Definitions

  • the present invention describes the improvement of a heat engine that can be designed like a motor, achieving optimal performance, almost completely eliminating mechanical friction and improving the thermodynamic cycle. It involves eliminating the buffing forces that occur between the stator and the pistons, allowing practical functioning and guaranteeing effectiveness, obtaining a compact assembly, without vibrations, of great specific output and low mechanical complexity.
  • this design also has the compression ratio of the traditional piston engines, good geometry of the combustion chambers and in addition, it produces 4 times as many explosions per crankshaft turn as the Wankel engine.
  • the invention involves calculating a law of motion of the oscillating pistons whose centers turn at the end of some cranks (and whose ends follow a contour, creating variable volumes) and in being able to produce this motion with simple and easily attainable internal mechanisms in practice.
  • the absence of these devices would force the stator to drive the pistons.
  • the latter when being subjected to large angular accelerations, would need a very large outer couple/torque that would wear the material quickly and would hinder performance.
  • the desired goal is to eliminate friction between the piston and the stator of thermodynamic rotary engines composed by cranks and oscillating pistons.
  • the system the present invention patent is made up of one or various sets consisting of:
  • the present invention aims to achieve that the centers of curvature of the piston ends follow the theoretical contour of the stator, this being obtained by an internal mechanism from the cranks, which means that even in the absence of the stator the piston would be forced to carry on moving in the same way.
  • the piston ends do not touch the stator, only the segments protrude until closure takes place. In this way, absence of important friction is guaranteed, which would otherwise occur, given the need to accelerate the pistons angularly due to a lack homogenous pressure on the initial explosion.
  • the piston pivots with the first crank which is connected to the crankshaft and also plays the role of the connecting rod of a traditional engine.
  • the assembly formed by the two or four pistons given its symmetry, achieves total balance (as opposed to only first order balance obtained in the majority of piston-driven engines), and this noticeably increases the thermodynamic cycle (the zone corresponding to entry stays cooler than that of combustion, the position corresponding to ignition lasts longer, improving combustion, and the combustion chamber is sculpted, giving it a more favorable shape).
  • Another interesting characteristic is the reduced size of the assembly, diminishing the size as compared to a conventional engine by nearly 50 %. To all these advantages one must add the great improvement in mechanical performance, on having eliminated inertial friction and the longer-lasting frontal segments in comparison with the Wankel motor, given the more regular shape of the stator (without sign change of the curvature radius for values of g below 1/3 ).
  • An angular position of the axis (14) determines the positions of the two cranks, connected to it by means of a double-cardan joint, thus the position of the piston remains fully determined.
  • Secondary double crank (3) joined by a secondary axis (4) concentric to the main axis Fig.1 and Fig.2 .
