Definitions

  • Rotary motors offer the following advantages: 1. Absence or reduction of unbalanced forces, since not having parts equipped with alternative movement, spontaneous balancing is easier. 2. Reduction of the number of moving parts, and therefore greater simplicity of production.
  • the invention provides a small motor, free of vibrations, easy to build, high thermal and mechanical performance, always positive torque, physical and chemical treatment of the flame front, quiet, stable and elastic in operation, easy to install in Any, machine that requires it, adaptable to a wide variety of fuels and build it with an extensive range of materials, including composites and ceramics.
  • SUBSTITUTE SHEET (RULE 26) The present project, deals with the development of a rotary internal combustion engine at constant volume (OTTO cycle) perfectly balanced in its driving parts, leaving the sealing vanes as the only alternative parts.
  • the volumes of the chambers formed by the cylinders, vanes and lobes of the rotors are variable, depending on the position in which the rotors are located, the admission and compression phases develop in the first cylindrical vessel, passing the flow of the gases, in the compression phase to the combustion chambers and from these to the second cylinder in the expansion-work and exhaust-sweep phase.
  • the invention provides a thermal machine halfway between the OTTO cycle (reciprocating cylinders and pistons) and the constant pressure turbine system.
  • Combustion starts and develops in an independent chamber, avoiding overloading at the beginning of combustion on the driving parts.
  • the filling of the intake chamber is constant.
  • combustion and the second cylinder to heat liquid or gaseous additives and improve combustion through the flame front that runs through the transfer conduit and reduce harmful gases.
  • the second cylinder can be sized to extend combustion to the maximum performance limit.
  • variable volume chambers of this system six combustions are achieved for every 85 turn of the drive shaft (360 °), and the number of chambers and lobes can be increased and with that the number of combustions for each engine rotation.
  • the operation is uniform, as one or 90 are two expansion chambers in the work phase.
  • the invented engine system is simple to manufacture and maintain, being composed (mostly), of circular parts that are easy to machine.
  • the vanes in their housing act as pumps, for the circulation of the refrigerant.
  • the invention makes it possible to cancel in a vacuum (minimum power) the number of loads and combustions per turn (controlled injection) and as a consequence decrease the fuel consumption.
  • the invention provides for this system the reduction of mechanical noise, by eliminating alternative parts and attenuated expansions in the exhaust, as a consequence of the 120 combustion lengthening.
  • Another advantage is the contribution of catalytic products (liquids or gases), through the transfer conduit supplied by the coil, located 125 both between the combustion chamber and the expansion chamber, in order to increase the molecular mass of the gases of expansion and with it the thermal efficiency of combustion (Hypothesis of Advocate).
  • the first cylinder is constantly in the intake-compression phase, eliminating abrupt cuts in the inertia of the flow of the intake gases and with it
  • Figure 1 is an operating anagram, composed of three phases formed by the elliptical lobes 170, with a separation in the cylinders, joined by the drive shaft and one of the combustion chambers, forming together with the ducts that join it the cylinders
  • Figure 2 is a perspective view of the assembly, with a stator section at 90 °.
  • Figure 3 corresponds to the motor assembly with 180 ° section.
  • Figure 4 is related to the formation of motor pairs in the alternative motors (OTTO cycle) with respect to the system of the invention.
  • Figure 1 shows a simplified diagram of rotary motor operation, which develops the four cycle times, mechanically differs markedly from the alternative motor.
  • the function of the cylinders and pistons is carried out in two vessels
  • the first cylinder (1) houses the elliptical lobular rotor (3) integral to the drive shaft (19) by its
  • the shape of the combustion chambers is spherical (8) to facilitate the advance of the flame front

Abstract

Nouveau modèle de moteur rotatif combustion interne et à volume constant (système marguerite). Ce moteur rotatif représente la forme la plus simple de construction d'une machine thermique rotative pour la transformation de l'énergie chimique des carburants en énergie mécanique et peut s'appliquer à tout type d'ensemble thermique se situant entre les machines alternatives et les turbines, apportant des avantages de ces deux types de machines. Grâce à ce système il est possible d'augmenter le nombre de chambres et de traiter le front de flamme dans sa trajectoire afin de refroidir les gaz résiduels et augmenter leur masse moléculaire afin d'améliorer le rendement thermique et décomposer ces gaz en d'autres gaz moins nocifs. Le couple moteur moyen obtenu est très supérieur à celui de moteurs à piston ou de turbines à gaz en raison de l'absence de mécanisme bielle-manivelle et du fait que les combustions ont lieu dans des chambres. Les rayons moyens de transmission des forces de pression des gaz s'exçerant sur l'arbre moteur sont également plus grands.
