Abstract:V magistrskem delu je obravnavana optimizacija sesalnega kanala motorja z notranjim zgorevanjem in direktnim vbrizgom goriva v valj s pomočjo uporabe računalniške dinamike tekočin. Cilj dela je bil povišanje pretočnega števila in T-vrtinčnega števila z optimizacijo geometrijskih parametrov za celoten režim delovanja sesalnih ventilov. V ta namen smo določili in validirali numerični model sesalnega kanala ter določili najvplivnejše geometrijske parametre. Parametre smo variirali v sklopu optimizacije, ki je bila izvedena zgolj za dvig ventilov za 12.1 mm, pri katerem smo dosegli 0.51-odstotno izboljšanje pretočnega števila in 0.95-odstotno izboljšanje T-vrtinčnega števila. Za celoten režim delovanja sesalnih ventilov se je v povprečju pretočno število povišalo za 0.45 % in T-vrtinčno število za 1.93 %.

Title:Intake port optimization of gasoline direct injection engine
Abstract:In scope of this master thesis the focus is set on geometrical optimization of a GDI IC engine intake port with use of CFD. Goal of the thesis is to increase both discharge coefficient and tumble for the given intake port at all valve opening positions. In order to reach the goal, we have defined and verified the base numerical model. The most influential geometrical parameters were defined and varied in scope of parametric optimization that was done for 12.1mm valve lift and reached 0.51% improvement of discharge coefficient and 0.95% improvement of tumble. For all valve lift positions we have reached an average of 0.45% improvement of discharge coefficient and 1.93% improvement of tumble.
Keywords:Intake port, Parametric optimization, Adjoint solver optimization
