However, controlling, calibrating, and subsequently optimizing high-performance engines in which the trade-offs between performance, economy and emissions take precedence, is a challenge for even the most experienced automotive engineers, as it includes major implications. With the rise of fuel prices however, in recent years, more and more transport companies and fleet owners have looked to improve their vehicles’ economy through different aftermarket optimizations of the vehicles` engines, rarely taking into account the impact of such changes on the overall balance imposed through the environmental-engineering compromise. This paper investigates the required changes into the engines` electronic control units to achieve higher power output and lower fuel consumption, while analyzing the benefits and shortcomings brought by these optimizations on the engines` short and long-term operationNovi motorji z notranjim zgorevanjem imajo številne sisteme, ki zagotavljajo boljše delovanje, hkrati pa izpolnjujejo vse strožje okoljske norme in standarde emisij izpušnih plinov v tako imenovanem okoljsko-inženirskem kompromisu. Vendar so krmiljenje, umerjanje in posledično optimiziranje visokozmogljivih motorjev, pri katerih imajo prednost kompromisi pred zmogljivostjo, ekonomičnostjo in emisijami, izziv tudi za najbolj izkušene avtomobilske inženirje. Zaradi dviga cen goriva si v zadnjih letih vse več prevozniških podjetij in lastnikov voznih parkov prizadeva izboljšati ekonomičnost svojih vozil z različnimi poprodajnimi optimizacijami motorjev vozil, pri čemer le redko upoštevajo vpliv takih sprememb na splošno ravnotežje, uvedeno s kompromisom okoljskega inženiringa. Ta prispevek raziskuje potrebne spremembe v elektronskih krmilnih enotah motorjev za doseganje večje izhodne moči in manjše porabe goriva, hkrati pa analizira prednosti in pomanjkljivosti, ki jih prinašajo te optimizacije na kratkoročno in dolgoročno delovanje motorjevTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Mariboru, Fakulteta za energetiko
