Hi Danlp6, im sure your going to read this at some point. i just had a look at your car, nice one to! however its not a mk1 now is it! tut tut. lol.

laterz

 

[clio__chris]

huh? its a mk1 172...... as they were the 1st 172s built

 

[The Fatty]

ohhhhhhhhhhhhhh i see! its not a mk1 clio shape tho! i understand how it put now tho!!!!!!!!!!!!! its the first of the 172s! did they not use the 172 engine in the real mk1's?

Sure;y its still a mk2 phase1 172....?

 

[cK]

It's a Mk1 172 same as mine.

Mk2 = this shape http://www.cliosport.net/index.php?ind=gallery&op=foto_show&ida=48

Mk2 Phase1 172 == Mk1 172
Mk2 Phase2/3 172 == Mk2 172

 

[The Fatty]

thanks daz....So it is a MARK BLOODY 2!!!!!!!!!!! (clio)

why they bother calling it a mk1 again? its a phase, not a mk. it should be mk2 ph1/ph2/ph3....else it just get confusing!

Also, how does VVT work?

 

[Lagerlout]

Technically speaking its a Mk2 Phase 1 172.

Although the colloquialism on here for it has become Mk1 172.

 

[Dan@SJM]

Lol you worried me!

The VVT Just operates on oil pressure on the Pulley, adjusting it like a vernier pulley!

It switches over at 1400rpm at 800mb vacuum.NOT t 4-5000 like its sometimes said.

lol, how long ago did this mistake become permanent though lol.

VVT works via a phasing device on the inlet cam. The camshaft is hollow and oil pressure is fed to the phaser through the nose of the cam. Oil pressure is prevented from entering camshaft via a plunger (valve) in the oil galley which feeds the clearance pivots for the roller path followers. The ecu triggers the valve which opens pressure from the galley to the cam, which feeds upon one side of a set of vane inside the phaser and advances the camshaft relative to crank position.

In the case of the clio 172, this is above 1450rpm and above a manifold pressure of 800mb.

wow. thats really quite kool. wish my car had that! (saying that, i just wish my car worked!)ncan you feel it "kick in" as such? or is it smooth? my sisters mgf and rover had it, but i could never feel diff, im not sure rover got theres working properly tho. and i think they called it vvc (or is that something else entierly??)

 

[Dan@SJM]

vvc is variable valve control. same thing, and no you cant feel it. you feel a kick at 5000 which is the cams coming into optimum profile.

 

[Lagerlout]

Not to be confused with the Honda VTEC systems, which you can feel - as I understand it it changes to a 'wilder' cam at a given rpm and doesn't simply alter the phase of the cam as the Renault system. As I understand it anyway.

I wish I had a CTR engine in my Clio. lol.
