Steady state and dynamic spray characteristics of compound silicon micro machined port fuel injector orifices have been analyzed. Primary interest was placed on the Sauter mean diameter and the spray distribution. Orifice design parameters that influence droplet size and spray distribution were identified. The influence of injection pressure was investigated.The results of this investigation indicate that spray characteristics can be controlled by orifice geometry. Peak dynamic droplet sizes have been found to be significantly larger than steady state droplet sizes. Moderate increases in injector line pressure reduce spray droplet size without significantly affecting spray distribution.
