An AVL BOOST software for engine process simulation

Sve stroži propisi o zaštiti okoliša, a i potreba za što boljim iskorištavanjem goriva postavljaju pred konstruktore motora sve veće zahtjeve. Razvoj numeričkih metoda, a istovremeno i porast snage računala omogućavaju provjeru novih ideja još u ranoj fazi razvoja motora. U radu je dan pregled mogućnosti programskog paketa AVL-BOOST firme AVL iz Graza. Opisano je grafičko sučelje koje omogućava korisnicima s osnovnim znanjem o simulacijskoj tehnologiji da u kratkom vremenu ovladaju programom. Predstavljen je model jednocolindričnog motora, izvršena je simulacija rada te analizirani dobiveni rezultati.The more and more rigorous regulations on the environmental protection, as well as the need for a much better fuel exploitation, have raised greater demands on the designer. The development of numerical methods and, at the same time, a computing power growth, makes the checking of new ideas possible, even in the early stage of the engine development. The paper aims at presenting a survey of all the possibilities offered by the AVL-BOOST software produced by the firm AVL from Graz: A graphical interface, that enables the user with only a basic knowledge of a simulation technology to master the computer programme in a very short time, has been described too. A one-cylinder engine model has been presented and its operation simulated. The results thus obtained have been analyzed
