Wow, you're a genius!! Thanks for stating the obvious! Maybe you missed my other post about other BETTER ways to save those extra two drops of fuel a year. (you can't post some shit that I've already stated that I know, and then act like I don't know it...that's why you get flamed)Quote:

Bad driving habits. Are you going to hold classes teaching people to ease onto the accelerator instead of mashing it stoplight to stoplight?
As far as saving millions of barrels of oil a year?
That's why I've been asking you guys to calculate fuel loss due to alternator drag. What most here are forgetting is very important. Gas/diesel engines are inefficient. Factors such as torque and horsepower help make them that way. What torque and horsepower lose in energy efficiency, they make up for on the back end when spinning something so minute as an alternator.
For example, my trucks engine has a lot of torque at an idle. That torque and power, however inefficient, will be there whether a tiny amount of drag is being placed on the engine from an alternator or not. The inefficiency of the mechanical motor is made up for running an alternator in this regard.
So my point is, having a powerful engine is in itself inefficient. That's how it came from the factory. You have to remember that certain types of engines aren't going to be effected by such a small factor.
Now, when you have one of your little horsepower fuel saving engines, then yes, the engine will have to adjust, because the mechanical power of the engine is so little.
Therefor, driving a small, underpowered "green friendly" car actually wastes more gas for using DRLs, than say, my ungreen friendly truck. ;)
The solution to all of this isn't trying to find ways to conserve fuel. The solution is to develop electric battery technology to make electric cars conveniently applicable to everyday life. Produce the electric from nuclear power plants, and we're done with this bullshit.
Good page. I think most alternators are 55 amps if I remember correctly.Quote:

My truck, has 325 hp and 610 torque. I'm guessing the alternator on my truck is bigger than 55 amps....not sure exactly. BUT, running every electric accessory on it at full speed, The horsepower loss from the alternator still wouldn't even be 1%. Like I said. Negligible, marginal at best, and a ridiculous argument.
edit-also, remember the DRLs will be using a fractional percentage of the 1% energy usage stated above. ;)
Your question is ridiculous and you know it. It isn't even relavent.Quote:

You don't seem to understand that headlights will use some amount of gas proportional to the amount of power they draw, regardless of the engine. your truck uses the same amount of gas to run the headlights as a headlight equipped go cart.Quote:

It wastes the exact same amount of gas. It uses a smaller portion of the gas it uses on the headlights, yes, but that is fucking retarded.Quote:

I think the REAL benefit of DRLs is that if they are always on, people won't forget to turn on their headlights at dawn/dusk when they might matter. So why not have the lights turn on or off based on a sensor, like a lot of cars already do? Then they don't run during the actual day, but are still on when needed and might be forgotten.
How many times do I have to tell you that using electric devices DOES use gas, it's just so minuscule it's barely worth mentioning?Quote:

What you're failing to grasp is that a vehicles engine isn't based around the alternator, and that is where you're wrong.
Do you think a Geo Metro pulling a 10,000 lb trailer is getting the same fuel mileage as my truck pulling a 10,000 lb trailer? That's proof that different engines are designed to pull different loads, whether the minuscule "draw" of an alternator, or a 10,000 lb trailer.
Efficiency of the system and inertia contributes to how much fuel is being used. Whether it is negligible is really a matter of opinion. Personally I haul ass in my truck with the windows down, the lights on, and the stereo up. I don't really give a fuck about a little bit of extra gas.
Some people do. Hypermilers are the extreme end. Some of them get ridiculous mpgs from normal cars. They prolly get flipped off a lot also.
Blurred, I must have misread your first posts. I really thought you said that there was no load on the engine from the lights.
Anyway here is a good page with more fuel saving tips:

I like this one:Quote:
Turn off the lights
24. Well, this one might be a safety concern. Many Rental Car companies have daylights enabled on their cars which are rather efficient. However every electrical equipment is powered from the alternator which will increase its load on the engine to produce more power. So when you can do it safely, turn off those headlights.
Fair enough.Quote:

Tundra CrewMax. Truck hauls ass with a 5.7l V8.
And I got the big mirrors. Maybe I should get those replaced to save some mileage.
A famous barista recently noted that a cop's mag light/club uses fewer D batteries than blurred's ghetto blaster.
Maybe you could do your part to reduce CO2, just quit breathing. Do us all a favor.Quote:

I am sick of the government always telling us they need to put new expensive shit into cars and making it mandatory. Let the market decide, and I'd like to see a lightweight sports car made without abs, without power windows, locks, DRL, Traction control, blah blah blah, just light and fast and cheap. Cars are heavier than they have ever been, and much of it is due to government mandating all kinds of shit be put on vehicles. Enough already. For what it is worth I realize removing DRL from a car isn't gonna do squat, but it's the principle.
why oh why did you do this? :DQuote:

I can't believe that people from the US argue against DRL's due to the increase in fuel consumption. The irony is overwhelming.
Mine come on up here in the land of maple syrup & molsons but south of the 49th ... its a government conspiracyQuote:
