I didn't know this till today and I must say I am surprised.

This is the Variocam plus variable valve lift technology used in Porsche engines. Its actually the same system use by by Proton in their Campro CPS engines and its licensed to Porsche. Of course, they say its actually developed by Lotus......

Look at the intake cam profile and compare it with Variocam plus. They are essentially the same. Both systems also use flat tappets with a locking pin to change the cams.

 

Of course, the Proton engine does not have continous VVT implemented, only fixed VVT and VVL similar to MIVEC and early VTEC systems.

Where does it say that this is licensed from Proton?

 

In contrary, in the first link you provided, Porsche claims to have developed Variocam themselves.

 

Quick! Go ask Proton to sue them!!! <_<

Its mentioned in this article. INA is also licensed it.

 

Btw, Variocam is developed by Porsche. Its a variable valve timing mechanism w/o lift control. Only the Plus version has lift control. And this lift control mechanism is licensed from Lotus.

I doubt its true - the monkeys rarely have the initiative to develop anything of their own. Saga, Satria, Perdana , Wira, Juara and Inspira all based on Mitsubishi models . Engines also must use Mitsubishi's [laugh]

 

Most likely this tech was originally from Lotus.

 

Lotus buyover != Proton developing the tech

 

PS: Tiara = rebadged Citroen

sorry... still not seeing it... but once again your first link says it is "licensed from Lotus Engineering" but your topic title says "License from Proton"...

But Proton is the owner of Lotus. So whatever that is owned by Lotus is belongs to Proton too.

I just check around. VarioCam Plus is indeed a variant of the same camprofile switching used on the Campro CPS engine. HOwever, I think its licensed from Lotus rather than Proton cause its Lotus that developed it, not Proton. Proton has access to all of Lotus's technology because they own Lotus.

Like that also can, title so misleading. Make it sound like Proton develop something worthy. But if it makes the TS happy, then so be it loh.

Lotus actually tune the engine themselves and make it even more powerful than the one in the Celica. They even have a supercharged version of the engine.
