Abstract

Zadatak rada je eksperimentalno i simulacijski analizirati promjene u značajkama rada Dieselovog motora uslijed izmjene radnih uređaja motora i upravljačkih mapa računala motora u svrhu povećanja efektivne snage motora. Simulacijska analiza rada motora rađena je u programskom paketu AVL Boost. Eksperimentalna analiza rađena je na stvarnom vozilu pomoću mjernih uređaja opisanih u radu. Prvi korak rada izrada je termodinamičkog modela originalnog motora u programskom paketu AVL Boost. Termodinamički model rađen je po uzoru na stvarni model i karakteristike motora u modelu detaljno su uspoređene s karakteristikama stvarnog motora. Nakon toga je provedena izmjena određenih radnih uređaja motora, kako na stvarnom motoru, tako i na termodinamičkom modelu motora. Rezultati dobiveni simulacijom i mjerenjem ponovno su uspoređeni. Dodatno, provedena je i simulacijska i eksperimentalna usporedba ubrzanja vozila prije i nakon modifikacija motora. Na kraju su analizirani dobiveni rezultati.

Abstract (english)

The objective of this study is to experimentally and through simulations analyze the changes in the operating characteristics of a Diesel engine resulting from modifications to engine components and engine control unit maps, with the aim of increasing the engine's effective power output. The simulation analysis was conducted wusing the AVL Boost software. Experimental analysis was performed on a real vehicle using measurement devices described in the study.
The first step of the study involved developing a thermodynamic model of the original engine in the AVL Boost software. The thermodynamic model was created based on the real engine, with its characteristics being thoroughly compared to those of the actual engine. Subsequently, certain engine components were modified, both on the real engine and in the engine model. The results obtained through simulation and measurement were then compared again.
Additionally, a comparative analysis of vehicle acceleration before and after the engine modifications was conducted, both through simulations and experimentally. Finally, the obtained results were analyzed.
