Two IC engines with same displacement, but different number of cylinders

[kandelabr]

Homework Statement

The object of this assignment is to find two engines that have the same displacement and different number of cylinders and compare ratio of their power output to a few equations' results.
The engines should be from the same manufacturer and their manufacturing date should be no more than 10 years apart.

Homework Equations

not relevant (not a problem at all)

The Attempt at a Solution

I cannot find two engines with these conditions. Any ideas?

Thanks,

From the same manufacturer... that makes it harder.

But if you look at sportbikes, you will see that two common engine configurations are in-line 4 and V-twin. You could probably find two 1000cc sportbikes from say, Honda, where one is an inline 4 and the other is a V-twin. I'll see if I can find some examples...

This article talks a little bit about V-twin versus in-line 4:

It looks like Honda had the RC51 V-twin, and maybe you can see what inline-4 it has that is about the same displacement...

Yes, that's what I was looking for.
Thanks a lot!

I would suggest looking into the specifications of different engines from the same manufacturer that have the same displacement but varying numbers of cylinders. This information can typically be found through the manufacturer's website or by contacting them directly. Additionally, it may be helpful to search for engines that were released within the past 10 years, as this will increase the likelihood of finding two engines that meet the criteria. Once you have identified two suitable engines, you can then compare their power output ratios using the equations provided in the assignment. It may also be useful to consider other factors such as fuel efficiency, emissions, and overall performance in your comparison. Good luck with your assignment!
