Listeroid Engines / Ever done this? Yeah I'm a REAL genius. (NOT)
« on: November 28, 2012, 02:16:01 AM »
OK, so I come home tonight, busy on the phone, see the batts need charging, start my TRUSTY DEPENDABLE Lister.
Working upstairs, I can hear it running, but something isn't exactly right; (again I'm on the phone...) and then....
It stops running.
UH OH.
I hang up the phone, go RUNNING down the stairs, mind going 400+ MPH, and figure out BEFORE I get there that no; I did not turn on the valve that feeds the engine COOLING WATER.
Yes, I am stupid. 100%, plus.
 I turn on the water, (thermosiphon) and hear it come BLASTING through the lines, starting to cool down this head that's HOT.
Using my temp gun, read 300+ degrees at the top of the head. BAD......
I tepidly grab the flywheel, and try to turn it, KNOWING that it must have seized.
It turned. Oh my God.

I started it, and watched it start. Watched the temps go down to normal.
The engine runs exactly as it did before my idiocy.
OK, so I am a moron. I agree with myself.
Now, WHY did this engine stop instead of either running away or destroying SOMETHING inside?

Listeroid Engines / DC Charging with 16/1
« on: November 11, 2012, 05:06:37 PM »
Hello all,
I thought I'd share with you what I am doing to charge a set of forklift batteries, big ones that weigh 2600 pounds, each. I have (2) of them in series making a 48 volt battery, and they are a total of 1105 AH, so they need serious amperage to charge them EFFICIENTLY.
 
So, here's the story:
I am using a 72 volt MARS Motor, like an Etec Motor, as both a generator AND a starter for the Lister. Here's how it works:
The MARS Motor is on a 6 inch NASCAR pulley, the Lister has a 24 inch flywheel, and runs at 750 RPM. It charges that batteries at around 6500 watts (6.5KW) in DC power, directly connected to the batteries with a diode in line to stop the battery from running the MARS motor.
So; when I start charging, and the batts are lower, say 60% or so, they'll get aorund 125 Amps shoved at them.
Once they start coming up in voltage, the amperage lowers some, and I still end up with 5.5 KW or so of charge. Right now, my batts are at 54.6 volts, and are getting charged at 102.7 amps=about 5.6KW.

Now, for starting....
I used a car battery (12V) & connected it through a solenoid to the MARS motor directly. Have a button for the solenoid that you push, MARS motor spins, driving the Lister to operating speed. It starts, and as soon as it does, it is generating MUCHO power to the batteries.

I'm working on using a Onan Twin Diesel military engine as a backup, cool thing about that one is that it is air cooled, and I'll tube that air into the house for heat....

Listeroid Engines / Slobbering etc.
« on: November 11, 2012, 05:42:53 AM »
Hello Folks,
I have a GM-90, 16/1, and it's still pretty new, rebuilt, I should say.
 Been running it at 750 RPM, with load, and it seems like I just can't get rid of the oil leaks. The crankcase is definitely pressurized, and I'm not sure if it should be. I changed/shortened the exhaust system to a short pipe with the muffin on the end, even, and it slowed the leaks down a little. I don't know what to do, basically, I've read that the crankcases are supposed to have some vacuum, and I'm certain this one is pressurized.
 Man, I love the engine, though. I run this thing driving a MARS (Etek) DC Motor, as a generator, for my 48V forklift batteries, and it makes just under 6KW (electricity) at the batteries at just over a half gallon an hour, and I think I can make that better with more break in, etc. The engine has maybe 25 hours or so on it so far.....

Help always appreciated, thanks in advance-
Chris

I did it!
 I FINALLY got my 16/1 done, and connected to a MARS (Etek) Motor, to use as a generator AND starter for my big old 16/1.

Here's the story;
I have a good sized house (3000SF+) that I took off the grid last summer. Have 1105 AH Forklift battery.
I have a Magnum Inverter/Charger that puts out about 60 Amps charging current, which isn't enough for the battery to charge efficiently.
So; I got a MARS Motor, this is a motor used in electric driven vehicles, golf carts, motorcycles, etc.
Long story made short:
This motor driven at about 2800-3000 RPM produces about 120 Amps @ 48-55VDC, so it charges my batteries MUCH better than the 60 amos from the 12KW generaotr head/Magnum Inverter's charger.
ALSO.....
I connected it to a 12V car battery, installed a solenoid & switch, and the same generator that gives me power (LOTS O POWER) also starts the 16/1 for me!!! (BONUS).

Anyways, the motor/generator cost about $485.000, I had to install a 150A fuse & a set of diodes to syop power from backfeeding from the battery, so altogether I'm around $550.00, not including the little mount I welded together for it, and the alternator bracket that cost $7.00.

This works really good, hope it helps any of you who need to charge large batterys.

Listeroid Engines / 16/1 RPM Adjustment Issues....
« on: November 27, 2011, 04:29:05 PM »
Greetings all;
 I have a 16/1 GM90 that I just rebuilt, and am having an issue with that I hope someone can point me in the right direction on.

My issue is RPM, I'm having a hard time getting it down low. I want it to get it down to 650 or so; but if I set it lower than about 800 RPM (running speed) it won't start (not enugh fuel?). So, just not sure what is causing it. Seems like, also, that when the machine starts & runs, after a while (a few minutes) the RPM's start creeping up, too.

Any ideas appreciated-
Chris

Listeroid Engines / Temps & Break-In
« on: June 10, 2007, 03:59:51 PM »
Hi Folks,
 As some of you have read, I'm just now starting a real break-in on my GM-90 6/1. I've got a couple of questions for anyone who knows about this.

On temps, I don't have a water temp gauge installed, as I haven't found the right fittings. Will this week. In the meantime, the engine has a thermostat that's a 195. I do have a temp gun, and I was looking at the machine yesterday with it. I was seeing 195-205 at the top of the head, depending on where I looked. As to water, on the outtake side, I was seeing temps from 195 (at the engine on the hose) to 225. It's a thermosyphon system, feeding water back to my Turbo-Burn waste oil home heating system.
 What's good temps for this, head, pipes etc.?
 I used Goodyear hose for this, and the outlet hose is connected to the base of the sight tube on my non-pressurized boiler. (Turbo-Burn). This sight tube is open at the top, and I figured that the water coming from the engine would flow slow enough for all to be good.
It was, until we started loading up the generator. It was running about 1500 watts, and had my wife go turn on the toaster oven. The generator pulled the load, but almost as soon as it did the coolant water kinda went a little nutso. Started FLYING out of the sight tube. (I only got hit by a little of it, but more than enough for me to understand how hot hot is).   
 My house is at over 3300 feet. Figuring a loss of 4% (I think) for each 1K feet, this 6/1 should produce 5.25 HP. At that rate, I thought I might see 3000-3500 watts. Is that realistic?

Also, keeping in mind that the generator is wired for 240V also, knowing that would limit each phase to 1800 watts or so. Logical?

On the break-in, any suggestions from you guys about how long, at what load/s & what to expect? Any temps I shouldn't exceed etc?

Thanks kindly,
Chris

Waste Motor Oil / Waste Oil Purifier
« on: June 06, 2007, 04:39:12 AM »
Hi Folks, I just thought I'd let you know that I posted a couple of pics of my brand spankin' new waste oil prurification machine.
 Any comments about my bad plumbing unappreciated from the start ;-).
Chris
