Default Combustion in KIVA

An engine simulation is being run using KIVA. The fuel is being injected at 372 degree crank angle, however, I did not see any combustion occurs. Is there anyway I can correct the situation?

I sincerely appreciate if anyone could provide assistance or advice on the issue.

I did some engine combustion simulations. At first I did not notice that combustion occured. I turned on the monitor routine (ncmon = 5), and then observed temperature and pressure raise, and species variation. I used the equilibruim and kinetic reaction coefficients from the example 1. The tcut and tcute values can also be the reason for which combustion did not occur. The temperature in the cilinder must be enogh high to start combustion. I did only compression ignition simulations. For spark ignition, there are the spark data that can be critical.
