It reminds me of the notorious Fish carburetor.
Fish Carburetors – Ross Carburetors
Similar performance claimed, and altitude compensation. Six to ten discharge point is one difference.
They call it smart but it isn't an Internet of Things play. |
All my motorcycles had cable-controlled or vacuum diaphragm-controlled slide-valve/ metering rod carbs.
Aerodynamically, I don't think that they're any improvement.
The hydro-electric dam bullet-valve and Junkers JUMO 004 jet turbine bullet- valves are probably the zenith of low-drag valve technology. I chose a facsimile for Spirit's cooling system.
The FISH carburetor lived up to some of the claims.
Push the vehicle up to 35-mph, bump-start the engine, and drive at 35-mph. There was no provision for acceleration or deceleration, just 35-mph.
