Had to drive on CLUTCH....

Hello gurus,
I always had this confusion in my mind, the problem is that, i know its not a good habit to drive with ur foot on the clutch pedal, cos apart from the normal wear and tear, it also kills the FE.
But in a bumper to bumper traffic like in bangalore city am really finding it difficult, cos on a heavy traffic situation i just drive on clutch and break cos it gives good acceleration without any thorttle.
SO, my question is, is it good to do this practise, if not then pls advice on some alternative methods.

Regards

i am also confused about this.. but i guess in bumper to bumper traffic, u can't help but ride the clutch.. u can only minimize the clutch wear by completely flooring it and coasting with the brake.. ride the clutch to get some more momentum and then again floor the clutch and coast.. idea is to either completely engage the clutch.. or completely disengage.. and minimize the half-clutch duration.. i would be interested to know better ways to drive in crawling traffic.

I think there is a difference between exactly 'riding the clutch' and having to use it far too frequently and not completely engaging/ disengaging it while in traffic. People who literally ride the clutch have the left foot on the clutch pedal like a foot-rest even when cruising and when there is no imminent need to use the clutch.

For those who cant kick the 'riding the clutch' habit, I would think it would be useful to set the clutch to have some play and thus prevent wear and tear and/ or reduced mileage.

Try to release the clutch [completely engaged], but no throttle. FIRST Gear Only. You could get away with that a lot. That way you wont ride the clutch.

This will also allow you to accelerate well when required.

Agree with Condor. Just remember to full depress and fully release the clutch subjectively without accelerator input.

Is your car a diesel ? only a diesel will move that far without the throttle. Also a diesel is pretty easy to drive in the start stop city traffic. Just try to get to the lowest possible gear & release the clutch. i have also had this problem for a long while & rectified myself later.

Isn't that technically the same thing as your definition of riding the clutch but at a lower (idling) rpm?

My car stalls or vibrates (as if the engine is wants some revvs) if i dont put throttle in first gear and disengage only clutch. That is with ac on. Though it reverses without any problems with just clutch usage.

Its a wagonR by the way.

This is where an auto transmission is the absolute winner!

But without it.... depending on the gear ratios and idling speed (affected by the presence of any gradient of course), some cars will crawl forwards very nicely in first gear. My impression, so far of my Swift VDI is that it is going too fast as son as let out the clutch.

In theory, a good way to handle traffic like this is not to inch forward, but wait until you have a few yards ahead of you. Of course, in Chennai traffic (even in London traffic) this just doesn't get to happen. But if you are going up hill, with necessary hill starts then it does save clutch.

In a real crawl, ie less than walking speed, I'll just give the car a nudge forward and depress the clutch again...

I'd say that the definition of riding the clutch is holding the car stationary on an incline with sufficient acceleration by holding the clutch just at biting point.

I'd say that revving hard while moving the car slowly (like flood driving) is slipping the clutch

The habit of using the clutch as a footrest is bad as it is likely, even at small pressure, to cause very slight slippage. And I bet people who do this depress the clutch whenever they depress the break!

No, it is not the same as riding the clutch. it is just as theMAG said.

Riding the clutch is to always have the clutch pedal pressed, while in gear, and moving at faster speeds.

Riding the clutch is partial disengagement of clutch. A good explaination of Riding the clutch is given in Wiki - Riding the clutch - Wikipedia, the free encyclopedia

In a bumper to Bumper traffic it is recommended to engage gear 1 roll and come back to Nuetral if needed to stop. Do not ride the clutch. Riding the clutch reduces the effort for the driver but wears out the clutch.

in a really really crawling traffic (which is 25% of my commute).. there is zero tolerance to stall or jerk forward or u will get hit or hit someone.

flat roads (without incline):
it is just clutch and brake one foot on each.
if u don't have the momentum and there is not enough space in front, partially engage the clutch to pick up some momentum and depress it fully again..
if u have space engage clutch fully, rest ur foot on the floor and work the brake (best case scenario)
if u have the momentum and there is not enough space to suit ur 1st gear speed, depress clutch completely and work the brake.

if it is an uphill crawl.. use handbrake, clutch and accelerator. lot of people think this is a very sissy way driving, but the alternative is a sure way of ruining ur clutch.. most clutch plates have asbestos which is harmful to the environment :-)

if it is downhill crawl.. same as flat roads.. don't be tempted to switch off the engine and coast.. u will be shocked to find that the brake is very ineffective. always remember the handbrake :-)

OT: how come people don't use hand brakes in our movies, or keep their feet off the accelerator when the villain tampers the car brakes!

I think have a very bad habit of riding the clutch, both in the car and on my bike in heavy traffic situation. This has led to a juddering clutch (sometimes) on my bike (dont drive a car much). In the car, I have to make a conscious effort to move my foot away from the clutch, but I always leave it half depressed in heavy stop and go traffic. That way, if I need to move on, I move my right foot away from the brakes to the accelerator, and meanwhile, the clutch takes care of the "braking". Is it unhealthy to do so?
