    This is the BURN program   Version  5-DEC-1995


The outer loops are:

1. Loop over an RPM range from  rpm_min  to  rpm_max  in steps of  rpm_inc.

2. Loop over a range of spark advance from  min_adv_deg  to  max_adv_deg
   in steps of  inc_adv_deg.

Now at each combination of RPM and spark advance do the following:


   Show the Energy Output which is:


              +180                              TDC

   Output  =    |  Delta_Vol * Ave_Pres    -     |  Delta_Vol * Ave_Pres

                        Vol_head plus Vol_cylinder, i.e. Total Volume
     Comp_Achvd(i)  =  --------------------------------------------------
                        Vol_head plus Vol left in the cylinder at time i


     Perc_Burn(i)  =  percent of fuel burned since ignition i msec ago.

   	
   	
   	 A typical Exhaust Gas Temperature is 1400 Deg F.


The program asks for the name of an output file and a number of other 
parameters:

     Output file name
     Compression Ratio
     Stroke
     Connecting Rod Length
     Minimum RPM
     Maximum RPM
     RPM Increment
     Minimum Advance
     Maximum Advance
     Advance Increment
     Integration Step Size

Then with each loop the program writes to the output file the following
information:


This program uses the following functions:

     Integrate at this RPM and Advance

     Preasure at this step

     Compression Achieved

     Percent Burned
