The thesis deals with the design of a small-volume four-stroke internal combustion engine with a maximum displacement of 10 cc and a power of 1 kW for autonomous devices of smaller dimensions. In addition to the analysis of individual propulsions for small aircraft, there is also a chapter with the comparison of an internal combustion engine and an electric motor with similar power. Another part of the work is the creation of a thermodynamic model in the GT Power program and its subsequent optimization to increase the overall efficiency of the engine.

The master’s thesis is focused on creating a thermodynamic model of the diesel engine for heavy commercial vehicle. After the model was created, new intake and exhaust pipes are designed based on simulations. Those proposed pipes variants are compared with the series design. After evaluating individual variants, the final version of the new pipes is selected and 3D model for this version is created.

The master´s thesis is focused on the design of the intake and exhaust ducts for V8 engine. Home work is focused on the description of the construction of the intake and exhaust pipes for a given engine. Another part deals with creating a thermodynamic model of the engine, and the design of the intake and exhaust pipes. The last part deals with verifying the proposed pipeline construction.

This master thesis summarizes the basic knowledge in the field of turbocharging of internal combustion piston engines. It also focuses on the analysis of some properties of multistage turbocharging, especially for diesel engines. Using analytical relationships, a model in the form of a web application has been created, which describes the cooperation of a turbocharger or turbochargers with an internal combustion engine. With the help of this model, some two-stage supercharging options for the selected engine have been then proposed.

This diploma thesis is focused on construction of one-cylinder four stroke engine designed for motocross competition. The target was create the 3D model, which has foundation on the thermodynamic simulation. Kinematics of timing mechanism was designed in Lotus Simulation. For checking the main bearings life calculation was performed.

This work describes exceptional properties of McKibben pneumatical muscle and introduces its state-of-the-art model. The mathematical model is extended especially in a field of a thermodymical behavior. A new model applies a method used for describing of a thermodynamical behavior of pneumatic cylinders until now. This method is significantly upgraded to fit a muscle behavior, particularly by considering a heat generated by a muscle internal natural friction. The model is than verified and discussed with a real system. The haptic part introduces a development and design of a haptic glove interface for the use in robotics, especially in telepresence, or in VR. The force and touch feedback is provided by Pneumatic Muscles controlled by an open loop algorithm using the introduced mathematical model. The design is light and compact.
