the art of engine

The article I read referenced a piston wear rate of .03MM per 1000 hours. Don't know what is considered worn out on something like that.

Maybe its like the Golden Gate Bridge; never done. They just keep pumping oil in one end, and pumping it out on the other...


How about this V-16? 640 bhp @ 11,500 rpm. Crafted from 4 Yamaha 1000's.

One of the Navy ships I served on was diesel engined. Two 3000 hp 9 cylinder Nordbergs. We never changed oil, but we ran continuous purification on it through DeLaval centrifugal oil purifiers.

They are designed to be overhauled in place. Some big engines can actually be shut down. one cylinder disconnected. Restarted and then run without that cylinder, They can do liner and cylinder jobs with the equipment on the boat.

ship will probably be scrapped before the engine needs an overhual

We had a spare cylinder sleeve and piston hanging on the after engine room bulkhead. There were chain fall tracks over each engine.

The GT-40 engine up top has a reproduction Shelby block. You can tell because the Shelby blocks have two side bolts per cap, where original Ford 427 blocks only have one.

Yeah I know... Call me the Klay of Ford engines. I'm a detail Nazi - Eeet must be correckt!

The quick way to tell if it is an FE engine is to look at the intake manifold and valve covers. The FE intake goes under the valve covers. If the valve covers are off you can see the pushrod holes going through the intake and not the head. Very distinctive feature of the FE. Same if it is the little 332 or the big 428.

I appreciate the correction. I didn't have information on that engine but the photos were from my visit to the Shelby Cobra Museum in Boulder - a wondrous place for motor heads.

My take on the double crossbolts is that the block is aluminum and needs the extra support because the skirt isn't as strong as cast iron.

At the time that Ford was competing with these engines, I was working for the company in a research area. I saw the 3 valve heads that would have gone to LeMans if the French hadn't changed the rules to prohibit the big engines. The flow lab boss said they were flowing 550 CFM per cylinder.

^^^^ Kaase!! ^^^^

http://www.jonkaaseracingengines.com/ Plenty of engine porn on there. That's an easy 750 HP on pump gas, with plenty of vacuum to run power brakes, etc.

Those things are da bomb!

Yep, it's a piston out of a Ingersol Rand KVS 26CT Engine. This one was over limits on out of round and was pulled. The bare piston weighs 400lbs so it makes a nice solid vice stand.

Here's a few pics.

The piston has two threaded holes in the dome of the piston that are used for attaching a pulling tool to remove the piston from the engine. I just cut a piece of plate and drilled two holes so I could attach the plate to the piston with bolts....worked great.




This is the KVS 26 engine, it's rated at 1000 HP at 330 RPM and drives two integral double acting compressors. This engine is used to compress natural gas on a pipeline and is the smallest engine/compressor on the pipeline.




Inside the KVS crank case taking crank thrust readings. The power rods are removed in this pic so the power pin is wrapped in cardboard to keep it from getting scratched.




Here's a few pics of one of the larger units, It's a Clark 12 Cyl two cycle engine driving three double acting compressors, it's rated at 4500 HP at 300 RPM.









I have more pictures of the Clark here: http://www.advrider.com/forums/showt...ight=hodakaguy
