[Rudolf Diesel]

I am trying a combustion simulation of diesel engine under the following settings.

I compared a pressure history between a simulation and a experimental.
However I don't get a agreement at the ignition delay period.
I tried to change some parameters,but i never get ignition delay from simulation.

How can i get a ignition delay from simulation?
Please help me.
