Renault R26 Breaks Cover!

[acer]

I noticed that the nosecone in wider on the R24.....compared to the MP4-19...mclaren's is smaller....usually seen in 2004..and it's back again in 2006

Acer click on that link, second picture, it explains why they changed the nose

Does anybody know what this device on the end of the camshaft of the R26 engine is? It's on the exhaust camshaft. I guess it could be a cam position sensor, but I'm not entirely sure. It looks like it could be hydraulic because it's a little bit like a snail shape. Jeez, do you think six bolts is enough?

[axle]

That is odd...almost like it's got a cam controlling motor for say VVTi...when they don't have cams!

Pressure or heat sensor?

[ginsu]

What do you mean 'they don't have cams'? Of course they have cams.

[axle]

Oh bugger...I thought they were hydraulicly actuated in and out? Which allows for the hat stand rpms?

Are they not then?

I believe it is an oil scavenge pump.

No. F1 engines have pretty standard looking camshafts. The valves are buried under pistons for the pneumatic valvetrain. The camshaft operates on a finger follower that directly acts on this piston.

That sounds right. It could be driven directly by the end of the camshaft. Since the oil might pool near the bottom of the head because of the V-angle. I know it's very important to keep all the oil circulating all the time, no pools should build anywhere in the engine.

Seen this now http://scarbsf1.com/valves.html - whoops

Something similar to the Lotus engine on a dyno with an electromagnetic valve train system that I saw years ago will hopefully replace the cams completely...eventually...thus helping their evolution into modern mass produced engines.

That Renault's camless project from scarbs site was never applied in F1.
Here you have pics of F1 cams;

Some nice pics of R26

You didn't have to post everyone of them again Ranger, think of the poor soles on dial up!! Classy pibs BTW Manchild.

I've just added pics of the R26 in my Renault section, you already know some of them as they're Renault media photos but maybe you did not see the focus on certain parts of the technical drawings, that's here :

I got this picture from your R26 section and I'm wondering how this mono spring rear suspension works. Is there a torsion bar inside each rocker as well? So what's that central spring for???

Thank you!
