As per topic...thanks...

Was a CVT btw?Originally posted by sidestep1984:As per topic...thanks...

Have you actually tried to do a search on the internet in the first place???Originally posted by sidestep1984:As per topic...thanks... -
put it in Cars forum...make it a one stop info place arh...makes it more interesting for tech noobs to read....its not for my benefit....its for everyone who is curious...Originally posted by dansplace:Have you actually tried to do a search on the internet in the first place??? -
CVT: continous variable transmission.
like it's name suggests, it's a kind of transmission which continously varies the gear ratio, via means of a belt n pully system. -
Hence the engine change remains at the optimum, instead of dropping with every shift as in an ordinary autobox. However it's more suited to smaller engines and it the uninitiated, it sounds like a slipping clutch.
Cars that have one include the Fiat Punto, Audi A4, Nissan Sunny and the old Civic MMT. -
yea man.. kind of weird driving a cvt for first few times.. floored the accelerator.. the rpm goes up... stays at 6k rpm while the car accelerates. very much like a slipping clutch indeed.. at first i tot someting wrong with the tranny.. seems sluggish.. nt till i realised it was a cvt auto

CVT = Continuous Variable Transmission
What it does? Change gears lor ... whoa lau .... -
haha..
my mum driving 1..
i can tell u...dont bother.. -
I guess the car does not jerk when there is a change of gears.

how does it reach a decision to vary gear ratio continously?...does it somehow remember driver attributes?...Originally posted by HENG@:CVT: continous variable transmission.

It doesn't work that way. The pulleys are conical in shape and the chain moves up and down, enabling the engine speed to be kept constant.
The engine speed is pre-determined usually for efficiency, and when sport mode is engaged or the throttle is floored, it changes to the speed where maximum power is delivered. -
no lah..Originally posted by johncooper:dun tell me your mom driving the Colt Plus Turbo ...
it's a RB26DETT tied to a CVT -
woooops...nvm...found it...hehhehe...was abt to ask a dumb question

Add's SGD$2500 to your car's price tag. Silver engrave comes complimentary on the trunk.

in theory, they decide where the max torque n bhp is, and allow the ratios to change so that while speed increases, rpm remains constant. the ECU does the controlling.Originally posted by sidestep1984:how does it reach a decision to vary gear ratio continously?...does it somehow remember driver attributes?... -
hmmm i dun tink nissan sunny is using CVT...althou it states at the back CVTC but its different cos u still feel the jerk when changing of gearOriginally posted by Kuali Baba:Hence the engine change remains at the optimum, instead of dropping with every shift as in an ordinary autobox.

Hm... i tot nissan CVTC is the enginee technology, just like the honda vtec and toyota vvti....
nissian i think got what E-throttle thingy...Originally posted by quek:hmmm i dun tink nissan sunny is using CVT...althou it states at the back CVTC but its different cos u still feel the jerk when changing of gear -
E-throttle is acclerator without the cable but relies on electronical signalOriginally posted by CarDreamer:Hm... i tot nissan CVTC is the enginee technology, just like the honda vtec and toyota vvti....
