Since ABS is an electronically programmed device attached to the braking system' date=' can it be done at an after-market fitment..??

Is it possible..??[/quote']

There are a lot of sensors involved as well. Even if possible (only as a retrofit in a car which has it in some models) I will advise against it. Unless done by a real expert tinkering with the safety systems is a big no-no.

@sgiitk sir:

Thank you for clearing my doubt.. I was in a perplexed situation as to why is ABS never retrofitted and also never heard of having such thing done.. I had asked many people, but all they say is that such a thing is not possible, never got any reason from anyone untill now..

The reason why I am more keen to know about the ABS thing is because I am looking forward to buy a car by early 2011..

In majority AT cars there is option for gear down and up' date=' which is operated by moving the gear lever to minus and plus sign respectively in drive mode...

He is talking of engine braking! In an AT car if the engine speed is lower than that corresponding to the road speed then the transmission is 'declutched' ie freewheels. In paddle shift cars if you go into the 'sports' or 'sequential' mode the reverse braking is activated. In a Honda Civic/City AT in S the fifth gear can only be selected manually, but that is a different matter.

@nishu :

Have you checked if the ventilation is open or not. Fuel vapours are very light and need slightest gap to enter.  (I mean large intermolecular space./ or is it ?). I think SG sir will be the best one to explain gas behaviours.

Myth or Fact ?

1. Do diesel engines have less running life than a petrol engine?

2. Releasing clutch early or releasing it slowly? Which is a better practice ?(People say releasing early is better as it provides efficiency)

3. A car without AC has more life than a car with AC? Is this true ?

That's the case I've experienced in my friend's Swift VDi.

Yes, It was having Windows closed, Air-Con On with Re-Circulation mode at that time, when I got the Diesel smell at the filling station.

 

Answers to your queries;

1) Yes, their Comfortable life is around 5-7 years, whereas a Good Quality Japaneese Petrol engine will even not show the l'll bit sign of Ageing in such time period.

Whereas Tata engines are having lesser life, max 4-5 years of Routine usage for both Petrols & Diesels or 1.5 lakh kms.

 

2) That depends on the Clutch adjustment & its Free-Play.

An Ideal practice is 'Release Clutch in such a way that the Passengers sitting Inside the car can't feel/notice that change or Gear Shift change.

 

3) Yes, usually AC & Hydraulic Power Steering units usually pose Unwanted strain to the Engine, especially in Small displacement engines.

It basically goes in' date=' the most common trick is a compressible accordion shaped hollow section. The idea is that if hits the chest of the driver it does not cause major injury. Earlier columns even 'harpooned' the driver.

Does this mean that there is a bellow like thing which acts as a spring on an impact? And in this process does the dashboard break due to the steering wheel going in?
