Q:Design the logic circuit for starting an emergency diesel generator. For the generator to start, the generator must be disconnected from the bus, there must be sufficient start air pressure, and the fuel tank must indicate there is oil. When these conditions are met, then the diesel may be started. Presume there are senors to determine these values.

This is just an and gate function. When the outputs of all the sensors are true and a start command is present, the output of the gate will go high to allow the engine to start.

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:Can anyone help me figure out where I can find a diesel motor that can be used in a motorcycle? Can I take the motor out of a diesel generator or should I buy a new/used one made specifically for a motorcycle?

diesel motors are not exactly meant for huge changes in load and very high revs typical of a motorcycle a diesel generator? those run in a very very narrow powerband go for the one made for a motorcycle if their are any unless you have a really good reason just get a 4 stroke

Q:Couldn't one say with certainty they are changing the environment in ignorance?

Sure. They're trying to warm the earth because it's really %@!ing cold down there.

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 what reasons are you in favor of using nuclear energy to generate electricity? For what reasons are you against nuclear power? consider the nuclear plant explosion in Japan.

I have to say I agree completely with Vladimier K

Q:I know that various types of locomotive's produce different amount of horse power. Here's the question: A single locomotive (any type) about what would be the average speed it could gain in 0 to 4 seconds on take off. Any smart A** answer will be reported for abuse, Thank you.

That's an interesting question. They vary so much, dont know if there is an average speed that would be of any relevance. I cant really improve on what has been said except to add a few comments. as you might have guessed acceleration, all you can possibly get is very important at times. Newer locomotives have taken most of the fun out of switching, too much computer controls. With the older ones, that is what made the difference between just an engineer and a hoghead. 8 throttle (all you got) full independent brakes, relaese the brakes and close the generator field switch all at once was about the quickest move, not sure the speed you would get in 4 seconds but it would be too fast for a switchman to get on. When I started on the Milwaukee in the early 70's, we still had the old electrics. If a switchman started getting cocky an engineer would make him a bet, he would say you stand right here at the front of the engine and i will take off, if you can catch the rear footboard I'll give you $10.00. With a light engine he couldnt do it, those things took off like a rocket, they didnt have to build up any amperage waiting for the deisel engine to rev , the full line voltage was immediatly available overhead. P.S., this has been very difficult for me not to be at least a tiny little bit of a smarta**, takes a lot of self control. LOL

Q:I read about it in an old Mother Earth news (1993?) The car was mainly powered by the gen. The batteries would only kick-in for hills, boost of power, etc. I am interested in this design, anyone know if it works well? Can I use a 480volt 3ph gen-set to power motor/Drive for more efficiency/power? I already know about the volt,prius,leaf.

On the web a few years ago, and this was ultimately sold on OKorder; was a Geo metro that was modified to run strictly on a 10 horsepower/7500 KW Lister clone/Listeroid Diesel engine imported from India. On a level surface, it could get to 55 Mph/88KPH if you did not mind the slow acceleration. Going up hill it would slow down considerably. They ran it with WVO and did better than 75 MPG. If you stick with a lightweight car, or light small pickup truck like a Chevy Luv, or similar vintage Mazda or Datsun, you could see reasonable results. You would have tradeoffs to consider as well, since batteries are heavy. Options to consider for your use- Aircraft starter generators for the drive motors. Diesel as your fuel for your genset. If you opt for one that has limited external monitoring circuitry, that will lighten the load some.

Q:I have never had any interest in cars until recently when diesel engines have started to feel like important and valuable power sources moving forward.

Q:I have 1500 kw load,i want install on Diesel Generator.What should be rating?

If its a pure resistive load consider the efficiency of the alternator, de-rating factors to ambient conditions etc. etc. After considering all of the above you need a 1650KVA (with 10% safety factor
