can a weed eater engine (2cycle) turn a car alternator and charge a 12vdc battery?

hector596 questioned:

can that size of engine yield ample rpm (if collectively to a car alternator) to payment my 12 volts dc battery ?

Why not build a car like this?

RobRob questioned:

Place in a very small and efficient diesel or gas engine, that just recharges the battery, and have the car run completely off an gripping motor. This would demand a more powerful gripping motor, of say, 100hp equivalent, may maybe be more tho if de rigueur or to suit the American market.

This would save a lot of consequence by having a smaller engine and boost efficiency by having the small engine running constantly at its most efficient rpm, just providing ample potential to meet the average potential requirement of the car. (Running down the battery a bit below heavy driving and charging it up below set alight driving. The gas/diesel engine may maybe be as small as say 50hp but much more potential would be unfilled if looked-for.

Place it in a very aerodyamic car like a Prius. Make it a plug in hybrid too so you can payment it at home as well. May maybe make it possible to run off E85 or biodiesel as well, but wouldnt be elemental.

This would indeed be much more efficient than even something like a diesel smartcar, which gets 88 (imperial) mpg collective, without the drawbacks on size and potential. And we have hybrids, we have gripping cars and we have cars that run on e85/biodiesel already so its not like the equipment isnt unfilled.
Johnnie – Gripping motors are very efficient really – typically around 90% compared to 40% for diesel and 25% for gas. The battery may maybe be a similar consequence to the one in the Prius and that isnt too heavy.
James – how would it be more pricey than a Prius, they have a generous battery and gas engine too.
Vicky – here are. For model the Tesla roadster has an gripping motor equivalent to around 240bhp, and a generous ample battery to potential it for 250 miles per payment.
Richard – the Prius is really very open surrounded by as it only has a small engine which doesnt take up as much interval. A small generator would take up even less interval. I’d be pleased to travel across America in a Prius (even if it’d be a lot simpler to glide in actuality).
Also richard, excellent aerodyamics would boost the efficiency, making the car closer, use less fuel, and probably quieter at high speed.
Lazyeddie – Americans buy the Prius so this would cater to the same market.
trainboy – i dont see how this would be much heavier than a Prius.
snapdrag – until the array of gripping vehicles increases, along with places to payment them, and the time it takes to payment them, they will only really be matter-of-fact as a second car for the city. By having a secondary fuel source you take out these drawbacks and have a car thats matter-of-fact for a lot more public.
Wolf – The Chevy Volt looks like a excellent top but i cant be with you why it looked-for a 1.4L 71hp engine just to potential the generator. Indeed something around a third of the size would have been more efficient, less pricey, lighter and smaller.

Also, why is it only a 4 seater?? Indeed a 5th seat would boost sales a lot at effectively no superfluous cost? And i cant see why one wouldn’t fit, its the same size as a BMW 3-run.
John – how much potential does a car of the Volt’s size need to sustain an average speed of 70mph on the freeway.

I’ve obsessed a car which only had 54bhp at 70mph and it was doing around 3500rpm. Compelling into account cars only yield their peak potential at nearly the maximum rpm, it must have been using less than 54bhp, ill take a guess at 30bhp. Yes, it was a smaller a car, but i skepticism the Volt wants more than dual the potential to cruise at the same speed.
John – e85 is subdue better than gasoline for the background. Something like 35% less co2 i reflect i read.
And infer E100 was used to yield E100. Out of each 5 gallons bent, 4 would be used to make it, and 1 would be sold. But it would subdue be carbon neutral.
Observably here isnt ample interval in the planet to yield ample for all our cars, and subdue have ample interval for all our food. But as long as its use is kept to a small percentage of the market, its subdue excellent for the background.
Also John, according to wolf below, you only need 20hp
edub – no you wouldnt be better off having the engine potential the car. Why do you reflect a Prius gets better mileage than a Yaris for model, even with the Yaris life lighter.
The engine performing arts as a generator would be able to run at a continuous optimum efficiency eg. 1800rpm, powering the car it would not.
Nata – You gain efficiency as a smaller, more efficient engine can be used, which is able to run at a continuous maximum efficiency.

It will by all accounts cost $30,000.

The prius isn’t that small. In the UK, where I live, its vaguely privileged than average size, and in Japan theres lots of cars much smaller, that seat 5.

The prius can go 100 mph, its top speed is 106. You’d lose your licence if you went 100 anyway.

The prius gets less MPG than an M3 when its life thrashed round a footstep. No one drives like that on the road, and irs not the same as cruising at 70mph.

A generous percentage of the Prius’ sales have been in the US. The Prius is the largest promotion hybrid worldwide.

Why would it need to be widened to seat 5? I’ve been in much narrower cars that seat 5.

How do i wire my second hand alternator to charge a car battery direct?

furrmunk questioned:

I am now effective on an project making a fill up veer that turnes a car alternator then charges a 12v dc battery but i need help on the wiring supervise over to to battery to payment it. I have two wires from the alternator which are the clear and i take it the body of the alternator is the earth so can somone tell me how it must be wired to payment the battery and where must i atatch my multimeter to test it. i must have ample rpm to get 13 to 14 v

how to calculate the dimensions of an interior permanent magnet motor given it’s torque speed profile?

Sidewinder questioned:

Hi I’m a mechanical engineering adjust apprentice effective in the area of hybrid gripping vehicles. My information in gripping apparatus isn’t very excellent, as I’ve only recently ongoing compelling courses on them. We are tiresome to top a hybrid car in our academe and we have been able to calculate the optimum torque-speed profile for the vehicle but want to know how huge and heavy it would be to see if it would fit by the book in our car. Even if you grant correlations that give approximate answers, it would be fine, even if we would like privileged suitability. The torque speed profile looks like this – the peak torque T1 is obtained from 0 rpm to N1 rpm where the torque is continuous and potential increases. Form N1 rpm to the max. rpm the torque decreases in inverse family member to speed providing continuous potential. My question – are here correlation unfilled to calculate motor dimensions and consequence from T1, N1 and max rpm?

How much time to charge a car battery with an alternator?

khaldooni questioned:

If i run an alternator (run of the mill sedan car) with an gripping DC motor to payment a car battery (12V – 50amps), what is the best motor do i need (RPM, torque, hp, etc..) and how much time to payment the battery (High and mighty that the battery is dead unfilled)

Thankfulness

Why bikers decrease the Ideal Speed of a bike?

Linda Jones… questioned:

My brother (CBZ Extreem ATFT, Hero Honda, 150cc) fall the Ideal Speed (Which is normally 1400 rpm +- 100) to 1000 rpm to boost the millage and fuel efficiency. Is it really boost millage and boost fuel efficiency?

can u put alternators behind each tire rim 2 generate electricity to run an electric car or hybrid efficient?

Timothy H questioned:

i was thought that here may maybe be a hybrid that may maybe use alternators emotionally caught up in the rear the tires to genorate and store(in superfluous batteries) electricity that may maybe be used to run an gripping motor. the only problem i can reflect of is that the alternators would add consequence or more resistance which would make the gripping or gas engine work harder. i know that u would yield “free” energy when coasting, but i’m not sure that it would be ample to even make a difference due to the low rpm. i don’t know if anyone else has thought about this or is effective on it. if unknown had tried already, i would try to build a small prototype out of a rc car to try it out. i’d need help even if in view of the fact that i don’t know too much about electricity or any of that material.

engine: which rpm for highest efficiency?

JohnyD questioned:

I want to adopt a driving stylishness that minimizes the fuel consumption. I read that at a continuous speed you must handbook in as low rpms as possible. But when you pull up, I read you shouldn’t pull up too slow. Then again, high fuel consumption is frequently caused by pulling up quick…

What is the pledge then? My engine reaches its peak productivity potential @ 4000 rpm. Is this the peak efficiency level / lowest fuel consumption when pulling up?

How many kilometers can I make on a Dodge Magnum RT?

Mr. Magnum questioned:

Ciao, I plot to hold a 2006 get out of Magnum RT sometime next month.
I only handbook in the city, and I’m wondering how many kilometers can I make on a Magnum RT; maintenance in mind that I only do city driving.
Also, what is the best way to keep up the best fuel efficiency, what driving problem must I adopt? Maintenance it below 3,000 RPM when accelerating?
Delight help, be grateful you.

Does Anybody Have Experience With The Nitro Box Performance Chips Sold On eBay?

bonkers4baseball questioned:

I was looking at Niutro Box normal chips on eBay and I was wondering if they really work and are safe to use on my ‘98 Camaro? They “Look excellent” that they will not yield any chat in reliability or longevity, just more horsepower and torque throughout the entire RPM array plus better fuel efficiency. Is that really right or is it just a scam? Delight respond promptly, I need to know ASAP. Be grateful You!

What gear to use in manual transmission to maximize fuel efficiency at 40mph?

freeze_sr questioned:

I handbook an ancient Mitsubishi Lancer. 5 speed manual, carburetter engine 1300cc, 77hp@6000RPM and 109NM torque@4000RPM. Curb consequence @ 2024 lbs.

My question is, if I’m roving at 40mph, would it consume less fuel in 4th gear or 5th gear? In 4th gear the RPM is about 2300 and in 5th its about 2000RPM.

I used to take upon yourself it was best to cruise at the lowest possible RPM but friends have said that at 40mph, 5th gear may consume more fuel than 4th gear.

So which is better?

Why does volumetric efficiency rise with engine speed rpm?

male geek questioned:

This is for full throttle!

for those who don’t already know ‘volumetric efficiency is a ratio (or percentage) of what number of fuel and air really enters the cylinder all owing to induction to the real room of the cylinder below static conditions.’

Indeed at idle the air has more time to enter the cylinders as the valves go slower charitable a hight efficency. Then at privileged speeds the valves open much more promptly importance less air can get in the cylinder?

Fuel efficiency with a standard car?

katiebear152 questioned:

My boyfriend drives a ordinary and Im tiresome to gather in view of the fact that when we buy our next car this summer I want to get a ordinary. I told one of our friends this and he questioned why so I said it s cheaper to keep up and more fuel efficient and also expenditure less when you buy a ordinary car very than an automatic, he said its not as fuel efficient in view of the fact that its privileged rpm in view of the fact that you batter gears which uses more gas…

Is that right? We’re inane to buy a ordinary any way yield my boyfriend likes them more, but I was just wondering if he really knows what he’s discussion about.

ok i ride at 90-102 rpms all the time now just thinking a cars engine fuel efficiency gose down after 60mph is?

Davd C questioned:

here a rpm on a bike where your body is no longer efficiency any more

how do you maximize fuel efficiency in a manual transmission car?

epic_laydown questioned:

must you handbook at the peak gear possible with the lowest RPM’s or does it matter? must you not accelerate excessively? Thankfulness.

Is there any ideal rpm at whcih motor bike engines are supposed to run so that the fuel efficiency is maximum?

iamtrying questioned:

If yes, what is it?
And, is it uncommon for each bike?

How many RPM should i be driving for the best fuel efficiency?

2007 Ford Escape Hybrid Battery Problem?

J B questioned:

I have obsessed 6600 miles in my new ford escape hybrid that i have owned in view of the fact that january. In the last week, even now when the ride out was fantastic, i have not had the hv battery go in at all even on long trips, life idle, or inane 5mph. Two weeks ago my battery was always kicking in and i got 37 mpg all the way. Why all of a sudden is my battery not effective?
im not using any climate hegemony, and i havent been driving any differently. Even when im inane 5mph the engine is at 1000 rpm
