- Q: I live in california, in the ventura count so anywhere close to there.
- Cities, Counties, and States each have surplus equipment sales. I have seen diesel generators in our State Surplus Yard. Another place is OKorder. How large a generator do you want? I can find one and give you the link.
- Q: Are they cranked by a self starter? Is there such an immensely powerful self starter that runs off batteries and can start such a big engine?Or are they started by some gasoline powered motor?
- A diesel engine is started (like an automobile) by turning over the crankshaft until the cylinders fire or begin combustion. The starting can be done electrically or pneumatically. Pneumatic starting was used for some engines. Compressed air was pumped into the cylinders of the engine until it gained sufficient speed to allow ignition, then fuel was applied to fire the engine. The compressed air was supplied by a smallauxiliary engine or by high pressure air cylinders carried by the locomotive. Electric starting is now standard. It works the same way as for an automobile, with batteries providing the power to turn a starter motor which turns over the main engine. In older locomotives fitted with DC generators instead of AC alternators, the generator was used as a starter motor by applying battery power to it.
- Q: I am trying to find the value on a generator we’re trying to sell which is becoming a real headache since the thing was made in China. All I know about it is it was made by Shanghai Tractor and Internal Combustion Engine Corp and it’s a 20kw diesel generator. It’s about 5 years old but has only been used once since we purchased it. How would I go about finding the value for this generator? I need to have it sold as soon as possible.
- Companies like China Star have become famous for diesel generators, so being from China is not a negative. Just look up any US made generator and reduce by about %30 to get value. I think a US generator of that size, which is sufficient for a whole house, should run about $2500. So as used slightly, I would start around $1800 I think. But you may have to come down to $1000 if the market happens to be slow. Check on Craigslist to compare. I am only guessing off the top of my head. It is contractors who buy them the most, and few people are building right now.
- Q: how does a generator work powerlessly. i mean like if there is a black out people cna generate energy from like a generator. well then how come a generator work without the help of anything? (NOT TALKInG About the hydropower generator, the one that spins.
- As pointed out generators convert mechanical energy into electricity. The mechanical energy is provided by an engine that uses some type of fuel like diesel or natural gas. All generators spin to produce power. well then how come a generator work without the help of anything? Backup generators do seem to magically produce electricity during a power failure Backup generators are fitted with automatic controls that handle the starting and placing of the generator onto the buildings power bus. The automatic controls are powered from the AC mains to keep a set of batteries charged. THe batteries are used at the beginning of a blackout to power the automation and start the generator. (Once the generator is running these batteries may then be recharged from the power produced by the generator or when the AC mains is re-established.) Electronic controls sense the loss of AC power and trigger a starting sequence. The generators starter is engaged to crank over the diesel or Gas engine. The controls monitor this process to ensure the engine actually starts and that an excessive amount of cranking doesn't occur. Once the engine is running and brought up to proper speed additional automatic controls disconnect the now powerless AC mains from the buildings buss and connect the Generator power to the buildings electrical panel. Based upon the size of the generator some or all of the buildings power may be supplied by the backup generator. Without the automation the process is still the same except a persone would have to perform the process of starting the gen and placing it on line. Its not difficult to do but does require some trainng. Automation performs this startup process quicker that what a humam would be likely to do.
- Q: What is the maximum power of a diesel generator
- in the piston upward pressure volume temperature rises rapidly reaching the ignition point of diesel.
- Q: I need the information to do a science project - how is this electrical energy stored?
- It's funny you should ask because I was just researching the wind energy subject while looking at getting a job with a company that makes generators. Generally I've found that it isn't! Wind power is usually expected to be supplimental to the power grid because you can't depend on it 24/7. The only exceptions to this are remote areas where they have no power grid access and even then they usually have diesel generators too. I have seen small ones on sailing boats where I'm sure it just tops up their batteries. Waste byproducts are zero or even negative. I say negative because in a lot of places the excess power is fed back into the power grid reducing the need for the other power stations to pollute as much. In fact the only bad things I've heard are from those that think they are an eye sore, those that think they are noisy (which generally are not) and those that think birds will crash into them. it's funny that they don't complain about the glowing ones that nest at my local nuke generating plant tho ;o)
- Q: First of all let us get down to the corruption of all of this hoax created by Al Gore which is nothing but a scheme to put the public in fear. This will stop all of the money going out to create bogus programs. Next, let is realize that hybrid automobiles mpg results have been overinflated by the corrupt EPA. Since they have been caught, now they are doing real world tests. Now, let us look at what Europe is doing with automobiles. CLEAN DIESEL. These clean diesels consume far less fuel than gasoline motors of the same size. They are getting quieter, no longer smoke, and are as fast as gasoline cars in some cases. Mrs. Speaker, I challenge you to drive one of these cars and you will be surprised. However, I think the public should decide on whether Global Warming is true or not. I do not want you and a hand full of others control our lives when we vote you in there to work for us.
- First off, let me applaud you on your view of Al Gore too.glad to see I am not the only one who believes he is making a mountain out of a mole hill. Secondly your MPG is not quite accurate. The reason why the mpg rating by the EPA is overinflated is that the test they previously were using was out dated. The test was putting a car in a controlled environment at a constant 55 mph.does that accurately portray actual driving conditions? I dont think soso yes it was outdated and has been modified to give more accurate ratings .and the EPA is not corruptdon't let a few people's misguidings stereotype the agency as a whole (i am an employee and not corrupt). Clean diesel has that stigma and stereotype among americans.regardless if it gives better gas mileagemy theory is that until something EXTREMELY drastic happens, we americans will still be in love with gasoline and will take a nation/worldwide catastrophy before we look beyond gasoline.IMHO
- Q: Hi, this may be a stupid question but im a city slicker planning on campong and i want to buy a honda generator, What kind of fuel does it use? where do i get it? thanks.
- ask the people in the store where you purchase the generator. most generators use regular gasoline, but some bigger ones use diesel.
- Q: I want to place a quiete genarator which is about 7kva. Will it disturb people in my apartment? We usually make a lot noise in the building. But doesn't sound a lot also?
- a 7kva generator isnt even that quiet. i know they say quiet but theres only so much you can do. why do you need a generator anyways? and yeah it probably would disturb the people in your apartment.
- Q: An electrical power system consists of identical diesel generators, each generator. Has a constant failure rate of 0.5 per year. Calculate the reliability of the following arrangement-three months after the initial commissioning date. 1. Only one generator operating. 2. Only generator operating, one generator standby. 3. One generator operating, two generators standby.
- 0.5 failure per year would mean 1 failure per 2 years. Keeping the generator off for 2 years is no good, it may not start. It is best to operate the machines at least once every few months for some length of time. The longest time to failure is usually achieved by sharing the load and operating all equipment simultaneously. This method is very application dependant! Hope this properly answers your question
