my foot lah, first batch tak ada CVT cooler

first batch FLX has the problem with CVT clutch pump and fuel hose. Not all FLX is affected but still Proton make a recall on all FLX and replace the affected parts FOC.

Err..i dont get it bro..can u elaborate more, TQ

Sorry boss, i thought no cvt cooler
But still, proton shouldnt repeat that mistake anymore

im going to proton edar now! ehehehhe

but then they will have to up the rev limit, and reduce the reliabilty

if Proton repeat that same mistake, I guess all Exora Bold now will jerk like hell during pick up from stationary and rpm too low during idling which leads to potential engine stalling.

ya..the CFE + CVT is started from exora
if current exora no issue...thn am pretty sure this car won't have problem..cuz its the same setup

hard to explain in words cos power is not a direct measurement, it's measured figure derived from torque measurement of a rotating crankshaft.

a simple example


u see 2 curves, the torque curve doesnt peak at high rpm, while the power curve peaks at high rpm..

to get this curve, only torque (orange) is measured, power (blue) curve is derived from calculation of the torque x rpm

this ..

since i brought the curve out, easier to explain 1 step further.. if you look at max torque lets say at 4000rpm, the power is only 60-70% of the maximum power at 6000rpm..

so ideally with CVT, while you are at 4000rpm with normal gearbox trying to rev to 6000rpm, CVT will already allow you to stay at 6000rpm, making it 30% more power at that instant, that's why it's the most effective way to unlock all the power from your engine and will provide the best acceleration curve of the car..
of coz the downside is the dreaded rubberband effect, engine rev shoot up, while car barely moving.. so the behaviour of the CVT changing ratio software according to load conditions also need to come into play and need to be smart, so that people dun get buzzed out the ears when driving CVT car..

Err i dont know how u interpret my statement early becoz this is what i mean..power is dependent on torque and RPM
SOS

your source said this, which i already said. rpm is measured, torque is measured. power is calculated or derived from those 2. i already said it above. dun understand any further need to do engineering course..

Added on February 15, 2012, 10:19 pmoh forgot, earlier discussion, i mention let torque be 200nm and power increase to 150bhp right? that's different situation cos there is turbo element mah.. you can control the boost which affects torque and power.

thats why previously i said u cant separate those power and torque for rotating shaft..they are dependent btw, i'm already a mechanical eng. n done the ICE course TQ

all I know is, this new car (the Premium spec one), just have to pijak to 2,000-4,000 rpm then air will be feed into the turbocharger, witchcraft happens then the car goes faster.

plus they have torque base control loop system thus aim for flat torque for certain rev band

why cannot seperate the 2 condition, both condition is at different rpm wot.
i said set the conditon at mid range rpm, boost until 200nm, while power at high rpm can increase to 150bhp, obviously by boosting the torque at that high rpm..

i didn't say 200nm at 150bhp at 6000rpm

Added on February 15, 2012, 10:30 pmu have a point about reliability but then if a turbo 1.6L doing 150bhp should not be really stressful cos for other brand of turbo engines mah not even 100bhp per litre.. if not reliable then have to redesign the engine lor..

Skoda can top that... Nice one though.

I don't like keyless entry. Too easy to steal a car that way. Thieves are just not smart enough, yet.

@jetpacker: Oi, don't bash the Octavia. I like that one. It looks serious.

MR_alien: In Europe no one wants auto. Many models don't even offer an auto version, because no one would buy them (especially in cheap cars). There is a small shift towards auto started by DSG, but other than that... And yes, not wanting to drive an auto includes girls. There are many who prefer manual. At least over there

I prefer manual in traffic jams. Makes the ride smoother. Just starting uphill I agree, there auto is nice.

Government ban people talking on the phone, in KL I've seen a public bus driver happily chatting along while driving the bus! I have seen so many drive with a phone next to their ear, they might as well make it legal.

The airbag off feature is required by EuroNCAP, and probably also other NCAP rating systems.

@CooShyRee: Perhaps these people aren't used to cars with airbags?

Hopefully there is something warning the driver that the passenger airbag is off. Like the car actually saying it every time you start. Or a light on the dashboard. etc.

so proton have a new slogan?
honda = VTEC kickin' in yo
proton = CFE kickin in yo

back to this CFE engine..their aim is torque thats why the feedback loop base on their torque..back to basic, why u need more power since in the end u need to burn more gas for it since u got same torque in the end..conservation of energy power is work or energy in the given time.

in europe..u dn't even need auto
cuz cars there are much more competitive
why auto when u can have DSG

there u go guys..like i said be4..its required, proton wouldn't just put a switch there for nothing
since proton say this is their 1st international car
thn the features has to meet international safety standard
