Abstract
This article presents an analysis of mixer insulators on the gasoline engine to find the most optimal design. A standard insulator has been redesigned by adding a scrambler of air flow placed in the intake manifold. Simulations are carried out on 10 variations, which include standard insulators, 5, 7, and 9 angled insulators which have slopes of 30°, 45° and 60°, and have a thickness of 5 mm. Each model was analysed using Computing Fluid Dynamic (CFD), with parameters of air velocity 10 m/sec and air pressure 101325 Pa. Simulation results show that mixer insulators with a thickness of 5 mm, 5 blades with a 45° slope angle produce the best turbulence intensity. Meanwhile, another design with a thickness of 5 mm, 9 blades with an angle of 60° slope angle produce the best effect to increase air velocity.
