What the Dareopen International filings say about the engines
Dareopen International's filings mix carburettors and fuel injection: 1 row carburetted, 1 injected. The first injected family appears in 2020; in 2020 the split was 1 carburetted to 1 injected. Check which you have before buying anything on the fuel side.
The engine codes on Dareopen International's test vehicles —2 distinct across the filings — are led by 253FMM and 1P39QMA. 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 across the range runs from 2.1 kW to 12.5 kW (about 3 to 17 hp).
The vehicle builders named are Ningbo Dalong smooth Locomotive Industry Co., Ltd. and Ningbo Dalong Smooth Locomotive 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.
