Hey Everyone,

 

So with the announcement of 42083 I have had W16 engines on my mind.  Thought I would make a little rendition of my own.  It is too small for 42083, but it is Technic Figure scale, based on newer proposals of mini-engines that have been around for a while. Complete with the four turbos (at least the appearance of them).  I wish something like this could be in 42083, for based on the promo video I think any proposal with the current engine blocks will be too big, chunky and overall sloppy-looking.

That is absolutely brilliant! Its perfect, and sounds like an engine. Well done!! :wub:

Ingenious! Looks great and runs well - only criticism is that the inner banks of cylinders seem to vibrate quite a lot since they're only supported by the 157.5 connectors.

This is a cool little engine and it sounds great! :thumbup: however if I’m not mistaken I see two crankshafts there, so it’s mechanically incorrect..

Looks good, I just wish I had a common crank. It does sound like an engine.... One that's been drained of oil :tongue:

Nice work on fitting two rows of cylinders.  I tried it last week with this design but it wasn't a success.

Actually, you are partly right.  It really is not both inner banks.... if you look closely  the right side (if looking at a frontal shot of the engine) is actually fairly sound while, you're correct, the left side vibrates a lot. And this is not due to being connected by only two 157.5 connectors, because the right side, as well as the outer banks, are also only connected by the same.  Any idea why the left, outer bank vibrates so much?  Guesses?

Yes, there are two cranks, so both of you are correct, it is mechanically incorrect.  I guess there is a trade off here.... mechanically correct (one axle) or an offset in the cylinders.

I just saw your post.  Looks like we both had similar ideas  :wink:   I guess now the question is if people want to have only one axle or the offset. 

But..... I have a feeling that someone out there is working on a solution and we may have the best of both worlds soon  :wink:

Maybe it's something to do with the direction of rotation of the two crankshafts? If the two crankshafts are rotating in the same direction, because of the symmetry of the engine, one bank will experience different rocking forces to the other.

Very nice engine! If I ever make another supercar I will surely consider this as an engine option!

Curious to see how LEGO's engine compares.

Yup, exactly.  One side the series of thin liftarms are rotating away from the bank whereas the other is rotating towards.  That which the crankshaft rotates towards has much more force (therefore rocking) than the other.
