Continuous Variable Transmission

hehe paiseh ar i blurred a while when i heard flooding.. was thinking something like river or so..

 

stupid brain ar haha

[Super7]

hehehe, you must be thinking how to do river crossing with manual gear

[En0203]

haha like that must get at least a 4WD..

 

sometimes i wonder how deep can those 4WD go..

quite deep, i saw those with air intake snorkel went as deep as almost windscreen level....

[En0203]

windscreen level!!! so deep ar?!?!

By far i think the best auto would still be the dry clutch system like what Alfa is using. Power is there and the reliability is ther. However, being a manual gear box, the car tends to roll backwards on a slope.

And also the Alfa's Selespeed is not so smooth, when in city (auto) mode, as compare to the normal Auto gearbox

you got my vote man

By sharing everyone learn and know more, making the driving community a better place.

that's what MCF is about

[Vtim]

where else? other than on the road, got in the sky meh???

uncle you ah! know still ask

Let's say there's flooding on the road and the water level is higher than your exhaust. In order to prevent water from entering the exhaust and into the engine, you'll have to rev the engine up so that there will be exhaust gases in the exhaust. What you do is disengage the clutch, rev the engine to 4000-5000 rpm, then slowly slip the clutch to move through the water slowly. So effectively, you're using the clutch to control the speed of the car. For auto cars, the only way is the step the brake and accelerator at the same time, using the brake to control the speed of the car. So manuals can be driven through floods easier compared to autos.

thanks for the tips

uncle, you drive car for so many years liao, you mean you don't know meh!

CVT was used only on smaller output engine. Its only recently that higher powered engine can use this technology.

 

Correct me if I am wrong, the EK3 Civic VTi was one of the highest output engine at 130bhp. The highest I think comes from the Audi A4 1.8T with CVT transmission.

 

Respond from the CVT is a bit slagging...cos there is a flat spot before the engine catch the transmission. But on the EK3...once on song...I think its rather responsive. It is smooth to drive and quite economical. (EK3 known to be able to hit 14km/L easily.) I think the CVT or as Honda like to call it...MMT...is a good match for the hyperactive power plant since its max power come in only at a heavenly 7,000rpm.

 

I tested the new Mitsu Lancer....quite noisy lor...since after revving pass 5,000rpm...no real power is avaliable....so the VTEC power plants suits the MMT cos it allows the engine to stay within the power band without dropping the revs too much like the conventional auto.

 

They have had problems with the gearbox before, but I think they have solved the problem liao cos my new box not giving me any problem. (am quite a hard driver...how hard depend on how "early" I wake up). But overall, 7,000rpm is a region that I frequent daily.

 

Given a choice.....manual please.

[Super7]

shhhhhhhhhh.... dun say so loud, wait everyone knows, i dunno where to hide my face .... bei di min lah..... (give abit of face lah)

 

i only knew must keep the rev high and use clutch to slow down the car nia.......by the time i started driving auto cars, sgp no more floods liao........... so din learn about the technique for auto car..........

you got my vote man

 

how can i not expect this vote from u

 

uncle, you drive car for so many years liao, you mean you don't know meh!

 

for me i know the manual tricks only (cos MY always flood one ), seriously i have no idea on the auto tricks, didn't know an auto can be driven this way, really good info for me

Guru you mentioned that "Let's say there's flooding on the road and the water level is higher than your exhaust. In order to prevent water from entering the exhaust and into the engine"

 

Does water enters the engine through the exhaust? I think water ingestion is through the intake and not thru exhaust leh. Engine is higher than water level, exhaust gas is pushing the water out as well..

[Lordgt]

bro, not everyone thinks the same way. Sometime share too much also kena suan until no end. That's why i only say what i need to say. Otherwise i shut up.

[En0203]

nvm lar, say what u think is rite lor, then kena suan liao will know that u are wrong mar, this is how learning process comes in mar

[Super7]

if the engine rev is not high enough, the exhaust pressure at the exhaust tip may not be strong enough to hold the water which is trying to get into the exhaust system.....

 

you forgot your phyisc lessons ahh???

Slight mistake on my part. The water will not directly enter into the engine. If water enters the exhaust, it means that exhaust gases cannot be removed from the car, and that will eventually stall the engine. I think this is a more sensible explanation for that matter. The revving up of the engine is to prevent water from entering the exhaust and subsequently stalling the engine.
