Dolly is my LG brand Lister type 6/1 Diesel, manufactured by G.G. Automotive Gears, Ltd. This is one of several companies in India that are currently making replicas of the Lister CS series of Diesel engines. This engine was originally built by R.A. Lister & Company of Dursley, England, beginning in 1930 as the 5 H.P. 5/1 model. See Peter Forbes' page on Lister history for further information. Lister quit manufacturing this engine in 1974, continuing to build the similar 8/1model through 1987. Though it was no longer profitable for Lister, there continues to be a demand for this type of engine in places like India, Iran, Iraq, Australia and others for various jobs requiring a very dependable, durable, economical engine. Irrigation pumping seems to be their major use. Dolly was one of a batch of engines imported by Mike Montieth of Rutherfordton, North Carolina. Unfortunately, though these engines will likely continue to be made for a long time in India, new EPA regulations will prohibit their future importation. This is a lovely engine, easy to start, simple to maintain and repair, and quite sturdy. (Dry weight of approximately 750 lbs for a 6 H.P. engine, running at 650 RPM!) This engine has Lister's cold starting system with a compression changeover valve. Peter Forbes' Web site has a picture of this. A second spherical combustion chamber is attached to the main precombustion chamber by a 1/4" hole, which can be closed off by a valve much like a faucet. With the valve closed, the compression ratio is raised to about 19:1 for better compression heating of the air for good starting and light load running characteristics. With the valve open, the extra volume in the chamber drops the compression ratio to about 15:1, to reduce the strain on working parts at heavy load. I'll eventually find some equipment for her to power. For now, I just enjoy watching and listening to her run! :-)
(I just figured out how to compress these things a bit better. I got it down from 1.4 MB as previously posted. These movies use the Cinepak codec.)
I've now built Dolly a trolley from 4x6" pressure-treated pine deck timbers, with P.J. industrial casters with 8x2" semi-steel wheels, and a handle made of 1 1/2" galvanized water pipe. My first cooling tank setup was unsuccessful. The tank was short, with the inlet too near the top, and had to be raised on an angle iron frame to get it high enough for proper thermosiphoning action. It shook too much with the engine running, quickly sloshing out enough water to drop the level below the inlet, interrupting circulation. I brought home and old well tank, which is 12" in diameter and 5' tall, or approximately 30 gallons. It works very well, and I have some pictures and a movie below from Dolly's first run with the "new" tank.
My next-door neighbors' house is in the background. They are patient and long-suffering, and have been very nice about my engine tinkering. :-)
You can see a bit of the dairy farm behind our house. Cally is sitting in my driveway. She's my buddy, and always "helps" me work on my engines.
That's my house in the background. (And Cally.) You can also see the forest of prickly pear cactus at the south end of the house, all descended from one pad I picked in front of a MacDonald's in Ozark, Alabama in 1979. (Ouch!)
Dolly, with Cally yet again. If you have the bandwidth to download a video, you can see how stably she runs on this trolley, and that the tank sits very securely with two guywires pulled across the top.
Dolly with her tank newly painted purple. (Not yet decorated by Jennifer.) Not apparent in the photo is the new mounting of the tank; it has been countersunk into the frame rails 1 1/4" with a router, then the guywires crossed over the top and tightened down. A very secure mounting.
This is a picture of Dolly with her new Voltmaster 5 kW (6 kW peak) 120/240V 60 Hz alternator mounted on the front of the cart, belt-driven from the flywheel. I know that this engine is only rated at 4.4 kW at the flywheel, but I've run her with 4600 W electrical load on the generator. Her injector rack was almost, but not quite, all the way out.
This one suffers from sun glare, but you can see how the generator is mounted on a hinged board, with a turnbuckle to tension the belt. It uses a 7-rib, 90.5" serpentine belt. Mike Montieth made the driven pulley on the generator, and it is beautiful!
Here the generator's hooked up to a useful load! This electric grill draws 1760 watts. It cooks just like a charcoal or gas grill.
Cooking with gas! No, Diesel! ;-)
