Description

The utility model relates to a signal generator device for an internal combustion engine.

Usually in the internal combustion engine, the signal generator using the Hall effect sensing element as the signal element (as shown in Figure 7), in order to tighten the space, the signal element fixing seat A1 is locked on the inner edge of the center hole. On the bearing seat A3 of the rotating shaft A2, as long as more than three ribs are added to the bearing seat A3, the signal element fixing seat A1 can be fixed on the small bearing seat bearing surface. Although this fixing method has only a small space advantages, but there are still some disadvantages: one, because the signal element fixing seat is locked on the bearing seat by the circumference of the inner edge of the center hole, its fixing area and torque are not large, and the diameter of the signal element fixing seat cannot be enlarged. Expansion is prone to adverse phenomena such as vibration. Second, because the signal element fixing seat cannot increase the outer diameter, the position of the signal element has a very small radius from the center of the rotating shaft, which reduces the resolution and accuracy of the timing signal generated by the wing-shaped blade rotor cutting signal element. Third, because the bearing seat is at the bottom of the distribution board, the signal line of the signal element will be guided to the signal output socket on the body seat, which is very troublesome and expensive to assemble. The fourth is to use the commonly used design, the bearing seat is under the signal element fixing seat, there is no space to add signal elements, so it is not suitable for more advanced engine control systems (that is, there must be two signal generators for timing signals. Fifth The commonly used design does not use noise isolation board components, and its timing signal is not suitable for microcomputer control systems.

Therefore, it can be seen from the above that the structure and assembly of the traditional internal combustion engine signal generator obviously still have some inconveniences and defects in actual use and operation, and need to be improved.

Therefore, the creator feels that the above-mentioned defects can be improved, so he devotes himself to research and cooperates with the application of academic theories, and finally proposes a utility model with reasonable design and effective improvement of the above-mentioned defects.

In order to solve the above-mentioned shortcomings of signal generators that commonly use Hall effect sensing elements, the most economical and effective method is to increase the fixing position of the signal element fixing seat, and use the processing steps on the inner wall of the main body seat as the fixing surface. The isolation plate above it is made of materials with good electrical conductivity. When it is inside the distribution board, it can not only block the ozone and water vapor generated by the fire distribution head with the commonly used isolation cover, but also isolate high-voltage electrical noise, so that the signal generator The signal is purer to facilitate the use of the microcomputer controller. In addition, there is enough space available above and below the sensing element fixing seat, two sensing elements can be installed to generate two timing signal waves, so that the user can use a combination of cheap Hall effect sensing elements Signal generator for advanced internal combustion engine control systems.

The purpose of this utility model is to increase the stability of the signal element fixing seat, and increase the use area and space, so the fixing method of the signal element fixing seat is fixedly locked on the bearing seat by the inner edge of the center hole of the signal element fixing seat Instead, the outer edge of the signal component fixing seat is fixed and locked on the inner wall of the signal generator body seat. Since the radius and perimeter of the outer edge of the signal element fixing seat are much larger than the radius and perimeter of the inner edge, as long as a very short diameter is held on the outer edge, a large total fixing area can be obtained, and the position locked by the original screw It is also moved from the inner edge to the outer edge, and the torque for fixing the entire signal element fixing seat is greatly increased, the fixing effect is better, and the signal element is less susceptible to the vibration of the engine. And because the signal element can be placed at a larger radius from the center of the rotating shaft, the total circumference cut by the wing-shaped blade rotor will be greatly increased, while the total angle of 360° remains unchanged, so that when the wing-shaped blade rotor cuts the same circumference, it can represent more The narrow angle value can greatly improve the accuracy and resolution of the waveform of the timing signal. And when the signal generator of the present invention is applied to the microcomputer system, its timing signal is not disturbed by external high-voltage electrical noise, especially when there is a distribution board, electrical noise will be generated when the sub-fire breaks out. It will be separated by the isolation board (the isolation board must be made of good conductive material). In an advanced engine control system, there must be two timing signal waves. Due to the space under the signal element fixing seat, the utility model can add another set of signal elements and wing-shaped blade rotors, so cheap elements can be used. Form a signal generator suitable for use in modern engine control systems. And because the position of the signal component fixing seat is improved, one or two signal components and signal output sockets can be pre-wired during assembly, and assembled into one component, and then assembled on the signal generator or the distribution board, so that The assembly is relatively easy, and the assembly cost is greatly reduced.

The signal generator device used on the internal combustion engine of the utility model is composed of a body seat, a rotating shaft freely rotating on the body seat, and more than one piece is fixed on the rotating shaft to have a wing shape of a fan wing parallel to the axis at right angles. The vane rotor, a signal element fixing seat locked on the body seat, more than one signal element, a signal output socket fixed on the body seat, a noise isolation plate that can isolate electrical noise and cover the opening of the body seat and other components constitute. One end of the rotating shaft meshes with the camshaft or crankshaft system of the engine, which can rotate synchronously with the engine, and then drive the wing-shaped blade rotor to rotate synchronously with the engine. When the wing-shaped blade rotor rotates, the signal element is cut, and the commonly used Hall effect is applied. The sensing element is a signal element. When the Hall effect sensing element is cut by the blade rotor with good magnetic permeability, it will generate a square wave signal in the signal output socket and output it to the microcomputer controller in the engine control system for Control the fuel injection and ignition of the engine. When the ignition system of the engine uses a distribution board, the signal generator of the present utility model is integrated with the distribution board and installed under the distribution board. If there is no distribution board, the signal generator of the present invention is an independent component . The main feature of this utility model is that the signal element fixing seat is fixed on the main body seat with the outer edge of its entire circle as the fulcrum, instead of being fixed on the bearing seat of the rotating shaft with its inner edge as the fulcrum as in the usual design. The new type not only makes the entire signal component fixing base more stable and less prone to vibration, but also increases the use space of the fixing base. Not only the upper and lower sides of the fixing base can be used to fix the signal components, so as to meet the new engine control system that requires more timing signals. Requirements, and the signal element can be fixed at a position farther from the rotating shaft, so that the signal accuracy and resolution generated by the blade rotor cutting are higher.

Another feature of the utility model is that holes are provided on the asymmetric wing-shaped blade rotor relative to the positions of the right-angled blades to reduce the weight of the blade and achieve better dynamic balance, so that when the wing-shaped blade rotor rotates The resulting vibration is reduced.

Another feature of this utility model is that a noise isolation board is provided above the signal generator. The isolation board has conductivity, and on the one hand, it can isolate the flashover of the sub-ignition head, the ignition of the ignition coil and the spark plug, and other possible high voltages. Electrical noise, on the other hand, can isolate a large amount of ozone generated by the flashover of the distributor. The ozone is unstable, and it is easy to generate moisture inside the distributor, and make the wing blade rotor made of iron material rust. When there is too much rust , and it is easy to short-circuit the signal components, causing timing signal errors and confusion, resulting in disordered engine operation. When the signal generator is not used as a power distribution board, the utility model is used as a top cover to prevent dust, moisture and foreign objects from falling into the signal generator.

Another feature of the utility model is that sensing elements can be installed on the upper and lower sides of the signal element fixing seat, so that when the number of timing signals increases, the phenomenon of overcrowding of sensing elements and wing-shaped blade rotors will not be caused. .

As shown in Fig. 1, when the engine ignition system needs to use the distributor (DISTRIBUTOR), the embodiment of the signal generator 1 device of the present invention is installed inside the distributor 2.

The signal generator 1 of the utility model is composed of a body seat (HOUSING) 3, a shaft (SHAFT) 4 that can rotate freely in the body seat 3, and more than one piece (including one piece) fixed on the shaft 3 with a right angle to the axis Wing blade rotor (VANE TYPE ROTOR) of parallel fan wings 5, a signal element fixing seat (SIGNAL ELEMENT MOUNTING PLATE) fixedly locked on the body seat 3, 7, more than one (including one) signal element (SINGNAL ELEMENT ) 8. A signal output socket (PLUG) 9 fixed on the body seat 3, and a noise isolation plate (NOISE ISOLATING PLATE) 10 that can isolate electrical noise (NOISE) and cover the opening of the body seat 3, etc., One end of the rotating shaft 4 meshes with the camshaft or crankshaft system of the engine, and can rotate synchronously with the engine, thereby driving the wing-shaped blade rotor 6 to rotate synchronously with the engine. When the wing-shaped blade rotor 6 rotates, it will cut the signal element 8 . In general applications, the commonly used Hall effect sensing element (HALL EFFECT SENSOR) is used as the signal element 8. When the Hall effect sensing element is cut by the blade rotor 6 with good magnetic conductivity (MAGNETIC CONDUCTIVE), it will generate a square wave. The signal (SQUARE WAVE SINGNAL) is output to the microcomputer controller (MICROCOMPUTER CONTROL UNIT) in the engine control system (ENGINE MANAGENET SYSTEM) through the signal output socket 9 to control the fuel injection (FUEL INJECTION) and ignition (IGNITION) of the engine . Distributor 2 of the present utility model is arranged above signal generator 1, and its top is a distributor cover 11, and there is distributor 12 in it, and distributor 12 is pinned on the upper end of rotating shaft 4, and the lower part of distributor 12 is arranged. The noise isolation board 10 is made of conductive material, so it can not only isolate the ozone and the water vapor produced when the distributor 12 flashes over, but also the arc sparks generated by the high voltage jumping over the ignition point will make the air in the air Oxygen turns into ozone. Ozone easily combines with iron metal surface to form oxidized iron scale, and combines with a small amount of hydrogen in the air to form water vapor. This water vapor accumulates into water droplets over time, which accelerates the rusting of iron metal surface and is isolated by this noise. After the plate 10 blocks, most of the ozone in the distribution board 2 will circulate through the air hole 13 on the distribution board cover 11 and the atmosphere. In addition, high-voltage electric wave noise will be generated when the ignition head 12 jumps over. If the noise is not isolated, it will induce the conductive wire of the signal generator 1, causing the signal generator 1 to output abnormal noise waveforms, which may easily cause engine control system and microcomputer control. In order to provide the correct timing signal wave for the microcomputer controller, the signal generator 1 of the utility model is specially made of good conductive material such as metal or electroplated plastic, so that the high-voltage electric wave cannot penetrate the noise isolation board 10. The lower end of the rotating shaft 4 is meshed with the crankshaft or camshaft of the engine, so it can rotate completely synchronously with the speed of the engine. The first wing-shaped blade rotor 6 is fixed on the rotating shaft 4 and rotates completely synchronously with the rotating shaft 4. In this embodiment, the wing-shaped blade rotor 6 is positioned and locked on the rotating shaft 4 by the screws 14 , but in application, various methods can be used to position and lock the wing-shaped blade rotor 6 on the rotating shaft 4 . When the wing blade rotor 6 and the rotating shaft 4 rotate synchronously with the engine, the fan blade 5 will rotate on a fixed circle and cut the signal element 8. In this embodiment, the commonly used Hall effect sensing element is used as the signal element 8. The application cost of this kind of sensing element is very low. Its advantage is that the signal element 8 of the Hall effect sensing element is placed on the signal element fixing seat 7 and positioned by riveting, screw locking or any other method. On the positioning hole 15 of the signal element fixing seat 7, it is firmly combined with the signal element fixing seat 7, the output signal line 16 of the signal element 8 passes through the small hole 17, and is connected with the signal output plug 9, thereby connecting signal output. If the signal line 16 is very long, it must be fastened with the hook-shaped groove 18 on the surface of the signal component holder 7, so as to avoid the signal line from being scattered and floating or being touched by the wing-shaped blade rotor 6. In addition, the second wing-shaped blade rotor 20 with fan wings 19 is also positioned and locked on the rotating shaft 4, but below the signal element fixed junction 7, and its device direction is the same as the direction of the first blade-shaped blade rotor 6. On the contrary, make its fan wing 5 and fan wing 19 opposite, and all towards the signal element fixing seat 7, the fan wing 19 of the second wing-shaped blade rotor 20 will cut the second signal element 21 (used in this embodiment) Hall effect sensing element), the second signal element 21 which is a Hall effect sensing element is set under the signal element fixing seat 7, and fixed under the signal element fixing seat 7 by riveting or screws , its output signal line 22 is also fastened and positioned by the small hole 23 through the hook groove 18, and is connected with the signal output socket 9, thereby outputting the second timing signal wave.

The signal element fixing seat 7 is positioned and locked on the flange-shaped positioning surface 25 on the body seat 3 with its outer edge as the fixing surface 24. This positioning surface 25 has its precision through processing, so that the signal element fixing seat 7 can be stabilized. set on the body seat 3, and lock the position with the screw 26, when the screw 26 is loosened, the position of the signal element fixing seat 7 can be fine-tuned to change the relative position of the timing signal wave and the engine angle, the signal element is fixed The seat 7, the signal elements 8, 21 and the signal output socket 9 can be pre-assembled into an assembly, which makes the assembly of the entire signal generator 7 easy. And the body seat 3 above the signal output socket 9 has an empty slot 27, which can be used to lock or loosen the fixing screws 14, 28 of the wing blade rotors 6, 20, and to assemble and position the signal output socket 9. This empty groove 27 is sealed with rubber 29 when assembling, to prevent foreign matter from entering in the signal generator 1, and signal output socket 9 is pushed down so that it does not loosen simultaneously.

The signal generator 1 mentioned in the previous item is equipped with two signal elements (Hall effect sensors) 8, 21, so it can generate two timing signal waves, and its waveform follows the movement of the airfoil rotor 6, 20. The general advanced engine control system must have two timing signal waves. The number of waveforms of a timing signal wave is the same as the number of cylinders of the engine. The waveforms are used to accurately calculate the angular velocity of the engine, as shown in Figure 4-1 and 4 -2 shows the wing-shaped blade rotor 6 used by the four-cylinder engine. The position for cutting the signal element is the fan wing 5 parallel to the center hole of the wing-shaped blade rotor 6. The wing-shaped blade rotor used by the four-cylinder engine needs four Sheet fan wing 5. If the airfoil rotor 31 used by the six-cylinder engine (as shown in Figures 4-3 and 4-4), then six fan wings 30 are required, and all fan wings 5, 30 are respectively on the same circumference and the circumferences are equal. Divided into a certain angle, and so on to eight-cylinder engines or other numbers of engines. The other timing signal wave has only one waveform, which has nothing to do with the number of cylinders of the engine. Its waveform is used to determine the specific reference position of the engine. For systems with point-type fuel sequential injection (MULTI-POINT-FUEL-INJECTOR SEQUENTIAL INJECTION), the second timing signal must be used for the control system to calculate the fuel injection time, as shown in Figure 4-5 and 4-6 Shown, this airfoil blade rotor 20 has only a fan blade 19. Because there is only one fan wing 19, the wing-shaped blade rotor 20 is asymmetrical, and centrifugal vibration is generated when it rotates. Therefore, part of the material on the table top 32 must be dug out. If a hole 33 is provided, the rotational moment can be balanced. The shape and working principle of the single-piece fan wing 19 are similar to those of the multi-piece fan wings 5 and 30 mentioned above, both of which cut respective signal elements (Hall effect sensors) to generate signal waves.

In a simpler engine control system, its signal generator 1 only needs an engine timing signal, and now the airfoil rotor 6 in the device of the present utility model only needs one (the airfoil blade of another single fan wing The rotor is omitted), and the relative signal element (Hall effect sensor) 8 only needs one (as shown in Figure 2), in order to generate only one engine timing signal generator 1, the characteristics and work of the combination of its components The principle is exactly the same as the signal generator 1 that produces two engine timing signals shown in Figure 1, except that the signal generator 1 of one engine timing signal combines the wing-shaped blade rotor 20 of the single-piece fan wing 19 and a signal element 21 cancels, and retains the airfoil blade rotor 6 of many fan wings 5.

At present, the more advanced engine ignition system (ENGINE IGNITION SYSTEM) no longer uses the distributor (DISTRIBUTOR), but uses a microcomputer to control multiple ignition coils (IGNTIONCOIL), forming the so-called DISTRIBUTOR LESS IGNITION SYSTEM ), the signal generator 1 (as shown in Figure 3) at this time does not need to have the components and designs of the distributor cover 11, the distributor 12 and the air hole 13 in the aforementioned Figures 1 and 2, so its rotating shaft 4 The length is shortened, and the noise isolation plate 10 also has the function of a cover plate. In addition to preventing external electrical noise such as ignition coils, spark plug flashovers, and high-voltage wires, it also prevents the intrusion of various foreign objects. Therefore, the noise isolation plate 10 is still It must be made of conductive material, and all the other elements have the same structural features and functions as shown in the embodiment of Fig. 1. In addition, with the different lengths of the body seat 3, rubber 29 parts can be used or cancelled. Of course, in order to prevent external electrical noise from inducing the signal element 8 and the output signal line 16, the main body seat 3 shown in Fig. 1, Fig. 2 and Fig. 3 must also be made of a conductive material or a material whose outer surface is plated with a conductive substance. In this way, electrical noise will not invade the inside of the signal generator 1, and in a high-quality control system; the outer surface of the signal output socket 9 is to prevent noise intrusion, such as with an electroplating layer or with a metal mesh or with a layer of conductive material. .

Figure 5 and Figure 6 show the relationship between the timing signal wave and the ignition and fuel injection timing required by the four-cylinder four-stroke engine control system, and Figure 5 shows the ignition and fuel injection when there is only one timing signal wave Timing relationship, usually this kind of engine control system cannot operate too precise fuel injection time, it can only be applied to relatively rough injection (GROUP INJECTION), synchronous injection (SIMULTANEOUS INJECTION) and single point injection (SINGLE POINT FUEL INTECTOR SYSTEM). Figure 5 (a) shows the engine angle coordinates of the four-cylinder engine with the top dead center of the first cylinder as the origin; Figure (b) shows the first timing signal wave, which is used to allow the microcomputer to control and calculate the speed of each section of the engine , and used to control the engine ignition timing and fuel injection timing and time width; Figure (c) is the ignition timing position map of each cylinder; Figures (d) and (d') are the multi-point fuel injection system ( Batch injection method (GROUP INJECTION) in MULTI-POINT-FUEL-INJECTOR-SYSTEM); Figure (e) is another fuel injection method, which is also a multi-point fuel injection system but is a synchronous injection method (SIMULTANEOUS INJECTION), The nozzles of the four cylinders inject fuel at the same time, and the ignition timing is not different; Figure (f) is a single-point fuel injection system (SINGLE-POINT-FUEL-INJECTOR-SYSTEM), generally throttle body injection (THROTTLE- BODY-INJECTION) fuel injection timing is wide and timely, and its ignition timing is also as shown in Figure (c). Figure 6 shows the relationship between ignition and fuel injection timing when there are two timing signal waves. Figure 6 (a) is also the engine angle coordinates; Figure (b) is the second timing signal wave to show the engine It is at the specific position of the first cylinder as the reference point, coupled with the data of the calculation of the rotational speed generated by the first timing signal wave in Figure (c), so that the microcomputer controller can control each nozzle of the multi-cylinder engine separately , so it is possible to perform sequential injection (SEQUENTIAL INJECTION) in a more accurate multi-point fuel injection system, as shown in figure (e). At this time, the ignition timing shown in Figure (d) is the same as the ignition timing applied by the three fuel injection modes shown in Figure 5.

The installation position of the utility model can not only be connected to the camshaft of the engine, but also can be connected to the crankshaft or any mechanism that can be synchronized with the engine timing, and the signal element of the present invention can be not only a Hall effect sensor, but also a It can be a variety of components that can generate electrical (including voltage, current, resistance, inductance, capacitance, electromagnetic, etc.) induction signals. Furthermore, the number of signal elements of the present invention can not only be one or two, but can also be multiple on one side, and the number of wing-shaped blade rotors of the present invention can not only be one or two, but can also be Multiple, and the signal component fixing seat of the present utility model can be not only one layer, but also multiple layers.

To sum up, the utility model has the advantages of stable signal component fixing seat, reduced vibration of wing blade rotor and isolation of high-voltage electric wave noise. , and then filed an application for a new patent according to the law.
