Abstract
U ovom završnom radu analiziran je zadani atmosferski Otto motor s četiri cilindra u liniji i snagom od 110 kW pri 6000 min-1. Nakon izračunatih radnih parametara zadanog motora izvršeno je nekoliko njegovih nadogradnji. Najprije je motor nadograđen turbopuhalom, zatim hladnjakom zraka i na kraju waste-gate ventilom. Za svaku varijantu motora izračunati su radni parametri u rasponu brzina vrtnje od 1000 min-1 do 6000 min-1. Za sve varijante motora uspoređene su promjene tlaka i temperature u cilindru motora. Maksimalne vrijednosti dobivenih rezultata variraju između 5000 min-1 i 6000 min-1 pa je tako najveća snaga dobivena na motoru s turbopuhalom i hladnjakom zraka i iznosi 175,58 kW pri 6000 min-1. Maksimalni tlak u cilindru je također na motoru s turbopuhalom i hladnjakom zraka te pri 5000 min-1 iznosi 118,13 bar-a. Maksimalna temperatura u cilindru dobivena je na motoru s turbopuhalom i pri 6000 min-1 ona iznosi 1071,3 °C. Maksimalna specifična efektivna potrošnja goriva iznosi 264,84 g/kWh na motoru s turbopuhalom, hladnjakom zraka i waste-gate ventilom pri 6000 min-1. Minimalna specifična efektivna potrošnja goriva iznosi 224,87 g/kWh na motoru s turbopuhalom i hladnjakom zraka, pri 3000 min-1.
Abstract (english)
In this thesis is analyzed naturally aspirated gasoline engine with four in-line cylinders and 110 kW at 6000 min-1. After operating parameters calculation of the base engine it was performed several engine upgrades. The base engine is firstly upgraded with turbocharger, then with aircooler and finally with waste-gate valve. For each engine upgrade were calculated operating parameters in the rotational speed range from 1000 min-1 up to 6000 min-1. For all of engine upgrades, changes in cylinder pressure and temperature were compared. Maximum values of obtained results vary between 5000 min-1 and 6000 min-1. Maximum engine power of 175,58 kW was obtained with turbocharger and air-cooler at 6000 min-1. Maximum cylinder pressure of 118,13 bar was obtained with turbocharger and air-cooler at 5000 min-1. Maximum cylinder temperature of 1071,3 °C was obtained with turbocharger only at 6000 min-1. Maximum brake specific fuel consumption of 264,84 g/kWh was calculated at 6000 min-1 with turbocharger, air-cooler and waste-gate valve, while minimum brake specific fuel consumption of 224,87 g/kWh was calculated at 3000 min-1 with turbocharger and air-cooler.
