ABSTRACT

Internal combustion engine studies still continue while electrical cars can be seen on the streets. One of the subjects of these studies is combustion. Due to incomplete combustion, harmful exhaust emissions are formed and the combustion efficiency decreases. In order to increase combustion efficiency to produce a proper equivalence ratio well mixing of fuel and air is essential. The motion of the fluid inside the cylinder has significant effect to satisfy mixing. Nowadays, indigenous studies are conducted on design of high-power diesel engines. In this study, the effect of the geometry of the diesel engine's intake valve on the air flow has been investigated numerically. The fluid motion for different intake valve geometries was simulated using the commercial computational fluid dynamics (CFD) software. As the air flow is turbulent, the realizable k-ε turbulence model was used. The results were presented in velocity contours and velocity vectors. The motion of air flow around the valves was interpreted.
