1.       Piston and piston ring must be slide in the cylinder with a minimum of friction loss. 2.      Piston and piston ring must have enough to take the punishing pressures and temperatures of the combustion process. 3.      Piston and piston ring must be minimum weight so as to keep inertia losses down. 4.      Piston and piston ring must be a cross section sufficiently large to provide an adequate heat path so excessive piston head temperatures will not occur. 5.      They must be able to exercise adequate oil control. 6.      Piston and piston ring must be minimum clearance with the cylinder wall so as to minimize blow by. 7.      Piston and piston ring must change in size and shape very little as a result of temperature changes. 8.      Piston and piston ring resist...
