Cylinder deactivation of a spark-ignition engine
Fridrichová, Kateřina ; Píštěk, Václav (referee) ; Drápal, Lubomír (advisor)
This thesis focuses on a technology called cylinder deactivation. The technology helps reducing emissions and fuel consumption. The first part summarizes the possibilities of application of the cylinder deactivation technology as well as advantages resulting from combination with other technologies. The thesis also consists of two design options for valvetrain in inline four-cylinder engine and the results of simulations of dynamics of its cranktrain.

Cylinder Deactivation for Internal-combustion Engines
Fridrichová, Kateřina ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
This bachelor’s thesis focuses on a technology reducing fuel consumption and emissions called cylinder deactivation. The evolution of the technology is described in the first part of the thesis together with explanation of the nature of fuel savings. The description of consequences associated with usage of the technology and possible design approaches for gasoline engines are written in the following part. The thesis also incorporates the results of test performed on diesel engines, where the technology is not currently in production. The last part includes other components used in engines with cylinder deactivation, especially vibration absorbers, together with some examples of application of this technology.
