Macro-spray structural parameters and micro-droplet of diesel-FAME under the circumstance of different FAME content, injection pressure and nozzle diameter were studied. With the increase of FAME content, the spray penetration increases, and spray angle decreases, molecules viscous force and the micro-droplet size increase, which means the atomization getting worse. With the increases of injection pressure, the penetration increases, the spray angle decreases. The more FAME content, the greater
more » ... the rate of them. The microscopic droplet size decreases as pressure increasing. With increased nozzle diameter, the cavitations of liquid become weak, the penetration extends, and the spray angle decreases. Droplet size becomes bigger and atomization gets worse.
