## Main Question or Discussion Point

I'm currently doing a report on Petrol Engines and I'm having a problem with my results not making sense.

Am I correct in saying Break mean effective pressure (bmep) should increase as Engine Speed (rev/min) increases? My results do not reflect this and I don't understand why.

I have attached my results table below, I calculated brake power and bmep myself using these equations:

I believe the problem is in the Brake Power & bmep results, help is much appreciated.
