Abstract

The combustion concept reported in the first report needs fine atomization and low penetration spray. The new nozzle for both demands is applied new technology, based on a slit nozzle. First, the shortening of nozzle hole length to utilize flow turbulence generated at nozzle hole inlet. Second, the installation of the projection shape on the needle tip as the rectifier to control the vortex in sac. In addition to the foregoing items for lower penetration , angle of nozzle hole is enlarged to reinforce spray momentum dispersion. As stated above, the developing nozzle which is improved by the based on inside nozzle flow has achieved the spray performance which can adapt to the new concept and engine performance target.
