Fiat 500 at CES 2008  (Source: DailyTech/Brandon Hill)
Bosch Start-Stop system reduces fuel consumption and emissions by 8%

Reducing emissions and improving fuel economy is a huge area of investment for many carmakers. Most people equate this type of technology with hybrid or electric vehicles, but Bosch has a system that helps improve fuel economy and reduce emissions on diesel and gasoline motors as well.

The system is called the Bosch Stop-Start System. Bosch and Fiat announced recently that the Fiat 500 would use the systems and Bosch went so far as to claim that 50% of European vehicles would have the Stop-Start system by 2012.

Bosch has been making the system since 2007 and reports it has already delivered 500,000 of the special starters to BMW and Mini. In the Fiat 500, Bosch says the Stop-Start system would be available with the Dualogic automated manual transmission and the 1.2-liter engine. Fiat does say it plans to install the system on other vehicles as early as 2009.

The Fiat 500 will also use a Bosch engine control unit including Bosch software that analyzes the sensor data to start and stop the engine of the vehicle. Stefan Asenkerschbaumer, president of Bosch Starter Motors and Generators division said, "In 2008, roughly five percent of all new vehicles in Europe are equipped with a start/stop system. By 2012, we estimate this will be every second newly registered vehicle—most of them with Bosch technology."

The Bosch Stop-Start system works by turning the motor of the vehicle off when the vehicle is stationary. An example is if a driver pulled up to a stop light, the Stop-Start system would turn the motor off while at rest. When the driver put a foot on the clutch pedal to put the car back in gear, the engine would start back up.

Bosch says that the system reduces fuel consumption and CO2 emissions in the urban component of the New European Driving Cycle (NEDC) by up to 8%. To ensure that the starter lasts with the significantly increased stop/start cycles, critical components of the special starter have been strengthened. Bosch says it increased the service life of starters used in the Stop-Start system compared to a normal starter. The bearings in the new starter were strengthened, the commutator is strengthened, and the planetary gear was improved as well.

The system has other components including control software, a battery sensor, crankshaft sensor, and sensors at the pedals. A high-efficiency alternator and a deep-cycle electric battery are part of the system.

A few specifics on the system remain unclear. For instance, presumably the system won’t function if the driver doesn't place the vehicle in neutral. Bosch isn't specific on that aspect of the system. Another concern is how long the vehicle will be able to remain with the engine cut off in high power usage scenarios like summer with the air conditioner running or in winter with the heater on.

Bosch doesn’t specify if the system would automatically restart the vehicle if it were still stationary if the battery started to get too low on power. Presumably, the system would restart so the driver won’t be left with a dead battery.

Well with Barrack in charge we can look forward to that too in the upcoming years.

If the Democrats impoverish you through higher taxes, the republicans will do with tax cuts funded by deficits.

Until the Republicans return to the mantra of smaller government and fiscal responsibility, they are both poor choices.

Bush might have made the government larger, sure. But Democrats make governments far more INVASIVE. And thats a fact.

And tax cuts hurts us how exactly ??

I find it funny that the same people who refuse to believe " trickle down " is even possible, firmly cling to the belief that somehow wealth can trickle UP.

But Obama says so, and we can't very well argue with the Second Coming now can we ?

ya know... its been four years and libs are still complaining about Bush, saying he stole the election. I don't think it has to do with being Republican or Democrat that one is a sore loser.

The difference being, democrats complained about something that already happened, republicans are complaining about something before it happens...

Give Obama a chance to govern before making negative statements such as reclaimer's...

If the most powerful country in the world can give a former coke addict a chance, I think Obama deserves one.

That website is nothing but a Obama propaganda machine.

The state of Hawaii has SEALED his birth certificate. Obama has not requested, or provided, his birth certificate. And ONLY Obama can request it. And the state said he hasn't. So where is that website getting a copy ?

And why in the hell did his own grandmother say, on record, that he was born at the Coast Provincial hospital, in Kenya ?

Nice photoshop job by the website, but I think YOU lose.

The dirty little secret about tax cuts is that nobody actually cuts taxes. A tax " cut ", in government terms, simply means a halt in the INCREASE in taxes. Because politicians, after all, believe all of your money is theirs anyway.

When Bush's freeze on tax increases expires, which it will because Obama certainly won't renew them, I hope people like you change their tune.

Trickle down economics has been proven to be an utter failure - it doesn't work, period, and there's no sound logical reason why it would either.

The idea that rich people are going to spontaneoulsy hire people just because they can afford to is idiotic. They hire people because they have WORK that needs to be done, which is created by DEMAND.
What creates demand? Consumers with money that can afford those products.

Trickle-up economics is the radical notion that if you give someone poor $500, they're going to spend it - all of it, and the money eventually makes its way into the hands of the rich people that make the products that poor person is going to be buying.

Trickle-down economics is the notion that if you give a rich person $500, maybe, just maybe, if you're really lucky - they'll give it to someone poorer, for no apparent reason.

Let's put it this way: Under McCain, he would have given the $1000 dollars I'd get to someone like Bill Gates.
Great, so Bill Gates would get $1000. Maybe somehow, just somehow, I would benefit from him being richer.

On the other hand, under Obama I'll now have $1000 (Thanks "Lower-taxes-for-the-middle-class"!).
What can I do with a $1000? Maybe I'll buy a new PC. Hrm, now how would Bill Gates benefit from that? Oh, gee, maybe it's because I'm buying software from him.

The difference is under Obama, my money is going to Dell, Intel, Nvidia, Seagate, Microsoft, etc, etc, etc and it's going to keeping the people working there having a job.
Under McCain's plan, you're just relying on the hope that Bill Gates is going to kindly give that money to the less fortunate.

Trickle-down economics is voodoo economics for the uneducated;
Trickle-up economics has been proven to work.

Riiiight. Only the best economies we have had. Thats no proof though, right.

... sigh.

The person is STILL poor though. You haven't done anything. So lets say you GIVE 30 million poor people $500 bucks. Then what ? What have you done ? And who's money did you take to give them the $500 ?

You CANNOT make poor people rich by making rich people poor. Thats just idiotic economics. How is that going to work ?

quote:

WRONG. You are not not not not not not not NOT NOOOOT GIVING him $500 bucks. You are allowing him to KEEP $500 more of his OWN money that he has already earned !

NO ! Again, NO. Trickle down isn't about rich or poor. Its not about GIVING poor people anything. Why are you so hung up on the idea that the rich MUST be tied in to the "poor" ?

Ha ! No, you wont. Its amazing people like you actually believe this.

When ?? Under the Carter and Johnson administrations, where " trickle up " was in full play, we had the WORSE economies in our nations history.
