    Default The Duke Engine

    An interesting concept from our football enemies across the ditch.

    How the Duke Engines increases the efficiency of the internal combustion engine

    I love it. I would think they will experience long term sealing problems at the interface with the rotating "block" with the fixed "head".

    But all the other advantages are as stated, fewer parts count in the BOM, reduced mass, higher specific output, compact size/shape.

    Great idea, but surely having the pistons move relative to the spark plugs and ignition is going to make keeping compression high nearly impossible? I mean, conventional engine heads are bolted down with a gasket, and this one slides.

    The Duke boys are a little slow off the mark. The swashplate engine has been around for about 100 years. Albert Mitchell was building them in Fitzroy Melbourne in 1920. They've been used in helicopters, planes and motorcycles to name a few applications. Swashplate motors seem to exist more as prototypes than mass produced power plants.

    Not mention the number air conditioning compressors that employ swash plate technology.

    Hi
    A new engine design come up every couple of years, that will put the old piston engine to rest Where are they all now ? There must be hundreds of them Still being pushed by their designers but nobody is listening anymore ! After a few backers loose their money it's hard to get more I've looked at them all with interest over the years. Some famous names spring to mind but who cares ?

    The old technology piston engine is a tough nut to crack and lots of man hours have been spent on getting it to where it is now. When this engine makes it to FI then I will look at it further.
