Q:i mean from off state to ON State,the amount of diesel it reqiures to burn out.

Very little. Less than it takes to run at power while underway. The fuel lines are only so big, and it can't flow fuel any faster than that. There is a myth that machines take a LOT of energy to start up. Some people say it takes as much power to start your PC as it does to run it for 30 minutes. The same is often said of fluorescent lights. That is not true - it is essentially never true. It is used as an excuse to avoid shutting the thing down. Why can't they? Because the pipe or wire supplying the fuel/energy is only so big. If a PC took that much energy to start up, it would trip the circuit breaker. The energy also would have to go somewhere, and energy always goes away as heat. A massive surge of startup energy would be a massive surge of heat, which usually burns or explodes a thing. So no -- devices generally do NOT use massively more energy to start up than they do to stay running. Some times might have a startup surge of double, or perhaps triple - such as a hard drive or compressor spinning up. But nothing more than that, and only for an instant - too fast for most circuit breakers to trip.

Q:can DG's be used as a backup for single phase and three phase ac?

Of course diesel-fueled engine generators can be used a backup, i.e. standby or emergency power. They can also be used as prime power (on all the time). If you need to supply a single phase load, either use a single phase generator (only available for small loads), or use a larger three-phase generator and make sure it has a Y-grounded connection. Even better, get an electrician or electrical engineer to choose the right device for your system.

Q:I will put this generator to power my automated vehicle which have sensors, servo for the steering, motor for the rotation of the rear shaft, laptop for camera vision etc.

A battery powered wheel chair has everything you need. You can buy an old one cheap and fix it up to work as your automated vehicle. Use Lithium Ion batteries for maximum power or one of the new AGM car batteries that provide deep discharge operation.

Q:I have a 3 bedroom / 1 bath home. It is just 2 of us in the house. Also, I've heard that there is way to plug your generator into any wall outlet and it will charge your whole house. Any truth to this?

Plugging a generator into an ordinary wall outlet limits you 15-20 amps of single phase power, or less than 2000-2500w. And it would only energize one leg, or about half the circuits in your house. You'd also want to throw your main breakers to prevent you from backfeeding the neighborhood and/or electrocuting a lineman. Overall, it's not a safe or efficient way to connect a generator. You want a generator plugin that will safely allow more power to fed into your house along with a transfer switch that will properly isolate your house from the grid whenever you want to connect a generator. As for sizing, you need to figure out what you really need vs. what you have, and for how long. For most storm-related outages, you can probably get by with a relatively small amount of power (refrigerator, a few lights, etc) for the few hours or at most 1-2 days that power will likely be out. If you want to cover longer outages or you have higher level of necessities, then you'll need a larger generator. Also, you need to worry about a fuel supply especially if you're planning for a long outage. Fuel transportation and storage can both be problematic, although the problems vary by fuel type (gasoline, diesel, natural gas or propane).

Q:i have an old marine onan generator. It is a two cylinder diesel engine and the block is almost round on the bottom. I thought it was a cummins but im not sure. I know it is vague but can anyone help.

Cummins okorder

Q:Does anyone currently live off grid?If so, what type of alternate power system(s) are you using?Solar? ---(I think very expensive and in this part of the country, not enough sun.)Hydro-electric? ---(may be a viable choice if I have enough current running through my stream and or enough head from a waterfall)Wind? --- (If It is installed high enough and does not obscure.)Diesel Generator---(may be ok if underground, low speed, water cooled)We are planning to build a log home in up-state Pa. as a second home for now, but our primary residence in a few years.Thanks in advance for your answers!Newt

i don't know about your possibilities where you are but i would definitely suggest using as much natural lighting as possible and the alternate wood heating furnaces available

Q:Example 1:A GP38-2 has a 2000 HP prime mover diesel engine.What are the horsepower ratings of the electric motors geared to the axle? [4 electric motors; 1 on each axle how much HP?]Example 2:An SD38-2 has a 2000 HP prime mover diesel engine.What are the horsepower ratings of the electric motors geared to the axle? [6 electric motors; 1 on each axle how much HP?]I know the tractive effort of the SD unit would be higher, but with 2 more motors on the axles, does it have more horsepower also?

The short answer is, the horsepower is fixed. That is determined by the diesel engine and that can't make more power, it is just divided either by 4 or 6. A 3000 HP GP 40 locomotive pulls considerably more amperage than a 3000 HP SD 40, same horsepower divided by fewer axles, which is of course why the 6 axle pulls so much better at extended low speeds than 4 axles. The total horsepower stays the same, at full throttle the prime mover cant make anymore, your GP-38 will not be able to make any more power than an SD-38, both 2000. Added: At full throttle the main generator is putting out all the power it can, there can be no more load on it, that is fixed, the variable is the number of axles. Avio's figure of 750 HP per axle is absolutely correct, But those 750 HP motors in a 3000 HP locomotive obviously are never making over 500 HP each, there isnt enough power available from the main generator. That is why those motors last so much longer and are able to pull heavier loads, they are never making their maximum power. The amps we see on our meter in a locomotive dash is measured at the number 1 traction motor, not the generator/alternator output. At 10 MPH under maximum throttle a 3000 HP SD-40 (6 axles) pulls around 900 to 1000 amps (per axle), at the same speed a 3000 HP GP-40 (4 axles) locomotive is pulling well over 1200, heat buildup is a factor, short time ratings are soon exceeded and wheel slip is uncontrollable. Good question.

Q:A diesel-powered generator with a cost of $145,000 and estimated residual value of $7,000 is expected to have a useful operating life of 75,000 hours. During July, the generator was operated 150 hours. Determine the depreciation for the month.

145,000 - 7000 132,000 / 75000 1.76 per hour July 150 hours x 1.76 per hour rate $264 Keep in mind I rounded the $1.76 but if you follow this procedure it will get you where you want to be. I hope this helps and wish you all the best. good luck

Q:I live on an island and we only have one power company they have taken our power away from us and because we were stealing power from them and would have to pay a hefty fee which we decided not to pay. we are running on a diesel generator right now but i was wondering if natural gas or propane generators are cheaper and or more efficient. ive checked the gas suppliers website for prices but it wasnt very helpfull.I would need a generator that is about 15 kW

If you have a natural gas pipeline then that's what I would use. Nat gas burns the cleanest, no soot, no mess, no fuel filters to clean, the motor oil lasts longer, no tanks to get water and gunk in. no fuel stabilizers needed, no fuel spills and no tank certifications, etc. With a pipeline you won't have to go shag and store fuel and you won't run out. Even in a wide spread power failure the nat gas is usually not affected. If you have to lease or rent a nat gas tank THEY have to certify it against leaks.

Q:(sorry for my English) i don't know anything about electricity generation but i ask this with a curiosity ok. 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 so we can save diesel and money possible or not

A perpetual motion machine is one that makes more power than is used to run/rotate it. In your case you want a small engine to run a large generator. But the power of a large generator is only a portion of the energy going into it - there are losses due to friction, electromagnetic heating, and resistance losses in the wiring. There is, in fact, a rule of thermodynamics, that no process is loss free, much less producing extra power. Much more complex schemes than yours have been proposed (and cheated investors) since powered mechanical devices were invented. The best we can do is make devices more efficient to lose less power.
