Power valve for Two Stroke Engine
Hanuš, Michal ; Tobiáš, Martin (referee) ; Janoušek, Michal (advisor)
Masters thesis focused on possible design aspects for electronically controlled two-stroke exhaust valve.
Fluid flow analysis in vicinity of exhaust valve using CFD
Šesták, Josef ; Náhlík, Luboš (referee) ; Vrbka, Martin (advisor)
This diploma thesis discuss a flow in a vicinity of exhaust valve using computational of fluid dynamics. In a light of current state of the problem solution this approach is forward but very sophisticated. Intention of author is description of multidimensional boundary of characteristic variables which determinates the flow behaviour for given geometry and boundary conditions. Technical knowlegde of fluid flow in vicinity of exhaust valve allow to design geometry which provide more effective cylinder flush out berofe the exhaust stroke will become. This process reduce quantity of loss work of piston and improve its effective pointers.
