Stop-Start Systems

[Blueray]

Many people really don't like this function?

 

I want to install also don't have.

 

My personal opinion : start stop systems are overrated. better off without it. 

[Thaiyotakamli]

How about removing the fuse for the start stop system?

No need to remove anything. Just use programming to code it.

 

If you remove the fuse u might not be able to start the car. The start stop system is initiated by the computer itself. So need to work on with coding

Maybe those with this feature can share their experience during the causeway jam that lasted 2 hours with ac running? It will be interesting to know if the temp can be maintained or need to push the car hahaha

[Lala81]

U must be driving a merc lol

 

If bmw turn on circulation everytime start the car but wont auto turn off

 

 

Stupid merc, the technician even said to me cos its good to bring in fresh air inside ur car. I said of course la german air so clean no problem one. Try intake the haze here lol

 

It's pretty darn stupid. Lol ...

stupid germans haha

I asked the PA workshop to disable mine permanently but they say cannot due to LTA regulation. They do the memory coding trick for me. So it always remember the last setting, that is turn the damn thing off.

 

But the internal circulation, cannot. After some time, it will allow fresh air in. Stuck in the causeway, some exhaust fumes enter the cabin.

It will wear the starter motor pre mature as for driving condition is Singapore . There is a button in the Vezel to disable it everytime you start the car before moving off.

1.  It has some smarts in that if it detects you are in a traffic jam, after the first restart and you continue to creep, it will switch off the start/stop till you have at least driven continuously for a while or distance. 

 

2. It monitors the internal temperature and if it falls a certain percentage over the set temperature, it will also disable the start/stop till the internal temperature if reached.

 

3. Some brands have a option where you can set that the aircon does not go into blower mode when the auto start/stop is active. I believe volvo goes into blower mode while some like bmw and some Japanese brands still allows the aircon to run at full blast.

 

4. Most auto start/stop system has a external temperature monitor where if it exceeds will cut off the auto start/stop till the temperature drops. Some can be as low as 30 degrees while others can be as high as 35 which will mean it works better in singapore.

 

Current technology means that the manufacturer with auto start/stop will already have specs in bigger starter motor/batteries which will be able to take the millions additional starts/stop over the life of the motor. They also have special coatings on the pistons/shafts for models with start/stop to ensure that the potential "additional wear" during startup is minimised or will not impact the lifespan of the motor etc. 

 

Whether all these measures will mean the same motor/starter/battery lifetime over a car with auto start/stop is up for debate. But auto start/stop has been in cars for nearly 8 years now I believe.  Almost all of the cars in Japan has been on Auto start Stop since 2010 and almost no ones switches it off.  Just walking in Tokyo and you can see all of the cars at a traffic light is on auto start/stop. 

 

I still do not like auto Start/Stop on my car.   :-p

So it does stop activation if it is too frequent. That is very important.

 

As to the design to take extra start / stop, I am sure thr bigger battery and better starter to withstand additional frictions will take care of it.

 

Thr biggest challenge here which is different from temperate countries is air con. I dont think any battery they fit I will take care of the air con.

My dad Toyota also has such function. If fully depress the brake, start/stop will kick in. alternative just press the button to disable it. Very stupid system, once stop, it depends on cooling coil which will not last a minute as compressor not working to supply refrigerant. And engine cranks up again.

Battery and starter motor will up lorry soon, due to short driving distance(insufficient battery charging) and high wear and tear on starter motor. Might as well auto wind down all window instead.

Manufacturers say start-stop is good for drivers as can save petrol. In actual fact it is good for them cos it help to reduce their emissions and easier for them to pass the regulation without spending money on extra R&D in other areas.

 

Also manufacturers want to pass the buck to someone else. It may save emissions for them, but how about the extra environment damage due to more car batteries used? That is no longer their taiji, let the battery company go settle.

Precisely.

 

If cars have idle stop, there will be less exhaust fumes around.

 

Looks like not a lot of people here have tried being stuck in a motorcycle jam in the causeway. The fumes may make my life shorter by a couple of years.

my stop/start function sucks.....

 

1. cannot last a red light stop. engine will start halfway.

2. steering is locked when stop/start function is in effect.....stop to reverse, steering is locked so have to deactivate function. reach home cannot straighten steering wheel unless function is deactivated.

 

so i like to drive with the function deactivated. car has been like that from day one.

 

ps. my internal circulation stays on all the time.

Read somewhere that engine brake means wear and tear on engine and gearbox whereas brake brake means wear on brake.

 

The author said cheaper to repair/replace brake than engine/transmission, and so he rather use brake brake unless in situations where you need engine brake - e.g. for downhill where brakes will get too hot and ineffective if brake too long, or for more effective cornering to go in and out the curve faster at high speeds. 

 

Don't know how true is above.

Any engineers can answer?

 

 

 

Better to take B.M.W (Bus, MRT, walk) - then zero wear/tear on your GB, brake pad, chair, leather, rubber, tyre whatever.

 

Oops... maybe knee will wear out first.

Then green light

 

U depress the pedal

 

 

Theres 1-2 sec delay in moving off as need to start engine (auto brake activated)

Well mine is a Mazda 6 and I have been driving with the start stop function for the past 1.5 years. Initially took some getting used to but now I'm fine with it.

 

Given all the concerns about the environment, surely less emission is good, no? Besides, why burn petrol when you don't need to?

i totally agree with you.

The car has few area of monitoring

 

1. If the set temp increase from set temp i.e 23 degree to s4 degree, the engine will kick in and then will shut off once the temp stays constants at 23 again

 

2. If the batt level falls below 12.8volts, the Start stop trending will not trigger again till the charge is up to 13.4 

 

3. If the alternator charging shows signs of batt degradation, it will capture a soft fault and will be kept in the car data log and start stop will not kick in till the fault is cleared or when the charging resume back to steady state.

 

during my 1 hr 45 mins jam, the car behave as usual with aircon and start stop occasionally kicking in which is far better then manually switching off the car and rolling down the window

Thanks, explains alot.

 

A friend of mine with the same car told me his start stop ceased functioning during a bad causeway jam. It only reactivated a couple of days later!. When my battery was failing the start stop ceased as well, until I replaced the battery.

 

Strangely, it seems it doesn't work when the hood lever is released too. I found this out last week when I accidentally released the hood and drove around for a day without noticing!
