26-45 ANALIZA POSIBILITĂȚILOR DE ÎMBUNĂTĂȚIRE A PARAMETRILOR DE PERFORMANȚĂ A UNUI MAS SUPRAALIMENTAT PRIN MODIFICAREA FAZELOR DE DISTRIBUȚIE


ANALYZING THE POSSIBILITIES OF PERFORMANCE IMPROVEMENT OF A CHARGED SI ENGINE BY MODIFYING IT’S DISTRIBUTION PHASES
This paper aims to analyze the possibilities through simulation of performance parameters improvement (mean effective pressure, boost pressure, exhaust flow and engine speed increase to sudden load change) of an engine to its basic version. As simulation software, AVL BOOST was elected, which gives the required accuracy for transient simulations. Simulations compared the engine performance of the various possibilities of amending phase distribution compared to the basic version of the analysed engine. Keywords: performance, distribution phases, simulation, charged
