Atomization refers to the process of breaking something down into smaller, individual parts or components. It involves taking a whole and dividing it into tiny, separate pieces, similar to breaking a big object into smaller ones.
Perhaps with very clever mapping they can be pulsed as opposed to simple opened and closed leading to better atomization of fuel. (mechanics.stackexchange.com)
The valves are cut to allow air past even when fully - closed, but since they restrict the cross-sectional area of the intake runners, the velocity of the incoming air is increased, resulting in better fuel atomization in idle and low - engine - speed conditions. (fordauthority.com)
Port fuel injection gets good atomization and mixing as the intake valve opens and turbulence distributes everything into the cylinder. (greencarcongress.com)
