It would be cool to see a steam-ICE-elecyric motor hybrid that uses engine block heat for the steam, and electric current generated by the combustive processes are harnessed, maybe by using a conductive cylinder sleeve. Speaking of, why don't we use cylinder sleeves anymore? Modern machining is more precise.
The power grid...
>>16935685turbo chargers and regenerative braking already recycle things really well.>why don't we use cylinder sleeves anymore?you can but they are pointless without properly skilled labor. it's cheaper for everyone to just accept wear and tear on the engine block, so it ends up only being a specialty performance enhancement.
>>16935685>uses engine block heat for the steamA 6-stroke engine does this, the last two strokes is water injection followed by steam expansion, and then pushing the steam out. That steam still has some thermal energy and you can harvest quite a bit with a steam turbine.The gives you 2 power strokes out of 6 strokes, compared to 1 power stroke out of 4 strokes and avoids water cooling, at the expense of significant added complexity.
>>16935685You would need to purchase distilled water and refill it regularly. Distilled water isn't cheap and tap water will quickly foul your engine with deposited minerals.
>>16935685The truth is that a steam engine with a closed water loop would be water better than normal ICE engines
>>16936385Could a vortex tube condense water from the exhaust gasses? I remember reading a Russian paper where they extracted water from steam using this tube.
>>16936385>You would need to purchase distilled waterDid steam engines of the past rely on destilled water?Doubt.>>16936951Perhaps though it is not clear how much loss the back pressure would cause.
>>16935877when an engine is to be rebuilt they can be sleeved once the cylinder is bored out, some have to be sleeved during a rebuild because the cylinder walls would be too thin after boring
