Definitions

  • the present invention relates to an internal combustion engine for a vehicle, and more particularly to a device for enhancing an output of such an internal combustion engine.
  • 3,877,907 discloses an air swirling unit comprising a series of radially extending plates mounted in the interior of a filter of an air cleaner and adapted to make air introduced in the filter form a swirl flow at an inlet of an air intake pipe connected to the air cleaner.
  • the formation of the swirl flow results in an increase in velocity of air flow and thus an increase in air intake amount.
  • air flows radially introduced along the plates strike against one another at the upper portion of air intake pipe, since the plates extend vertically. As a result, it is impossible to promote the velocity of air flow.
  • each guide plate Since each guide plate has an inclined lower end, its air swirling force becomes weak. Moreover, the swirling of air is achieved only in the interior of the air cleaner. As a result, the air flow becomes weak during it passes through a carburetor. This results in an insufficient improvement in engine output obtained by a combustion of fuel and a slow response to a manipulation of an acceleration pedal.
  • U.S. Patent No. 4,274,386 discloses a plurality of inclined air guide plates mounted between a carburetor and an intake manifold.
  • the air guide plates are constructed such that they are twisted to provide a central opening. With this construction, the air guide plates swirl a gaseous mixture introduced in the intake manifold, so as to improve the vaporization of the gaseous mixture and thus increase the combustion efficiency. In this case, however, it is difficult to expect an introduction of air alone at a high density, since the swirling plates swirl the mixture of fuel and air.
  • FIGS. la, lb and 2 there are illustrated other conventional air swirling devices which are disclosed in Korean Patent Publication No. 91- 444. These devices comprise three swirling means attached to an air cleaner, an intake manifold and an inlet of an exhaust manifold, respectively, for exhausting air out of the exhaust manifold in an amount corresponding to the amount of incoming air.
  • the swirling means attached to the exhaust manifold rather serves to shut off the exhausting and thereby attenuate the exhaustion effect. As a result, the output of the engine is reduced.
  • the conventional devices encounter a high possibility that vanes constituting the swirling means may be damaged, because the vanes are made of a flexible material.
  • Korean Utility Model Publication No. 92-4745 discloses a swirling device including a plurality of slitted vanes. By virtue of such a slitted shape of each vane, it is possible to prevent a formation of a negative pressure zone generating a swirl flow, at the rear surface of each vane. As a result, there is a decrease in the resistance of fluid and thus an increase in flow rate.
  • each vane to an outer supporting member becomes weak, since the vane itself is not only comprised of a thin laminate, but also provided with a slitted portion. As a result, the vanes may be broken by a suction force of air, thereby causing the broken pieces to enter the interior of engine.
  • an object of the invention is to eliminate the above-mentioned disadvantages encountered in the prior arts and to provide a device for enhancing an output of an internal combustion engine, which has a simple construction and enables its semi-permanent use, and improves its performance.
  • Another object of the invention is to provide a device for enhancing an output of an internal combustion engine such as a gasoline engine, a LPG engine, a hydrogen engine, an engine of the fuel injection type or the electric ignition type with or without a vaporizer, or a diesel engine, which is capable of enhancing the engine output and reducing interferences upon air intake and exhaust by complete combustion of fuel resulting from an over-supply of a circular fluid at a high density, of maintaining the engine output at a high level even at a high rotation of the engine, achieving a rapid response to a manipulation of an acceleration pedal, economically reducing the ratio of fuel to the running distance, reducing a pollution due to the exhausting gas and preventing an accumulation of impurities such as carbon in the interior of each cylinder, by supplying fuel and air in the cylinder at a high rate and uniformly.

  • FIG. 4 is a sectional view of the air swirling device shown in FIG. 3, in which a flow of air is indicated by arrows. Since each vane 22 has a twisted construction defining the space 23, the incoming air or fluid proceeds rapidly in circular, by virtue of the twisted angle of each vane. The velocity of the circular air flow is increased by the functions of two swirling plates 20 and 20' arranged to define the predetermined space therebetween. On the other hand, introduction of air or fluid is also achieved through the openings 21 which are formed at the center portions of swirling plates 20 and 20', respectively. The air or fluid flow passing through the central openings 21 proceeds straightly, without any interference.
  • the fluid impinging against each twisted vane 22 generates a swirl flow at the central portion of cylindrical body 10 while proceeding rapidly in circular along the inner wall of cylindrical body 10.
  • the swirl flow sucks and interferes with the circular high density fluid flow proceeding at a high velocity, so that it can not proceed toward the intake manifold.
  • the straight fluid flow passing through the openings 21 serves to guide the circular high density fluid toward the intake manifold, by virtue of its straight propulsion force. Accordingly, the flow rate is increased, as compared with the conventional construction including vanes (air sucking vanes) with an angle approximately corresponding to the proceeding direction of fluid.

  • the peripheral edge of each vane 120 is firmly attached to the inner wall of the cylindrical body 100.
  • the cover 110 also serves to concentrate a flow of air introduced in the interior of body 100 at the vanes 120.

Abstract

Un dispositif, destiné à augmenter la puissance du moteur à combustion interne d'un véhicule, comprend un corps (10), installé sélectivement devant le carburateur ou à l'entrée d'un collecteur d'admision du véhicule, et une plaque tourbillonnaire (20, 20') réalisée en un matériau stratifié mince et rigide et pliée de façon à engendrer un flux tourbillonnaire grâce à plusieurs aubes (22). Celles-ci font tourbillonner rapidement un fluide introduit dans une ouverture centrale (21) destinée à aspirer vers l'intérieur du corps (10) le fluide que la pression ainsi exercée fait s'écouler directement le long de l'axe central dudit corps (10). La plaque tourbillonnaire (20, 20') fait tourbillonner la partie du fluide qui est introduite le long de la paroi périphérique du corps (10) tout en accélérant la vitesse de ce fluide grâce à la pression exercée par le fluide passant directement au travers de l'ouverture centrale (21). Ainsi est-il possible d'obtenir une réaction très précise au déplacement de la pédale de l'accélérateur et donc de fournir rapidement un mélange air-carburant présentant un rapport approprié aux conditions d'utilisation. On peut alors obtenir une combustion complète, ce qui accroît le rendement de ce moteur à combustion interne.
