stamped on the crankcase and is a better search term than the badge.
All 2 filings are 50-state certifications, so every one of these machines was certified for sale in California.
Rated power across the range runs from 6.5 kW to 10.5 kW (about 9 to 14 hp).
The vehicle builder named on every row is Zhejiang Tianya Property 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.
