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).

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.

Modifying the Babetta engine
Poulíček, Matěj ; Píštěk, Václav (referee) ; Kaplan, Zdeněk (advisor)
This bachelor thesis is about one of the possible modifications of two-stroke single-cylinder Babetta 210 engine for increasing of power. Further about another manufactured Babetta engines with focus on their pros and cons. Attention is paid also to possible design changes for elimination of drawbacks.

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.
