What is it with Proton? Why so many name? We have the Waja CPS, Persona with IAFM. SO which is which? I know that CPS is Cam Profile Switching..but the rest?
Why so many names?then what about the previous generation Waja Campro? or GEN-2 Campro?

maCampro

yeah i wonder why too?

Because simply its -----> Buatan MALAYSIA?

Malaysian like buzz word, eg VVT-i, DVVT, VTEC, IAFM, CPS, lol.

IAFM mean what?

Here you go..

IAFM = ! M Fat Man

more info here:
http://en.wikipedia.org/wiki/Campro_engine

For those lazy ppl, i'll try to summarize. There are 3 Campro engines out there:
1. Plain old CamPro (all proton cars after Waja and before New Saga)
2. CamPro IAFM (New Saga and latest batch Persona)
3. CamPro CPS (Gen-2 CPS and Waja CPS)

The plain CamPro was supposed to have cam profile switching technology since the very first version, but it was dropped to save cost(?). As a result it had a big ugly torque dip at lower rpms (i.e. no power unless you rev high).

IAFM stands for Intake Air Fuel Module (lol @ i am fat man). I dont know how it works, but basically the torque dip is gone. No need to rev so high, easier to handle in city driving and traffic jams.

CPS is the real Cam Profile Switching technology, which also has the same effect as IAFM. Maybe a little bit more overall power. It comes together with something called VIM (Variable Intake Manifold) but usually it's shortened to CPS only.

Interesingly, if you try to read CamPro CPS in full (no short form) then it sounds like Cam Profile Cam Profile Switching. It should also be noted that none of these are cutting edge technology developed by proton. They exist in many other cars, probably under different names.

Sorry if i made any mistake in my post...cya

campro = no variable cam, no variable valve, no nothing

iafm = TVIS found on 1st gen 4AGE from AE86 from year 1985

cps = variable valve lift which dont work. a sophisticated and well designed engine with valve lift tech should make 165hp like B16A. this "new technology" could be found in 1988 EF9 CRX B16A

vim = variable inlet manifold

Thats why they doesn't mention Campro CPS, just CPS. Even the emblem at the boot also just CPS 1.6.

To be fair, the hp in CPS is low than the older VTEC engine, some are contributed by complying with Euro-4 standard (something about polution etc... ).

technology followed far from behind the century eh?

Whoops. I stand corrected, thanks.

from the 80s

What to do.. Even CPS they got from Lotus, if develop from scratch..

Maybe they want to drop the name 'Campro' becoz it already have bad reputation..

Then again, Gen-2 CPS engine block still says Campro CPS. I have photographic evidence.

Same with Waja, but Campro is not mention in car registration..

then what is in the registration?

campur?
o maCAMPRO ?
hehe

CPS 1.6 only.

btw, rebore the campro block and fit bigger bore piston to increase the displacement lor....
