Also, if i were building it i'd have a seperate crank for the inlet and exhaust, so timing could be played with, also simplify machining as a regular crank would do rather than something with fancy offset journals. turbo 16v k-series 11.9@118.9 :)

and angle the top pistons so the airflow path was smoother.

Interesting concept (Denis' one) to apply piston valves to a four stroke IC engine but piston valves themselves have been used for centuries on things as mundane as a steam locomotive.

i was thinking about this all last night. conventional engines can get >100%ve by keeping port velocity up and all the usual tuning tricks. I wondfer if it may actually hurt having the ability to have a humungous intake and exhaust CSA, as gas speed would be low... better for turbocharging? turbo 16v k-series 11.9@118.9 :)

yes I think it would hurt denis , but the size of the the valve pistons could be made a lot smaller than the power piston and so reduce the scale of the tracts ? Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM |

i know the deltic engine, but the engine im thinking of is a 4 stroke. im going to have to find the damn thing now! incidently i stumbled on a video on youtube about a year old where a collectors deltic was brought into service to haul freight for a while. love the sound of them. At the risk of going off topic for a second, the engine was hired out from the railway museum in York and was used to haul freight around the Blyth/Cambois area (there was a short piece in the local free paper about it a couple of years ago) when there was a shortage of available engines. As it happens I was kayaking with my eldest on the river Wansbeck at the time, heard the distinctive sound as the engine powered on as it crossed the black bridge - wonderful sound. Can't explain it, but it reminded me of an air-cooled 911 (sort of!). Kind of a powerful, refined but not-quite-the-norm kind of sound. Great to see/hear it though, and the best kind of example of keeping engineering heritage in the consciousness. Now... when is Mallard/Flying Scotsman going to be called back onto the East Coast main line? Now - back to unusual engines... |
