This is a detailed walkaround showing the progress to date of my "Daisy the Diesel Project". It was named by my 5 year old Julian who loves watching "Thomas the tank engine"
I bought this wonderful engine in Australia from a company called "Ozlisteroids." Their website address is www.ozlisteroids.com
Buying this engine was the beginning of a project that just kept growing and growing. The engine is an indian clone of the famous Lister CS "cold starting" 8/1 diesel engine. This particular one was made by the folks at JKSON diesel. It is an 8 hp model, making its power at 850 rpm. Here is a bit of a rundown of what has been done so far in this project.
* Stripped down to every last nut and bolt to permit proper cleaning out of the casting sand that we always seem to find in the indian made engines.
* All paint and indian body filler removed, then repainted in colours of our own preference instead.
* Built a frame to mount it all on, then set about finding and building on a number of interesting things for it to actually drive. There's nothing more boring than looking at videos of all these beautifully restored engines on youtube, which are doing nothing but turning themselves over and looking pretty! Diesels love to work, don't they? ! Well this one gets to work hard, and regularly. No glazed bores here...
The two major objects driven by my engine are a heavy duty 240 volt alternator and an air compressor.
The air compressor is a brand new 1950's made Bendix-Westinghouse truck compressor. It's about 8 cfm and air cooled twin cylinder design. It has an internal oil pump and white metal bearings, even featuring oil squirters under each piston crown! They don't make them like this anymore. We were lucky enough to find this brand new on ebay. The fellow had about 10 of them all still wrapped in wax paper in a wooden crate. It even came with the proper bowden type governor valve which you can see and hear working in these videos.
The alternator came from China, and is a copy of some old design. Heavy cast housing and most suitable for the slow running engine. It is four pole, only requiring 1500 rpm to produce 50 hz. The rated output is 15KVA or roughly 55amps, at 240volts ac, but it is not able to make this much when being driven by this engine. The engine is undersized for the alternator, which means the alternator is very understressed, so much so, it barely gets warm most of the time. So far the most we have loaded it down to successfully is about 27 amps, which is still quite a useful output. It will hold this output while still maintaining 50hz quite readily. It has an electronic voltage regulator rather than the old shunt type, which gives a nice clean, stable output voltage.
I have converted the mechanical governor to an electronic one, using parts from an Onan lighting plant. It uses a pulse sensor, which can be seen mounted on the end of the generator shaft. There is a flywheel/flexplate borrowed from a car providing the signal with its ring gear teeth. The pulses feed a processor which drives a solenoid. This controls the position of the injector rack and gives very stable engine speed control, which translates into excellent frequency control in the alternator's output.
I also ditched the original oil pump in favour of an external gear type pump to provide enough pressure to allow full flow filtration and the use of a heat exchanger. The heat exchanger allows me to get the bottom end up to running temperature quickly even on short runs, by using some heat from the cooling system. The radiator used here is from a Ford Falcon V8 and works well using thermosiphon only. There is no water pump needed at all in this system. The two fans seen on the radiator are 12 volt and are thermostatically controlled.
I set up a home made "oil alert" using a standard low oil pressure indicator switch and a relay. If oil pressure is lost any time, power to the electronics controlling the injector rack is cut, stopping the engine. There are lots of other odds and ends in this setup, including a home made gauge panel for both the mains voltage side and the 12 volt side. I am also experimenting with an invertor and deep cycle battery setup. This whole project has been about fun and learning. We do have mains power here, and it's quite reliable, so we didn't really need a generator.
We did have a power outage for three days recently though, and it made us very glad to have Daisy the Diesel! I hope you enjoy this video. Feel free to leave your comments.
