Definitions

  • the invention is comprised in the technical sector dedicated to internal heat combustion engines, more specifically those called explosion or spark ignition engines (SIE).
  • SIE explosion or spark ignition engines
  • Pistons and connecting rods, as well as reciprocating motions making the balancing of the engine more difficult in order to prevent vibrations, are avoided with the present invention in which the rotor is directly coupled to a crankshaft.
  • Patent document DE 103 48 294 A1 describes a rotary engine similar to that of the invention but having different stator and rotor profiles and a different configuration for the distribution and feed system.
  • the present invention relates to a hypocycloid rotary heat engine of the type referred to as an explosion or spark ignition engine (SIE).
  • SIE explosion or spark ignition engine
  • It comprises a curvilinear triangular shaped fixed body or stator with three chambers and planar covers, inside which chambers there is a rotor coupled to a crankshaft, the rotor maintaining permanent contact with the covers and with the profile of the stator in order to achieve tightness between these elements.
  • the rotor twice as long as it is wide and with circular ends, is assembled in the crank pin of the crankshaft to which it transmits its circular orbital motion.
  • a combustion or explosion chamber there is another small auxiliary chamber in the peripheral part of each of the chambers, referred to as a combustion or explosion chamber, where the sparkplug is included and which also communicates with the rotary valve.
  • the rotary valves which perform the dual intake/exhaust function, are tubular, penetrating the air and fuel mixture at one of their ends when the intake stroke is carried out and the burned gases exiting at the other end after expansion to carry out the exhaust stroke.
  • the operating cycle of the engine has four strokes or phases: intake, compression, explosion-expansion and exhaust.
  • the complete cycle is carried out in a single turn of the rotor corresponding to two turns of the crankshaft.
  • the fuel to be used can be liquid or gas, in each case varying the fuel injection feed system to obtain suitable explosive mixtures.
  • This type of engine can be applied in different fields, such as automotion in general, generating energy and driving industrial and farm equipment.
  • the present invention thus has a series of advantages over the state of the art:
  • the rotating and at the same time circular orbital motion of the rotor is identical to that of a hypocycloid gear within the stator acting as a crown-wheel; obtaining as a favorable result that the angular and orbital velocities of the rotor are maintained constant for each rate of rotation of the crankshaft.
  • Figure 9 shows a section view of an engine of the invention.
  • stator In order to make an engine prototype, the stator, its closing covers, the rotor and the valves are to be made of alloy steel, similar to that which is used for cylinders in reciprocating engines, machining fine finishes in the surfaces in contact with the rotor and the valves.
  • a cut has been made at each of the ends of the rotor and such ends have been closed with straight segments to ensure the tightness with the stator to absorb the thermal expansions in the rotor; said cuts and segments have not been described in the drawings to simplify and improve the understanding thereof.
  • the coupling with the crankshaft has been provided with bearings.
  • crankshaft also made of alloy steel suitable for these types of parts, must be constructed in at least two halves in order to be able to assemble the rotor.
  • the driving force caused by the engine will be taken from one end of the crankshaft and the other end will move by means of gear-tooth belts and pulleys, the rotary valves, as well as the necessary auxiliary elements for adapting the chosen ignition and fuel injection systems on the market.
  • Lubrication can be carried out by means of an oil circulating pump with a crankcase.
  • the engine of the invention further comprises a combustion chamber (a, b, c): in communication with each lobe of the internal cavity (A, B, C) through the inner periphery (PI); having:
  • the combustion chamber (a, b, c) is located in a vertex of the lobed triangular shape.
  • the exhaust means are formed by a rotary circular valve (Va, Vb, Vc) having: a circular intake segment (SA) having an intake arc (AA) for allowing a reactant to enter from an intake manifold into the combustion chamber (a, b, c); and a circular exhaust segment (SE) having an exhaust arc (AE) for allowing an exhaust gas outlet from the combustion chamber (a, b, c) to an exhaust manifold; wherein:
  • the engine further comprises:
  • Any engine additionally comprises:
  • the stator further comprises a plurality of cooling lines (G) for circulating coolant fluid located between an inner wall (IW) rounding the inner periphery (PI) and an outer wall (OW) defining the outer contour of the engine.
  • G cooling lines
  • the engine also comprises:
