专利摘要:
Valve device includes a valve chamber containing three spherical members of different hardnesses in stacked relation therein, which produce a limited pulsating air flow that is metered in precise amounts at any given time into the fuel/air path of a gasoline powered internal combustion engine to maintain a narrow band air/fuel ratio over substantially all operating modes. The valve chamber has relatively narrow entry and exit orifices in order to increase the velocity of the pulsations generated therein while at the same time reducing the amount of supplemental air flow through the device. The valve seat also has a conical shape to establish line contact with one of the spherical members to assist in obtaining maximum resonation during operation and provide a more positive seal when the engine is not running. The pulsating air from the valve device is preferably introduced into the carburetor beneath the throttle plate in close proximity below the gas idle jets, providing pressure waves therein that produce turbulence substantially throughout the manifold to assist in remixing and atomizing of the fuel and air, whereby substantially equal air/fuel ratio is supplied to every cylinder for better fuel combustion, with consequent increased power, reduced exhaust pollution, and improved fuel economy.

On the housing there is an actuator fan located in front of the inlet for increasing the pressure. Fig. 1 schematically shows a g perspective view of a valve and a power supply system for an internal combustion engine; in fig. 2 - valve of the power supply system with the engine off, cutting; in fig. 3 - part of the valve according to FIG. 2 with the engine running; in fig. 4 - part of the valve of FIG. 2, when the engine is running, during re braking; in fig. 5 is a portion of the carburetor / feed system; sectional view: FIG. B, section A-A, FIG. five; FIG. 7 variants of the implementation of the power supply system with the proposed valve; Fig. 8 is an embodiment of a power supply valve. The supply system valve for the internal combustion engine 1 comprises a housing made of two parts 2 and 3 made of. plastics and forming an internal cylindrical chamber 4 with inlet and outlet. holes 5.and b, and three spherical elements 7-9 placed in chamber 4, arranged in the form of a set between holes 5 and. b of chamber 4 with a gap relative to the walls of the latter; the extreme spherical element 7 is made of polyurethane elastomeric material having a hardness of 89 units on the Shor scale, the other extreme spherical element 9 is made of polyurethane polymeric material having a hardness of 88.5 units on the scale The intermediate spherical element 8 is made of an elastomeric material having a hardness exceeding the hardness of the extreme elements 7 and 9, for example, nylon or teflon, Part 2 of the body is T-shaped and has The bottom tubular nozzles 10 and 11, Part 2 are provided with a thread 12, with which they are connected to part 3 of the housing, and the joint between parts 2 and 3 is sealed by a ring 13. Between the cylindrical wall of the chamber 4 and the inlet 5 there is a conical section 14 forming a saddle surface for contacting with a spherical element 7. The housing part 3 is provided with an inlet neck 15, in which a filter 16 is installed, the mouth 15 has a flange 17, on which longitudinal grooves 18 are made, and part 2 has flexible stop projections 19 having teeth 20, entrance u in the grooves 18 and cooling fins 21, located outside. In the cylindrical chamber 4, at the outlet b, a truncated-conical serrated gasket 22 is installed, which preloads the spherical elements 7-9 when the length of chamber 4 is changed by rotating parts 2 and 3 relative to each other and displacing along the thread. The gasket 22 has a central hole and teeth along the periphery. The rotation of part 3 is carried out by applying force to the flange 17 with the bent protrusions 19, one of which is equipped with a movement limiter 23, so that when adjusting the casing, parts 2 and 3 of the latter are always connected, the channel 24 is connected to the tubular nozzles 10 and 11. outlet b, In the pipe 11 is made vortex chamber 25, communicated with the channel 24 and closed by a stopper 26 installed on the outer end of the pipe 11. The other pipe 10 is connected to the pipe 27 connected to the carburetor 28 installed on the engine 1, Khodnev opening 5 of the cylindrical chamber 4 is made 0.3175 cm diameter and an outlet diameter of 0.518, the valve works as follows. When the engine is not working, the spherical element 7 is pressed to the conical section 14 by the action of the gasket 22 and the spherical elements 8 and 9 and provides for the overlap of the chamber 4, as shown in FIG. 2. Therefore, when the engine is started, the carburetor 28 provides for the preparation of a fuel-air stifling mixture, which is enriched, since air is not supplied through the valve at this time. This achieves a reliable engine start. 1. As soon as the engine is started, a vacuum is formed in the intake path, which is passed through line 27 to chamber 4, under the action of pressure differential. Between the inlet and outlet ports 5 and 6, the spherical elements 7, 8 and 9 are shifted down, the spherical element 7 departs from the cone section 14 and opens a passage for air through the valve, as shown in FIG. 2, the air entering through the valve depletes the fuel-air mixture entering the engine. Moreover, in the vortex start-up process, chamber 25 slows down the opening of the valve for air passage. As soon as air begins to flow through the valve, spherical elements 7–9 begin to vibrate at a JB resonance with an oscillation frequency of about 520, oscillations per second at low airflow rates the course and braking and to 1500 kole-, baniye per second at high speeds of a stream. This provides essentially the same air supply in all modes of engine operation, with the exception of strong braking. The oscillations of the spherical elements 7–9 cause shock waves in the air flow through the valves. The pulsating of its air from the carburetor torus 28 and into the intake tract increases the turbulence of the fuel-air mixture, and ensures its homogenization:; therefore, fuel combustion in the engine is improved. At the same time, with the pulsation, air turbulence is achieved with the help of proklkadki 22 and the vortex chamber 25. The connection of the outlet 6 with the channel 24 at a right angle promotes the spherical elements to resonate in a wide range of operation. The main resonating effect is achieved on the spherical element 7, which it is more responsive to low vacuum in the engine, and provides increased resonance in all modes of operation. This is achieved by the specified hardness, which also contributes to a tighter overlap with the engine not running. The lower hardness of the spherical element 9 provides, at high vacuum values, an increase in its deformation in the lateral direction to a greater extent than the other two spherical elements, as shown in FIG. 4. This limits the supply of additional air during the braking or deceleration mode. When the vacuum is reduced, the deformation of the spherical element 9 towards its original shape through the middle spherical element 8 causes the spherical element 7 to move and reduce the air flow area. The middle spherical element 8, which is harder than the two extreme elements, acts as a piston between NiMi, which provides MP response between the two elements and contributes to the high frequency of the pulsations. The inlet and outlet 5 and 6 increase the speed of the pulsations so that the compression wave generated by the spherical elements 7-9 does not attenuate when the air leaves the valve in the pipeline 2. The speed of the air pulsations increases with decreasing length of the pipe 27. As can be seen from FIG. , 5, and 6, the fitting 29 of the pipe 27 is connected to the Carburetor 28 in the area of the output windows 30 of the idling system under the throttle valve 31. This achieves the effect of pulsation of the air supplied through the valve not only in the carburetor 28, but also e around Zadra selnom space inlet path and into the working volume of the engine cylinders. Although the nozzles of the main and other carburetor metering drums, besides the idling system, are located above the throttle valve 31, however, the fuel flowing out of them gets into the zone of pulsation, which results in mixing of this fuel with the air flowing into the engine. At the same time, the air supply from the valve to the throttle space helps to eliminate any underpressure zones that occur when the throttle valve 31 is not fully open. The valve is adjusted so that the air-fuel mixture supplied to the engine has an air-fuel ratio of 14.6: 1 with a deviation of not more than 0.1% in all modes of operation. Moreover, the valve is regulated at a predetermined flow rate depending on the type of engine size. Fig. 7 shows a variant of the valve installation, when the pipeline 27 has minimum dimensions, and the neck is provided with an air intake manifold 32, which provides a supply of cooler air compared to the air surrounding the carburetor. This valve prevents the reduction of air flow pulsations from the valve to the intake tract, while at the same time also providing increased sensitivity to changes in barometric pressure and ambient temperature. FIG. 8 shows a second embodiment of the valve, in which a cone-cylinder-cylinder nozzle 33 and a fan located in the latter are adjacent to the neck 15. Since the latter is located in front of the inlet 5 and, in its operation, it increases the pressure, valve to a vacuum in the throttle space, which leads to an increase in engine power and increase efficiency. In particular, this valve design improves engine performance in driving, uphill and alpine conditions. Thus, the invention provides for the creation of pulsations in the air flow supplied to the engine intake duct and maintains the air supply in a range that ensures a constant composition of the mixture, which leads to improved mixing of fuel and air and, consequently, to improved fuel combustion.
