Q:has anyone ever heard of a 50cc diesel engine? if so, where could i get one and how much is it?also, i just want the engine, i dont want the rest of the scooter, bike, etc.

diesel motorcycle engines were made for the military. They are about 700 cc's and very expensive and rare. 50cc diesels were never made.

Q:Did some searching, and found little other than single, model specific, manuals (either paper or on CD). The paper manuals are $50-60 each. Single model PDF manuals on CD are about $20.Does anyone know if a comprehensive set of shop service manuals is even available for Yamaha Portable Generators? (gas and diesel) I don't mind paying, but I don't want just ONE manual, I want 'em all. That way I don't have to go through this again when a different model Yamaha comes into my shop. TIA for any help!:-) ?

floor directly to the physique, and run your cord to a robust earth floor. those areas are obtainable at your community electric supply that sells living house-wiring factors, you will want a floor rod, clamp, and a few sturdy copper cord.

Q:I am installing a 7,7 KW diesel 110v generator on my boat. I need to know the main breaker disconnect size in amps

Is the 7.7 KW mechanical or electrical? If you have 7.7 KW electrical, I will assume you will be delivering 2 legs at 120 V and -120V; 7700 watts/240 v 32 amps so I believe the main breakers should be 32 amp each approximately.

Q:I think i'm looking for 5000 watts which should cover my fridges and a fan and light, maybe the TV too. I also think I want 120/220v, and one that uses unleaded. What about horsepower and rated output? Are those important? What's the difference between say a Cummins Onan 6500 at Costco (currently $250 off) and a $399 generator of the same wattage on sale at Home Depot for example?

we have a 4,000 or 5,000 that we use at camp it has a honda engine and we run a 50 foot single wide trailer with lights that are from 60watt-100watt a small fridge furnace fan 50in tv water pump and sometimes a medium size microwave but lights will dim if everything is on we have had it for 4 years we keep in in a small 3 sided box with roof and stays outside all year we bought it at lowes

Q:I really need to know to know this.@ two days old. my baby was subjected to a high level of diesel fumes coming in from the hospital vents. Due to testing of generators and backed up through vent. she was in the room roughly 30 minutes what kinda damage should I be concerned about. should I be concerned? how long would it stay in lungs and the blood? please if you know.thanks

It depends on the size of the room and how quickly diesel fumes are being added. The gas would not say long in the blood and lungs although the damage would still be evident to a doctor doing a thorough exam. The two greatest concerns for you would be brain damage due to a lack of oxygen. Essentially when you're breathing in any kinds of fumes you are depriving your brain of oxygen while also subjecting your body to whatever poisons are in the fumes themselves. The second area of concern would be lung damage. The tissues would suffer as some of the fumes you are talking about could have an acidic component and could burn the lungs to some degree. Have your baby examined by a doctor and tell him your concerns.

Q:If global warming is as bad as Scientists say, two hours a month without power seems like a small price to pay in the grand scheme of things. I'm sure theres a way to keep hospitals running and emergency services running. All shops would have to lock down I guess people would start rioting or something, but I would think there would have to be some sort of way to covertly have different towns and counties shut down for a couple hours discretely each monthmaybe at night when people are sleeping? Just a thought.

Why can't America shut off power for two hours a month? This reduces fossil fuel consumption by 0.1% to 0.2%. Those resources that make power, are not all fossil fuel powered. And this reduction is negligible. Besides, for the last few months, my power has been off at least this much If global warming is as bad as Scientists say, two hours a month without power seems like a small price to pay in the grand scheme of things. And produce NO measurable effect. I'm sure theres a way to keep hospitals running and emergency services running. Backup diesel generators in all cases, so we move from hydroelectric, nuclear, and fossil fuels with50% thermal efficiency, to fossil fueled generators with less than 33% thermal efficiency there. All shops would have to lock down I guess people would start rioting or something, Not in my neighborhood. We pretty much wander around to see who all had been blacked out too. but I would think there would have to be some sort of way to covertly have different towns and counties shut down for a couple hours discretely each monthmaybe at night when people are sleeping? Just a thought Minimum power usage then, so minimal effect. You'd need to turn it off in mid-afternoon during peak demand. And all the traffic lights stop working. Did you see Live or Die Hard? Either 9 persons in 10 needs to die, along with the support staff of plants and animals, or we need to live differently. Some incremental steps that will have some detectable effects: - ground all non-emergency aircraft flights, forever; - remove all dams (slowly of course), and stop all wells, and use solar power to coalesce water needs from the air; - ban all personal automobiles from cities, right after you implement mass transit that is faster than riding horses, to all in-city destinations.

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

This may sound stupid, but check the belt. Make sure it's actually on there. The Onan QD's sometimes throw a belt. I have seen them break too. Make sure that's on. You may have an internal water pump issue as well - impeller fell off, etc (rare but possible). Another issue could be a blocked radiator. If your radiator is blocked with sludge, you may not even know. I usually check various spots on the block, thermostat housing and radiator while running with a infrared temperature probe to see if it's actually getting hot BUT BE CAREFUL doing that because there's a risk of damaging your unit. That's actually a last resort thing. It may just be a bad high temp switch. But make sure everything else is right first. Full radiator, belt, t-stat (you already did). Oh, I just thought - make sure you have the right temp t-stat in there. The one I have in the shop (1997 7.5 Kw HDKAJ Spec D) takes a 71 Degree C (160 degree F) one. Anything higher will set off the high temp system I believe.

Q:i want to buy a generator for our company i want to know how to calculate current for 1000kva capacity generator. and also want to know control and protection are required for the same generator please explain.

OK - You have elaborated - At that voltage you will have about 2400 Amperes. I P/E You have a generator putting out about 1 million watts. Divide that by the voltage and you get the usable amperes at rated voltage. Drop that to 380 3 phase Y would transformer. With loss through this you will have about 2352 amps. But the voltage has dropped from 415 to 380 so the amperes will go up. You will have about 2500 amps available at the output side of the transformer. Remember this is TOTAL amperes across all 3 legs of the windings. Remember that The Power is ALWAYS equal to the VOltage X the Amperage. If one goes up the other goes down. That will NOT change. Transformers are 98% efficient so you must calculate the initial loss through the primary transformet before you calculate the oiwer available for your main buss. If you have 1000 KVA before the transformer you will have 980 KVA at the out side. At 380 V, 3 phase you will have 2578 Amps. 980,000VA/380V 2578.94A OK So far? For safety you have to derate the system by 20% to prevent overload and burnout of the Generator or transformer. you have 2000 amps at 380 volts. That is on your main buss in the master control panel. You have a master breaker there feeling smaller buss lines. On each of these is one breaker per machine OR you can take sub feeder lines to sub panels throughout the factory. From these sub panels you can distribute 3 phase for motors and secondary panels for 110 or 200 single phase for lighting and hand tools. This is so complex and I want to tell you so much. How about I go there and do it.

Q:I have a generator in the building I am working on. It appears quite dated, but its stats are as follows: it’s a 415 Volt 3 Phase Diesel Generator.On the plate of the generator:415V3 Phase640KVA520KWPower Factor 0.8902 AmpsSo my question is:We are testing the generator to its full load, now my load is at power factor 1. Would I be correct in assuming that because my load is power factor 1 that the full load of my generator is 640kW not 520kW.Or is it that my actual power loading is rated at 520kW, but that load is allowed to be inductive or capacitive to 0.8.Because it says 900 amps on the plate I am therefore under the assumption that regardless of my load characteristics, as long as I do not exceed 900 amps there should be no problem. Or is it a case that my load can only be 520kW and the highest I can allow the phase to go out is up to 640kVA.Hope that makes sense, ill edit if not. Thanks for reading.

Treat all of the figures as maximum rated outputs. The maximum power it can delivery is 520kW, that is why it says 520kW. 640kVA and power factor 0.8 should not be be exceeded either but if your load is pf1 then the 520kW will take precedence. No offence but anyone who can't interpret these numbers shouldn't really be testing equipment of this power.

Q:I have a small one bed one bath home probably not over 1000ft what size portable honda generator should I buy?

The generac web site gives some good starting information. Make a list of what you must power with the unit. Add what you would like to run with it in addition to the first list. When purchasing the unit it is better to have a unit larger than your figures suggest rather than the exact size or too small. Honda units are reliable and quiet, also they are gasoline powered while some other brands are LPG or natural gas or diesel. Each fuel type has advantages and disadvantages. For an emergency portable power source a 7.5KW unit will do for most homes. For a back up power unit you will need at least twice that size and some other electrical equipment. Many motor homes have generators between 5 and 10 KW. Good luck to you.
