STRANGEST Engine PART Ever MADE

Ғылым және технология

the Coates Spherical Rotary Valve System creates "a quieter engine with higher specific power output and longer life than conventional poppet valve engines due to better 'breathing' capability and higher speed capability. Is this the real deal or has it succumbed to reliability problem.

    I can't say that it definitely does, but it stands to reason. Consider the number of points where it's gotta seal, the precision of that joint and its relation to every other joint on that head, the fact that you have made every last sealing surface nonplanar and curvilinear, and the fact tlat, unlike a tappet valve, the pressure of the cylinder is gonna try to blow this little monster open instead of hold it shut... you've eliminated the camshaft, but you're making the cylinder head and valvetrain three or four times more expensive and prone to failure, and impossible to reliably fix without a CNC machine. You'd be better off trying sleeve valves again.

    @@jeremylakenes6859 Cylinder temperatures at the end of the commpression stroke are directly proportional to the dynamic compression ratio of an engine. The valves on this engine leak, so although the static compression ratio is high, part of the charge escapes, lowering dynamic compression ratio. Just like the wankel engine, this engine is an excellent idea. However, just like the wankel engine, it has unsolvable flaws. Take a wankel rotor, turn it on its side and you'll realize you're trying to seal a rectangular piston. Look at a coates cylinder head from up close and you'll realise you're trrying to seal a ball valve at high speed, temperature and pressure. For it to work as well as poppet valves, the rotating valves would have to be forced against the cylinder head by combustion, not away from it.

    IIRC, the big two biggest problems were sealing against combustion pressure and lubrication of the "valves", but in the long term the valves ate away at the necessarily tight clearances with the cylinder head to the point of allowing spent gases into the intake tracts, eventually stopping the engine altogether. Poppet valves have proven to be the only demonstrably reliable setup for well over a century.

    Any timing issue would be solved by a hydraulically advanced timing gear. I think it was Nissan who first utilized this on the 300 Z. At a given RPM a valve was activated on the oil pressure line diverting oil in the timing gear allowing the gear to advance say above 3000 or 4000 rpms. This allowed good torque at low rpm's and higher horsepower at higher rpm's and higher revs.

At the end of the project one of the engineers put the motor in a boat that went too fast and sank due to the flywheel effect of the motor ripping itself off the mounts when the driver tried to turn the boat sharply around.

    Fiat MultiAir is one of the best ideas. The cam drives hydraulic pistons which use oil pressure to open the valve. Oil is bled off to control valve lift and duration. There is no need gif s throttle valve but you can’t us the valve controls to start the engine.

    I designed a rotary valve camshaft cylinder head, with no springs you can achieve high rpm with less parasitic losses

    If you need patent it unless it's already out there (then you're screwed), and then share it. There is also a design of patent known as a poor man's patent you can use. They have some ways to look up preexisting patents also

    If you only ran air through the valves and directly injected something like propane or natural gas it would work and have less fouling and carbon problems.

    I would think that because combustion is happening INSIDE the valves, you would have problems with those valves expanding and contracting due to internal heat.

    Willis Overland had rotary sleeve valves on the streets in the late 1920s. Not a complete match mechanically to these, but functionally almost identical. They worked pretty well considering the poor quality fuel and oil they had to run on.
