Increasing Efficiency of Intake Port for SI Engine
Herka, Miroslav ; Drápal, Lubomír (referee) ; Svída, David (advisor)
The thesis describes design solutions the inlet port of the modern combustion engine. The thesis describes basic properties of the inlet port and the types of flow. It is focused the experimental measure of the real inlet port engine Husaberg. The results of the experimental measure are compared with results of the simulation in software CFD. Moreover, it describes creation of 3D parametric model in software Pro/Engineer based on the real geometry exquired from software ATOS. At the end of the work are compared with results of the simulation origin geometry inlet port with origin inlet valve with different changes shapes of valve.

Intake Manifold for Single-cylinder Engine
Pavličík, Lukáš ; Janoušek, Michal (referee) ; Svída, David (advisor)
The aim of this diploma thesis is to create a thermodynamic computational model of a single cylinder IC engine for the Formula SAE car. The single cylinder SI engine KTM 500 EXC is considered as a powertrain unit. The intake manifold of the serial enduro motorcycle is modified according to the Formula SAE 2014 rules. Analysis of the one dimensional flow is performed by using Lotus engine simulation software.

Vliv konstrukčních změn sacího a výfukového traktu na výkonové a emisní parametry motoru
Šenkyřík, Michal
This thesis deals with the design changes of intake and exhaust systems of naturally aspirated combustion engine with the aim to improve its dynamic characteristics. An overview of intake and exhaust tract designs (together with their impact on the engine efficiency) is provided in the introductory part of the thesis. Based on this knowledge, modifications of the intake and exhaust systems of Ford Windsor V8 engine were proposed and installed in a vehicle. A series of dynamic and static tests on chassis dynamometer were carried out in order to measure the impact of the changes on the torque curve. The impacts of the changes are presented in detailed analysis of power and torque characteristics with respect to the engine speed. The results are discussed and the possible causes of observed phenomena are identified.
