Rotary Piston Engine for Small Mobile Systems
Drbal, Milan ; Puškár, Michal (referee) ; Žák,, Marek (referee) ; Píštěk, Václav (advisor)
The dissertation deals with the issue of 1D modelling of a rotary piston engine and prediction of engine characteristics for use in its further development. In this work, the 1D mathematical model of the engine is validated by measuring the combustion pressure in the work chamber, in the intake section and further in the exhaust channel. These data are used to determine the coefficients of the combustion model and, above all, the combustion chamber leakage model. Both effects cannot be modelled accurately included without measuring the work chamber pressures. The use of 1D mathematical simulations is well described in the literature for a reciprocating engine. However, their use for a rotary piston engine is more complicated from the point of view of the geometric differences of both types of engines. In this work, a suitable method of modelling rotary piston engines and their verification using technical experiments and CFD simulations will be described.

Advanced Control Algorithms of Powertrain Units
Špičák, Milan ; Puškár, Michal (referee) ; Slimařík,, Dušan (referee) ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
This thesis describes computational control of vehicle powertrains using common variable, engine torque. The thesis is divided into three main parts. The first one shows design of methods for torque estimation using known or measured variables on the vehicle. The second part contains design of powertrain control algorithm utilizing the engine torque as a common variable among individual modules. The third part describes experimental optimization of the longitudinal acceleration of a vehicle using torque control.
