Vegetable oil as a fuel for a diesel engine
Kuběna, Pavel ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This thesis offers an opportunity to get closely acquainted with ignition engines running on alternative fuels. At the beginning of this work the reader is offered a wide variety of alternative fuels since born automotive industry, their basic information, features, use, and technical issues of each fuel. In the following part of this thesis, the author deals only with vegetable oil and its potential use as a fuel in an ignition internal combustion engine. It focuses on the specific conversion vehicles, their complexity, advantages and disadvantages, the overall economy of operation and risks of using vegetable oil instead of conventional diesel fuel. There is also documented performance characteristics and ecological balance of a particular target vehicle.

Modification of a four cylinder diesel engine to a single cylinder test engine
Mátyás, Attila ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This thesis deals with modification of an existing four-cylinder diesel engine to a singlecylinder research engine. The work is divided into four main parts. The first part is theoretical, briefly describes research engines, their individual types and provides an overview of their functions. The second part of the work includes the modification of a four-cylinder diesel engine to a single-cylinder research engine, focusing mainly on balancing inertia forces. The third, most extensive chapter contains the structural analysis of the crankshaft. The last part contains the design of a torsional coupling, which ensures the connection of the engine with the dynamometer.
