Fire Combustion Control System Based on Lambda Probe
Bartoš, Lukáš ; Tříska, Vít (referee) ; Šimek, Václav (advisor)
The bachelors thesis deals with a design of automatic regulation of biomass combustion in fireplaces by lambda probe. The probe measures residual amount of oxygen during the combustion and the measured value influences the efficiency of combustion process and harmful emissions which are emitted into the air. The first part of the thesis is focused onto a theoretical analysis of the proces of combustion and the effects which influence efficiency and emissions. The second part concerns the description and the use of necessary components for automatical combustion regulation. The third part deals with a pratical test which confirms or declines the possibility of regulation by measurement of residual amount of oxygen. The fourth part follows up with a design of a regulation algorithm and its implementation. The fifth part evaluates past tests and suggests a procedure for production.

Engine Motormanagement Software
Kopecký, Ivo ; Vítek, Ondřej (referee) ; Hájek, Vítězslav (advisor)
Fuel injection is a means of metering fuel into an internal combustion engine. In modern automotive applications, fuel metering is one of several functions performed by an "engine management system". A fuel injection system is designed and calibrated specifically for the type(s) of fuel it will handle: gasoline (petrol), Autogas LPG (also known as propane), ethanol, methanol, methane (natural gas), hydrogen or diesel. The majority of fuel injection systems are for gasoline or diesel applications. With the advent of electronic fuel injection, the diesel and gasoline hardware has become quite similar. During the last twenty years a preparation of a fuel mixture and the way of ignition in engine segment have changed the most. Instead of a carburettor it is being used the unit, which prepare fuel mixture according to a status of a car on the road e.g. change of pressure, temperature or ratio of a fuel and air.

Extension of biomass boiler
Kastner, Jakub ; Šťastný, Ladislav (referee) ; Burian, František (advisor)
Goal of this work is design and create extension data acquisition unit for existing system of heating boiler. Work is divided to theoretical and practical part. In theoretical part is mentioned methods of measuring temperature. Methods of measuring flue gas and placement of boilers into different classes according to standard ČSN EN 303-5:2013. The practical part deals with the design of schematic circuit for measuring the required parameters (lambda probe, thermocouple, measuring the light intensity using the photo-resist). Mechanical cover, testing created board under real conditions and the involvement of extension board into existing system of boiler. When commissioning the first version of the board appeared errors that were removed in the second version. In attempts to improve the operations of two boilers were found errors leading to the impossibility of any improvements.

Návrh šroubového spoje lambda sondy do vysokoteplotní aplikace
VALENTA, Marek
This bachelor's thesis deals with the design of a lambda probe screw connection to fulfil emission standards. The work describes the function of a lambda probe in the automotive industry, including description of their most frequently used types. The work includes description of measuring methods of leaks. The practical output of the work proposes the screw design to eliminate emission leak breaking the standarts.
