Engine Concepts...

Considering the sleeve would have to fit inside the 7 minute cylinder module and would probably cost as much to make while adding at least two more failure points, what is the point?

I found his resume. It is Kerberos Solutions, not Kaberous. His website either was never built or was suspended according to the message if one clicks through again.

Yes, that is it. I misspelled this too.

What are the two additional failure points?

You have to ask?

Not to mention that at the phenomenal pressures you are talking about running, those liners will be ringing like bells and will probably be holed or cracked by cavitation erosion very quickly.

The reason I asked is, I thought you might be thinking of O-rings. I am thinking of a different approach. One is a press fit by heating the jug and freezing the sleeve and the other is casting the sleeve in the jug. Before you jump me for a previous post, where O-rings were mentioned, the context was past experience with o-ring failures. The press fir might occur before the jugs were machined. Which approach would you think would work best? O-rings, press fit or cast in

I am also thinking about using Evans Coolant. No cavitation, it will not pass an electrical current and it is biodegradable.

If the object of this new design is to have quick change cylinders then why not just use a parent metal bore, save weight, save money, and save having to jump through hoops to reline a cylinder, if is even possible or practical. Make those 7 minute marvels too cheap to bother with.

You have the idea.

With all due respect. If boats had zippers on them, that might be an option. Boats engine replacement is expensive and timely, even if you don't consider the cost of the engine. I remember a new 65 sport-fisher that was on it's maiden shakedown cruise and had an engine problem. Both V16s had to be removed and replaced. The issue turned out to be dirty crankshafts. After the cranks were machined, they were not cleaned properly and the metal cuttings cut the bearings to pieces. On one engine it seized and spun a main bearing. The cost to remove and replace the engines, I am told, was close to 400 thousand dollars. I am sure that that boat owner was livid. In this situation, I can imagine all sorts of law suits. John Kelly could make some money here. Smaller and lighter parts that can be carried out through small openings is the only approach that solves this issue. Cost is also a factor, with the engines themselves. Most people might be able to come up with 15 thousand for a rebuild but 60 thousand to replace an engine is a bust.

With all due respect. I think now you are thinking too much and overcomplicating your engine. Wet liners with o-rings etc. The 92 series of DD's have wet liners with o-rings and they are responsible for a good amount of their failues. I also think press fit liners where you need to freeze the liner and heat the block are also making things way over-complicated for an engine touted with easy rebuildability in the boat. If you look at the dry liners in the 71 series of DD's. They are easy to change without heating anything up, freezing anything etc, and reliable. Same with going with very high coolant pressures. There's no shortage of raw water supply in boats to cool the coolant off via heat exchangers, no sense to over complicate that either IMO. I think the KISS aproach is the best in most cases.

Man uses individual cylinder heads and they have a lot of advantages over a single bank head like CAT, it's a nightmare to get a C32 cylinder head into and out of the engine room for example. Easier to remove them from the boat (size/weight), easier to rebuild one cylinder or fix one head. But there is also a little more maintanence that goes with that, cylinder head bolts have to be re-torqued on a more frequent basis, more gaskets to leak (each valve cover), etc.

on what may I venture to ask?

Concepts

Maybe I should clarify that the processes I am speaking of are done at the factory and not in the field. The cylinder jug comes with the liner in it. It is nothing but a switch out. Single light cylinder head and single light cylinder jug. All of the gaskets on the proposed engine are O-rings. Each cylinder is monitored individually and when needed it is replace as a kit with new o-ring gaskets.

Big engine room. Most don't provide this advantage.

I am taking a seminar that you guys might find interesting. It is offered by a company called Equilibria. You take a test and the test reveals your E-Colors. You can take the test on line at no charge. Here's the link.
