Seems kosher to me. They're just claiming efficiency improvements from design, not trying to repeal the Second Law of Thermodynamics. Whether the
engine actually works as advertised is another question.

there are other designs out too... such as that circular-piston design (forgot the name) where the pistons are arranged in a circular pattern instead
of the usual line, V or W... and if I remember correctly, they fire AROUND the engine, instead of in and out...
Well, there's the Wankel rotary engine, but that doesn't have pistons, it has a rotor on a central shaft and spark plugs arranged around the rim of
the combustion chamber that fire in sequence to keep the rotor turning. NSU and Mazda both had successful production cars fitted with Wankel engines.
Maybe other companies did too.
Then there's the radial
engine, in which the pistons are arranged in a circle around the driveshaft. They were popular with aircraft designers
in the propeller era because they eliminated some issues (torque or vibration if I recall correctly) that caused handling problems in aircraft. Now
entirely outdated, I fear.
