Hey BvU Thanks, (Have a look at what I said to Irene's reply). There's defiantly weight in what you said about adding an extra measurement at TDC. In an engine, the firing occurs a couple of degrees before TDC (varies from manufacturer), a force is applied to the piston which can't go any...

Hi Irene I like your suggestion, the last time I did stats was in the 1980s. I would be interested to see the result if you ran the figures. Con't stop thinking that an effective average would give a more accurate result. A bit like the rifle bullet accelerating down a barrel, versus a...

Here are the rest of the distances and forces: 17 mm 18 mm 19 mm 20 mm 21 mm 22 mm 23 mm 24 mm 25 mm 26 mm 27 mm 28 mm 28 mm 29 mm 30 mm 0.9 Kg 0.8 Kg 0.7 Kg 0.6 0.6 Kg 0.5 Kg 0.5 Kg 0.4 Kg 0.4 Kg 0.3 Kg 0.3 Kg 0.3 Kg 0.3 Kg 0.2 Kg 0.2 Kg

Hey BVU Correct, any force still around at BDC is waste. BDC is 30 mm and the force is 0.2 Kg so insignificant. I did not put the last figures in because they are easy to include once I understand the solution. I'm old school, pensioner, specialized in rotor dynamics and balancing so very grey...

1. How do you calculate the average force on a piston in one stroke from TDC to BDC given the following Kg forces and their distances in mm from TDC? 1 mm 2 mm 3 mm 4 mm 5 mm 6 mm 7 mm 8 mm 9 mm 10 mm 12 mm 13 mm 9.9 Kg 7.8 Kg 6.3 Kg 5.3 Kg 4.4 Kg 3.8 Kg 3.2...

Hi Guys New mwmber Thanks for the welcome. I retired as a Rotor Dynamics Engineer, and I have found and interest in engines, steam and internal combustion engines. My two brain cells are very rusty and so I joined to see if I can get some help from you guys. Kind regards Tony
