A piston combustion engine design principle that avoids the strong sidewall friction of conventional combustion engines. while it requires precision engineering and is subject to thermal expansion issues, an alloy such as Invar 36% nickel in iron has exceptionally low thermal expansion and can easily make the design work without the conventional piston rings. because it is not friction based it can thus run without lubrication making the design simpler and much more energy efficient. the rocker arm will link to a crank shaft as normal.

  • so how does this piston produce torqure? i just see it going up and down is there going to be a ratcheting device at the end of the arm?

  • @fuelinjectedmaniac says so in the description. valves are also missing. that could be a rotating cylinder on its side on top of the cylinder, again more efficient than existing engines.

  • What's wrong with a good rotary engine anyway? :) There are a number of things still lacking in the design concept not yet shown, valves, spark plug, oil control/compression rings. The thickness of the top of the piston doesn't look sufficient to take the stresses of combustion over time.

  • @shades2 obviously a lot of details missing. just to illustrate the key innovation.

    I imagine a revolving valve head for similarly better efficiency.

    rotary engines are notoriously inefficient. and problematic.

    but it increasingly becomes a moot point. pure battery electric drive will own for personal transport.

  • @DanFrederiksen what? rotating cylinder? based on what math is this more efficent then modern motors? how would you propose to get a precsion machined surface shaped like that in a block?

  • @shades2 integrate into the preexisting infrasturcture that already exists, hydrogen already shows promise for a better fuel solution if it can be procured in a great enough amount, mercedes went around the world with their f class hydrogen cars and made it through some pretty barren places you wont see an electric car do that

  • @shades2 battery technology has a long way to go before it is ever practical for everyone sure a hybrid or electric car is okay for a daily driver with a city commute but an electric car requires 12 hours to charge completely and living out in the country with a dead battery with no source of energy besides gasoline isn't going to cut it for remote areas battery powered vehicles won't cut it hydrogen or a next gen fuel is the more practical solution and would better integrate

  • @DanFrederiksen I think hybrids will dominate first, but ultimately battery/electric cars will take over, and later on perhaps for heavier vehicles like trucks.

    Such a radical change, will change a lot of corporate businesses. Fuel stations, mechanics, engine manufacturers and component makers. Most will be obsolete or have to completely change tack.

  • @p930racer you dont sound like an engineer at all you sound like a 16 or 17 year old kid that tinks he knows p930 and you didnt work on aerospace stuff or youd realize a millionth of an inch or a mill is possible

  • @p930racer and its not hard you just have to control the temperature of the metal and have a VERY expensive mill the metal is always on a chiller or heater and the room i mill in is temperature controlled so their is no thermal expansion or contraction or the metal when im cutting i have to take off a millionth at a time to not heat the bit and let it cool so i know im cutting right again accounting for thermal expansion its really quite complicated im not surprised if your mind cant comprehend
