Q:I have put together a 4 cylinder peugeot diesel and an 8 kw alternator.At first it was direct coupled to run at 1500 rpm but didn't have enough grunt when i struck an arc with my mig welder. I then put in a lay shaft the engine runs at 2275rpm alternator at 1500rpm. same problem engine allmost stalls under heavy load. At this speed the engine is producing max torque 70 lb ft the alt should only need 33 lb ft. pls help

The alt is what RPM you will set the engine atMost 120-240 volt are 50 HRX and run at 1800or 3600 so if it's the 3600 back end your using the wrong engineUnless you use a pulley and belt to get the correct RPMMY 8K Diesel marine ONAN direct drive 3cyc runs at 1800 Rpm If your over loading the genset than no engine will workwhat is the load your pulling as 8K is 80 amps Max single 240V or 40 amp double 120V

Q:Effects on health, economy, business, the environment, etc.

heating of the planet through global warming, but it is less refined than regular, so that saves a little energy.

Q:I know that when a coil is moved between magnets, it produces electricity. how does a generator work without magnets ?one more thing I want to know, what makes the generator turn on when the light go out ?

Generators all use magnets of one form or another either permanent magnets, or electromagnets.

Q:For a new observatory in the Andes at 17,000 feet, we need to provide power continuously for 4 months. Requirement is 208VAC, 3 phase, 10 kW. The site is accessible by large truck, but connecting to the power grid is out of the question. We are thinking diesel generators and large fuel tanks. Any suggestions out there? Thanks.

Are there any issues with the high altitude? You may need to modify the generators to work that high. 17,000 feet is really up there! Have you considered fuel cells? Wind power may also be an innovative solution.

Q:I want to build a deisel generator that electrolizes water to make oxygen and hydrogen to increase fuel efficiency. Then I want to make an algae bioreactor and extract the fuel from the algae to power my diesel generator. What is the smallest engine that can support this? Do I need fuel injection or can the oxyhydrogen come in through the air intake? As I understand with oxyhydrogen added you can acquire a 100% fuel efficiency.

Q:ANDwhat kind is it? How many times have you had to use it? How many things could you run on it? How much did you spend? Would you buy one with more power next time, or is the one you have sufficient? What types of problems have you had with running it. Do your neighbors always ask to hook up to it?

If you have access to natural gas the best would be a unit that uses it as fuel. Advantages include - reliability, no refueling, automatic periodic testing, low noise, compact size, built-in weatherized cabinet. Disadvantage is cost. One must really think long and hard about installing a generator vs its cost/hassle. How many outages have you had in the last few years? how long have they lasted? how much inconvenience did you/would you experience? do you live in a winter area where you require heat? Do you have friends/family on the other side of town where you could seek refuge for a few days? I have lived in many areas of the world (including Florida)and never have felt the need for a generator. A refrigerator will hold food for about 12 hours - its freezer will hold food for days if unopened. If you do opt for a generator, I would size it to handle everything EXCEPT the air conditioner.

Q:and diesel generator and ATS that switches between two electrical sources ??

There may be no difference. It will depend on the application. For example, if I specified an ATS that had the proper voltage and current capacities, the only other item of concern would be to determine if the transfer would be a make before break or a break before make type of transfer. In a make before break, it would mean the sources would be placed into parallel operating condition before one of the sources was interrupted. This would require the ability to synchronize the sources. Which means the frequency, voltage and phase relationship of the sources must match before they are placed into parallel service. On a break before make switch, usually only phase rotation and approximate voltage levels are of concern. Hope this helps, Newton1Law

Q:I live in an area where storms are quite common, in fact the storm season approaches us. We have thunderstorms during which our lights start flickering. I am scared that one day light's would go out and we'd be left in the dark, to be safe, I want to build a small generator electric. I am not talking about toy generators or stuff like that. I want a small generator, one that I can use to charge cell phone (if dead) or power up the radio. Nothing too big either, mind you, I am not an engineer, I am a biologist, so I don't get all the connection stuff and such. So please go easy on the engineering lingo.

Since you are nor an engineer, I think you'd better bought that generator. From you need, I guess something with capacity of 1000-2000 watts is enough. Things you need to consider: Quiet or noisy one (of course the quiet one is more expensive) Fuel (gasoline, diesel, or LPG)

Q:I want to be able to plug my APC Smart-UPS RT 8000VA 208V into a diesel generator when our power will be down for an extended period of time. The max OUTPUT of the APC unit is 6400w. Does that mean I need at least a 6400w Generator?

yes, plus extra for loses and to charge the battery. I'd get a 10kW unit, at least. But that is a lot of power, do you actually use all of that, or is the UPS oversized? In that case you can reduce the size of the generator. .

Q:What will be the effect of ambient temperature on diesel generators

The specific understanding of the price of the unit should know the basic information about the brand, configuration, power, etc..
