Sprays from an injector with a conical oscillating poppet, as used in some direct-injection stratified-charge engines, have been characterized. Instantaneous injection pressure, poppet lift and the axial component of the drop velocity were measured, and backlit photographs were taken. Hexane and nitrogen were used. Pump speed, amount of injected fuel, gas pressure, and gas temperature were varied.
