It would be a worldwide novelty: never before had a variable regulation system been seen in a scooter engine.
Piaggio has patented this, to be applied to its single-cylinder and single-shaft engines, and Vespa immediately comes to mind, which in terms of positioning and hierarchy seems to us the most suitable model for the debut of such a system.
The patent is completely different from the one dedicated to the Aprilia RSV4 V4 engine, which we saw a few months ago, and involves an actuator connected to a shaft with a differentiated profile.
The different profile of the shaft, depending on the positioning guaranteed by the actuator, allows for a different lift of the valves depending on the engine speed, resulting in improvements in torque delivery and maximum power acquisition.
We imagine that these could be increased by 25% without touching the displacement and, above all, ensuring compliance with current and future pollution standards.
We don’t know when we’ll see it, but it would be a great step forward in the world of scooters.
