Changfa 195 diesel and generator
Starting up and running a Changfa 195 diesel single-cylinder engine, attached to an ST-10 60hz AC generator. Generator starts by crank. Test noise output with a sound (dB) meter. http://www.loligo.com/projects/changfa/

They are notorious for having bad internal radiators.

Nice vid, I’ve got the same eng and gen, Been panning on embling them belt style with a radiator, but I like how compact it is with the direct coupling. I’ve read about the couplings wearing out with the big singles, any probs?
thanks a small …
thanks a small engine what is the maximum KVA POWER output does it produce ?
Do it run well under a full load ?
Has anyone coverted one of these engines to run on biogas ?
Why did you go to …
Why did you go to external radiator? Is the stock one just not up to the job? Is your top block-off plate custom, and, if so, how did you make it? Will be cranking mine up today for a test run.
Thanks John!! …. …
Thanks John!! ….also for correcting me about the coupled speed!!
It depends on what …
It depends on what you value the most. If you value energy output, then a pulley system would probably be best, as you can run at 2200RPM and get the extra horsepower, even though you lose some energy with the friction of the pulley/belt. If you value simplicity and longevity more, then the lower-speed direct coupling makes more sense. Engines run longer with less need for repair at lower RPM. PS: The coupled speed is 1800, not 1500 (at least here in North America, where I need 60hz.)
An excellent video. …
An excellent video..!! I’d appreciate your informed, unbiased opinion on the following:
Please tell me whether it is better to run the engine at 1500 rpm & directly couple it with the alternator(like its done in the video),
or couple the engine to the alternator with belts such that the engine runs at its rated rpm(2000-2200) & the alternator runs at 1500 rpm(using suitaple pulleys)
One feels that the maximum output of the engine is not utilized, by running it at 1500 rpm.
Brilliant! That’s …
Brilliant! That’s going to save me a LOT of time reaming out the side hole. Thanks!
There is a tube on …
There is a tube on the inside of the plate on the return hose that takes the cooled water down to the bottom of the engine cooling jacket.
Nice job! I’ve been …
Nice job! I’ve been seeing the 195’s with external radiators with BOTH inlet and outlet on TOP of the engine. Shouldn’t one hose be down low on the block to create a thermo-siphon flow? Hot goes out top, get cooled by radiator, then flows back into the lower engine to cool it. The draincock on the lower side is ideal, but needs to be enlarged to 3/4″ for better flow.

‘nice job’ all around!!

I’ve still seen the Changfa 195-style engines with some frequency on eBay as “new”, so somehow they’re getting here. I am uncertain if they meet the EPA tier restrictions, though.

nice job! can’t get that engine here in the states?
Hi, Excellent vid! …
Hi, Excellent vid! Well built framework and radiator adaptor! Does it get even louder with a full load on it? I hope you are wearing earplugs due to almost rock concert levels. One of my projects is to emble one of these. I would like to make mine quieter, so I won’t wake everyone up within a 500 ft radius. When I come up with an insulated enclosure I will show it off on ‘tube! Again, thanks for posting, and nice application!
