Description of the Invention: The present invention relates to an intake vortex control system and method, and more particularly to an intake vortex control system and method suitable for an engine and capable of correctly controlling the arrival of a valve plate. [Prior Art] In the engine design of a general motor vehicle such as a locomotive, in order to improve the combustion process of the engine to improve the combustion efficiency, in addition to focusing on uniformly mixing the engine intake air with the fuel injected from the injector, the other side also tries to make The engine intake produces a rotating, rolling motion that allows the engine to further reduce fuel consumption and achieve lean combustion with low pollution. It is known that the design of the intake port of the internal combustion engine is mostly fixed in geometry, resulting in a fixed air flow and fluid motion pattern, and the performance of the internal combustion engine is therefore limited. A number of improved designs have been proposed. For example, the Republic of China Patent Publication No. 126103 3 discloses an intake port structure in which a valve plate with a hole is formed in one of the inlet ports of the steam head. Thereby, in the engine at low load, the local high concentration of oil and gas can form part of the liquid-gas separation through the hole-operated valve plate and thereby enter the combustion chamber to form laminar flow and induce laminar combustion to further enhance the lean combustion. The effect is achieved together with low fuel consumption and low pollution. In addition, 'Republic of China Patent Publication No. 200925397 also discloses an intake port structure'. The end section of the intake port of the cylinder head is also formed in the same way - the main intake pipe and the primary intake pipe' are the choke valves in the intake port. When the film is turned to the closed position 201209273, in addition to the area corresponding to the cross section of the secondary intake dam, a pressure equalization gap is also generated to connect the intake port with the two intake pipes, so that when the engine is at a medium to low load, In addition to the fact that most of the mixed oil and gas enters the main intake pipe and enhances the vortex effect of the oil and gas in the combustion chamber, and promotes the existence of the lean combustion 'pressure equalization gap, the entire pipeline pressure is also balanced. Regardless of which of the above-mentioned conventional designs, there is a defect that it is impossible to know whether the valve piece is actuated to be positioned (opened or closed). It is conceivable that the right valve plate is not properly actuated to the position, and the fluid motion envisioned is inevitably impossible, so it is necessary to improve this problem. SUMMARY OF THE INVENTION The intake and thirst control system of the present invention comprises a steam head, a throttle valve device, an intake manifold 'a sensor, a drive motor and a controller. The intake manifold is connected between the cylinder head and the throttle device, and an intake control valve plate is disposed in the intake manifold. The sensor correspondingly generates an opening signal according to the position of the intake control valve piece. The drive motor is driven by being coupled to the intake control valve plate. The control power is connected to the sensor and the driving motor and has a reference signal built therein. The controller receives the opening signal of the sensor. When the opening signal is different from a reference signal, the controller calculates the difference according to the second signal. Control the drive motor to rotate. With the above system design 'Because the system is instant grip on the valve position information, it is also based on this information to immediately correct the valve opening degree, ensuring that the engine intake can perform preset preferred fluid motion under various conditions. Type sorrow can ultimately achieve the purpose of reducing fuel consumption and reducing pollution.

In the case where the above-mentioned sensor can also be a resistive position sensor, the configuration can also be that the magnetic body is fixed at = two: = the valve sensor is fixed to the eccentric rotating block. This also has the function of changing the position of the man's correct dry grip valve. The controller can be integrated into the vehicle electronic control unit. Another aspect of the present invention is an intake thirst control method for repairing an opening of an intake control in an intake manifold, the intake manifold being connected between a cylinder head and a throttle device The intake vortex control method comprises the following steps: (a) ❹m gas controls the opening degree of the inter-slice and corresponds to the opening signal; (B) comparing the opening signal with a reference signal; and (C) when The opening signal is different from the reference signal, and the intake control valve piece is rotated according to the difference between the two signals. [Embodiment] - Refer to Figs. 1 to 4. The figure shows a jet engine of a speed-speed locomotive, which includes a cylinder head 11. The steam red head U includes a combustion chamber (1), a double port 201209273 intake port 112, and an exhaust passage (1), wherein the intake passage (1) and the exhaust passage u3 communicate with the combustion chamber 111, respectively. The 30-end lock of the intake manifold is fixed to the steam red head UJ1, and the other end is connected with the throttle device 21, and the throttle device 21 is connected to the air cleaner 22, and the connection relationship between the components also means Have the fact that they are connected to each other. The intake manifold 30 is provided with an intake control valve plate to open the closed-part intake manifold 30 section 'mainly using the shaft 32 to be placed in the intake manifold 30, and the intake control valve piece 31 is fixed on the shaft 32. Both ends of the rotating shaft 32 pass through the main body of the intake manifold 3G, and the t_ end thereof is driven by the driving motor M and the eccentric rotating block 33 is connected to the other end.

The present embodiment also utilizes the Hall sensor 41 as a measure of the measurement of the debt. The difference is that the Hall sensor 41 is fixed on the eccentric rotating block 42 and the magnetic body 43 is fixed on the outer side of the intake manifold 4G. . With the rotation of the rotating shaft 44, the Hall sensor fairy magnetic body 43 also generates a relative displacement as in the above example, so that the corresponding voltage signal can also be issued to cause the controller to grasp the opening position of the valve piece. This also achieves the effect of correcting the control valve to the positioning. In addition to the Hall sensor of the above example, various types of position sensors can be substituted, such as resistive 'photoelectric, acoustic, capacitive position sensors. Those skilled in the art, after considering this specification, can appropriately set and write the corresponding program of the controller according to the principle of action of various known position sensors. Referring to Fig. 6', a perspective view of the intake manifold of the third embodiment is shown. This embodiment utilizes a resistive position sensor 51 to monitor the opening of the valve. The resistive position sensor 51 is fixed to the outer side of the intake manifold 50 and is connected to the exposed portion of the shaft 52. When the rotating shaft 52 is rotated to different positions, the sensor 51 will correspondingly generate different voltage signals due to changes in its internal resistance. Similarly, if the controller 201209273 compares the detected opening signal with the reference signal corresponding to the current vehicle condition according to the built-in correspondence table, the controller controls the rotation of the driving motor according to the difference of the two signals to correct it to the correct one. Opening position. Of course, considering the wear problem, the system design using non-contact sensing means such as Hall sensor is better than using contact sensing means such as resistive position sensor. Referring to Fig. 7, a flow chart of the intake vortex control method, the intake vortex control method of the present invention can be used to correctly control the opening degree of one of the intake control valve plates in an intake manifold. The control method includes: step A, detecting an opening degree of the intake control valve and correspondingly generating an opening signal; step B, comparing the opening signal with a reference signal; and step C, when the opening signal is different from the reference signal , rotate the intake control valve according to the difference between the two signals. The above-described embodiments are merely examples for the convenience of the description, and the scope of the claims is intended to be limited to the above-mentioned embodiments.
