Description
Technical field
The utility model relates to engine exhaust emission recirculating system technical field, particularly a kind of device for calibrating throttle position switch initial position.
Background technology
In engine exhaust-gas recirculating system (egr system), throttle position switch is mainly used in the signal into ECU input engine throttle size, ECU calculates the aperture of current EGR systems demand according to throttle position switch signal and the signal such as rotating speed, water temperature by meter reading method, utilize the signal calculated to control the aperture size of EGR valve, thus adjustment exhaust gas flow, return cylinder after waste gas is mixed by a certain percentage with fresh air and carry out recycle, temperature and burning rate is burnt, further thus reduce NO to reduce cylinder combustion
xdischarge capacity.
The China of state three emission limit is implemented at current non-rice habitats, the technology path of most of non-rice habitats diesel engine producer is that mechanical type injection pump adds egr system, mechanical type injection pump is be not with throttle position switch when dispatching from the factory, so when engine assembles online, need to install throttle position sensor bracket and throttle position switch in addition, this just relates to accelerator open degree size and the conforming problem of initial position.
In the method determined throttle position switch initial position be at present: in engine calibration process, on the engine throttle position switch is installed, engine is in idling mode (i.e. minimum throttle position), is adjusted the initial angle of throttle position switch by position signalling position machine on computers reading throttle position switch; The method carries inconvenience, and wiring is loaded down with trivial details, and adjustment is difficulty comparatively, and needs at least two people's compounding practices just can complete, not only inefficiency, and initial position calibration accuracy is poor.
Summary of the invention
The utility model technical issues that need to address are to provide a kind of simple to operate, easy to carry, accurately can determine the calibrating installation of throttle position switch initial position when engine is produced in batches.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
Throttle position switch initial position calibrating installation, comprise housing, 5V accumulator is provided with in described housing, the upper surface of housing is embedded with power switch and the digital display type voltage table for detecting throttle position switch voltage signal, the sidewall of housing is provided with one end connection voltage table is connected throttle position switch throttle position switch plug with accumulator, the other end.
Above-mentioned throttle position switch initial position calibrating installation, is also provided with the 5V charge power supply be connected with 5V accumulator in described housing.
Owing to have employed above technical scheme, acquired by the utility model, technical progress is as follows.
The utility model is applied to mechanical pump diesel engine and installs additional in egr system, accurately can determine needing the initial position of the throttle position switch installed, and effectively ensure that the consistance of throttle signal during later stage engine batch production.Adopt the utility model, only when installing throttle position switch, device need be opened, plug is inserted on throttle position switch, twist throttle position transducer, by throttle position switch angular setting to minimum, now the feedback voltage of throttle position switch is the voltage of throttle initial position; As this magnitude of voltage exceeds error range, then adjusted within initial position voltage error scope by the feedback voltage of throttle position switch by the adjustment knob on adjustment throttle position switch, initial position voltage is generally decided to be 0.8V ~ 1.2V; Locking positioning nut after adjusting to specialized range, takes out sensor plug and namely calibrates complete.
Accompanying drawing explanation
Fig. 1 is the wiring diagram of the utility model using state.
Wherein: 1. 5V accumulator, 2. digital display type voltage table, 3. throttle position switch plug, 4. 5V charge power supply, 5. power switch, 6. throttle position switch.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
A kind of throttle position switch initial position calibrating installation, comprise housing, the output terminal being provided with 5V accumulator 1 and 5V charge power supply 4,5V charge power supply 4 in housing is connected with 5V accumulator 1; The upper surface of housing is embedded with power switch 5 and digital display type voltage table 2, and digital display type voltage table 2 is for detecting and showing throttle position switch voltage signal; The sidewall of housing is provided with throttle position switch plug 3, one end that throttle position switch plug 3 is positioned at housing connects voltage table and accumulator, and the other end of throttle position switch plug 3 connects throttle position switch.
In the present embodiment, housing is can the plastic housing of single-hand held; Digital display type voltage table range is 0 ~ 5V; Throttle position switch plug is the wire harness of the plug that 80 centimeters of long band and throttle position switch socket match.
The utility model in use, only throttle position switch plug need be plugged on throttle position switch to be tested, the calibration loop be made up of 5V accumulator, power switch, digital display type voltage table and throttle position switch can be formed, as shown in Figure 1, turn on the power switch and can calibrate.
In test process, the magnitude of voltage of current throttle position sensor can be read by the voltage table observed on housing quickly and accurately, thus judge that whether the initial position of throttle position switch is accurate; As inaccurate, operating personnel only the utility model need be placed on side simultaneously twist throttle position transducer angle just a people can complete the initial position calibration operation of throttle position switch.In addition, this calibrating installation also can detect throttle position switch accurately non-fault.
Application of the present utility model, instead of when traditional oils door position sensor is installed and uses physical angle as the method for reference, not only measures more accurate, more can ensure the consistance of initial position, and easy to carry, simple to operate, with low cost.
