SHRNUTÍ Tematem tohoto članku je zkoumani možnosti kompenzace kolisani kvality paliva kombinaci několika regulačnich zasahů najednou. Takto jsou odvozeny pokyny, jak zajistit flexibilitu motoru ohledně paliva co nejefektivnějšim způsobem. Za potencialni regulačni parametry jsou uvažovany uhel předstihu zažehu, nastaveni plniciho tlaku a poměr recirkulace vyfukovych plynů. Matematicka simulace je použivana jako preferovany způsob zkoumani s cilem ziskat co nejvice obecne vysledky. Použivane simulačni nastroje byly kalibrovany pomoci experimentalnich dat z testovaneho motoru.

The article is focused on a 1-D drive dynamic simulation of a highly turbocharged gas engine. A mono fuel CNG engine has been developed as a downsized replacement of the diesel engine for a medium size van. The basic engine parameters optimization is provided in a steady state operation and a control adjustment is applied to a dynamic vehicle model for a transient response improvement in highly dynamic operation modes of the WLTC (world light duty test cycle), selected for investigation. Vehicle simulation model with optimized control system is used for driving cycle fuel consumption and CO2 emissions predictions compared with the basic engine settings.
