I was wondering if anyone could tell me or show me how to calculate the pressure inside the cumbustion chamber of a Briggs and Stratton 5hp engine. This calculation is done at 3800 rpm. Thanks

This is a complex question, and the pressure doesn't stay constant at any point during the combustion cycle.
Mean Effective Pressure is calculated by:
MEP = 1000 * (P * Nr) / (V * N)
Where MEP is in kPa, P is power in kW, Nr is the number of crank revolutions per power stroke, V the displaced volume per cylinder, and N the number of cylinders.
Note that the peak cylinder pressure will be much higher than this, but the calculation of this is far more involved.

Thanks a lot this will really help with what we are doing
