Q:I just purchased a KOHLER generator 500 KVA would it be safe to run at 10 % load for 6-8 hours

500 kva is a big generator and I am guessing it is diesel. It is safe to run at 10% load however it is not good for the engine itself to make a practice of that. It can lead to lower cylinder temperatures and incomplete combustion over time. It is always better to run at or as close to max load as you can.

Q:I have two steel jerry cans that i used to carry gasoline in, now I want to store diesel fuel for an emergency generator in them. after I empty them will residual gasoline contaminate the diesel beyond usefulness?

Diesel Gas Can

Q:I know I take for granted that I have indoor plumbing but where does the water pressure that causes water to flow come from when I turn on my sink? Is it a pump. Where does the energy come from?

The water drains out of the sink because it is a downhill flow from the sink to the sewerage outlet. The actual pressure is due to the height of the water and gravity. This can be stated as a head, in meters. Similarly the water comes out of a tap because it has a downhill flow from the supply reservoir typically. This can be a tank on a hill, or a tower. The water is transferred to the reservoir from its source like a lake by a pump, which gets it uphill to the reservoir. The pump is usually an electric one, though a diesel generator could be used as backup, or even a diesel driven pump could be used. Electricity is cheaper to run, considering the energy involved can be costly. The static pressure comes from the height of the reservoir above the tap outlet. This is also seen as a head. The typical pressure is 40 to 80 psi (equivalent to 30 to 60m of head or water column). Once the water is flowing at full bore the pressure drops, due to the pipe resistance and such effects, typically represented as 10-20psi approx. 8 to 16m of head. This is the pressure before the water leaves the tap (faucet), and is enough to flow through some device like a shower. At a remote property a tank stand may be used to get some height, or a pressure pump, which is equivalent. With a pressure pump the water is pumped into a rubber bladder like a large football bladder, so it can be squeezed out on demand. The pump runs cyclically as required to keep sufficient pressure in the bladder. This arrangement is known as an accumulator. High buildings may have related accumulators or a reservoir on top, and a pump/s to get water up there.

Q:I'm estimating 81 mpg at best, and 47 mpg at worst.

How big a car, carrying what, on what roads, in what traffic? Far too many variables to compute.

Q:i have 45 kva Perkins diesel generator cranks, battery is ok,does anybody know why the engine doesn't start?every think looks clear!!!please help!!!

Diesel cranks but doesn't start. All that's left is the fuel system. Is there a pre-heat unit? Is it working? Pressure at the injectors?

Q:I need to run a fridge on a small power generator that don't have enough staring power to run it , would adding a huge industrial capacitor make it possible ?

The old style, pre- electronic wash machines used that same principle. They had a relatively small motor and used one or two huge capacitor's to get the motor going. Those capacitor's save up the maximum amplitude on the voltage sine wave (120V) and bleed out the power when the amplitude reverses each 1/60 th of a second. You might luck out, but I'm not sure if the AC compressor motor is an induction motor like the wash machine motors are so check out how to wire the capacitor in the circuit first and if it works with a compressor motor. It should, come to think of it, a lot of compressor's have capacitor starts s I can't see why a refrigerator compressor would be much different. You did say the running wattage of the generator is enough to keep the fridge going.right?

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

Carbon. And it's normal.

Q:I am leaving a career as an aviation electrician after 23 years and have applied for a job as a diesel locomotive electrician with Union Pacific. I was notified about a skills test and was hoping to brush up a bit before the test. Which areas should I focus on studying? Also what can I expect on a day to day basis working in this field? And lastly, although I can troubleshoot and wire a jumbo liner in my sleep I don't have specific experience with large generators and motors. How will this affect me in the hiring process. Thanks in advance for any help.

Q:I have a 1992 Toyota Tercel that sits in my yard. It ran at one time, but has been driven so little that it now no longer starts. Had this problem one time before and paid someone to fix it. They replace the fuel pump to get it started again. Other issues are lost title, back left tire seems locked, and busted windshield.I hate to just trash this car and wonder how difficult would it be to turn the motor into a backup power generator for my house? Is it feasible? One of our sister companies at work has a diesel engine that acts as a backup power for their computer room, so I wondered if I could possible do the same for my home.Any suggestions?

Almost anything is possible if you spend enough time and effort on it. The real question is: Is it worth it? What you have is a crappy motor in a junk car. Take it out of the car remove the transmission. Attach the engine to a motor mount like an I beam box frame that you have fabricated. Attach a generator unit to the end of it. Then you need to fabricate a speed governor of some type to keep the engine running at 1800 rpm to generate 60cycle power. Lets not forget your crappy high mileage engine. It might work for a while but after all of this effort you will probably wish that you rebuilt it. OR You can just buy an 8KW generator for $2000 JUNK THE CAR.

Q:I just want to know why Oahu is vulnerable to black outs

You know, it not that bad, so not sure why you say they vulnerable to black outs, sure we have some, but not that often, ok? Here the thing, all electric power on island generated by diesel generators, and some time they break down, and infroastructure very suseptible to dampness, so when it rain, like rite now, we gonna get some power outages, but I neva see a true black out where all power out in city, that kinda thing, ok? Maybe they happen when I asleep, ok? Peace and aloha
