6 stroke engine idea?

Seems there is a special oil used in steam engines

Aye, steam locomotives were durable, but used a scotch yoke to eliminate side force on the pistons, and were still very high-maintenance.

I thought I would point out that by trying to use the latent heat in the cylinder to generate steam will cause the normal combustion cycle to run like an engine that never warms up. Also the exhaust will be cooler and emissions controls won't work.

Very good points. The summation of responses thus far must coincide with why Crower has had this idea for years, and never gotten it into production, or even publicized demonstrator vehicles (as far as I've seen).

BMW's turbo steamer idea, using the exhaust heat to drive a seperate turbine system is a much better idea, albiet very complex.

not to mention you'd be looking at a 6 cylinder to start with to always be having a fuel power stroke.

instead of a cooling system, you'd be looking at a heating system, with a heat exchanger to pull heat from the exhaust into the "coolant" that'll bring heat to the engine.

i wish someone would experiment with converting a normal engine into 6stroke with megasquirt
