Question from a non-expert in the field who is genuinely interested in the topic. Shouldn't the argument (I mean discussion
) focus on the impact of the bore to stroke
ratio for a given displacement instead either the stroke or the displacement on their own?
To me - and I'm absolutely open to correction - basic physics
should dictate that the characteristics and nature of the power delivery of an engine with a big bore and a short stroke would differ from that of an engine of ~ identical other specs that uses a smaller bore and a longer stroke to achieve that same displacement. Naturally, tuning and adjustment of other parameters can compensate, but would the two base combinations not perform or at least feel different to the seat of the pants?
Admittedly this has been my belief based on the above ASSumptions for a long time and I'd be surprised - though happy to be educated - to learn differently.
