Idling engines chap my ass. But TINSTAAFL. ~~Auto stop is terrible for engines; the majority of engine wear in passenger automobiles occurs at startup. Also, during auto stop, the catalytic converter cools down a bit, so emissions go up. More wear —> more emissions —> more waste.~~
Edit: For my rebuttal, I started digging into this. While the sources I found are still "auto technician says so," it looks like engines with auto-stop are built for more start-stop cycles. I was operating on outdated information. Automobile engines were/are typically designed for 100k to 150k starts. In trying to find more information about auto-stop, the overall consensus seems that auto-stop engines are designed for >300k starts. Moreover, there seem to be some accounts indicating that exhaust temperature is part of the auto-stop monitoring, which would make sense and keep the emissions controls running properly.
So, thanks to @borkborkbork, @0ops, and @Janx for prompting me to get updated information.
But as a bike commuter, auto stop was pleasant in traffic, at least until everyone suddenly started up again and then stomped on the pedal.
The wholesale gutting of all attempts at environmental protection is an interesting choice for the "protect the children" party. But even as an avid car hater, ~~I'm not sure this is a huge loss.~~
Cold startup. Oil temps don't instantly drop the second the engine shuts off. The only real additional wear is on the starter, flywheel, and battery, but then every auto start system I've heard of is overbuilt specifically to deal with that.
The car's not emitting at all when it's stopped. Any emissions prevented by idling to keep the cat hot are dwarfed by what was emited to...do nothing except keep the cat hot. It's like spending $5 to save $1.
Look buddy I don't even like auto-stop and my car's too old to have it anyway, but this is misinformation
you had me at overbuilt. Since thats the system that like to die I would be psyched at a vehicle having it hardened.
Source? Modern engines have special bearings and oil systems to put up with ASS systems. Emissions do not go up, otherwise it would have been killed by CAFE long ago.
this would be true for a pre-2000 car. systems designed for it not so much.
Any reputable sources for your claims? My understanding is that vehicles that have auto start-stop are designed differently. It's vastly different from turning off your vehicle without the feature at every stoplight.
The starter motors are better, and the oils are thinner now in all vehicles, but there is still more wear in start stop vehicles than In the same ones where it’s been disabled.
