Engine Motormanagement Software
Huška, Lukáš ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
This master thesis deals with ignition systems which are used in cars vehicles with gas engines and also with setting of the best moment of ignition of gasoline-air mixture in cylinders of engine. Ways of gas injection at diesel engines and their control systems are also described in this thesis. Next chapter deals with control unit and describes main actions which are necessary for today’s motor vehicles. As illustration is used example of succession of actions which are necessary for calculation and setting regular value of pre-ignition. At the end is shown animation, which can be used for practice lessons in a subject Automobile Electric and Electronic Systems as a example. It will simplify understanding of described activities which are all accomplished by central control unit. For purposes of laboratory lessons is in this thesis also discussed measuring of engine performance with changes of parameter of central control unit.

Production technology for an ignition stator body of the Jawa Pionýr motorcycle
Zeman, Petr ; Dvořák, Jaromír (referee) ; Sliwková, Petra (advisor)
The Jawa 50 motorcycles, produced in several models between 1958 and 1982, were equipped with several types of ignitions. From the current point of view, they are not satisfactory. The bachelor´s thesis describes the original designs, the commercial and amateur modifications of the ignition and its advantages and disadvantages, and deals with the innovative design and variants of mounting by individual coils. The work further deals with production of the ignition body by choosing a semi-finished product, machines and tools and compilation of a technological procedure and drawing documentation.

Sensors and Actuators for Combustion Engines
Prouza, Jiří ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
This bachelor thesis is concerned with a summary of the most important sensors and control members which are used for combustion engine. There is a description of the construction and the principle of function of each sensor and member in this thesis. The first part of this thesis is concerned with sensors, which scan a condition and a course of activities in an engine, transform them to a signal and afterwards send them to the control unit, so it could process them. In the second part of this thesis there is a description of control members which process information from the control unit and afterwards transform them to a mechanical movement.

Capacitive Ignition System
Benček, Kristián ; Bazala, Jiří (referee) ; Beran, Martin (advisor)
Bachelor thesis deals with the complex issue of ignition system, with a special emphasis put on the capacitive ignition. Due to the later needs the knowledge of the principles, on the basis of which the individual internal combustion piston engines work is the beginning of a work dedicated to the just distribution of these engines according to the basic criteria and elementary define different types of piston internal combustion engines and storylines, which in them take place. Subsequently is described in detail dismantled the issue of the kindle system as a whole but also the individual components of the ignition system and attention is required even to properly set the most suitable moment of ignition (pre-ignition) and the need to ensure sufficient ignition energy. Ignition systems are divided according to the historical development from the earliest induction of the classical ignition until after the state of the art fully electronic ignition system. The greatest emphasis is put on detailed analysis of the capacitive ignition, which is then compared with the conventional ignition. The last part is devoted to the management of the combustion event using the initialization of the burning. As an example, that the management of the combustion event using the initialization of the burning is nowadays a real, is referred to the engine Skyactive X, which should be in 2019, the commonly commercially used in the model of the Mazda 3.

Electronic Ignition Unit for Combustion Engine
Čmelík, Matouš ; Knobloch, Jan (referee) ; Červinka, Dalibor (advisor)
Thesis deals with electronic ignition for a two-cylinder two-stroke engines. In the thesis is described the existing ignition system. In the thesis are described measurement options of the position ot the engine crankshaft. The ignition system is designed mainly for motor JAWA, CZ and motor Trabant. The design is focused on reliability of entire circuit. The main advantage of the entire proposed design is possibility to adjustable ignition curve, depending on several external parameters such as speed or temperature of the engine. The proposed ignition has been tested in vehicle Velorex.

Fuel Injection Analysis
Schnabl, Jan ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
The ignition and injection system in any form are an integral part of each car. The development of these systems goes hand in hand with the development of the automobile and his growing industry. Since the nineteenth century to the present occurred in this sector signifcant progress. This thesis is focused primarily on the description of the two systems and their partiton. The development has been recorded from the oldest systems to the newest systems.

Programmable ignition system for spark-ignition engine
Friedel, Daniel ; Kubíček, Michal (referee) ; Tošovský, Petr (advisor)
This thesis is concerned with design of programmable capacitive ignition, powered from board grid. Universality of the system, especially possibility to change values of timing of early spark via changes of programme in microcontroller was taken as major goal. Microcontroller is used as the operative element of ignition. Commonly used methods for sensing of engine speed and managing of ignition are defined and explained at the begining of the thesis. Also is presented realisation of hardware and software part and draw up the methodology calibration of the speed sensor. The ignition is designed to avoid the need to intervene in the high voltage ignition system.

Combustion Engine Ignition and Fuel Injection Control (Motormanagement)
Škrabal, Martin ; Mikulčík, Aleš (referee) ; Hájek, Vítězslav (advisor)
Undoubtedly the most important and absolutely essential electrical systems located in vehicles which are powered by internal combustion spark-ignition engine is the ignition system of the engine. Without this the engine, or the whole vehicle can not operate properly. Since the beginning of spark ignition engines ignition system executing a complex and long term development effort driven by the best function of the engine. Unlike the ignition, which had to work from the outset the development of spark ignition engines has been to introduce more to the use of injection in the 70 the 20th century. From simple control systems, ignition and injection on the mechanical principle of working out the development of electronic management units. In most modern combustion engines is the management of the ignition and injection is carried out using a common system with one central control unit. Most of this type of system-Motronic system from Bosch-used today in different variations large number of producers cars. In history was the main objective of the management system to achieve the highest possible power, now coming oil crisis be brought to the forefront of the fuel consumption and the implementation of emission standards (in the Czech Republic EURO standards).

Engine Motormanagement Software
Kuda, Roman ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Increasing requirements and claims on running of motor vehicles contributed to development of new systems on the mixture preparations of fuel and ignition. Cardinal causes, which led to the very intensive research and later introduction of superior systems of injection and ignition, where fulfilment of stricter emission limits, lower fuel consumption at prezent engine-power increase and engine torque. The conception of the classical gas-engine was not changed over the past few years. The supervising elements as ignition and injestions of engines are continuously changed.
