Stop Start Technology

[BundyBeej]

Wonder if the oil would have to get up to temp before this started, if you look at inner city driving and the amount you move sometime the oil would be stone cold and this cant be good for engine ware

Engines to be come 'consumable service items'?

Get to the 80,000km serivce in your BMW/Merc etc "Thank you sir/madam, that will be $45,000 for the service today, we have replaced your brake fluid, lubricated door hinges and replaced your engine."

Diesel E class had in Germany, you could turn it off

How do they do this for manuals too? Guess less and less cars are getting made/sold in manual these days. Manual = hoon

I think for the manuals it switches on as you depress the clutch.

so if you have the AC cranking and it's 35 degrees outside and you are parked, wonder if it turns the car back on to get the compressor making cold air and fans for the condensor etc...

It makes sense on a hybrid because at least when you touch the go peddle the leccy motor gets you going, then if you stomp it the motor will start. How annoying would it be stopped in traffic, lightly touch the accelerator to crawl forward 2m, and you have to wait a second for the motor to start....

How do they do this for manuals too? Guess less and less cars are getting made/sold in manual these days. Manual = hoon

in a manual with start stop, you have to have the box in neutral, clutch not operated, and doing 0kph. the engine will be dead. once you touch the clutch, it'll go again.


my bros citroen is an automatic (POS one at that) and it has an A (drive) and an E (economic) mode. you won't get any of the eco shit until you put it in e
needless to say it's not usually in E. cause it's a POS anyway that 's too slow to make the sunnies fall off teh dash, and needs about half an hour reaction time to decide this pedal to the floor means "i would like to vacate my current spot and quickly squeeze in that gap between those other cars at speed"

We have it in the nopics Madza CX5 (istop) seems ok freaks her out though. It has a button to turn it off, press go pedal or move the steering wheel and it starts.

My mum's Honda Insight does this, and while that is a hybrid it uses the combustion engine to primarily move around. Driving it, apart from the sound of it starting and stopping (which isn't really that noticeable since it's a relatively quiet car), you don't notice it. The thing that you *DO* notice is the AC, since when the combustion engine isn't running, the AC compressor isn't either. Fine when you aren't stop for long, but we found that if we had to stop for any longer than a couple of minutes, we'd get the engine running again (just lift off the brake pedal slightly) just to get the AC to come back on.

I suggest that shutting down engines while sitting still is vastly more important than 0.5 litres per hundred kays. It can be as much as infinitely better per hundred kays.

It's on all the new Subarus as well..

[baggins]

*skimmed...

You can manually override it anyway...

[Imposter Forg]

pffft my EA had this "feature" and it was from 1988.

My datsun used to shut down the engine when i stopped at lights.
And it was built at the start of the 70s. This technology must have been around for years!

yes, it does.. in my old bosses X3 anyway it did... I was quite impressed with it in his car, it was seamless, it deteceted him slightly lifting off the brake when you were on a hill and it started up striaght away...

I believe it also starts up when it realises the battery is getting low

I don't get it though, my Fiat 124 would shut down when i stopped at the lights, this isn't exactly new technology

Stop/Start operate on the brake pedal. Once you start to release the brake the engine restarts before you've even applied any throttle.

It's doesn't stop the engine if there is too much load on the electrical systems or the A/C is required. If the charge in the battery drops off the system disables itself.

So you can imagine during a hot summer that the stop/start system would never activate.

I beat you by like 20 seconds bro!
