The engine unit of a building machine
Nejman, Jan ; Pokorný, Prokop (referee) ; Kašpárek, Jaroslav (advisor)
This thesis is concerned about wheel building loaders and their engine unit. There is a brief description of machines fulfilling assignment parameters in the first part, including their construction, processing and steering solution. The following part consists of total power assessment. Total power is reached by addition of all needed power for various process modes. The last part deals with searching for suitable engine unit according to worldwide producer's catalogues.

The engine unit of a loader
Vaněk, David ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
This paper deals with a design of wheel loader’s engine unit and its performance, as well as the choice of suitable unit itself. Theoretical part describes a standard approach used in designing loaders in the performance and weight class according to the parameters listed and also introduces common designs of loader’s individual parts. It gives the reader an overview of various machines currently available on today’s market and their comparison. The second part of the thesis consists of performance design and calculations based on the comparison of performances needed for various working modes of the machine, where the performance are calculated as a sum of partial performances of differents parts of machines. The result of this paper is a choice of motorized unit that suits all the designed and calculated parameters.

Engine unit of the forestry forwarder
Koukal, Vojtěch ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor’s thesis deals with theme of forest forwarders. In the first chapter there is research analysis of forestry forwarders in similar weight category. In the second chapter there is a calculated performance of the engine according to entered parameters. Based on the computed values the best engine unit is selected from the catalogues of manufacturers.

The engine unit of a loader
Koksa, David ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
The work is focused on loading construction machinery and their engine units. The theoretical background research introduces the domain of wheeled loaders. Subsequently, three specific machines, which are available on the market, are selected from a similar model range. They are selected according to the specified technical criteria. Individual power requirements for various modes of operation are calculated according to a suitable algorithm. These power requirements are summed up to obtain the needed total power. Based on the calculated value of the total power the suitable engines from various producers are proposed at the end of this work. This was the goal of the work.
