        Tripple expansion engines are so cool!
        The first piston is small and is fed the higest pressure steam. When it is exhausted at a lower presure it is fed into a larger diameter piston at a lower presure. Then that cylinder exhausts to a larger still cylinder which uses all the rest of the left over steam.
        You get to use the same steam three times on the same shaft.

          Not to hijack this thread any further but have you seen or heard about Ilmor's "6-cycle" engine they've been working on?

            Ilmor's experimental engine (unveiled last year) is a 5 stroke.

              What are the five strokes?

              Intake, Compression, Power, X factor?, Exhaust

                Didn't Isky make a cam years ago that made your engine into a 5-cycle?

                  Intake, compression, power, power, exhaust.

                  It's an inline-four that is really only two. The two outer cylinders fire and then exhaust into the two inner cylinders which then get a bit more work out of the hot gas before exhausting it out the pipe.

                    I believe it's a 3-cylinder engine.

                      Here's an explanation with drawings of the Ilmor 5 stroke ... it is 3 cylinders, with the center cylinder used to re-use the exhaust gases from the outer two cylinders.

                        I need to start fact checking my posts. Too much education really can fry your brain kids.
