I'm not sure really what you're saying - if the cylinders are horizontally opposed then the big-ends need to be 180 degrees out from eachother for each pair. If the block was a 120 degree V then the big-ends would have to be 120 degrees apart for each pair respectively.
A balanced six cylinder requires firing to be 120 degrees of *crank rotation* apart (720[4-stroke cycle] / 6[cyl]) = 120 degrees.
The animation works, the firing order looks like it could be 1,6,3,2,5,4. That would work.
that is confusing. It is showing 3 pairs at what looks like a 6 cyl firing degrees(120)...and each pair is 180 apart. A 6 cyl fires every 120 degrees for a four stroke, how is a flat six with 180 degree pairs of cylinders, in a flat block firable in the above animation? Doesn't it need a 120 degree block to be 180 pairs.I tried to draw one flat out, and could not do the 180 pair thing you got going in animation for a 6 cyl. A gour cyl boxer is in heaven there at 180 degree fires. I confuse me.
the firing sequence is : 1 - 6 - 2 - 4 - 3 - 5, while 1 , 2 , 3 is on the left bank (view on animation) and 3 , 4 , 6 is on right bank going from free end to the flywheel.
Sorry I do not recall all I did but essentially the concept comes from Porsche engines.
All geometry is of Adams but one conrod was made in Catia V5 and preprocessed in Ansys to have flexible body. Also pistons are made by Adams itself (embedded C routine).
i see what the problem is here...its only firing on one cylinder.....hmmm...haha only kiding

Hi,

Feel free to ask if you have any questions.

What CAD programm have you used for the parts?
