Has anybody see the new piston design for the 2 stroke engine?
Basically some clever cat worked out that the wrist-pin area of the 2 stroke piston acts as a type of transfer port and he has developed a piston with no wrist-pin hole. The piston is made in two parts where the wrist-pin part, together with the connecting rod, is screwed into the piston from underneath.
Unintentionally this design lightened the piston and made it rounder which gives it a better seal and virtually eliminates the rubbing of the skirt on the barrel as the piston no longer rocks. The main goal is achieved which is the eradicating of the losses through the wrist-pin area of the piston.
I'm in awe of the simplicity of this design which will, in my opinion, revolutionize the 2 stroke engine.
