Definitions

  • the present invention relates to an apparatus for saving fuel and cleansing the exhaust gas in a multicylinder vehicle engine having at least one intake manifold with a carburetor means and a plurality of branches communicating engine cylinderinlets with the manifold.
  • the reason for incomplete combustion of the supply gas mixture in the combustion chamber during coasting is due to the fact that the intake amount of air in the supply gas mixture decreases and a large amount of residual gas stays in the combustion chamber during the coasting, so that either ignition fails or the barely ignited combustion dies out without spreading through the combustion chamber;
  • This is one of the problems related to the fundamental structure of 'intemal combustion engines, and the only way to effectively burn the supply gas mixture in the combustion chamber under such conditions is to increase the intake amount of the supply gas mixture to the combustion chamber.
  • a known method of preventing air contamination is to retard the spark advance during idling, and to keep the enginerevolving speed at a comparatively high level, so as to improve the fuel combustion in the combustion chamber as far as possible.
  • the idling throttle valve opening is increased to allow a large intake amount of the supply gas mixture during the deceleration.
  • such niethod has a disadvantage in that the throttle valve cannot be opened widely due to the danger of overheating and the occurrence of run-on phenomenon.
  • An object of the present invention is to obviate the aforesaid difficulties of the known air contamination preventing devices, by providing an improved device for effectively preventing the air contamination and at the same time reducing the fuel consumption.
  • the operative principles of the device according to the present invention are as follows.
  • Another object of the present invention is to fulfill the function of preventing air contamination without sacrificing the effectiveness of the engine-braking action, as experienced in the case of known device controlling the negative pressure at the intake manifold, and without causing any mechanical shocks as experienced with a known device limiting fuel shut off.
  • FIG. 1 is a partial sectional plan view of the inlet pipe of a four-cylinder-type engine with a device according to the present invention, shown with a carburetor removed therefrom;
  • FIG. 2 is a schematic composite vertical sectional view, prepared by combining a section at the line [HI and another section at the line II-Il of FIG. 1;
  • FIGS. I and 2 a carburetor 1, having venturies 2 and throttle valves 3, is connected to an intake manifold 4 with branches 5, 6, 7, and 8.
  • FIG. 1 illustrates .an engine with four cylinders, but the number of cylinders is not limited to four, but any other number of plural cylinders can be used.
  • the dash-dot lines 9 of FIG. 2 represent a cylinder head.
  • butterfly valves 10 are mounted on branches 6 and 7, in such a manner that the butterfly valves are rotatable around the shafts 11 secured to the intake manifold across the branches.
  • An arm 12 is secured to the shaft 11.
  • one end of a pipe 13 is connected to open in the wall of the intake manifold 4 at a position of upstream of the butterfly valves 10, and the opposite end of the pipe I3 is communicated with a cylinder 15 having a piston 14 slidably fitted therein.
  • the piston 14 has a hollow chamber 14a formed inside thereof and communicated with the pipe 13, throughholes 14b communicating the hollow chamber to the outside of the piston 14, and an annular recess 14c formed on the outer periphery of the piston 14.
  • the cylinder 15 has an annularrecess formed on the inner peripheral surface thereof.
  • a port 16 is bored at the bottom of the annular recess 150 so as to communicate the inside of the cylinder 15 with another cylinder 20 to be described later.
  • the cylinder 15 has an additional opening 17 bored in the proximity of the annular recess 150, a stop ring 18 fitted on the inner surface of the cylinder 15 at the right-hand end thereof for stopping the piston 14, and a spring 19 fitted between the left-hand end of the cylinder 15 and the left-hand end of the piston I4, as shown in FIG. 2.
  • the cylinder 20 is connected to the aforesaid cylinder IS in such a manner that the port 16 communicates with the two cylinders 15 and 20.
  • a piston 21 slidably fitted in said other cylinder 20 has a piston rod 22, which is connected to the free end of said arm through a link 23.
  • a spring 24 is engaged with the arm 12 to force the arm 12 to a counterclockwise direction and the link 23 downwards, as seen in FIG. 2.
  • the branches 6, 7 have holes 25 bored thereon at positions between the respective butterfly valves 10 and the cylinder I head 9.
  • the holes 25 of the branches 6 and 7 are communicated with each other through a tube 26.
  • a short open tube 27 is connected to the tube 26 so as to communicatethe inside of the tube 16 with the atmosphere.
  • a valve lever 28 is pivotally supported by the branch passage portion 7 by means of a pin 29, to selectively close and open the upper end opening-of the open tube 27.
  • a projection 30 is secured to the piston rod 22 in such a manner that when the butterfly valve 10 is closed, the projection 30 raises the free end of the valve lever 28 to open the upper end opening of the tube 27.
  • a packing 31 is mounted on that portion of the valve lever 28 where the hole 27 engages the valve lever 28, and a spring 32 engages the valve lever 28 so as to bias the valve lever 28 toward the lowered position, as seen in FIG. 2, for keeping the open tube 27 closed.
  • FIGS. 1 and 2 illustrate-the device under the conditions when the automobile is neither decelerating nor coasting.
  • the thus increased negative pressure at the intake manifold is delivered to the space A, so as to pull up the piston 21.
  • the arm 12 rotates clockwise, as shown by the arrow B in FIG. 2, through the piston rod 22 and the link 23, so as to close the butterfly valves 10, as shown by dash-dot lines.
  • the supply gas mixture is absorbed only by the cylinder branches 5 and 8 having no butterfly valves 10, so that the amount of the supply gas mixture to the branches 5 and 8 is considerably increased and the combustion conditions in the engine is greatly improved.
  • the downstream side space of the butterfly valves 10 is communicatable with the atmosphere through the holes 25, the tube 26, and the short open tube 26 blockable by the valve lever 28.
  • the projection 30 secured to the piston rod 22 connected to the piston 21 engages the free end of the valve lever 28 upon the closure of the butterfly valve 10, so that the valve lever 28 turns clockwise against the elasticity of the spring 32, as seen in FIG. 2, to deblock the short tube 27.
  • the atmospheric pressure enters into the back of the butterfly valves 10 through the short tube 27, the tube 26, and the holes 25.
  • the pressure at the back of the butterfly valves 10 increases to insure the complete interruption of the supply gas mixture by stopping the leakage through fine gaps around outer periphery of the butterfly valves 10. Furthermore, the air delivered to the back of the butterfly valves 10 through the holes 25 proceeds to the exhaust tube and acts to oxidize the incompletely burnt hydrocarbons contained in the exhaust gas to convert them into hannless carbon dioxide gas. Thereby, the cleansing effect of the exhaust gas is further improved.
  • FIG. 3 shows another embodiment of the device according to the present invention, in which an electric control means is incorporated.
  • the electric control means comprises a vacuum switch 33 to sense the negative pressure at the intake manifold of an automobile engine, a solenoid valve 34 whose solenoid is connected in series with said vacuum switch 33, power source batteries BT connected in series with the series-connected vacuum switch 33 and the solenoid valve 34, and a manual switch 35 connected across the vacuum switch 33.
  • the performance characteristics of the vacuum switch 33 is such that when the automobile is decelerated to reduce the negative pressure at the engine intake manifold, a diaphragm 36 is deflected downwards against the elasticity of a spring 37, as seen in FIG.
  • the operation of the solenoid valve 34 is controlled by the vacuum switch 33, but the actuator of the solenoid valve in the device of the invention is not limited to only such vacuum switch.
  • an accelerator switch, a clutch switch, and a gear neutral switch can be connected in series, so that the solenoid valve can be actuated only when i.e. accelerator is not stepped down while connecting the clutch with the gear at any position other than neutral position.
  • FIG. 4 shows another embodiment of the present invention, using three electric switches, i.e. a clutch switch 46, an accelerator switch 47, and a gear neutral switch48, for the purpose of detecting the coasting operation of an automobile.
  • FIG. 5 shows an electric switch 'usable in the embodiment of FIG. 4, which comprises brushes 49, 52, a push rod 51 made of electric insulating material, an electric conductor member 50 secured to the push rod 51, a bias spring 54, and terminals B and C.
  • the solenoid valve can be actuated through such switches. More particularly, in FIG. 4, when an automobile runs in coasting mode, a circuit is completed, which traces from one terminal of the power source BT through switches 46, 47, 48, and the solenoid valve 34, and back to the opposite terminal of the power source BT.
  • the solenoid 40 acts to pull an armature 41 rightwards against the elasticity of a spring 42 to communicate a pipe 13 to the space A above a piston 21, in the same manner as the preceding embodiment described hereinbefore referring to FIG. 3.
  • the right-hand end 44 'of the armature 41 blocks an opening 45 communicating the inside of the solenoid valve to the outside atmosphere.
  • the manual switch 35 in the circuit of FIG. 3 or FIG. 4 can be closed to improve the fuel consumption in a multicylinder engine during low speed running by actuating only a part of the multicylinders. More particularly, with the switch 35 thus closed, the supply gas mixture delivered to nonvalved cylinders burns well, while those valved cylinders do not receive any supply gas mixture at all, and hence, the overall fuel combustion rate is improved. Thus, the fuel consumption can be improved.
  • a perfect balance of engine can be maintained by interrupting the intake of the supply gas mixture to the fourth, fifth, and sixth cylinders.
  • the extent of the interrupting of the intake of the supply gas mixture is not limited to one half of all the cylinders of an engine. if the balance does not present any serious problems to a particular engine, any number of cylinders of the engine may be clocked against the supply of the mixture during deceleration and coasting.
  • the fuel supply mechanism to a multicylinder engine is so constructed that during deceleration, the intake of the supply gas mixture is interrupted to some of the engine cylinders, so that the amount of the supply gas mixture delivered to each of the remaining cylinders is increased as compared with the corresponding amount for the case of delivering the mixture to all the cylinders.
  • the compression pressure is increased accordingly, for instance when the mixture supply to two cylinders of a four-cylinder engine is interrupted, the compression pressure in the remaining cylinders is roughly doubled.
  • the compression pressure exceeds the combustion limit pressure, and accordingly, perfect explosion takes place in the cylinders which is receiving the supply gas mixture. Therefore, the amount of raw hydrocarbons exhausted without burning can be greatly reduced, as compared with the corresponding amount of known engines.
  • a device for saving fuel and cleansing the exhaust gas in a multicylinder automobile engine having at least one intake manifold and a carburetor means communicating therewith, and a plurality of branch passages communicating said intake manifold with the engine cylinder inlets
  • said apparatus comprising, a plurality of butterfly valves mounted in selected branch passages for isolating the engine cylinders connected thereto from said intake manifold, a first spring means biasing said butterfly valves to an open position, a first piston and cylinder assembly for closing said butterfly valves, connecting means connecting said butterfly valves with said first piston, a conduit means having one end thereof communicating with said intake manifold between said carburetor means and said butterfly valves and the other end thereof in communication with said first piston and cylinder assembly on that side of said first piston opposite said connecting means to communicate negative pressure from said intake manifold to said first piston to close said butterfly valve, the second piston and cylinder assembly connected in said conduit means, said second cylinder having a port therein communicating with the ambient atmosphere, said second piston having a first position for
