No reciprocation.
Can de stroke itself an be a flywheel storing energy in its own mass.
No Valves.
No Connecting rods to create side loads (therefore rendering rotating liners irrelevant).
Can be configured as a two stroke, 4 stroke, or a compressor, or IVT in wheel drive.
This is running at close to 2000 RPM on 120 PSI compressed air and weighs over 10 pounds (linked u tube video)
Dry sump pressure lubrication with centrifugal return, that stops providing pressure lubrication when in flywheel mode.
Energy storage in the same mass that is the engine block.
Variable displacement.
Variable compression, as high as 50 to 1 eliminating the need for any supercharging.
Automatic timing advance in compression ignition mode that allows timing to be advanced and compression increased when loads are low, eliminating low BSFC altogether.
Throttleless, excess power is stored in the accelerated mass of the engine block, to be transferred to the powertrain, even in flywheel mode with no fuel consumption.
Atomatic pulse a glide operation when combined with an IVT in wheel drive and a hydraulic accumulator. Constant vehicle speed even when cycling engine on and off with no additional driver imput necessary.
Regeneration efficiencies exceeding 80% wheel to wheel. At least twice as efficient as electric regeneration due to minimal number of necessary steps to accomplish regeneration.
Wheel to accumulator, back to wheel.
Light weight and eliminates all conventional powertrain components from the engine flywheel to the brake calipers and rotors, everything between those two components.
