stop/start systems
Anyone seen this yet?
https://www.myninjaplease.com/green/?p=299 There is a similar system from Valeo that will be used in the upcoming Smart for example: https://www.valeo.com/automotive-supp...lang/en/pid/59 Wonder if you could retrofit that Bosch system in existing cars. 8 percent in the city doesn't seems pretty good. |

I think I saw the Valeo one. Aren't they testing with delivery trucks in the UK right now? The Bosch one sounds familiar too, because I think Valeo and Bosch have had working agreements, I would categorize this as one of the first "real" MPG performance mods that GasSavers have been craving. Why can't regular cars have stop/start systems retrofitted to them to save idle gas? It reminds me of a cleaner simpler version of this mild hybrid retrofit system : Electrocharger https://www.sigmaautomotive.com/elect...trocharger.php Quote:

Very cool. Now if only we could convince them to add a manual input to their controller. Any upcoming red, yellow, or stale green intersection is a candidate for a quick button-push and early engine kill. Adding an extra five, ten, fifteen seconds of coast-in to each such light could push that "up to eight percent" considerably higher.
Not to mention the potential of a dash switch for EOC P&G. :D Even without the manual input, it's nice to see things going in the right direction occasionally. Rick, who notes that Virginia motor vehicle law prohibits coasting "downhill" and on a "highway"... which implies it's technically legal in a city and on flats or uphill. (Well, until some hypermiler wins a case in court based on that and they change the wording to close the loophole. :p) |
I wonder how this system would effect overall engine life?

Good question. An electric oil and maybe water pump would be wise. Also, a modified starter motor that's in constant mesh with the flywheel ring gear would greatly reduce wear on both the pinion and ring gear teeth. Though a constant mesh starter would require either a clutch, or a brushless motor design to keep freewheeling drag to a minimum.

But once you go to a constant mesh brushless motor, you are half way to having a hybrid. That would just make too much sense.
|
I thought they use starter/generators, like a marine engine.
