Abstract
This paper is dedicated to the study of sprays in the framework of manifold injection in an S.I. engine. Modelling of spray is considered and laser-based techniques were used to characterise droplets in an engine, and a simulated arrangement was built to maximise optical access for the phase-Doppler anemometer (PDA). The applications are, successively, a free air spray, a steady flow-rig and a cylinder-head without and with running camshaft A strong correlation between cold-flow simulation obtained with an open-ended tube downstream the cylinder-head, and the motored engine is obtained in terms of droplets behaviour, concentration and trajectories. The quality of the air/fuel mixture is described by these means, in terms of the extent of non-homogeneity.
