Injection moulding
Heralt, Aleš ; Balej, Zdeněk (referee) ; Žák, Ladislav (advisor)
This Bachelor´s thesis is focused on construction forms for injection of thermoplastic matters. The technology for plastic products production is technology that participate more and more in production of all sorts of products - from technical components over kitchenware after as much as toys. Main part of this thesis is focused on description of the injection valve, ejector, annealing and ventilation system forms for injection with the main structural principles.

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.

Development and perspectives of common rail system
Gach, Jakub ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
This bachelor thesis is focused on the Common Rail injection system. It describes the origins of the system, its principle and the function of the individual parts of the system. It also deals with the development of individual system generations and their use. It is clear from the thesis that it is one of the best present-day injection systems that meets all the today's requirements for the design and construction of a vehicle.

Common Rail System for 6-cylinder Tractor Engine
Černoch, Josef ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
This thesis deals with the installation of modern high pressure injection common rail system to six-cylinder tractor engine. This system replaces injection system with in-line fuel injection pump. Common Rail system installation on an existing engine is designed with minimal design changes to the engine block and engine head. It is advantageous to minimize production costs of the transition to high-pressure injection system. The thesis contains the design and stress analysis of the new component for high-pressure injection system.

The High Pressure Fuel System for CI-engine
Strouhal, Pavel ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
This diploma thesis is focused on examining the development of a diesel tractor engine with a newer injection system, concretely common-rail system. Mainly it is about the application of the high pressure fuel pump, fuel rail and injectors. With regard to the used components are appropriate adjustments made on the engine, and then checked using the available calculations. Brief mention is given to the theoretical summary of the contemporary state of applied injection system and its development trend. Selecting adjustments is primarily based on observed operating load. However, it is also striving to their simplest implementation. An integral part of this work is drawing documentation of newly designed components.
