DOT versus Crank and Rod Mechanism DOT transforms directly Rotary Motion to Rotary Motion DOT has a Unique, Perfectly Straight and Robust Drive Shaft DOT connects ANY Required Number Bodies in Strictly ONE Plane DOT performs ANY Kinematic Pattern THE DOT versus Reciprocating Piston Engine THE DOT has almost Three Times Fewer Moving Bodies THE DOT has a Sealing of the Same or even Better (VORUS) Quality THE DOT has an Application of All Forces in Strictly One Plane THE DOT has an Incomparably Smoother Operation THE DOT versus Opposed Pistons Opposed Cylinders Engine THE DOT has mathematically DOUBLE the Working Volume for the same Total Volume and Weight THE DOT has an Incomparably Smoother Operation THE DOT versus Napier Deltic Engine THE DOT has Three only Pistons arranged in Three variable (in a rolling way) Couples, instead of Six Pistons arranged in Three permanent Couples of Napier Deltic Engine THE DOT has an Incomparably Smoother Operation THE DOT versus Revetec Engine THE DOT has a Fluctuation of Pressure Angle, for any of its Transmission Pairs, of less than ± 5 Degrees about the Optimum Value, while this Fluctuation expands to even ± 60 Degrees for the Revetec Engine THE DOT has a Smoother Operation THE DOT versus All Lobe Rotor Type Engines (Wankel Engine with Solid Rotor, QuasiTurbine with Articulated Rotor, etc) THE DOT has a Sealing of Incomparably Better Quality THE DOT achieves an Incomparably Higher Compression Ratio THE DOT has an Efficient Area on Piston Face for Gases Forces THE DOT has an Efficient Lever Arm for Torque Production on Drive Shaft THE DOT versus All "Cat-and-Mouse" Type Engines (Virmel, Kauertz, Tschudi, Trochilic, Oscillating Piston, Rotary Opposed Piston, Massive Yet Tiny, etc) THE DOT has ANY Required Number of Groups of Pistons, instead of ONLY Two of All "Cat-and-Mouse" Type Engines THE DOT has a certain Direction of Cycle Propagation THE DOT has a Sealing of Incomparably Better Quality THE DOT has an Incomparably Smoother Operation THE DOT versus All Known Volume Variation Engines THE DOT performs Perfectly ANY Required, even IDEAL, ThermoDynamic or HydroDynamic or Refrigeration Cycle, or a Combination of these THE DOT has the Highest Efficiency and the Highest Power Density |
