Jeff,

Any chance of getting a copy of your spreadsheet?
I am setting up a basic spreadsheet myself to attempt to determine chamber 
pressure for some FEA on the eccentric shaft.
I am trying to model the combustion but have found that the fuel burn rate 
(currently guessing curves) has a major affect on the pressure and 
temperatures inside the chamber.  Do you have any ideas 
on how to get a basic burn rate?
Any help would be greatly appreciated.

Regards,

Kevin Q
