Breakup characteristics of diesel spray droplets under small valve opening injection
Nihon Kikai Gakkai ronbunshu, 2016 A laser 2-focus velocimeter (L2F) was used for measurements of velocity and size of droplets in diesel fuel sprays. Diesel fuel was injected intermittently into the atmosphere using a 8-hole injector nozzle. The diameter of the nozzle orifice was 0.112mm.
