Device operation principle
(1) original state：
In Fig. 1 disk valve body be in open mode, motor not electric work, electronic control unit no signal input with it is defeated
Go out.
Electronic controller is in initial position in Fig. 1；Power supply opening.
(2) self-inspection before equipment work
Every time, it is necessary to be detected to equipment state, to ensure the accuracy of measurement result before experiment.In Electronic Control list
In first, there is provided self-check program, every time before experiment, electronic control unit automatically controlled after being powered dish valve progressively closed from standard-sized sheet to
It is fully closed, then recover again to standard-sized sheet, electronic signature capture unit detection valve body position simultaneously feeds back to electronic control unit, and equipment will
Have and following perform action：
1. electronic control unit output signal；
2. the electronic signature capture feedback unit that disk valve gear is progressively closed in valve block, disk valve gear according to signal is examined
Side valve piece opening amount signal feeds back to electronic control unit；
3. whether electronic control unit contrast output is consistent with feedback signal, completes a self-inspection, the time is 2s.
(3) work regulation process
During on-test, start and start after normal working of engine：
1. regulation engine speed records engine performance parameter to rotating speed is tested；
2. the corresponding admission pressure of the experimental enviroment according to needed for the normal atmospheric pressure of table 1 is checked in the height above sea level table of comparisons；
3. electronic controller is adjusted, disk valve is progressively closed off.
4. temperature, pressure sensor detection pressure reach that electronic signature capture feedback device feeds back to electronics after demand pressure
