: engine question??

07-08-2012, 09:15 PM
I remember seeing a BMW I6 engine with the heads off and the pistons seem to be firing in pairs(??).:dunno:

I tried to look this up and the only thing I was able to find was that this style is generally called "big bang". (if indeed it is the style used here)

The overall result is that you would effectively have 3x2cylinder engines working together.

I assumed that it was a smooth timing but maybe it's not.

Any ideas or pictures??
