Negative pressure inhalation control method and device for intake system

The present invention relates to a method and apparatus for controlling a negative pressure intake and suction of an intake system, and is provided with at least one one-way shutter coupled to at least one link group having at least one different rotation axis and a suitable restoring force portion. It becomes a one-way valve assembly passively responding to the airflow opening and closing to regulate the suction of the suction system and the suction of the negative pressure source, and is provided for the machine provided with the intake system and the exhaust system. Used in the intake pipe, for example, an internal combustion engine, a vacuum cleaner, an air extractor, a turbine engine, a tool including a turbojet, a turbofan, a turboshaft, and a turboprop.

At present, it is known that an internal combustion engine (such as a steam locomotive engine), a vacuum cleaner, an air extractor, a turbine engine and the like use a negative pressure air intake system and a negative pressure source to generate a negative pressure, and the outside air is sucked into the negative pressure air intake via an intake pipe. The system then uses an exhaust system to vent the air. The negative pressure intake system of the internal combustion engine is, for example, a cylinder of a natural intake internal combustion engine, an intake manifold, an intake pipe, etc., and a turbocharger intake end and an intake pipe of the supercharged internal combustion engine during boost operation, and the like The intake end of the supercharger of the internal combustion engine and the intake pipe. The pump of the above vacuum cleaner and the air extractor is the negative pressure source of the negative pressure intake system. The turbine engine includes a turbojet, a turbofan, a turboshaft, a turboprop, etc., and the pressurized fan blade is a vacuum inlet system and a negative pressure source thereof. .

Taking a turbocharged internal combustion engine as an example, when the turbine is not actuated, the natural intake is based on the principle of negative pressure, that is, when the turbine is actuated, the intake end of the turbine is still under negative pressure, and the output end of the turbine is supplied. The air supply is blown to the cylinder at a positive pressure. When the turbine is actuated, the intake pipe section of the turbine intake end, according to PV=nRT and related or the derivative principle, the negative pressure will rise in the intake pipe section, so the turbine intake end will draw more air, and the turbine output is supplied. The gas pipe section is converted from negative pressure to Send more air for positive pressure; this is the design demand for this type of supercharger. By the same token, an internal combustion engine, a vacuum cleaner, an air extractor, and a turbine engine having both an intake system and an exhaust system are expected to inhale more air by a negative pressure source to draw air with a forced negative pressure.

The method and apparatus for improving the efficiency of an automobile engine have been discussed by the inventors in the previously applied U.S. Patent No. 7,446,694, Chinese Patent ZL200610098538.6, European Patent EP2032823, Taiwan Patent TWI306133, and other multinational patents (hereinafter referred to as "pre-patent"). . When implementing the technical content of the pre-patent, when a one-way valve is installed in the intake pipe of an internal combustion engine that has an EGR system and a fuel injection type internal combustion engine that is not modified with a natural intake vehicle, according to PV=nRT and related or the derivative principle, Increase the negative pressure of the suction of the negative pressure system in the intake pipe and downstream of the installation position. This increase of negative pressure not only increases the intake efficiency, but also makes the combustion more complete. At the same time, it also makes the exhaust gas recirculation of EGR (Exhaust Gas Recircuration) in today's internal combustion engine technology. It turns out that more exhaust pipe exhaust gas is introduced into the intake system and merged into the cylinder combustion, which leads to more complete combustion and at the same time reduces the combustion temperature according to the EGR principle and naturally reduces NOx emissions. In the same way, the patented technology can also improve the system negative pressure of the natural intake of the fuel injection turbocharged internal combustion engine and the turbine operation, which can be measured by the negative pressure gauge test reading. The Ford Kuga 1.6L turbocharged petrol car with the patented product is the basis for increasing the actual intake negative pressure and allowing the instrument to fail to reach the original design speed.

Up to now, in the exhaust emissions generated by automobiles having an internal combustion engine of an EGR system in the world, NOx, HC, and CO are in a relationship of mutual growth and ablation. However, in addition to the technology of the prior patents, there is currently no technology in the automotive industry that can simultaneously reduce or reduce the three exhaust gas contents of NOx, HC and CO in exhaust gas.

The above-mentioned prior patents increase the negative pressure of the negative pressure system of the fuel injection type internal combustion engine, so that when the cylinder is inhaled or pressurized by the natural intake air, the positive pressure enters more air, causing more complete combustion and allowing the engine to output. Better, so the engine output related to horsepower, torque, fuel consumption, air conditioning, generators, uniform performance and overall gain; at the same time, of course, also related to the intake manifold negative pressure (such as brakes, EGR, The performance of carbon canister recycling, etc.) Comprehensive gain improvement; that is, overall engine performance.

Therefore, if the newly manufactured vehicles in the future are included in the method technology of the former patent, It is inevitable that the combustion efficiency of various engines (such as gasoline-diesel engine homogeneous combustion HCCI, in-cylinder direct injection, traditional internal combustion engines, etc.) can be greatly improved, and the engine performance is fully improved. The achievable efficacy is verified by the test results of China Xiangyang National Automobile Quality Supervision and Inspection Center (please refer to Table A before the device report number: 14-WT-JN-01383, Table B device report number: 14-WT-JN -01384), Table A, Table B, is the test value before and after the patent one-way valve product. The data shows that the CO content in the exhaust gas is reduced from 0.81g/km to 0.54g/km, and the HC is reduced from 0.12g/km to 0.08g/km, NOx decreased from 0.05g/km to 0.02g/km; it is confirmed that the device with the prior patent technology can significantly reduce the exhaust emissions of NOx, HC and CO at the same time, and it shows that the industrial application can greatly reduce the existing technology for the internal combustion engine. The cost of post-combustion treatment.

In 2013, Beijing Academy of Environmental Sciences confirmed that the cause of the damage was mainly from NOx and VOCs emitted by automobiles. VOCs in automobile exhaust emissions must be proportional to HC and CO emissions, that is, HC and CO emissions are extremely low when combustion is complete, and VOCs emissions must be extremely low. However, not only China, but the world, cannot quickly and effectively control and improve it. It is indeed impossible to quickly and effectively control and improve the huge 1.4 billion factory cars. And before The test report of China National Automobile Quality Supervision and Inspection Center of Puyang confirms that the former patented mechanical one-way valve can directly improve the downstream suction system of the intake pipe installation position without the need of soft and hard body matching. The negative pressure of the gas, and immediately and effectively reduce the emission of NOx, HC and CO in the exhaust pipe of the automobile.

However, due to the fact that the naturally aspirated car is traveling at an increased speed, the rotational speed The higher the negative pressure in the negative pressure zone, the lower the negative pressure gauge can be obtained by the intake manifold. The one-way shutter closing torque of the above patent is only the minimum when the stationary is not actuated. When the speed of the automobile increases, the one-way valve actually faces the intake air flow volume and the relative negative pressure becomes lower and lower, so the air flow speed and the air flow of each speed in each air intake process are When the larger and larger one-way shutter closing torque is equivalent, the one-way valve balance opening degree is formed; if the torsion spring torque is set to be larger, the closing torque of the one-way valve in the whole intake process is naturally larger, and then the The smaller the effective airflow path formed by the one-way valve balance opening in each air intake process in the air pipe, especially affecting the intake air flow in the medium and high speed range and reducing the combustion efficiency of the engine, resulting in lowering The phenomenon that the medium and high speed range can increase the output amplitude is that it is still worth solving this problem and improving the above-mentioned one-way shutter.

In view of this, in order to improve the above-mentioned shortcomings, the inventors have actually measured that when the automobile engine maintains the medium-high speed range while traveling, if the one-way shutter closing torque is reflected to the negative pressure value read by the meter, the original negative pressure is appropriately maintained. The setting of the higher value allows the actual output of the terminal to be greatly increased after the engine is burned, and the present invention has been developed.

The main object of the present invention is to provide a negative pressure intake and inhalation control method and device for an intake system, which is provided by adjusting a closing torque of a one-way flap by setting a link group on a one-way shutter to make the one-way flap After being turned on, it is actuated corresponding to the connecting rod group, thereby further improving the intake efficiency of the negative pressure intake air of the intake system.

Figure 4 is a cross-sectional view of the embodiment of Figure 1 when the one-way flap is fully open.

Please refer to FIG. 1 and FIG. 2 , which are the first embodiment of the negative pressure intake and suction control device of the intake system of the present invention, which is provided for the machine provided with the negative pressure air intake system and the exhaust system. The intake pipe includes a one-way shutter assembly including a one-way valve 1, two link groups (21, 22), and a different axis from the one-way flap rotation shaft 12. The connecting rod group rotating shaft 23, a restoring force portion 3 and two positioning stoppers 4, wherein the one-way shutter 1 comprises a fixed tube 11 and a one-way flap disposed in the fixed tube 11 in a radial direction The rotating shaft 12 and the two-way flap 13 pivoted on the one-way flap rotating shaft 12 are disposed.

Each of the link sets (21, 22) includes a first link (211, 221) and a second link (212, 222), wherein one end and the second end of the first link 211 of the link set 21 One end of the connecting rod 212 is pivotally connected to a connecting rod rotating shaft 213 and connected to each other, and the other end of the first connecting rod 211 is pivotally connected to The other end of the second link 212 is pivotally connected to one of the one-way flaps 13 so that the link set 21 is pivotally connected to the link set rotating shaft 23 and Between the one-way flaps 13. Similarly, one end of the first link 221 of the other link set 22 and one end of the second link 222 are pivotally connected to a link rotating shaft 223 to be connected to each other, and the other end of the first link 221 is pivoted. Connected to the linkage rotating shaft 23, the other end of the second link 222 is pivotally connected to the other one-way flap 13.

The restoring force portion 3 is a torsion spring (or any other type of spring having the same function) disposed on the rotating shaft 23 of the link set, and the two ends of the restoring force portion 3 are respectively pivotally connected to the connecting body The rod rotating shafts (213, 223) are used to apply one of the one-way flaps 13 through the second connecting rods (212, 222) of the respective link sets (21, 22), thereby forming a one-way live The closing force of the blade 13 against the positioning stop 4 is abutted against the closing torque, and the relatively large closing of the restoring force portion 3 when the opening of the one-way flap 13 is increased by the connecting rod group (21, 22) is reduced. Torque.

The two positioning stops 4 are disposed in the fixed tube 11 to limit the positions of the one-way flaps 13 so that the one-way flaps 13 can abut against the positioning when the stationary ones are in a fully closed state. Stop member 4.

In this embodiment, the one-way flap 13 can be in a fully closed state and a fully open state, and the link sets (21, 22) and the restoring force 3 are configured. The closing torque of the one-way flap 13 in the unactuated fully closed state (as shown in Fig. 3) is greater than the closing torque of the one-way flap 13 in the fully open state (as shown in Fig. 4). In FIG. 3, the one-way flaps 13 are held in a minimum gap and are not in contact with the fixed tube 11 and are stationary against the positioning stop 4, wherein the restoring force portion 3 is rotated relative to the linkage shaft 23 The urging rotation method vector size 100 series stretches the link group 21 first link 211 and the second link 212 to pull the one-way flap 13 , and the projection component of the normal vector 100 exerts a force 101 and force The size 102 is the same. The projection rotation normal vector size 103 of the force application size 102 relative to the one-way flap rotation axis 12 is the rotation normal vector size at which the one-way flap 13 is closed. In FIG. 4, the one-way shutters are in a fully open state, wherein the restoring force portion 3 is biased relative to the link group rotation axis 23 by a rotation normal vector size 200 to stretch the link group 21 first link 211 And the second link 212 pulls the one-way flap 13 , and the projected component of the normal vector 200 in the figure is the same as the force-applying size 202. The projection rotation normal vector size 203 of the force application size 202 relative to the one-way flap rotation axis 12 is the rotation method in which the one-way flap 13 is closed. Vector size.

Industrially adjust the torsion spring material, wire diameter, number of turns, and outer diameter of the disk to obtain the initial torque and maximum rotational torque required by the design; in Figures 3 and 4, when the force is 200 Deliberately arranged the same as the force of 100, the maximum opening force of the one-way flap 13 is 203, which is 15.7% of the static force 103. As can be seen from the figure, the intensity of the restoring force can be changed, that is, It is assumed that the torque when the torsion spring 3 is rotated most is greater than the torque ratio of the initial pre-force number, and the ratio of the actual magnitude of the torsion spring 3 to the magnitude of the applied force 100 is reflected by the actual setting. The adjustable ratio of the force application size 203 to the force application size 103 can be adjusted from 15.7% to more than one point; the maximum opening torque of the one-way valve of the prior patent must be the maximum. It is inevitably different from the case where the torque at rest is 100% or more. In this paragraph, for convenience of explanation and comparison, the torsion spring of the one-way flap 13 is the most arbitrarily arranged as shown in Fig. and the restoring force portion 3 (torsion spring) is the same as the force 100; The size 200 is bound to be greater than the torsion spring force of 100.

In the present embodiment, the link groups (21, 22) and the restoring force portion 3 are configured such that the one-way flaps 13 are stationary and the fully closed state closing torque is greater than the one-way flap 13 fully open state. The closing torque is provided in the intake pipe of the negative pressure intake system of the automobile (for example, between the intake port of the natural intake car intake pipe and the throttle valve) corresponding to the intake pipe The internal intake air flow is actuated, so that the closing torque of the one-way flaps 13 of various open states can be such that the negative pressure value in the downstream intake manifold is lower than that of the intake air in the respective speed ranges. When the control device is used, the negative pressure value is higher, the intake air can be more effectively gained, the combustion efficiency is better, and the actual output of the terminal is greatly increased after the engine is burned. That is to say, urban vehicles frequently take off vehicles and high-speed vehicles, and each control speed domain can respond more quickly, so that the medium and low speeds have higher output torque, and the medium and high speed domains obviously speed up faster. Then, the Ford Kuga 1.6L turbocharged gasoline vehicle installed in the front pipe section of the turbine inlet end of the present embodiment is compared with the 90kph fixed speed of the same load climbing section, and the original turbine output positive pressure is 0.45kg/cm ² . The pre-patented product with the full-speed domain performance and the turbine output positive pressure of 0.5kg/cm ² should be considered for installation. The installation sample should consider the full-speed range performance of the present invention. The set sample and the turbine output positive pressure are 0.57kg/cm. ^2, a ^{0.45kg / cm 2, 0.5kg / cm} 2, 0.57kg / cm 2 clearly show the present invention, i.e., into a ho-based improvement of having superior performance.

In addition, when the 2004 Ford Mondeo 2.0L petrol car was installed, this embodiment was installed. Compared with the patented products installed before the application, in addition to the smoother and faster response of the urban stoppage, the expressway re-acceleration reaction and speed increase are also significantly faster; then the throttle is not compared. At the actual final speed, the product of the pre-application patent has gained 180 kph, and the efficiency produced by the device of this embodiment is preferably increased to 203 kph. Re-disclosed, the Mondeo 2.0L car owner is a city-type car, and each time the oil is flushed to the spare oil for a long period of time, the original factory runs about 400 kilometers. The gain is about 470 kilometers, and the efficiency of the device in this embodiment is increased to about 520 kilometers. Accordingly, the present invention, together with the prior patents, is a software that has not actually changed the vehicle, and it has become apparent that it is possible to significantly surpass the prior art to achieve an immediate and substantial reduction in NOx, HC, and CO in exhaust emissions. The present invention firstly discloses such a technical means, and any one of ordinary skill in the art to which the present invention pertains, the change of the one-way shutter closing torque regenerated according to the description of the present invention should belong to the present invention as long as it is greater than the last condition. The scope of the disclosed technology.

In another embodiment, the link set and the restoring force portion (eg, a spring) are The fully closed state closing torque configured to cause the one-way flap to be stationary is less than the closing torque when the one-way flap is fully open. This technology is suitable for medium and high speed domains such as generators, such as extended-range electric vehicles. The demand is mostly for the output of medium and high-speed power generation; not only can the same output be achieved at significantly lower than the original speed, especially energy saving and exhaust emissions. It has a very superior performance. Furthermore, in comparison with the actual product, the initial pre-force is set by comparing the present embodiment of the same specification one-way flap with the same specification torque spring device and the same specification one-way flap of the same specification torque spring device. The closing torques of the fully closed state one-way flaps that are the same, that is, the two are not the same, are the same or the same, because the angles of the one-way flaps are close or the same, but under the action of the linkage group, the embodiment is simple. The closing torque when the flap is fully opened can be significantly smaller than the closing torque of the one-way flap of the prior patent, which is obviously superior. The present invention firstly discloses such a technical means. Anyone who has a general knowledge in the technical field to which the present invention pertains, the change of the one-way shutter closing torque which is regenerated according to the description of the present invention should belong to the present invention as long as it is less than the last condition. The technical scope disclosed by the invention.

In still another embodiment, the link set and the restoring force portion (eg, a spring) are The fully closed state closing torque configured to cause the one-way flap to be stationary is almost the same as the closing torque when the one-way flap is fully open. This kind of technical setting is especially suitable for the general national car whose main appeal is energy saving. That is, the urban area frequently stops at low and medium speeds and can have higher output torque. Of course, because of the main demand for energy conservation, it is necessary to compromise and reduce the high-efficiency output of some medium and high speed domains. The present invention firstly discloses such a technical means, and any one of ordinary skill in the art to which the present invention pertains, the change of the one-way shutter closing torque which is regenerated according to the description of the present invention should belong to the present invention as long as it is equivalent. The scope of the disclosed technology.

Therefore, the present invention not only sets the same one-way valve to the intake system. In the negative pressure intake pipe, the one-way valve assembly is constructed by connecting at least one set of connecting rods to achieve an improved effect, and the utility is superior to the one-way valve in the prior patent. In addition, the present invention can further grasp that, in various applications, as described above, the one-way shutter closing torque can be set separately to be larger, smaller or equivalent when the angle is the most open, and the more precise link group can be applied. The starting change ratio of the one-way shutter opening and closing torque is appropriately adjusted with the restoring force portion, and the change of the one-way shutter opening and closing torque can be made differently, which is the one-way one-way shutter of the disclosed one-way shutter at the most open angle. It is impossible to achieve a situation where the shutter closing torque is always maximum. Furthermore, the invention is also applicable to negative pressure intake manifolds of other types of intake systems, such as the vacuum cleaners, air extractors or turbine engines described above.

Moreover, the aircraft is most afraid of foreign objects such as bird attacks invading the turbine engine, even though the aircraft The manufacturing company has improved the impact strength of the machine parts, but so far, there is no fence pilot isolation. Undoubtedly, the intake pipe fence affects the intake air. If the device or method of the present invention is applied, the benefit of a small portion of the gain of the air is sacrificed, and the foreign matter can be forced out of the fence by matching the foreign matter with a proper angle outside the intake nozzle, thereby achieving the effect of the overall intake gain, thereby forcibly isolating Eliminate and greatly reduce the serious damage that can not be compensated by the invasion of foreign objects such as bird attacks, and greatly improve the flight safety of aircraft.

In summary, the present invention can achieve the intended purpose of the invention and provide a The negative pressure inhalation control method and device of the gas system is of great value in industrial use, and the invention patent application is filed according to law.
