Induction Swirl Ratio in D.I. Diesel Engine 891326
This study aims to investigate the optimum swirl ratio in a
direct injection diesel engine. The method of optimizing the
induction swirl ratio of theoretically examined and experiments
with induction swirl ratio from 2.25 to 2.45 in a six cylinder
naturally aspirated direct injection diesel engine are conducted.
The induction swirl ratio is measured by steady-state flow test rig
with a paddle wheel anemometer.
As a result of this investigation, the optimum induction swirl
ratio can be determined by the calculation of the velocity of fuel
spray jet. The results of theoretically calculated swirl ratio show
good agreement with the experimental results reported herein.
