Power increase of a diesel engine

U ovom se radu orijentiralo na pogled povećanja snage pomoću prednabijanja turbouhalom uz termodinamičke proračune i simulacije u programu. Prvo, krenulo se kroz termodinamičke proračune gdje je prednost imao proračun bez prednabijanja i svaki se korak detaljno računao. Poslije toga išao je proračun sa prednabijanjem u kojemu smo vidjeli za koliko se snaga povećala mijenjajući pojedine parametre. Tijekom proračuna vodila se briga i o ostalim vrijednostima osim snage, momenta, toplinskih tokova, specifične potrošnje goriva, protoka zraka i drugih. Nakon teoretskog dijela prešli smo u program koji provodi simulacije. U njemu smo isto kao i gore provodili dvije odvojene simulacije. Prilikom očitavanja rezultata simulacije odmah se uspoređivalo sa vrijednostima dobivenim u proračunu te njihova odstupanja. Na kraju su se uspoređivali prednosti i nedostatci prednabijanja turbopuhalom i došlo je do zaključka kako turbopuhalo ima veliku korist na motoru sa unutarnjim izgaranjem.This paper focuses on viewing the increasing power by pre-charge turbocharger with thermodynamic calculations and simulations in the program. First, it went through thermodynamic calculations where the advantage had a calculation without pre-impaling and each step was counted in detail. After that went the calculation with pre-impaling in which we saw by how much power increased by changing individual parameters. During the calculation, other values were also taken into consideration other than power, torque, heat flows, specific fuel consumption, airflow, and others. After the theoretical part, we moved on to a program that performs simulations. In it, we conducted two separate simulations. When reading the results of the simulation, it was immediately compared with the values obtained in the calculation and their deviations. In the end, the advantages and disadvantages of turbocharged pre-charge were compared, and it concluded that turbocharged has greater benefit on the internal combustion engine
