Q:I noticed how all the commuter trains here in Massachusetts use diesel engines. Will they switch to overhead lines in the not so distant future?

The diesel engine in a diesel-electric powered locomotive is barely used because of the fact the purpose potential for an electric powered generator which, needless to say, creates electrical energy that's then used to potential the locomotive's traction automobiles; gearing discovered/housed interior the truck assembly (the place the wheels are). So, genuinely, diesel-electrics (whether frequently talked approximately as merely diesels) are an electric powered locomotive that genuinely incorporates its very own potential plant on board. because of the fact the above poster reported, electrical energy is plenty greater efficient than merely utilising a diesel engine and generates plenty greater tractive attempt and known potential for a locomotive (case in point, overhead electric powered locomotives are the terrific form of purpose potential, wherein they actually artwork greater sturdy as tonnage/grades develop).

Q:If you obtained all of your energy from a diesel generator, how much diesel would you save per year by switching from incandescent to CFL? Diesel has an energy density of 36 MJ/L and your generator operates with 40% efficiency. Incandescent bulbs consume 60-100W, while CFL consumes 15-25W.

1 Kwh 3.6 MJ. If you use each light 4 hours per day, and each was 100 watts, that is 4 x 100 x 10 x 365 1,460,000 watt hours per year. That requires 1,460 x 3.6 MJ 5,256 MJ. / 0.4 efficiency 13,140 MJ. So you need 13,140 / 36MJ/L 365 Liters of diesel. If you used CFLs, at 25 watts, the answer is 1/4 of that, so 365 / 4 91.25 Liters of diesel. So the savings is 365 - 91.25 273.75 Liters savings. At $1.25 per liter, that is $324.19.

Q:first, no power plants here.there is a siege on my country.also no engines like these which generate electricity from wind.and they keep cutting the electricity.so, I`m ready to do everything with my hands.and well, yes I can buy some basic things. like dynamo.actually everything basic thing like diode and these stuff, I can buy.I have some prior knowledge in electricity,I`m 200% ready to study and know more,I`m 200% ready to do the needed machine with my own hands.so, can you suggest any basic Ideas that may help me? and already known Ideas that can be implemented

First question is can you get fuel like coal or gas? If something like that is possible you might want to look into either trying to build or buy a small gas generator or a steam piston that you could then use to generate electricity. Otherwise water, wind or solar is your best bet. Solar probably won't work to well unless you can afford to buy panels, making them isn't really an option. Look into wind, but hydro power especially wouldn't be that hard.

Q:a factory open 8.00 am to 4.00 pm and using 80kWh der day or 10000 w electricity in a given time it generate electricity by a diesel generator. is it possible to use a small diesel generator to generate enough power to run a motor and connect that motor to large power generator to generate whole electricity need for factory

A factory operating from 8 am to 4 pm uses 80kWh or 10000w of electricity per day generated by diesel. It is possible to use a small diesel generator to generate enough power to run a motor. If that motor is connected to a large power generator, it will generate enough electricity to power the entire factory.

Q:for electricity

Depends on the size of the generator, but it will be cheaper to use your wall outlet.

Q:272 hours (x 30mph estimate) @ 1800rpm's 8,220 miles. This is a stand by generator. Make Cummings, Model 4BT, Stamford 45kW generator.

ALL engines start to turn oil dirty as soon as they are started.regardless if it's a diesel or gas engine.

Q:I have a 3 phase 30k 60hz generator what would I need to do to use this to power my home ?

If the voltage is correct and you have access to the neutral the transfer switch is required by NEC. The electrical connections are neutral to the grounded conductor and one line to one leg and another line to the other leg with the 3rd phase isolated. Since the configuration of 3 phase generators may vary it is best to have a qualified professional electrician who has experience with them do the work. Some generators are Y configuration but others are a delta configuration with a tapped neutral. This will result in 1 high leg voltage which will damage electrical equipment. This size generator is best powered by diesel. Hope this helps. I repeat get an electrician who has worked on these units they are seldom a DIY for emergency power for a home most systems are single phase 120/240 volt 60 HZ in North America.

Q:I just purchased a miller big blue 400D diesel dc welder generator . I will be using 7018 rods. There are two controls on this unit, amps and volts, for best welding results, what is the best setting? I understand that metal thickness will change this this, but I' ll be starting on 1/4 plate. Any help will be appreciated.

practice!

Q:I am trying to find the value on a generator we’re trying to sell which is becoming a real headache since the thing was made in China. All I know about it is it was made by Shanghai Tractor and Internal Combustion Engine Corp and it’s a 20kw diesel generator. It’s about 5 years old but has only been used once since we purchased it. How would I go about finding the value for this generator? I need to have it sold as soon as possible.

Companies like China Star have become famous for diesel generators, so being from China is not a negative. Just look up any US made generator and reduce by about %30 to get value. I think a US generator of that size, which is sufficient for a whole house, should run about $2500. So as used slightly, I would start around $1800 I think. But you may have to come down to $1000 if the market happens to be slow. Check on Craigslist to compare. I am only guessing off the top of my head. It is contractors who buy them the most, and few people are building right now.

Q:If i am using a permanent magnet dc motor as generator then how should i calculate how much electricity the motor will produce ? or lets say i want to produce 1kw power with permanent magnet dc motor then how much hp motor i shd choose

I'm not an expert on this, but I'll give it my best guess. To try to point you in the right direction. First, you need to know the torque of this magnet. 1 horse power 0.74569 kilowatts So to get a 1 kilowatts, you need 1.35962 horsepower. The motor will have a certain efficiency. I do not know if this is factored in to the motors power rating, however if the efficiency is, say, 90%. Then you will need to divide the horse power by 0.9 to get the correct horse power rating. Is this a motor part of a diesel / fuel generator, or is it part of a wind turbine / water turbine?
