Description
Technical field
The present invention relates to a kind of detection frock, particularly a kind of detection frock for detection of electronic EGR valve angle sensor.
Background technology
Engine exhaust-gas recirculating system (abbreviation egr system) is for reducing the discharge rate of nitrogen oxide in the waste gas, when its function mode refers to turn round under engine load, the EGR opening of valves, the small amount of exhaust gas that engine is discharged is transmitted back to inlet manifold, and enters cylinder with fresh combustion mixture and burn again.Its principle is to utilize a large amount of CO that contain in the waste gas
2, and CO
2Can not burn but can absorb a large amount of heat, and the temperature of combustion of combination gas in the cylinder is reduced, thereby reduces the growing amount of NOx, reduces exhaust pollution.
EGR valve in the egr system is mainly used in regulating the flow of control EGR gas, electronic EGR valve is by the aperture size of inner DC MOTOR CONTROL air intake opening, thereby adjusting exhaust gas flow, return cylinder after making waste gas and fresh air mixing by a certain percentage and carry out recycle, to reduce combustor inner cylinder temperature and burning rate, further reduce the discharge capacity of NOx.For pneumatic EGR valve, electronic EGR valve has the advantages that response speed is fast, operation is more stable, and electronic EGR valve can also solve the difficult problem that some vehicle does not have vacuum source, therefore uses comparatively extensive.
Electronic EGR valve is one and is installed in the electromechanical integrated product that is used for controlling the amount of exhaust gas recirculation that feeds back to gas handling system on the diesel engine that angular transducer is exactly the regulation and control product that is used for control EGR valve opening on the electronic EGR valve.Because electronic EGR valve needs the reliable and stable EGR valve opening of finishing, and the angular transducer on the electronic EGR valve is exactly the vitals of testing and control the EGR valve opening, so the signal of electronic EGR valve angle sensor output directly reflects the aperture of electronic EGR valve.
The method of the electronic EGR valve angle of detection sensor commonly used is angular transducer to be installed on the electronic EGR valve detect at present.During detection, electronic EGR valve driven wheel rotates, and the magnet steel of installing on the gear meeting driven gear that rotates simultaneously rotates, and magnet steel will rotate an angle like this, thereby changes the aperture of electronic EGR valve; Then the actual aperture of electronic EGR valve is measured, and the adjusting angle of measurement result and angular transducer output is compared; When the two is consistent, illustrate that the angular transducer performance meets the demands; When the difference between the two surpasses the error range of regulation, illustrate that angular transducer is defective.Therefore be rationality and the accuracy that guarantees that angular transducer detects in whole testing process, need constantly change the anglec of rotation of magnet steel, and then also just need constantly measure the actual aperture of electronic EGR valve, and constantly compare with the angle value of angular transducer output, not only time and effort consuming, work efficiency are low, and when needing to change angular transducer to be detected, also need be on electronic EGR valve repeated disassembled and assembled, very easily damage electronic EGR valve, cause unnecessary waste.
