“…In previous research data, it was said that installing swirl generator increases the swirl performance but decreases the volumetric efficiency. 4,[19][20][21] HSSIV proposed in this study is considered to be an effective method to increase the mixing performance of air and fuel and to increase combustion efficiency by increasing the swirl ratio and TKE without having a negative effect on the volumetric efficiency from its geometrical characteristics.…”

In this paper, we proposed a method to increase the mixing performance of gasoline and intake air by attaching a helical-spiral shroud to the intake valve. The effect of the height and revolution number of helical-spiral shroud on the generation of swirl in the engine cylinder are analyzed. The height is 20 and 25 mm, and the revolution number is changed to 1 and 1.5 turns. A three-dimensional simulation model using the shear stress transport k–ω model is used as the turbulence model to predict the air flow characteristics through the intake valve and engine cylinder in the intake and compression strokes. As a result, the helical-spiral shroud intake valve (HSSIV) generally increases the swirl ratio compared to the general valve, and the swirl ratio in the HSSIV with a height of 20 mm and revolution number of one turn has a maximum value of 77 around 90CAD. It also shows that HSSIV has little effect on the volumetric efficiency reduction while increasing the swirl ratio from different geometrical properties than the conventional shroud valves.

“…Reddy 21 performed an experimental study on the engine performance using three designs of inlet manifolds, helical, spiral, and helical–spiral. Sharma et al 22 performed experimental and theoretical analysis for studying the effect of using inlet valve with two shrouds and inlet valve with rotating fins on diesel engine performance.…”
