There is phase to solidify flag bit, when engine 201 starts and detects phase solidification flag bit set, control unit of engine
206 can be according to the inclined of which circle of cam feature tooth correspondence flywheel, cam feature tooth correspondence flywheel centre tooth, camshaft and flywheel
Moving angle A OGN, oil pump solenoid valve control order and fuel injector control sequence carries out setting up rail pressure and sentences cylinder, reaches and quickly opens
Dynamic purpose, as shown in Figure 3.
When oil pump 202 is initially installed, it is necessary to pass through phase change switch 203 by the phase in control unit of engine 206
Position solidification flag bit reset, therefore, control unit of engine 206 need carry out install phase determination and obtain engine open
Dynamic information, will could realize the correct startup to engine 201 after phase solidification flag bit set.
In order to be able to the phase in control unit of engine 206 is solidified into flag bit set, control unit of engine 206 needs
Carry out the processes such as flywheel interruption, cam are interrupted, flywheel sentences cylinder and phase confirms.
As shown in figure 4, control unit of engine 206 after cam signal is received, it is necessary to output cam correlating markings position
（Described cam correlating markings position refers to the multiple tooth flag bit of cam）, and calculate the multiple tooth corresponding flywheel centre tooth of cam.Cam
Interruption starts, such as step 401, it is necessary to judge whether phase solidification flag bit is 0, phase solidification flag bit is 0 in step 402
Represent that engine 201 is the phase of new clothes, now, then the acquisition multiple tooth corresponding centre tooth of cam, such as step 403 are carried out again
Step 404, rail pressure is set up by cam control, after rail pressure is set up, is terminated whole cam and is interrupted；Control unit of engine 206 is by convex
The process that wheel controls to set up rail pressure is the conventional process of the art, is specifically repeated no more.When phase solidification flag bit is not 0
When, then it represents that engine 201 is not new clothes phase, then need sentence whether cylinder flag bit is 1 to be sentenced according to step 405
It is disconnected, when it is 1 to sentence cylinder flag bit, then it represents that cylinder current in engine 1 determines, then needs to be judged according to step 406
Cam sentences whether cylinder flag bit is 1, and it is 1 to sentence cylinder flag bit when cam（Cam sentences cylinder flag bit for 1 expression is sprayed according to cam
Oil pump oil control, flywheel signal is abnormal）When, then cam control pump oil and oil spout are pressed into step 407, otherwise, terminate cam
Interrupt routine.When it is not 1 to sentence cylinder flag bit, then cam control rail pressure is pressed into step 408 step.Pressed into step 408
During cam control rail pressure, judge whether flywheel signal is normal, such as step 409, when flywheel signal is normal, terminates cam and interrupt journey
Sequence, otherwise, in flywheel abnormal signal（Flywheel abnormal signal mainly includes flywheel dropout or has interference）Shi Yizhao steps 410
Sentence cylinder mark position 1, it is 4 to sentence cylinder type（It is described to sentence cylinder type for 4 expressions carry out oil spout pump oil control according to cam）, cam sentences
Cylinder mark position 1.
As shown in figure 5, control unit of engine 206 receives flywheel signal, output flywheel correlating markings position（The flywheel
Correlating markings position refers to the number of teeth after flywheel hypodontia and flywheel hypodontia）, then control unit of engine 206 is according to flywheel signal of change
Go out to sentence cylinder first window limit value, sentence cylinder the second window limit value.Usually, window calculation be on the basis of flywheel centre tooth, plus
The scope obtained after a tooth that subtracts two is exactly window.
Specifically, during step 501, flywheel is interrupted and started；When step 502 is entered, flywheel motor synchronizing is judged（The flywheel
Motor synchronizing is to have found hypodontia）, after flywheel motor synchronizing is judged, into step 503, cylinder window limit is sentenced to carry out calculating
Value, otherwise, terminates flywheel interrupt routine.After computationally stating window limit value, into step 504, it is to sentence cylinder flag bit
No is 1, is 1 when cylinder flag bit is sentenced（Here it is by carrying out set in cam interrupt step 410 to sentence cylinder flag bit）When, according to
Step 505 enters the acknowledged journey of line phase, and oil spout pump oil control is carried out further according to step 506；When it is not 1 to sentence cylinder flag bit, enter
Row flywheel sentences cylinder process, such as step 507, after step 506 or step 507, terminates flywheel interrupt routine.
As shown in fig. 6, sentencing the flow chart of cylinder for flywheel, step 601 is sentenced cylinder and is started for flywheel, in step 602, to flywheel
0 tooth be assumed to be the first cylinder, in step 603, to sentencing cylinder flag bit set（1 is put, all of set is and puts in the present invention
1）.In step 604, judge whether cam is normal, when cam is normal, into step 605, to sentencing cylinder in window ranges（It is described
Whether it is to judge there is the multiple tooth appearance of cam in flywheel window ranges that cylinder is sentenced in window ranges）, it is 1 or 2 to sentence cylinder type（Window
In the range of have cam multiple tooth to be exactly 1, be otherwise 2）, then step 606 adjustment Injection Control sequentially；When cam is abnormal（Typically
Ground, cam is abnormal to be referred to cam broken string or has interference）When, then assume to sentence cylinder mark position 1 in step 607（Sentence cylinder flag bit
Put 1 comprise provide that with non-hypothesis state, here after assuming that sentencing cylinder mark position 1, mean that real single flywheel signal hypothesis
Sentence cylinder）, it is 3 to sentence cylinder type（Cylinder type is sentenced for 3 represent that single flywheel is assumed to sentence cylinder state）, tied after step 607 and step 606
Beam flywheel sentences the flow of cylinder.
As shown in fig. 7, being the flow of phase confirmation.Step 701 is that phase confirms to start, and in step 702, judges that phase is true
Recognize whether flag bit is 1, when phase acknowledgement indicator position is 1, then terminates phase and confirm flow.When phase acknowledgement indicator position is not
When 1, into step 703, judge whether cam signal is abnormal, when cam signal is abnormal, then perform the solo flight of step 704
Terminate phase after wheel phase confirmation process and confirm flow, the dual signal phase for otherwise performing step 705 confirms process.In step
After 705, judge whether phase acknowledgement indicator position puts 1 and whether phase solidification flag bit is 0.When phase acknowledgement indicator position is not 1
Or phase solidification flag bit not be 0 when, then terminate phase confirm flow.When phase acknowledgement indicator position is 1 and phase solidification mark
When position is 0, just phase solidifies mark position 1, and stores the number of turns, flywheel centre tooth and the AOGN of the multiple tooth correspondence flywheel of cam
Deng engine start information.
Specifically, in the case of phase does not confirm, i.e., step 702 is invalid for control unit of engine 206, that is, need into
The step of line phase confirms.When phase acknowledgement indicator position is not 1 and abnormal cam signal, i.e., single flywheel is assumed to sentence cylinder rank
Section, process is confirmed into single flywheel phase.Single flywheel phase confirmation during, according to setting cycle of engine in, engine
Whether rotating speed or rail pressure have decline, sentence the correctness of cylinder, when engine speed or rail pressure drop to setting value, then it is assumed that
It is wrong to sentence cylinder, otherwise it can be assumed that the result for sentencing cylinder is normal.
If cam signal is normal, process is confirmed into dual signal phase.During the confirmation of dual signal phase, specially
Phase solidifies and uncured（Phase solidification is to represent to confirm to installing phase）Two methods, if phase is not solid
Change, according in certain cycle of engine, whether engine speed or rail pressure have decline, sentence the correctness of cylinder；If phase
Position solidification, according in certain continuous cycle of engine, window verification correctness sentences the correctness of cylinder.
During phase confirmation, if phase acknowledgement indicator position is 1 and phase solidification mark position 1, storage cam is special
Levy the tooth correspondence flywheel number of turns, centre tooth, AOGN deviation angles, oil spout pump oil order etc..
In the course of the work, the switching of flywheel and cam work benchmark can also be realized（The switching is to sentence cylinder type 4
With sentence the switching between cylinder Class1 or 2）, as shown in Figure 8.Step 801 is that working standard switching starts, and step 802 carries out cam
Sentencing cylinder will judge whether cylinder flag bit is 1, when it is 1 to sentence cylinder flag bit, then judge phase acknowledgement indicator position into step 803
Whether it is 1, when phase acknowledgement indicator position is 1, then cam is sentenced into cylinder flag bit in step 805 and reset, then terminates switching stream
Journey.When phase acknowledgement indicator position is not 1, cam is judged either with or without motor synchronizing into step 806, when cam motor synchronizing, then
Into again to tooth the step of 808, otherwise when cam does not have motor synchronizing, terminate switching flow.
When cam sentence cylinder flag bit be 1 when, then into step 804 judge flywheel whether motor synchronizing, when flywheel motor synchronizing
When, terminate switching flow.When flywheel does not have motor synchronizing, then into step 807 judge cam whether motor synchronizing, when cam from together
During step, into step 809, the cylinder mark position 1 of sentencing of cam is reset to phase acknowledgement indicator position simultaneously, when the non-motor synchronizing of cam
When, then into step 810, to carry out again to tooth, then terminate switching flow.
Specifically, if being currently to control oil spout pump oil by flywheel, it is not 1 that cam sentences cylinder flag bit, if flywheel does not have
Motor synchronizing and cam synchronization, then perform step 809, and cam sentences cylinder mark position 1, phase acknowledgement indicator position clear 0；If flywheel and
Cam is all without motor synchronizing（The all no motor synchronizing of the flywheel, cam is that flywheel does not find hypodontia, and cam does not find many
Tooth）, then into again to tooth the step of 810.If being currently to control oil spout pump oil by cam, step 803 is entered back into, judge phase
Whether position acknowledgement indicator position is 1, when phase acknowledgement indicator position is 1, then performs step 805, and cam is sentenced into cylinder flag bit clear 0
（Described cam sentences cylinder flag bit when being controlled by flywheel, and it is 1 to sentence cylinder flag bit, and it is 0 that cam sentences cylinder flag bit；Press cam control
When processed, it is 1 to sentence cylinder flag bit, and it is also 1 that cam sentences cylinder flag bit）；If phase acknowledgement indicator position is not 1, and cam is without certainly
It is synchronous, into again to tooth（Restarting is equivalent to tooth again）The step of 808.
After Fig. 9 shows phase change, step 902 carries out initialization operation to correlated variables.
Current cylinder scheme of sentencing only concentrates on the determination of oil spout phase, without considering oil pump（Particularly inline pump）Control
System, rail pressure sets up slow influence toggle speed, current to sentence cylinder scheme big multipair mechanical structure and change than larger, and install will
Ask comparing strict.
In first time start-up course, automatic identification obtains and phase is installed between oil pump 202 and bent axle the present invention, and by phase
In control unit of engine 206, startup is used after being provided with for position relevant information analysis storage, therefore between oil pump 202 and bent axle
Installation it is without any requirement, substantially reduce installation difficulty and installation cost.Control unit of engine 206 is obtaining installation phase mistake
