I wanna see a completed engine using this design. The very high rod anlge on the upstroke would just increase friction on both upstrokes, and now the cylinder in question doesn't have the force of combustion to help overcome this friction(as it would on a standard design), so it must rely on another cylinder to help out. It may work, but I'm skeptical. If it were that easy, why are we still using ancient designs?
