New Vertical four-cylinder engine model (H75)
This is a vertical duplex gasoline engine engine, which is made of brass and stainless steel. It uses water circulation cooling with a heat dissipation tank, a water pump and a fan.
The ignition system uses our newly developed electronic components. This engine model has a bore of 13MM, a stroke of 20MM, a displacement of5MM, and a total weight of 3450G. Power supply with 4.5V.
We design the engine with a mechanical limiter. It allows the engine to stabilize a set of speed. This is a perfect mechanical craft. When it is added, it can work normally.
You will fans for it!
