VTEC = variable valve timing & electronic shift control
MIVEC = Mitsubishi intelligent variable valve electronic shift control
VVT-i = variable valve timing - intelligent
DVVT = dynamic variable valve timing

and finally
CPS = cha piah sistem

One of the the purpose of forum is to share experiance and knowledge.
There is no 100% correct or wrong.

Btw, appreciate if all of u can stick to the topic. U all may back to CPS, VVTI & DVVT technology road map.

Guys,

my cps FC is improve after feed with Vtec -LEV.
I strongly believe that good FC on Honda i-VTEC is closely relate with engine oil.
Now my FC is 450km++ @ RM60
Petronas Ron95.

 

[Newbienissan]

hmmm, 450km for RM60 is quite good. thanks for sharing

 

[GSR06]

BTW, how does the dual VVT-I work on Altis? For the new Hyundai Sonata, it has dual CVVT with 163hp & torque at 198Nm for a 2L category. Also, the block or pistion is Aluminium alloy,something similar to Vios's technology. I have heard Vios travelling mostly on highway can reach more than 600km in a full petrol. Not sure about what speed it's travelling though.

hi all,

for FC, shall we use units like liter/100km, or km/liter instead of RM/km?
easier for FUTURE reference.
cause the petrol price keep changing.
RM60 RON95 for 450km (RON95 = RM1.85/l)
= 7.2l/100km
= 13.88km/l

dear gsr06,

we are here to discuss technical n experience, once step out in realife, nobody meets nobody from the forum, not in a million years unless purposely held up a tt. so i dont see the point 5115 is trying to busuk my name. in real life wanted to talk just only on the phone with 5115, but was ignore. what is the point not to talk but only busuk other name by only typing words.

plz dont edit or delete this, 5115. forum will never be real life. if dont agree with my opinion no need to bang me this way, moderator. if u 5115 got better experience worth while plz share with me, at least i know u got something n listen to u, not showing off ur power as mod here. according to u 5115, we should treat each other like the way in realife, then u mark ur own words n post maturely n peacefully. dun dig story 2-3yrs old again, like u said in all ur pm u sent me.

lets get on with the topic

 

[GSR06]

Bro, chill down. I appreciate all the sharings up to this point and like what boyzone said, there is no 100% right or wrong in a forum... cheers

haha..

aww come on now.
it's their 1st time doin a variable valve thingy.

hopefully they'll be able to do both cams later on.

wishlist for proton (when they 'technically' grow up later):

-variable valve engagement on both cams

-a better variable length intake manifold to complement the above.

while my previous post explain the difference of CPS (which uses the tappet) vs other cam lifting techno, take note most other techno use rocker arms (VTEC, VVL, MIVEC) to make the cam shifting.

CPS as use in campro cps is similar to porsche variocam plus, just that porsche also have the VVT (like i-vtec)

the middle picture shows "high lift", the little green part in the tappet is engaged, locking the outer and inner tappet. low cam not touching the inner tappet.

picture on the right shows "low lift", the inner tappet seems "protrude" out to touch the low cam in the middle. actually is the high lift cam on the outside pushing the outer tappet down without acting on the valve.

below is a bigger picture showing the "low lift". sliding pin in red not engaging.

the inner tappet ALWAYS contact with the valve.

here is a picture for the campro CPS head (courtesy of kevin from bluedevil76 dot blogspot dot com)
take note that the difference between the high and low cam not as significant as the one in porsche

 

[boyzone]

Is the CPS ori stock spark plug cable serve with silicone?
