Well I am getting into how engines work and am trying to learn.
I was wondering if there is a formula I can follow to find out how much more pressure is applied on the piston end towards the cylinder walls if the rod ratio is steeper.
I want to compare a 1.59 Rod Ratio (347 cubic inch) to a 1.66 Rod Ratio (331 cubic inch).
What information would be needed.
I have the piston/connecting rod weights and measurements.
347 – 3.40 in. stroke with a 5.4 in. rod.
Piston weight is 474 grams. Rod weight is 620 grams.
1.59 Rod Ratio
331 – 3.25 in. stroke with a 5.4 in. rod.
Piston weight is 472 grams. Rod weight is 620 grams.
1.66 Rod Ratio
Do you need to know the crankshaft weight?
Any formulas out there to help predicate or give a good idea how much more thrust/pressure is applied towards the outer cylinder wall.
Thanks for any ideas
