Suction Piping with Variable Lenght
Vojkůvka, František ; Svída, David (referee) ; Dundálek, Radim (advisor)
The object of the bachelor thesis is to create a search concerning questions of the suction piping with variable length. Introduction of the project is devoted to the suction system of the spark ignition engines and the description of each parts. There is further explicated an influence of the suction piping with variable length on torque and performance behaviour and dynamic supercharging utilitazion. The enumaration of used structural design of the suction piping with variable length is presented as well. A great deal of the project is devoted to the specific engines, that use the suction piping with variable length.

Bidirectional pneumatic stepper motor
Veselý, Václav ; Pavlík, Jan (referee) ; Kolíbal, Zdeněk (advisor)
The diploma thesis Bidirectional pneumatic stepper motor concentrates on a step shaft rotation in the presented scheme of a kinematic mechanism. The introductory research part of the diploma thesis lists various types of pneumatic components and the analysis of elements in pneumatic circuits is provided. The following section of the thesis concentrates on designing a new scheme of a pneumatic stepper and construction of a functional mock-up. The final part of the diploma thesis offers a summary and final evaluation of the design and offers subsequent alterations for its further usage.

The design of fast electromagnetic valve for semiactive damper
Žižlavský, Vít ; Špalek, Petr (referee) ; Strecker, Zbyněk (advisor)
This diploma thesis’s focuses on the mechanical design of fast solenoid throttle valve for DCC semiactive damper. Current DCC dampers work with a time response of over 10 ms, which is not suitable for fast semiactive control of vehicle chassis. The time response needs to be shortened, to improve quality of regulation. The required time response is archived by new fast electromagnetic actuator for original CES valve. The actuator has been accelerated by reducing induction of eddy currents and by reducing weight of moving parts. New valve helped to reduce the time response of damper by 28 % to 8,1 ms. The results proved, that the time response is affected more by speed of the servo effect, which is closing main orifice, than by electromagnetic actuator. There is no more potential in accelerating CES valve by actuator.

Návrh automatizovaného systému pro zavlažování zahrady
Vaněk, Jakub
This work introduces the issue of automatic irrigation. It also provides a brief overview of currently offered commercial solutions and a description of their advantages and disadvantages. The main part of the thesis describes the design and procedure for the realization of the own irrigation system, a detailed introduction to the finished system, the course of its testing in laboratory conditions and, finally, its comparison with commercially available competition.
