From my memory the RD and the latter RND did not have centre poppet exhaust valves. The RD again from memory had a rotary exhaust valve and the RND did not have an exhaust valve, it had hundreds of reed valves, in its loop scavange arrangemet. The RTA, I believe was the first Sulzer engine fitted with a poppet valve, similar in design to that of MAN B & W. But I stand corrected? Can anyone confirm.
Thinking about it, the RTA was the first Sulzer to have an exhaust valve, meaning that this engine can't be a Sulzer. The RD did have rotary valves and RND had reed valves in the scavenge. No matter how much you scrubbed, you could never get clean after 'cleaning' the scavenge!
Ahoy there , it's a B & W, 8 Cyl, 2SA. The engine was built by Götaverken, Gothenburg.Confirmed by Lloyds Register.
Engine model number believed to be 8K90GF but I cannot confirm this at the moment.
I am working on the horsepower (27,300 bhp ) & cylinders and this is the only B&W match I can find. Regards,Rick
Thanks Pat - I think this was first breed of hydraulic poppet valves from B & W, somewhere around the late 70's. 8 cylinders at 900mm bore. I sailed on a similar but smaller version, nice engine, far superior to any Sulzer.
That looks like a nightmare.....yes Doxfordman you are correct about Sulzer RD and RND I got to know every inch of the RD version on Cunard Brocklebank good motors and the RR alternators were ok just a bit fiddly and had cooling problems in Asian rivers !...john g
