Abstract:Pri razvoju motorja se srečamo z raznimi konstrukcijskimi in energetskimi izzivi, njihovo analizo in reševanje pa nam omogoča napredna simulacijska programska oprema. V diplomskem delu je poudarek na optimizaciji obratovanja dizelskega motorja pri različnih okoljskih pogojih. V nalogi so prikazani rezultati numeričnih simulacij motorja pri različnih okoljskih pogojih. Prikazana je tudi optimizacija izbrane kritične točke ob upoštevanju posebnih omejitev delovanja. Izkazalo se je, da samo z optimizacijo kritične točke ob doseganju enakega navora motorja ne izpolnjujemo zadanih omejitev. Ob vpeljavi pomožnih sistemov, kot je povratno vodenje izpušnih plinov, pa lahko izpolnimo zadane omejitve in dosežemo višji navor. Rezultati so pridobljeni z simulacijo modela motorja, ki ga je posredovalo podjetje AVL v njihovem programu CruiseTM M .
Keywords:dizelski motorji, optimizacija, numerični model, matematični model, kritična točka, VTG, EGR.

Title:Analysis and optimization of engine operating parameters for operation under different environmental conditions
Abstract:In engine development, we may encounter various design and energy challenges. Analysis and solution of these challenges is enabled by advanced simulation software. The thesis focuses on optimizing the operation of the diesel engine under different environmental conditions. The thesis presents the results of numerical simulations of the engine under different environmental conditions. The optimization of a selected critical point is also shown, taking into account specific operating constraints. Results show that, with a base optimization of the chosen critical point, we do not meet the given limits when the same engine torque is achieved. With the introduction of auxiliary systems such as exhaust gas recirculation, we can meet the set limits and achieve even higher torques. The results were obtained by simulating an engine model provided by AVL in their CruiseTM M program.
Keywords:diesel engine, optimization, numerical model, mathematical model, critical point, VTG, EGR.
