Observing the drawings shown in the patent application, it can be seen that the supercharging system is actuated by a centrifugal compressor, similar to that of the Kawasaki Ninja and Z H2, mounted on one of the two cylinder heads and controlled by the camshaft. The air that this sucks comes channeled and pushed through an intercooler and from there into a single throttle body, to then be routed through a Y-duct into the intake system of both cylinder heads.
This patent illustrates a more compact system compared to a traditional one, in which the activation of the compressor should take place thanks to the crankshaft, but in doing so it must be taken into account that the camshaft runs at a slow speed compared to the engine one (about half) and therefore a higher capacity compressor is needed to obtain the same result.
To overcome this problem, the Benda engineers have developed a solution whereby the compressor is controlled via a variable ratio transmission with belt trapezoidal and movable pulleys, reminiscent in some ways of the automatic transmission of a scooter. This would allow the response of the compressor to be adjusted according to the rotation speed.
