Fully variable valve control: a geometric approach. (English) Zbl 1432.53013

The paper suggests a geometric solution to the problem of variable valve control that is important for both energy efficiency and emission reduction of combustion engines. The authors’ approach resorts on a particular engineering idea for the cam design allowing certain flexibility and a rigorous mathematical investigation from both geometric and mechanical perspective. For readers with background in any of those fields, the style of the exposition is quite comprehensive and yet precise. In addition to the explicit calculations and a rigorous proof of their main results, the authors provide also detailed pictures, specific examples and discussion of possible applications.
