MODENAS CT115s intake port performance enhancement through analyzing volumetric and geometrical design with valve lift adjustment by using CFD Simulation

[摘要] This paper reviews improvement of intake port for Modenas CT115s by using CATIA software for the design and ANSYS software for the simulation result. Intake port is referring to the passage in the cylinder head which connect the intake manifold to the intake valve through which the fuel-air mixture proceeds on its way to the cylinders. The results obtained has been analysed and interpreted in formed of plotted graph. From the analysis, increasing the inlet of the intake port size can increasing the volume flow rate. The main impact is high angle of intake port that can give high torque and power. The decision to choose the proper angle for the each design is important because it will affect the major result for the simulation. Thus, it can be concluded that the increase of the inlet size and using the best angle of the intake port can increase the engine performance which allow higher fuel-air mixture entrance during the combustion process.
