Interesting comments. I would have thought that with the stroke being the same, irrespective of rod length, that the piston must travel the same distance, and thus acceleration from TDC to BDC remains at 180 degrees and total distance travel is equal to stroke. With time and distance being equal irrespective of rod length then acceleration and deacceleration would be consistent with different rod lengths. Changing the stroke would affect acceleration and deacceleration as the distance travelled in the same time period (180 degrees of a revolution) the piston would have to accelerate quicker to move through the increased distance (increased stroke) in the same time period.

My thoughts, maybe my understanding of physics is skewed?
