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:For hydropower how much MWh can be generated with same capacity plant?. (Because plant never run for 24 hours of the day we need a factor to calculate above value)

there are about 2000 ,working hours a year on 40 hour work week. I would guess about 200000

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?

I have a Generac 5500XL generator. It's been used on several occasions, the longest being 3 days after Hurricane Juan blew through Nova Scotia in September 2003.

Q:Have a diesel engine that puts out average 3000 RPM and max's out at 3600 RPM I want to belt drive to a generator head that only needs 1800 RPM to operate at 60 hertz what size pulley should I use. Also for further info the shaft on diesel engine is 1 inch and the generator shaft is 42 millimeters

If the engine is likely to be running for a long time, fuel consumption is likely to be important. You want to find out at what RPM the engine produces maximum torque.(If it's a car engine that will likely be related to the cruising speed of the car in top gear) All IC engines are most fuel efficient at the rpm for peak torque. If the engine can make enough power for your requirements at the rpm for peak torque, that's the rpm you should aim to run the engine at. Will depend on the engine of course, but peak torque is usually around about 1/3 of the rev range, I estimate that to be aprox 1800rpm [ie (3600-800)*1/3 +800 ] If aiming for 1800rpm for the generator, with an engine speed of 1800rpm, you don't need to change the rpm at all. That means the pulley's can be the same size, unless the belts slip (flat/ribbed belts slip aprox 3%- probably not enough for you to worry about) So that's the ratio sorted out. Physical size of pulley. All belts have a minimum diameter pulley which they can go around, so long as the pulley is larger there's no problem. Minimum size pulley depends on the thickness, and construction of the belt- and that depends on the power you're transferring via the belt. If you give some indication of the power you're wanting to transfer I'm, sure you get some additional help you'll probably need a governor for the engine to generate at 60Hz give or take a bit. Many diesel engines just have a max/min governor relying on the user to governing the rpm under varying load . You'll need fairly good control for electrically generation, but it needs be nothing much than releasing the throttle a little if the generator is running fast, and if the generator is running slow pressing the throttle. Hope that helps

Q:I want to run the generator just enough to feedback enough kilowatts to make my annual bill zero usage.

Power and gas companies also charge you a monthly fee for the meter on your house.

Q:Hi. We're off grid and therefore installing a 3 phase Diesel generator. Each phase is rated at 20 Amps continuous(23 Amps max). we want to run 3 Split type ACs, one on each phase, plus some other small appliances.Our problem is that each AC has a start up current of 20 Amps, which will trip the safety circuit on the generator everytime it comes on.The ACs running current is only 8 Amps, but jumps to 20 Amps for a split second everytime the Compressor comes on.Is there a simple way to control the start up current on the ACs? I read something about putting a coil of wire on the input of the Compressor. I tried that with a water pump just to check if it works. The surge current was still there.Any ideas if I can use a Capacitor? If yes, can you tell me what capacity I should use? If you give me the formula I can figure it myself. We run on 220-240 Volts, 50 HZ.Thanks for your answers.

Is it too late to switch to a 240 volt single phase generator of the same capacity? This would have a 60 amp capability and would handle the surges with no trouble. I don't see how a capacitor will help. If you are stuck with the 3 phase generator, perhaps you can switch the ACs for ones with 3 phase motors. That will spread the surge over the 3 phases. There are also soft-start ACs .

Q:I have been given a cheap diesel generator made from china. It starts alright, but seems to be reving very high and poping and spitting until it has ran for a while. It surges some times as well. I don't really like it much and haven't used it to power anything other then to load test it a bit. I have checked the motor and all it has is a simple governor on it with no adjustments? I am not sure even where to start adjusting anything on this. Any body have one of these and same problem? Please I was given it, I would like to get a little service out of it , not just junk it Fuel, oil, air filter are all new.so? help?

So what did you want to do with this engine? It sounds like a stationary engine used to power a generator or pump or similar application at a constant RPM.

Q:Diesel generator selection criteria?

into the network at the same time the provisions of quality certification testing of diesel generator to implement the communication rules

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?

Q:Hi,I read an article and it said This implies, that more or less all customers of Esson, who own appliances dependent on permanent electricity supply, dispose of their own emergency Diesel-generator installed on their premises.I try to understand it, but I think it is grammartically wrong. I think it should be This implies that more or less all customer of Esson, whose own appliances depend on

This not so much grammar as style and choice of words, but anyway here goes: This implies that all (or almost) all of the Esson customs who require an uninterrupted power supply for their appliances use emergency Diesel generators to insure this. You don't have to add to insure this, but it sounds better. Please note that several of the words you had in the original dont have the right meanings or sound unnatural, which is why I changed them. F.ex., in English 'to dispose' means to 'get rid of, to remove, to throw away, to sell', where you mean the opposite, 'to have'!!!
