Seems Boyeson (the company who brought us two-stage digestible fiberglass intake reeds more than 20 years ago) have been burning the midnight oil.
Pictured is a weird looking 2-stroke engine equipped with a lever not unlike those used to power a steam engine.
The lever is moved by a crankshaft eccentric to open and close an exhaust valve guillotine every stroke of the engine.
Boyeson claims this action delivers amazing, 4-stroke-like torque, incredible fuel economy and dramatically reduced emissions without direct injection.
Clearly, the patented concept was on display to attract OEM attention and a potential patent sale. Stay tuned!
