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 need a silent diesel generator of power capacity of 25 kW, i am going for the following brands(suggest something)1. Jackson Cummins2. Mahindra powerol3. Kirloskar

i have seen Kirloskar unit in an office complex. Seems to be good. No idea about the other two brands.

Q:I Live In Westchester NY, and ever since the Nuclear power plant in Japan went into meltdown I've been pretty worried about what would happen if Indian Point went into meltdown. Now Hurricane Irene is coming, Is it strong enough to cause a meltdown? Thanks in advance

No. A meltdown can happen when a reactor is not adequately cooled. At Indian Point, there are reserve diesel generators that are located 15 feet above the sea level. In the region, floods over 7 feet high never happened. At Fukushima, such generators were located low enough to be swamped by the tsunami. In case of simultaneous loss of its own power (reactor shutdown) and external power that may happen if high winds rip out the wires at the plant's switch yard, the coolant water can still be pumped through the reactor core. The pumps would be powered by diesel generators.

Q:i have a 7.5 onam diesel generator that runs for 15 min and shuts down i get a code 33 (overheating)I change coolant,cap and thermostat also checked air flow Still no luck.any ideas anyone

The onan fault code 33 is high engine coolant temperature fault

Q:i go to UTI get the diesel technican program were could i get a joband what would be the starting wageshow much would i make a yearthanksp.s i would eithier work in texas or california

If U learned a skill see which industry is needed for what u want to do.UTI should have jobs lined up.

Q:husband is looking for something that he can use for power that is more economical. (no natural gas lines)

Do you really mean as electric source and not as emergency back-up? Diesel would probably be the best choice for fuel economy/reliability. (Since it's not for roadway use, you can probably arrange to buy it untaxed.) For back-up power, you'd have to have a lot of long outages to recover the extra cost of the diesel engine set. For 'Prime power' - 24/7 , you're not going to beat electric utility energy rates even with diesel, as the required size generator for your peak loads will be idling most of the time. (Engine/generators are very fuel-inefficient at low loadings. - With a water-cooled unit, you can capture waste engine heat for house heat in winter though.) If by total electric' you mean heating as well, long term, you'd probably save on fuel if you had a smaller 'back-up' unit to carry the smaller home load when the heating system isn't required.

Q:HelloI am doing a question on my homework and im being asked to determine how long a tank of gas on a diesel generator would last a family if one tank produced 20kW of electricity. This family uses 2.052kWh of electricity every day. The problem i have run into is that i don't know how to determine how long tha tank can last with only those values, i have a feeling im missing something very obvious here. Any help would be great.Thanks!

You can't quite do this from first principals. The Gen-set manual may give a spec for fuel consumption, or for efficiency. More likely it does not. The solution is to fill the tank, run it on a dummy load or a real load, if you like, and see how long it takes to get to half way. Or some graduated point. I wouldn't run a diesel dry, as they tend to continue to run on their lubricant until they seize up. Much as I like to model and estimate things, I'm still an empiricist at heart. Jim Jarvis

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: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

The simple way to calculate the sizes of pulleys in you example is to use the following equation: RPMa*DaRPMb*Db Where: RPMa is the rpm of one end of the pulley system Da is the pulley diameter of the same end as RPMa RPMb is the rpm of the other end of the pulley system (opposite of RPMa) Db is the pulley diameter of the same end as RPMb In you case we have: RPMa3000 Da12 (we will use a starting point) RPMb1800 so: 3000 * 12 1800 * Db Db(3000*12)/180010 A 10 pulley should fit nicely on a 42 mm shaft so that should work as the pulley is much larger than the shaft.

Q:I have to wonder. WHY don't we have a car right now in 2010 that gets 100+ mpg?Ok we have the Honda Insight and Toyota Prius that get 50MPG+ WELL why not DOUBLE or TRIPLE or QUADRUPLE the Batteries and get 100MPG??? Seriously WHY NOT PACK Enough Lithium Ion batteries in there to get 300MPG?? You mean to tell me that with all the technology we have today in 2010 that we can't come up with a Hybrid that gets 100MPG??? PURE NonsenseSomeone somewhere is keeping the 100MPG car from being produced. Simple as that. You mean to tell me that you can't pack enough Lithium Ion batteries into a CAR to get 100MPG??? Yea right. You know it could be done. BIG OIL and other political forces DON'T WANT the 100MPG car. Why did gas prices go to $4.50 per gallon??? TO get the $$$ While the Getting was good. Now the gig is up and they know it.

Larger battery packs do not improve the fuel efficiency of a hybrid. The batteries are used as the electrical equivalent of springs. There are some important limitations on the number of miles per gallon any car can get in the real world. Climate control is a critical one - when energy has to go into keeping the passengers warm in the winter and cool in the summer it can't go into moving the car forward.
