PROGRAMABILNI RAČUNALNIK ZA 4-TAKTNE MOTORJE Z VBRIZGOM GORIVA
Damir Horvat, 2011, diplomsko delo

Opis: V diplomski nalogi smo predstavili pregled elektronskega vbrizga goriva in vžiga pri 4-taktnem bencinskem motorju. Predstavljeni bodo osnovni principi, uporaba in delovanje senzorjev in aktuatorjev pri elektronskem vbrizgu goriva. V nadaljevanju smo se osredotočili na prostoprogramabilne motorne računalnike. Največji poudarek diplomskega dela je na programiranju nadzorne enote, izbiri primernih senzorjev in aktuatorjev, ter na meritvah in rezultatih.
Ključne besede: 4-taktni motor, senzorji, aktuatorji, elektronski vbrizg goriva, elektronski vžig, programabilni računalnik, mikrokrmilnik

Simulation of automotive air-conditioning system in 1D simulation software
Marko Copot, 2019, diplomsko delo

Opis: The development of state-of-the-art vehicles requires advanced simulations tools in heating, ventilation and air-conditioning (HVAC). The focus of this thesis is the construction of an automotive HVAC model, its calibration and the simulation of the behaviour of the HVAC model in various ambient conditions. The theoretical background of refrigeration system as part of the HVAC system is presented. The model is constructed with following components: compressor, condenser, throttling device, evaporator and battery chiller, which is a heat exchanger between coolant and refrigerant. The description and role of each component in the HVAC model is presented. All heat exchangers are calibrated, which is done with multiple simulations that have defined input data. The results are compared to experimental data. With addition of vehicle cabin with air recirculation, HVAC control logic is implemented. The behaviour of the system is simulated in defined environmental conditions. The results of the simulations are presented in graphs and tables.
