Engine Stop-start

[garlic]

Just bought a vehicle with this function. Do you guys enable this function or off it? Any issues with such frequent of off and restarting? How many years of using so far?

Thanks for feedback...

no head no tail, how to help you.

Orh... The engine stop-start function in a car, http://www.caranddriver.com/features/engine-stop-start-systems-explained-tech-dept , do you keep it on or turn it off while driving?

 

[tanwahtiu]

Singapore roads full of traffic lights, does it matters?

This feature is for country with 4 seasons, it says it is useful in winter? Best option is tell the manufacturer sell the car cheaper removing all gadgets meant to use in 4 seasons countries.

the type of gadgets needed in cars for SG weather is to suck out the heat inside the car or air con keep running to keep the inside cooler.

It matters as it saves fuel, but just concerned how it will affect wear and tear in the long-term since it is switching off and restarting the engine quite frequently..

This button is in place of the key to start the engine.
How would it be more frequently than using the key to start/stop?

The engine shut down whenever the car stop and restart when driver step on the gas pedal. The idea fuel be save when car stop at traffic lights and jams. Not really sure if it really save fuel. It just another device that will rosak as the car age. Only expensive conti cars come with this function.

The function is to stop and kill the engine when the vehicle stops (at a traffic light etc) when driver depress the brakes. The aircon, radio, headlights still powered on even though the engine is killed. I.E, your engine RPM is 0, thus no fuel is burnt and saves gas. Toyota has been using this on their prius since 1997. When your foot leaves the brake, even before stepping on accelerator, the engine restarts immediately and you can accelerate off, the process is seamless. The worry i have is about the durability issues and wanted to ask the experience of ppl here, whether turn off or on this function. This is not the engine start button.

Sounds like a hybrid car. Don't think the engine is power off, just at idling speed using the battery.

Nope, not a hybrid... engine si definitely killed off.. 0 rpm.. anyway here is a video about it..

This feature will definitely safe petrol. However, battery, starter and starting alternator life spans will be shortened. However, despite the higher maintenance cost, there should still be saving because petrol price is damn high now. The only concern is it increase the probability of the car failing to restart at a traffic junction. Personally I think it should be used only when caught in a massive jam. But then what about the air-con when the engine is off? It is ok in ang mo land where the weather is cool.

When engine is killed, the air conditioner is running on battery. When there is insufficient battery, engine re start again. I think there will be high wear on sparks, alternator, battery. In urban singapore, I find this a nuisance and not sure about the cost benefit vs petrol. For example, that 15% gain in petrol consumption may be offset by having tp replace batteries and sparks 20% faster. Never done the maths

The battery took over to power the car. OK, the model I used to drive doesn't have a RPM gauge so I am not sure when stop is 0 rpm or not. In place of the RPM gauge is a another gauge to show when the car is in battery/fuel mode.

The model is inside the list you posted so I am very sure it has the capability.

Let's do some quick estimates :

Let's say battery change is doubled, additional 10 changes in 10 years : $200x10 = $2000
Additional 1 change of stater and alternator in 10 years : $2000

Additional cost per year : $4000/10 = $400

That means saving from petrol need to be more than $400 per year to be worthwhile.

My petrol consumption is about $400 plus per month. Ya you are right. It is not worth it for all the hustle.

It's not the normal car battery and definitely not $200. Hybrid car batteries is in the thousands range. The one I am using will cost around $4000 for a replacement.

Fwah! Then you turn off the stop/start or leave it on... First 3 years have warranty mah..

During a promotion period to push the hybrid models, they even offer 10 warranty for the battery. Unfortunately, we miss the promotion. Fortunately, so far no problem.

I think for hybrid cars, the battery is already designed for this start stop feature so using the feature would not have too much effect on its life span.

Got money to buy car no $ to buy petrol meh! go and die lah!

When I drive the flying stature car (car no. SBD 6118, 5,600cc), I don't care about the consumption of petrol.

Just bought a vehicle with this function. Do you guys enable this function or off it? Any issues with such frequent of off and restarting? How many years of using so far?

Thanks for feedback...

test drove a merce E200 with this function, also when step on brake pedal at red light and let go brake still lock in place car won't roll even on slope and will release when accelerate again, seamless action.
I think people who buy this type of cars won't keep them long until problems show up.
