  • Rover - Variable Valve Control - VVC
    Copied directly from a dealership VHS video
    If you have any Austin/Rover videos, especially relating to the Maestro and Montego models, we would love to hear from you.
    an informative program on the operation of the VVC system fitted the K Series Engine
    Programme Content
    - An overview of Rover 'K' Series engine
    - Principles of the 4 stroke engine cycle
    - 3D graphics showing the principles of Variable Valve Control
    - How the principles of VVC are transmitted into reality on the 'K' Series engine
    - Cam period variation and increases in power and torque
    - Servicing aspects of the new engine

    this is why i enjoy working on rover engines so much so i now only work on these engines from metros to rover 75 all models and engine ranges. my skills in these engines are in demand.

    Reminds me of a complete head and VVC unit stripdown and rebuild I did on my Coupé with the guidance of the very talented Dave Andrews of DVA Power in Milton Keynes. Taking the VVC units apart was like dismantling a Swiss watch. Over engineering and not without flaws, but pretty ingenious.

      To be fair they’re actually pretty reliable units, considering what it does which is to vary the valve timing throughout the full rev range it’s actually fairly simple but with a couple of finely machined parts. I’ve had way more trouble with air con, turbos and egr valves than with the vvc mech.

    I used to run Full Synth 10w40 in my VVC. I switched back to semi-synth after being convinced by people on the forums.
    After watching this video, I'm even more certain that this was the right choice. The VVC system is controlled by oil pressure and the brains is the MEMS computer which must be calibrated for a certain type of oil. Unlike any other engine I've ever come across, there may very well be a difference between running full synth and semi-synth of the exact same oil viscosity. Weird!

      Ridiculous engineering then,can´t believe that!!! (should not be allowed to be sold to the public) ; i guess that may be caused by another great of the many emissions of the Greenphissers for sure... their emissions... **avoid**

    So Rover actually thought that people who didn't know how a 4 stroke engine worked at the beginning of their 15 minute video would be able to change the head after watching it.
    That must have been some serious drug they where on...
    Still an interesting video though.

    The original idea (substantially replicated by Rover) was patented by a British Corporation, but actually the idea born in Italy (in the late '60): designer was a top manager of the italian branch of that corporation whcih was assigned of the copyright.

      Its not true...original idea born by Mr. Prof. Mitchell in Britain ;-)

    • @andreamanzotti5433
      @andreamanzotti5433 7 років тому +1

      I think you' re wrong: if you like I can address you where (in WEB) the very original patent report may be found. I know this because I do have the original document of it, because patenter was my grandfather. I see that Prof. Mitchell reference is dated in the '80, but original idea (technically exactly the same) had been patented in '67. Copyright of that project was owned by AE Borgo (a British company) for which my grandfather managed the Italian branch. Write to me to amanzotti@flowserve.com (if you like). Nice to hear of you anyway. Regards.

      @@andreamanzotti5433 A patent should never be used as proof of creating something. Its just an old trick with the boys club in industry to hold control and make money off others work. If your grandad is the inventor i suggest you hold on to his working models and cheerish his accomplishments.

      Hi Robert, I do agree. I just cared to clarify about chronology and mostly about what "modernizations" are: even in our daily life we frequently meet old solutions, coming from a forgotten past which are sold as the "newest ones". In Italy we call it: "the discover of hot water".

      @@kennethtucker9844 Hey there, that was what I thought for the first 5 years and 25k miles... My TF160 was bought new from the factory, never driven hard until the oil was up to temperature, always had the correct Magnatec oil changed every year despite the low miles, coolant checked every time it was driven and changed every other year. But, alas, at 5 years I opened the boot to see the coolant was down, I pulled the dipstick and... brown mayo. Fortunately I'd driven no more than a few miles, gently, on the blown gasket and had it transported to Brown & Gammon for repairs.
      That wasn't long after all the MG specialists started offering an upgrade solution with Land Rover Freelander parts, so my TF now has the upgraded oil rail, MLS gasket, upgraded through bolts and I think a couple of other bits fitted and of course I had the head skimmed. I drove it another 2-3 years without issue but since 2012 it's been parked up unused so I can't vouch for the longevity of the repair yet, but I'm just starting to recommission it so hopefully, fingers crossed, the repair is still good... Plenty of other bits for me to do without having to replace the head gasket! Can't wait to get driving it again, lovely little machines.

    This is the best explanation of Varibale valve duration system. The one, which nowdays korean Hyundai called CVVD says, that they are the first in world with such a system of variable timing of combustion engine on the market. But actually, it is not true. The first was Rover.

      Get to know the subject before making comment, the Honda vvc is nothing like this it is basically either 8 or 16 valve in operation at any one time. The Rover vvc is a genuine variable valve control that alters the speed and overlap of the cams. Pure genius.
