Definitions

  • VACUUM COMPENSATOR FOR EXPLOSION ENGINES - OBJECT OF THE INVENTION consists of a vacuum compensator for explosion engines, which is useful for compensating the vacuum cuts caused in the intake manifolds of the explosion engines, produced with violent accelerations of the rotation regimes of the same, which causes that there are "peaks" of fuel consumption (gasoline, diesel, etc.), due to chemical contact defects between the fuel (diffused or injected), and the oxidizer (oxygen, normally supplied by air).
  • the vacuum compensator is constituted by a non-hermetic valve, defined by a hollow cylindrical body opened by one of its bases and endowed on its other base with a body of flexible material, integral perimeter to the lateral surface thereof and centrally provided with a circular hole, as well as radial cuts that define several circular sectors, the vacuum compensator being installed as a closure of the suction opening of the box containing the engine air filter.
  • the vacuum compensator as a closing of the suction opening of the box containing the air filter of the explosion engines, it is achieved that before a sharp acceleration, the time in which there is a momentary decrease in The depression available in the intake manifold decreases without an increase in CO production.
  • the great advantage that is obtained is that with the incorporation of the vacuum compensator in the explosion engines, the fuel consumption is reduced, with the consequent economic savings that this represents.
  • the vacuum compensator described herein is useful for installation in the explosion engines so that with it, in the event of a sharp acceleration, the time during which the depression of the depression of which it is momentarily decreases is reduced available in the intake manifold, reducing the "peaks" of fuel consumption and consequently obtaining economic savings.
  • a particular application is in motor vehicles with the great advantage that reducing fuel consumption represents an economic saving for the user.
  • the vacuum compensator is intended to act at the moment that the explosion engine is in a situation of combustion of low energy efficiency, so that this situation occurs when the engine demands a greater transfer or contribution of energy, that is , at the moment the accelerator that opens the throttle valve of the intake manifold is pressed, so that a momentary decrease in the depression available in the engine is usually observed in any engine and to a greater or lesser extent intake manifold.
  • the objective to be achieved is that the time in which the vacuum cut occurs in the intake manifolds of the explosion engines when making sharp accelerations in the rotation regimes thereof is reduced, to reduce or eliminate the "peaks" of fuel consumption and thereby save money.
  • This report describes a vacuum compensator for injection engines of special application in motor vehicles which is mounted in the intake opening of the outside air, to the air filter location box, so that the It presents a general hollow cylindrical shape with one of its bases open and arranged in its other base of a body of flexible material, fixed perimetrically to its lateral surface and being provided with a circular central opening, of radial cuts that define a series of circular sectors identical to each other.
  • the nature of the flexible material body, arranged on a base of the hollow cylindrical body that defines the vacuum compensator, as well as the diameter of its central opening and the number of radial cuts, will be determined based on the characteristics of the motor.
  • the hollow cylindrical body that defines the vacuum compensator will have a maximum height of 10 cm. and its inner diameter will be equal to or greater than the diameter of the suction opening of the air filter housing in which it is mounted, and the anchor can be made by any conventional means, such as a flange.
  • the appropriate reduction cylinders shall be arranged to adjust them as closely as possible to the diameter of the opening of the suction tube.
  • the circular sectors that define the body of flexible material attached to a vacuum compensator base are in continuous movement, opening and closing, between two extreme positions, so that in the combustion situation of maximum energy efficiency, the circular sectors they are flexed, in relation to their connection to the hollow cylindrical body, their free ends remaining in the part of maximum distance from each other, while in the combustion situation of low energy efficiency, the circular sectors will remain in their resting position with its free ends in the closest situation to each other, decreasing the air inlet section, and increasing the penetration rate of the latter throughout the entire intake system.
  • Figure 1 Shows a schematic view of the assembly of the vacuum compensator, arranged in the outside air inlet to the air filter location box.
  • Figure 2 It shows a perspective view of the vacuum compensator, defined by a hollow cylindrical body provided with an open base, and the other base provided with a body of flexible material perimetrially welded and centrally presenting a circular hole from which a series starts of radial cuts that define circular sectors.
  • Figure 3 Shows a plan view of the vacuum compensator defined by a hollow cylindrical body, in relation to its base provided with the flexible material body, being able to observe the central hole itself, as well as the radial cuts that make up the circular sectors of the same.
  • Figure 4. Shows a side elevation view of the vacuum compensator defined by a hollow cylindrical body.
  • Figure 5. It shows a perspective view of the vacuum compensator, in relation to the base of the hollow cylindrical body that forms it, which is provided with the flexible material body provided with a central hole and radial cuts, observing the same in the position in which the free ends of the circular sectors of the flexible material body are at the point of maximum distance between them, having said circular sectors flexed in relation to the base of attachment to the hollow cylindrical body.
  • the vacuum compensator 1 defined by a hollow cylindrical body, is mounted in the air inlet mouth outside the box 2 in the that the air filter is located, being fixed in this case by means of a flange 3, although the fixing device may vary by any other conventional.
  • Figure 1 of the designs shows the assembly and installation of the vacuum compensator 1, as well as the cylinder head 4 of the engine and the intake manifold 5, attached to the flowmeter 6 air meter by means of a rubber tube 7 with the bellows ends with the flowmeter remaining at the outlet of box 2 in which the air filter is located.
  • Vacuum compensator 1 constitutes a non-hermetic, fast-acting valve, being applied to compensate for vacuum cuts, produced with violent accelerations of the rotation regimes in the explosion engines, caused in the intake manifolds of the same, which produces "peaks" of fuel consumption (gasoline, diesel, etc.), due to a defect in chemical contact between the fuel (diffused or injected) and the oxidizer (oxygen normally supplied by air).
  • the vacuum compensator 1 is defined by a hollow cylindrical body with one of its bases open to allow free passage of the oxidizer, in the most frequent case air, and the other base has a body 8 of flexible material , joined perimeter to the lateral surface of the body 1 which has a small circular central opening 9, from which a series of radial cuts 10 are formed that form a series of bodies in the form of a circular sector, in the body 8 of flexible material , all of them in the same way.
  • the central opening 9 of the body 8 of flexible material will be of varying diameter depending on the cubic capacity of the engine, as well as the nature of the flexible material of the body 8, and the number of circular sectors defined by the radial cuts 10 will be defined by the characteristics of stroke, diameter, maximum power and number of valves per cylinder and system of feeding of the engine on which it is going to be applied.
  • the inside diameter of the cylindrical body that defines the vacuum compensator 1 will never be smaller than the diameter of the suction opening of the box 2 containing the air filter in which it is installed, preventing the height of the cylinder of the valve is greater than 10 cm. If, for different reasons, the body 1 should exceed that length, models intended for larger displacement engines in which larger diameter vacuum compensators are installed must be chosen, using the necessary reduction cylinders for installation to reach the approximate diameter of the original opening of the engine air filter box 2.
  • the air intake section decreases, increasing its penetration speed throughout the entire intake system and to the very center of the explosion chambers, restoring therefore and in surprisingly short time, the vacuum generated by the engine in the intake, so that the maximum increase in pressure inside the manifold drops by an average value of 20% depending on the engine to which it is applied, keeping it " peak "pressure for a shorter time than the vacuum compensator does not exist.
