does the sterling engine have the best thermal efficiency of the heat engines?

[lapere71]

@skittlesmonkey No. At the moment Wärtsilä marine diesel has best efficenecy of reprocating engine i suppose. With exhaust gas steam turbine it has about 60% efficiency

[cheaphardwarez]

That would not be hard to make, good idea!

[lapere71]

engine is almost done ...

[VideoJunkei]

so the pauses allow more time for heat transfer?

Makes sense...max power, but top speed less from stop/starting?

[lapere71]

pauses allow ideal stirling cycle engine. in other words, perfect pressure - volume diagram.

You all claim there is resistance at the cam.

Ever seen a roller-rocker head? One oval bearing on the end of each post solves it perfectly.

Quit thinking a conceptual model is an final engineering design.

[CraziestOzzy]

too much friction on the cam...go the "free air piston" way

[hboy007]

OK, now use a series of hot and cold cylinders that are connected to crank shafts running at multiples of the base rotation frequency to describe the volumes over time in two (very) finite fourier series.

wouldnt work



[stopglobalswarming]

perhaps if the pistons were on opposite sides of the "cam" device, much of the friction could be eliminated.

its off timed the pistons shuld be half turn off i spelled should wrong i know
