Abstract
The utility model relates to an automobile engine EGR valve including a valve body, a motor arranged in the valve body, and a valve core, the valve core is linked and cooperated with the motor. The automobile engine EGR valve further includes a microprocessing control unit and a sensor for detecting the opening degree position of the valve, the microprocessing control unit is electrically connected to the sensor and the motor, and the microprocessing control unit includes a host communication processing module, an input acquisition module for acquiring the input data of the sensor, a valve opening degree control and calculation module, and a motor driving module for driving the valve. By adopting the above technical scheme, the automobile engine EGR valve provided can accurately control the opening degree of the valve to further ensure the accurate control of the exhaust gas values.
Description
Technical field
The utility model relates to a kind of exhaust gas recirculation control gear of motor car engine, particularly a kind of motor car engine EGR valve.
Background technique
The EGR valve is one and is used for the electromechanical integrated product of Control and Feedback to the amount of exhaust gas recirculation of gas handling system.
At present, existing a kind of motor car engine EGR valve includes valve body, is arranged on motor, spool in the valve body; Spool cooperates with motor linkage, and move by the Spin Control spool of motor and realize opening or closing of valve, thereby for the control of valve opening; Only need to get final product through the angle of swing of control motor; General directly send signal through the master machine control unit on the automobile and control motor and rotate a certain angle, still, the control of this structure; Make that the aperture of valve is inaccurate, thereby can not control exhausted air quantity well.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of existing technology, the utility model provides a kind of motor car engine EGR valve, the aperture of control valve accurately, and then can guarantee accurate control to exhausted air quantity.
The technological scheme of the utility model: a kind of motor car engine EGR valve; Include valve body, be arranged on motor, spool in the described valve body; Described spool cooperates with motor linkage; The sensor that also includes little processing control unit and be used to detect the valve opening position; Described little processing control unit all is electrically connected with described sensor, motor, and described little processing control unit includes the host communication puocessing module, is used for the motor drive module that pick-up transducers is imported the input acquisition module of data, valve opening control computing module and is used for drive motor.
Adopt technique scheme; Through the sensor set up and the little processing control unit aperture of control valve accurately; Described host communication puocessing module is used for and the communication of vehicle main frame control unit, receives the aperture position command signal of valve, and sensor is input to the signal of the current valve opening position of being gathered in the input acquisition module; Calculate valve by valve opening control computing module and also need what open or close; Thereby drive valve core movement by the motor drive module drive motor again, accomplish the control of valve opening, the motor car engine EGR valve of this structure; The aperture of control valve accurately, and then can guarantee further setting to accurate control the utility model of exhausted air quantity: be provided with power model between described motor and the little processing control unit.
Adopt above-mentioned further setting, power model be the power electronic electrical device by certain function combinations again embedding become a module, the power model of being set up is used for protecting little processing control unit, prevents overload, short circuit or overheated and burn out.
