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!
