Re: bolt materials for Korean and chinese shipbuilding

Well I reckon all those markings on those foreign bolt heads translate ( according to my translations dictionary ) as non sparkers type jobbies.
The content metal material comes up as,
Wait for it,
SHITMETAL

Which allways used to be in the old days as diecast zinc content

Re: New engine

Well from my point of view I say keep running on all six Andrew as when all this fuel oil/ stinky gas/ lecky propellants expire your non turbo counter turning balloons ideas will come to the forefront and patents will become necessary. Not too sure about the thermal / pump / blower version yet. The ...

Re: New engine

That's all very well Andrew but what about the mirrors?
What's a Bucklet?
Could it be a mini bucket?
You know, like six buckets in line?
Six cylinders in line?
What's flowers got to do with this " power plant ? "

Flower power maybe?

Re: New engine

Seems to me that when balloon one ascends the drum turns clockwise and when the other ascends the drum turns anti-clockwise? How can this constant change in rotation be transmitted to the " generator " in order to provide a constant current output? Also the generator seems more like a old dynamo ( d...

Re: Calcium Carbide Lamps

Not wishing to cause people nightmares ref my Carbide Light letter and as to date no one seems foward enough to own up their association with same, thereby disclosing age I follow with an more amusing story ref the light. As no one has owned up to personal knowledge I would conclude therefore that ...

Re: First Timer

No problem Martin, I am figuring ( as I believe you folks over there say ) that by keeping in with the Marine Engineering world version of the Man With The Sandals on that should I ever get tired of fiddling with flame ring protrusion heights etc that whilst awaiting a report from the Ginger One (wh...

Re: New engine

Super bit of kit with Santa flying around in your somewhat large shed you have over there Andrew. Perhaps you could design a turbo version which would carry a large payload of a fistful of dollars and route it over my way in time for a New Years present? Back to practicalities I fear that there coul...

Re: First Timer

Nice to hear from you again Dave and Big Pete and a happy Xmas to you and yours and all the best for the coming year. This Diesel engine fitted with a spark plug for each cylinder displays some most peculiar traits many of which I have never encountered before. For example a simple plug change consi...

First Timer

After nearly 60 years in the trade I find myself today on a ship with 4 diesel engines fitted with spark plugs.
No, not glow plug/heater plugs ( although it does have them too ) but Spark plugs.
So what's the score here then?

Re: New engine

Felix, Concerning your write up re timing, do you refer to valve timing and/or injection timing? If injection timing is it Common rail timing or the ( now old ) mechanical system? If Common rail whose system are you referring to ? If the old mechanical system duplex or single chain? Spur or straight...

Re: New engine

Greetings Alex, What a super illustration of valve bounce and obviously well knackered guides. If that depicted valve is an exhaust one and the wrist watch engine depicted has run for many hours then the red hot gases flowing continually across its seat during the bounce cycle must have been apparen...

Re: Daihatsu diesel generator troubleshooting

RESISTANCE is the word applicable here. Everyone must have encountered it in some form or another in their lives. So Mr Ohms and that upside down circlip symbol denoting the unit of resistance is how to measure each and every cylinder compressions accurately and very quickly with no dismantling what...

Re: Daihatsu diesel generator troubleshooting

It appears to me to be somewhat of a problem here engineering wise to crack this one? As there are more than one ways of skinning a cat ( as they say ) perhaps a different angle of attack might be the way to go. A personal approach maybe. So I put it to you in a different format. Winding back the ol...

Re: MSC Opera Crash In Venice

Perhaps the same team who designed the system used to work for Boeing, they have it worse that computer taking over and bringing down fully loaded aircraft. Perhaps computer designed systems...
