The reliability and efficiency of these engines is legendary; they helped save the English economy. There is one single-cylinder Doxford being slowly moved to the Anson Engine Museum where it will be restored.
I worked the old LB Doxford which were on ships built just after the war. Namely the NZSCo "H" boats. The were a great engine. They were a well balanced engine. On one ship we came half way across the pacific with the top piston on one unit completely broken away from its tranverse beam. We only found it when we had to stop for the usual water leaks. My job was looking after the fuel gear and the likes in the middles. We had twin 5cylinder engines with center scavenge pump. Jim M

Hello Alfons...i 'm late. I hope you are alaways there. My father seaman chief enginer made me a lot travels on cargos ships. I remember those engines. The sound and the oil/fuel smell are alaways in my mind. I am so sad that the big company had sold all the ships. in principle I should have continued the life on cargos too...
The shipping company I worked for had a few of these - mainly LB Doxfords. Biggest hassles were the 6,000 psi constant pressure fuel system, which was a real bugger to keep leak free, and the scavenge air pistons.
Super! a memory of the past.I've been told that the only big trouble with these engines was the possibility of water leak into the cylinder via the injectors sealing. I know at least one engine destroyed because the combustion chamber was filled with water, and at startup...well you can imagine!
I believe the Anson engine museum in Poynton are trying to aquire this enginefor their collection , chuck a few pounds to help their way to help them , i have . Also give them a visit , some real nice engines there & no I am not involved with them , I just enjoy what they have done
Exhaust piston, or upper piston, whichever name you like. And wot does an opposed piston engine look like to you? Trust me, that's an opposed piston engine, and if you're unfamiliar with it, you're VERY lucky.
I too did my time with the NZSCo and I am proud if it. I loved our Doxford Up and Downers and we used to have competitions to see who can change cooling elbows at the highest speed, the engines running if I recal at 106 RPM. Not only that but we would work inside a crank case while the engine was running. If you blew a relief valve on starting (maneuvers) it was case of beers every time. Great engines. Great days (Otaio, Huntingdon, Hertford, Hurunui, Piako, Cumberland and others.
i hear the oil cooled doxfords were tolerable.............unfortunately I only worked on water cooled ones. When the seals on the telescopics went it was inside into the heat
Quite a bitch to do maintenance on i hear. By opposed pistoned engine, i mean like those Fairbanks-Morse type engine with two pistons per cylinder, two crankshafts joined by a gear and no heads or valvetrain, and the inlet/exhaust is done by slots in the cylinder liner..
Hej! Zou ik deze video kunnen gebruiken voor mijn youtube kanaal? Ik deel alles over de zeevaart. Van vrachtschepen uit 1960 tot nu, olieboor platformen, vissersboten, binnenvaart etc. Natuurlijk geef ik credits naar de eigenaar van dit beeldmateriaal. Ik kijk uit naar je antwoord. Groeten!!
For my Wilton Fijenoord museum I picked up the Doxford model which was made by the Wilton Fijenoord school and was missing for 22 years! 🙂🎉🎊

Jnr,engineer on mv Baharistan and mv Turkistan with Doxford engines,magic!
My dad worked on some of these in ships during the 60s. I remember him telling me about the unusual sequence.

Hi Jim I well remember the H Boats, Cumberland and Sussex were my two. Sailed on a few J type Doxford's too.

Impossible work in crankcase on running engine BS
@@markbeale7390 Of course. You'd have to be a complete asshole to think otherwise. On the Doxfords the elbows are/were external.
Working in the crankcase when the engine is running???
Impossible

Mat,
I am Dutch, what you mean about "unusual sequence" ? The cranks on the crank shaft?
It's all double dutch

Jawel gebruik maar met naamsvermelding!
@@averheijden bedankt! Zal ik doen!
Hope bay, 1986
Thanks for your reaction
Isn't it the exhaustpiston you see? Doesn't look like a opposed piston engine to me...
Yes that is an opposed piston engine here is the animation www.acwhyte.droppages.com/downloads/animations/doxford_J_engine_animation_colour_&_text.gif
The top piston does uncover the exhaust ports,but it is a true working opposed piston engine.I sailed and worked on one.
