Engine Start/Stop Vehicles

When both sides support something to me it means they both agree to go to the feeding trough together.

Just remember, no matter how cynical you get, you just can't keep up.

NADA!! said to be built for multiple starts built i call BS. everytime it stops + oil pressure drops so does the crank loose most oil film!!! unless it can be turned off leave it on the dealers lot!!!

Well....your wrong.

I think that's a nationwide problem, it's why there's always talk of an infrastructure bill which both sides support in theory. The gas tax here is 26.4 cents a gallon, it doesn't really add up to that much when you have to pay high union wages and have guys standing around the work site watching other guys work.

The cost of pot holes that knocking alignment out, damaging tires and wheels, etc. far out weighs the cost of repairing roads.

One should also know that in most states the gasoline tax is not solely for road infrastructure. We have dealt with that problem in WA state for years. It goes into the general fund.

I drove a friends new RAM a few weeks ago.... it doesn’t even have a traditional starter! The S/S was seamless .... it was beautiful. instead of a traditional starter, there’s this .... 16 (?) hp alternator/motor sitting atop the hemi with a massive drive belt. It was their mild hybrid tech and I’ll wager that at least mechanically it will be more reliable - no brushes, solenoid or gear train to wear. Perhaps there’s a backup starter hanging out if the hybrid pack is depleted, but I couldn’t find one. There was nil cab shake when it transitioned.

i read up on it after getting home and must admit, they did a fine job with it, incorporating it into the transmission shift strategy as well. They may have one of the best implementations to date.

That is the system mine has. I believe there is still a traditional starter for the cold starts.

That is how BMW is starting to do it with the 42V electrical system. Traditional starter for cold starts only, then the 42V alternator/motor for SS. Will also add brake regen and acceleration boost as well.

Have this on our 2018 Atlas. Got used to it and don't even think about it anymore. The systems/kit has been designed differently to accommodate the additional start/stop cycles (obviously). This tech has been around for a while now and I don't think I've ever read of pre-mature wear on parts due to it. I like the silence at stop lights. People resist change - this does take some getting used to and some slight changes in your behavior so it doesn't end up being annoying - namely more anticipation, learning the sensitivity of the brake pedal w/r to when it kicks in the start/stop system, etc. The only time I turn it off is occasionally in the summer b/c there are times where it will wait too long to kick the car back on to run the AC.

I wonder if anyone knows how much does that add to the cost of the BMW? How much does it add to a domestic car? Thanks.

Mazda's i-stop injects fuel and ignites it to restart.

What? Without a manual spark advance?

Thank goodness for computers.

The only time I had an engine that would stop then start with out my control was due to a bad ignition coil.

The old Malibu hybrid (2014ish) that pays the tax gets lower gas mpgs than the new regular gas Malibu that doesn’t pay the extra tax
the 1st year title plus registration can be an extra $400 as well.
... many hybrids don’t save $75 of fuel compared to the normal version of the car.
...

That's an example of the stupidity of taxing a particular technology or marketing term, vs. taxing actual results. It always results in inequities and unintended consequences.

I'm certainly not saving as much in local fuel tax by owning a hybrid vs. my previous car as S.C. charges as its hybrid penalty.

As a dealer tech I see a couple issues with these systems every month, either the start/stop switch failure, starter failure, or as the batteries start to age they will cause the car to not start when releasing the brake.

 

[Saabist]

I enjoy the feature.

As we used to say back in the day, different strokes for different folks. I would never buy a car with this "feature" but if you like it, enjoy!

I used to see that all the time at Acura. Never at BMW.

That must be a real hoot at a traffic light on a busy highway. Sunrise Highway on Long Island comes to mind. That I'll get some of the road raged loonies that drive that road into full swing.

so far I haven't seen failure to restart either, most complaints are about it not shutting down the engine every time...
