Re: [MBZ] OM617 conversion to generator
I have one of the Generac units in my shed for such an occasion. I have no
plans to set up a switchover box - I
just plan to run extension cords in through the windows and if necessary will
disconnect things like the furnace
from the house panel and feed from the generator. We don't have many power
failures but if we ever do in a bad
weather situation, at least I have the ability to keep some basic items running
for a while. I stuck with gasoline
on the assumption that I can drain it out of my vehicles as an emergency
supply. At this time, I have 2 gas
pickups, a gas SUV and a gas car and if they each have a half tank, I will have
quite a bit of gas to run the
generator. If it was a more common occurence to lose power, I would be looking
at a Lister type diesel and a big
generator but so far I have not had the need for it.

For many years, Generac ("Genecrap" as they were known
in the industry) tried hard to compete with us big
boys in the spec market, something they were never
successful at. However, they finally got their act
together anc concentrated on the consumer side, where
they have been very successful with the small home
standby units.
I have a good friend that's a Generac distributor who
sells tons of these things. I knnow that the big box
retailers like Home Despot do as well. They're very
well designed and packaged, and if I wanted a small
stationary home standby unit with a transfer switch
("switchover gear") I would probably go with one.
As for LP as a fuel, the choices are no-brainers,
mainly due to the storage issues. The only bad thing
about gaseous fuels is the lower BTU content, but the
manufacturers have taken that into consideration when
sizing engines.

Most UPS systems are entirely out of the line _unless_ the incoming power is lost. Sometimes they include filtering, often they include some transient protection. Rarely are they correcting frequency or voltage. Computers will not really care if the frequency varies - within reason. They use switching-mode power supplies that usually are rated for 100-120VAC 50/60Hz. It's not unusual to find one rated 100-240VAC. So in general, as long as the supply power is _clean_, computers aren't very picky. Monitors can be a whole different issue. -- Philip ___ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Not so! Having been an electronic design engineer and designed power supplies, I can state that the properly designed ones are not that frequency sensitive. Even when iron-core transformers were the norm, a 57 to 63 Hz operating range was what was typically specified. Nowadays, with switching mode power supplies, electronics are even less sensitive to frequency of input. Witness my laptop's power supply, which is spec'd for 100 - 240 VAC, 50 - 60 Hz. It will probably be happy even outside that frequency range. ___ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] OM617 conversion to generator
More like 0.746 watt to 1 horsepower. And that's a textbook conversion. If you're starting high inrush loads like motors or inductive heaters, you gotta be able to handle the inrush current, which in small HP motors can be as many as 6-7 times the running current. That's an area where consumers run into trouble. They look at the nameplates of all the appliances and other goodies they want to run and just total up the wattage. Don't work that way...

Re: [MBZ] OM617 conversion to generator
My Generac runs at about 63Hz lightly loaded but slows to about 61 Hz with about 50% load (like the water heater). There are instructions for adjusting the governor but I haven't done it. Also, we notice the lights get brighter when the water heater clicks off. This system has a mechanical governor for speed and an electronic voltage regulator. We haven't noticed any ill effects except the clocks gain time. Of course, my PC is on an UPS so it would not be effected but the TIVO, TV, etc only have surge protectors and they were fine.

Home Depot had a "Buy $2000 worth of tools and generators,
get $500 off" sale back in April. The 7kw Generac standby
unit was $1999. Throw in a cheap hand tool to get the purchase
over $2k, and you're out the door for less than $1600 including

Re: [MBZ] OM617 conversion to generator
For many years, Generac ("Genecrap" as they were known
in the industry) tried hard to compete with us big
boys in the spec market, something they were never
successful at. However, they finally got their act
together anc concentrated on the consumer side, where
they have been very successful with the small home
standby units.
I have a good friend that's a Generac distributor who
sells tons of these things. I knnow that the big box
retailers like Home Despot do as well. They're very
well designed and packaged, and if I wanted a small
stationary home standby unit with a transfer switch
("switchover gear") I would probably go with one.
As for LP as a fuel, the choices are no-brainers,
mainly due to the storage issues. The only bad thing
about gaseous fuels is the lower BTU content, but the
manufacturers have taken that into consideration when
sizing engines.

Re: [MBZ] OM617 conversion to generator
There are plenty of industrial diesel engines out there running with "standard" IPs in constant speed applications. The only real benefit to modifying the pump for such an application would be to increase longevity or reduce manufacturing costs. The generator industry is full of what we commonly called "assembled" units, meaning a supplier did nothing more that purchase an industrial engine, an alternator with voltage regulator, and a pre-packaged set of engine controls. Flywheel housings are standardized as are flywheels and couplings, so there's almost no engineering involved. The tricky part is the engine controls and governor. The easiest and cheapest method of frequency (speed) regulation is a mechanical, or flyweight governor. There are only a few manufacturers out there, and installation is pretty straightforward - you only need a belt to drive it off the engine and linkage to connect to the throttle. The problem here is that mechanical governors, on a good day, give you about 3% - 5% regulation. For today's electronic devices, that's not very good. At 60Hz, +/- 5% is 57Hz to 63Hz. Your computer and other frequency sensitive devices aren't going to be happy. They may very well work, but you're on the ragged edge. Take that down to 50Hz and the window opens up even more. There are lots of electronic governors out there, also known as "isochronous" governors, which will maintain a much tigher frequency (speed) regulation. However, with tighter regulation comes higher costs. Companies like Barber-Coleman and Woodward dominate this market, and make many bolt-up,, off the shelf governor systems that work independently of other engine/control systems. Another issue you run into when operating at the lower end of the torque/horsepower curve is throttle lag. Because you don't have the advantage of engine mass working on your side like you would at a higher RPM, variations from load to no load and vice-versa are far more pronounced because of limitations in fuel system operation. A good example of this is the predecessors of solid state UPS systems, which were nothing more than motor generators (an electric motor, a big honkin' flywheel, and a generator.) These not only provided a different power source for mainframe computers (400Hz) but they also acted as a UPS. The inertia stored in the very large flywheel would continue to spin the generator for several seconds when the motor was powered down (power loss) providing power to the computers. The flywheel also dampened response of the motor and generator speeds. You could do much the same with an engine generator if you wanted to put a monster flywheel between them Anyway, I've rambled on enough as it is. Can you tell I was in the business for 20+ years?

That works best. An RPM governor is the least effective with a voltage monitoring governor right in the middle of the two for steady, clean power.

Can the existing MW pump be > converted to operate in constant rpm mode? Probably, I think the tradeoff between constant-rpm and constant-torque (if you will) is set by spring ratios, but finding someone who knows enough about it to actually make that conversion may be difficult. You might contact your local Bosch pump shop to see if they can help. The one here said they only saw such pumps every couple of years, however, and had little practical experience with them. They offered to have me send mine out to some shop in CA! (Cummins/Dodge 24-valve rotary pumps, on the other hand, they work on all day every day...) The IP in the Frankenheap (vacuum-operated) seems to be a 'tractor' pump already, it definitely drives a bit differently than most other cars. The cruise control system could be adapted, but I'm sure the PID feedback loop constants are all wrong for that mode. I personally would be more comfortable dinking with one of those than the guts of the IP, your mileage may vary. It would be better too, if you planned to have the engine as a spare for one of your rides. Less modifications to undo. The speed control doesn't need to be all that elaborate to be practical, my Hercules just has a flyweight governor that runs the throttle plate. If all you need is 10kW you'd probably be better served with the 1500 RPM 4-pole generator head. Quieter, and probably much thriftier. Such heads are generally much better constructed as well, and much more likely to last longer. -- Jim ___ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] OM617 conversion to generator
Exactly. Figure 2 hp per kw to be safe. You should be able to run a gen bigger than you could use in an average house with that engine at 3600 but it is going to load up and run like crap at 1800.

Re: [MBZ] OM617 conversion to generator
MBZ cruise sucks...It is not even close to good enough to keep the engine at a steady enough speed under changing loads to maintain a steady voltage and frequency. It could work, but not very good for electronic equipment. You could generate DC power and keep a battery bank charged to run a large inverter but that is probably too costly for what I think you want to do.

Unless I am mistaken you will want to have a feedback system such that the engine speed is determined by the frequency of the output.
