Description
Technical field
The present invention relates to engine detection field, more particularly to a kind of OCV OCV Oil Control Valves detection method.
Background technology
Engine completion assembling is offline, mounting technology and parts quality is considered without any, by engine ignition
Heat examination can check engine with the presence or absence of the straight-forward phenomenons such as abnormal sound and leak gas leak of the oil leakage, but to OCV machines in whole process
Oil control valve can not detect whether catching phenomenon occur；
Because of the promotion of engine production production capacity, heat examination rack is also substantially consistent on capacity planning with assembly line,
Place in the case that ensure engine production production capacity, the heat examination operating mode to engine is concrete regulation, and also must assure that institute
Produce the quality of engine.
Hot-firing test rack belongs to not on-load and operating inspection is carried out to engine, so the highest of entire engine turns
Speed does not exceed 3000 revs/min, and OCV OCV Oil Control Valves operating condition in ECU calibration is that the operating mode of engine is 3000
Turn or more, throttle opening is more than 90%.So under the idling and high warming-up operating mode that are run on heat examination rack, OCV is not
It can work, so can not check whether OCV OCV Oil Control Valves can be normally-open with closing.So engine manufacture is packed into
In vehicle, in the case where reaching specified operating mode, if OCV OCV Oil Control Valves are not opened, timing variation and air inflow can not be realized
Optimum condition state is not achieved in control, engine.Car will appear bad Acceleration, and power is inadequate, the bad phenomenons such as flame-out
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of OCV OCV Oil Control Valves detection methods, are used for
Whether normal detect OCV OCV Oil Control Valves.
To achieve these goals, the technical solution adopted by the present invention is：A kind of OCV OCV Oil Control Valves detection method is led to
It crosses hot-firing test rack and operating detection is carried out to engine；
When engine works, it is powered to OCV OCV Oil Control Valves, observes the working condition of engine, stop later to OCV
OCV Oil Control Valve is powered, and observes engine behavior；
If shaking occurs in engine when being powered and jitter conditions disappear when power is off, judge that OCV machine oil controls at this time
Valve is normal；Otherwise, OCV OCV Oil Control Valves are faulty.
Engine working condition on igniting experiments rack is engine idling condition.
Power supply is by switching control as OCV OCV Oil Control Valve power on/off.
The 12V voltages of power supply output are input to through switch control in OCV OCV Oil Control Valves.
The advantage of the invention is that：Engine work is detected on igniting experiments rack, by giving OCV OCV Oil Control Valves defeated
Enter 12V voltages actively to open, and closing 12 control sources later, when observation accesses 12 voltage and after closing 12V voltages
Engine jitter conditions judge the fault condition of OCV Oil Control Valve, overcome engine ignition experimental stand that can not detect with this
The defects of OCV OCV Oil Control Valves, and this method is easy to operate, and exploitativeness is strong.
Description of the drawings
Label in each width attached drawing is expressed to description of the invention below content and figure is briefly described：
Fig. 1 is structure principle chart of the present invention.
Specific embodiment
Below against attached drawing, by the description to optimum embodiment, the specific embodiment of the present invention is made further detailed
Thin explanation.
A kind of OCV OCV Oil Control Valves detection method carries out operating detection by hot-firing test rack to engine；Starting
When machine works, it is powered to OCV OCV Oil Control Valves, observes the working condition of engine, stop leading to OCV OCV Oil Control Valves later
Electricity observes engine behavior；If when being powered, shaking occurs in engine and jitter conditions disappear when power is off, sentence at this time
Disconnected OCV OCV Oil Control Valves are normal；Otherwise, OCV OCV Oil Control Valves are faulty.
Hot-firing test rack belongs to not on-load and operating inspection is carried out to engine, so the highest of entire engine turns
Speed does not exceed 3000 revs/min, and OCV OCV Oil Control Valves operating condition in ECU calibration is that the operating mode of engine is 3000
Turn or more, throttle opening is more than 90%.So under the idling and high warming-up operating mode that are run on heat examination rack, OCV is not
It can work, so can not check whether OCV OCV Oil Control Valves can be normally-open with closing.In order to make its work, here
By the force start OCV OCV Oil Control Valves for being manually passed through 12V voltages.
12 power supplys connect manual switch by rigid line, and manual switch is adapted by rigid line and with solenoid valves port
Interface connect with OCV OCV Oil Control Valves, manual switch is for controlling whether electric power output voltage can be connected.Then will start
Machine, which is placed on hot-firing test rack, detects operating, and operation mode is idling operation pattern, is then operated with manual switches and connects 12V
Power supply, 12V control source OCV OCV Oil Control Valves observe the jitter conditions of engine at this time, are then turned off switching, and disconnect 12V electricity
The jitter conditions of engine at this time are observed in pressure input.The operating condition and access failure under idling operation by checking engine
The state of 12V voltages is compared, if in the case where OCV OCV Oil Control Valves connect 12V voltage conditions, serious shake occurs in engine
Situation, when closing output voltage, engine jitter phenomenon disappears；If engine goes out after OCV OCV Oil Control Valves access 12V voltages
Now serious jitter conditions and after 12V voltages are disconnected, jitter phenomenon disappear, then ocv OCV Oil Control Valves are normal at this time, otherwise have
Failure.
OCV OCV Oil Control Valves belong to solenoid valve, and when inputting 12V voltages, internal spool is acted, and machine oil flows into
VVT controls advance chamber or retard chamber, changes the air inflow of original normal idling, in the case where abnormal conditions occurs in air inflow, starts
It is more or few that machine combustion chamber will appear air inflow, then in the case where distributive value is certain, occurs burning insufficient or gaseous mixture not
Fully, there is serious shake in engine.Therefore, it when inputting 12V voltages, if OCV OCV Oil Control Valves work normally, can produce
Thus the shake of hair tonic motivation judges whether OCV OCV Oil Control Valves are normal.Heat examination rack not on-load, more than 3000 revs/min
Clock runs at high speed there are risk, but is unable to reach OCV OCV Oil Control Valve operating conditions, and whether the OCV of appearance is worked normally,
It can not judge.By understanding the operation principle of OCV, using rack for electric resources, force under declared working condition, OCV is allowed to carry out work
Make, come detect whether can it is normally-open with close, it is only necessary to judge whether engine is shaken and can determine whether, this method make letter
It is single, it is easy to operate, and to product component quality control, reduce market quality problem.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as employing the methodology and skill of the present invention
The improvement for the various unsubstantialities that art scheme carries out, within protection scope of the present invention.
