Triangle valve - Idea

An idea came to my mind and it is the design of triangle-shaped valves with rounded corners. This type of valve, if used on the cylinder head with the air inlet in the form of a rotating triangle, can greatly disturb the flow of the fuel and air mixture and achieve a very good mixing. Of course, this is not the only issue, and the discussion of durability and construction method has not yet been investigated and is only an idea.
