Thank you, I have done some work on a Ruston Hornsby markCR for the museum it has air start but being a single cylinder its not timed to inject air on each power stroke, You just put it a little past TDC and hit the lever, if your quick and have good timing you can give it another shot but it usually goes on the first flip.
Can you explain the 4 push rods for each cylinder? i'm guessing there is just one intake and one exhaust,, is one directly operate the injector or something to do with the air start etc?
Sure thing, starting from left to right. First valve, air start, next exhaust, then fuel injector, lastly intake actuator rods. Engines of this compression and time of manufacture were started by air as electric starters powerful enough didn't exist, and air is reliable, stores indefinately (in sealed systems) and is relatively simple and common in marine service.
If you check out the video "voyage of the Arc" you can see me starting the engine by a lever that actuates the air start valves.
Wow thats awesome!!! Espcially for someone who love diesel egnines! What kind vessel is/was it in and what was/is it used for? Thanks for sharing!...Now if only I could find a WW2 Submarine's diesel engine vid.
Brilliant Engine/sound, and good to see it running in working conditin and doing somthing usefull! Look after her, and I'm sure she will last you well.
I know the engine was worked on at some point, but not in at least 40+ years!! At present she is still raw (or salt) water cooled and going strong. Not many of these engines are still around, even fewer still in the original boat, like mine.
The engine weighs 20,000 lbs!! Fuel consumtion pushing the 90 ton boat is only 4 gallons an hour at 9 knots!! Show me another vessel that size with that kind of fuel economy!!
Yeah, just make sure you get a titanium heat exchanger if it's going to see Atlantic salt water. My father used to work in the diesel engine business (Wartsila Diesel) and their engineers found that titanium is the only thing worth considering, that water eats through acid proof steel in a matter of months.
Interesting enough most engines design for direct cooling last a very long time as long as they keep going, the damage happens when you let is stand with saltwater in the system for long periods of time. That can easily be combated with running freshwater through the engine before storing it. Most old small Volvo marine engine are built this way for example, as well as nearly every outboard motor.
Look how the valves working!
soo beautiful!

Nice. Love the sound of those direct-reversing, low-RPM diesels!

Salt-water cooling? Ow. I dare not think what condition the cylinders are in.

The water jacket has very thick walls (.5" thick)and look good, but I do plan on converting to fresh water cooling soon.
