Multi-valve technology

What a lovely wee row of poppets..

You should remove that picture, it might be considered porn and have this site shut down

[J.A.W.]

Or here's an idea to market as "F1 Art"..

Coat the head gasket face with paint, put more paint in the ports, lay it while wet on a canvas ( or fresco, paper & etc),
then give the valves a sharp tap with a hammer, & remove.. ..to reveal the flow pattern spray in all its glory..

Remember guys - you read it here first, (for intellectual property royalty purposes).. ..L.O.L...

Do you have a picture of the cams used with that cylinder head?

[gruntguru]

No - but there are five of them with direct acting buckets.

Seriously r-r..
..you surely cannot..
.. actually believe..
..that..
..such an image..
..has any material reality..
..outside of a photo-shop ?

Not.. quite.. my concept C-B,( but still artistic for sure) ..so.. ..you might've got away with that one.. ..L.O.L...

Yes J.A.W., I grasped the fact that the cylinder head image was Photoshop'd. And I hope you grasped that my question about the camshaft was also asked in jest.

Frankly, I was hoping some clever person would put together a composite image of a twisted/convoluted/forked camshaft that somehow mated up with all four of the different valve arrangements.

Cheers.

[J.A.W.]

Yeah, right.. r-r, of course you were..

Actually, I'd reckon Honda might take on that task as one of their wacky engineering competitions..
( 8 valve oval piston anyone?)

& having worked on a few of their wacky production rocker set-ups, I reckon it'd be right up their alley too..

Dual underhead cams with pushrods. One either side of the block.

[J.A.W.]

Just like an old Riley, or Triumph Speedtwin..

Although Honda have made a few pushrod mills too, including their then super-tech turbo CX 500, back in the `80s..

I ran a competition SOHC 4-valve per cyl Yoshimura-cammed Honda that habitually broke rockers under the strain..

Whoever created that photoshop image actually put a bit of thought into it. All of the intake and exhaust valves are located on the correct side of the cylinders.

[J.A.W.]

Fairly bloody self evident, really, r-r, aint it?

Not that every deep breathing poppet valve head has to be - per se - cross-flow..
