Fig. 2 is the flow chart representing the process step in present embodiment 1.This process is a process in mastery routine, is the process being repeated after connecting as the key switch of not shown on and off switch.If connection key switch, then start the flow chart of Fig. 2, and petrolift 3 is driven.
First, in step 201, whether stop judging to internal combustion engine 1.Whether step 201 is the process as the halted state detector unit detecting the halted state of internal combustion engine 1, change according to the signal of speed probe 8, detect halted state.
In step 201, if being judged as, internal combustion engine 1 is in halted state, then terminate the process of Fig. 2 and do not carry out later process.If being judged as, internal combustion engine 1 is not at halted state, then advance to step 202.
Step 202 is the process as Startup time detector unit, and the situation that internal combustion engine 1 is in starting state detects.This step such as obtains the signal of speed probe 8, is less than the situation of regulation rotating speed according to the rotating speed of internal combustion engine 1, detects Startup time.
In step 202., in the case of being judged as not being Startup time, owing to internal combustion engine 1 is already at common running status, from fuel tank 2 to the fuel conduit 5 of ejector 7, enough fuel should be filled with, therefore, terminated the process of Fig. 2 and do not carry out later process.In the case of rotating speed internal combustion engine 1 being detected is in Startup time less than regulation rotating speed, advances to step 203, whether internal combustion engine 1 is in not fired state and judges.
Step 203 is the process as the not combustion supervision unit detecting the not fired state of internal combustion engine 1, according to the secondary phenomenon because internal combustion engine 1 is in not fired state, such as internal combustion engine 1 rotation speed change less than setting (maximum of the rotation speed change of internal combustion engine 1 in the case of utilizing not shown trigger to be driven), indirectly not fired state is detected.
Fig. 3 is the figure representing the signal from speed probe 8 output, is inverted to high level or low level with the crankangle of the regulation of internal combustion engine 1.In figure 3, T (n) represents this detected cycle, and T (n-1) represents the cycle detected by the last time, and these information are measured, and store them in RAM14a by each rising edge at signals of rotational speed sensor.In step 203, according to following formula (1), not fired state is detected.
[mathematical expression 1]
|T(n)-T(n-1)| ＜ T(n-1)×K1…(1)
In formula, K1 is the coefficient obtaining the threshold value that the rotating speed to internal combustion engine 1 has no change to detect, and is stored in ROM14b as control information by K1.K1 is set as at the maximum utilizing trigger to drive the rotation speed change rate in the case of internal combustion engine 1.
It addition, here, in the case of detecting that the variation of rotating speed is less than setting, it is in and utilizes trigger with the rotating speed that is held nearly constant to drive the state of internal combustion engine 1, it is thus possible to deduce the state being not at utilizing the burning of internal combustion engine 1 itself to be driven.In this case, advance to step 204, will determine that enumerator C1 carries out plus coujnt and adds 1.
It addition, in step 203, in the case of variation rotating speed being detected is more than setting, fuel ejects from ejector 7 and burns in internal combustion engine 1, is in, it is thus possible to deduce, the state that rotation speed change occurs.In this case, advance to step 205, will determine that enumerator C2 carries out plus coujnt.
In step 206, in the case of the value judging enumerator C2 is more than or equal to judgment value N2, it is judged that be continuously in, for internal combustion engine 1, the state that rotating speed is higher, and the most fully discharged the air in fuel conduit 5, advance to step 207, thus drive ejector 7 with common valve open time Tinj1.In the case of the value judging enumerator C2 is less than judgment value N2, advance to step 208.Here, discharge the time terminating, persistently internal combustion engine 1 being provided fuel according to the air being judged as in fuel conduit 5, judgment value N2 is set.
In a step 208, in the case of judging that the value of enumerator C1 is more than or equal to N1, it is judged that for being in incombustible state, being i.e. in fuel conduit 5 and there is no the state of fuel, advance to step 209.In a step 208, in the case of being judged as that the value judging enumerator C1 is less than judgment value N1, it is judged that for there is the state of fuel in being in fuel conduit 5, advancing to step 207, driving ejector 6 with common valve open time Tinj1.Here, it is judged that value N1 is for being judged as that internal combustion engine 1 is in not fired state and time of being only driven with trigger, being equivalent to several turns of required times in the case of utilizing trigger to be driven.
Step 209 is the process as amending unit, described amending unit is when internal combustion engine 1 is in Startup time and is in not fired state, with the valve open time corresponding with the rotating speed of internal combustion engine 1, carry out the driving time of ejector 6 increasing and revise, valve open time to the ejector 7 such as calculated based on above-mentioned water temperature, suction air capacity or suction nozzle internal pressure etc. is multiplied by the coefficient of regulation, is revised to carry out increasing.
Fig. 5 is using transverse axis as time, the sequential chart that represents the flow process performed according to the above description.In being in air and being filled with fuel conduit 5, there is not fuel thus only by trigger in the case of the not fired state driving internal combustion engine 1 and carrying out rotating, will determine that enumerator C1 carries out plus coujnt.Before judging that enumerator C1 reaches judgment value N1, ejector 7 is driven with valve open time Tinj1, in the case of more than or equal to judgment value N1, in order to promote that the air in fuel conduit 5 is discharged, drive ejector 7 with the time longer than valve open time Tinj1, i.e. valve open time Tinj2.
It addition, provide fuel to burn thus in the case of the change greatly of the rotation speed change of internal combustion engine 1 in internal combustion engine 1 endogenous cause of ill, will determine that enumerator C2 carries out plus coujnt.Even if causing temporarily burning because part residues in the injection of the fuel in outlet tube 6, but owing to judging that enumerator C2 is less than judgment value N2, therefore, still it is driven with the valve open time Tinj2 of ejector 7, persistently to promote that the air in fuel conduit 5 is discharged.Judgment value N2 is that the air in fuel conduit 5 is discharged it is thus possible to will become apparent from the judgment value of the rotation speed change of internal combustion engine 1, in the case of judging that enumerator C2 is more than or equal to judgment value N2, ejector 7 is driven, to prevent fuel from providing excess with valve open time Tinj1.
In step 209, in the case of burning when promoting the air in fuel conduit 5 to discharge thus cause the rotating speed of internal combustion engine 1 to rise, if driving ejector 7 with than the longest valve open time, then can eject with original startup required for fuel emitted dose compared with want excess fuel.Therefore, according to the performance plot shown in Fig. 4, shorten valve open time according to the rising of the rotating speed of internal combustion engine 1, to prevent fuel from providing excess.Additionally, after causing burning in the injection of the fuel because locally lying in, not fired state is become in air is filled with fuel conduit 5, the rotating speed of internal combustion engine 1 declines, in this case, the decline of the rotating speed according to internal combustion engine 1 extends valve open time, to promote that the air in fuel conduit 5 is discharged.
Therefore, according to embodiment 1, even just having completed the automobile after assembling, but owing to not fired state can be eliminated, promoting that the air in fuel conduit 5 is discharged, it is thus possible to shorten the time required for it starts, therefore, also can improve the operability of assembly line.
Further, since the rotation speed change of internal combustion engine 1 is detected, thus indirectly not fired state is detected, accordingly, it is capable to utilize existing sensor that not fired state is detected, and its structure can be simplified.
Further, since rise the valve open time shortening ejector 7 according to the rotating speed of internal combustion engine 1, accordingly, it is capable to avoid ejecting with original startup required for fuel quantity compared with want the fuel of fuel of excess to provide excess state, and can prevent internal combustion engine 1 from damaging.
As it has been described above, according to fuel-injection control device for internal-combustion engine involved in the present invention, owing to described fuel-injection control device for internal-combustion engine includes: Startup time detector unit, the Startup time of internal combustion engine is detected by this Startup time detector unit；Not combustion supervision unit, this not combustion supervision unit the not fired state of internal combustion engine is detected；And amending unit, this amending unit is when internal combustion engine is in Startup time and is in not fired state, the valve open time of Fuelinjection nozzle is modified, in the case of the rotation speed change of internal combustion engine is less than setting, not fired state is not detected by combustion supervision unit indirectly, therefore, though in fuel flow path footpath almost without fuel in the case of, also can start rapidly internal combustion engine.
It addition, in the case of the rotating speed of internal combustion engine changes, shorten valve open time according to the rising of rotating speed, it is thus possible to prevent fuel excess, decline according to rotating speed extends valve open time, it is thus possible to promote that the air in fuel conduit is discharged, starts rapidly internal combustion engine.
