Further, in the intake port 7, a port injection fuel injection valve 9 for injecting fuel toward the inside of the intake port 7 as an auxiliary fuel injection valve is disposed for each cylinder.
- Each of the in-cylinder injection fuel injection valve 8 and the port injection fuel injection valve 9 is an electromagnetic or piezoelectric injection valve that opens when a drive pulse signal is applied. An amount of fuel substantially proportional to the pulse width is injected.
- an electronically controlled throttle valve 14 On the upstream side of the collector portion 12 of the intake passage 11 connected to the intake port 7, an electronically controlled throttle valve 14 whose opening degree is controlled by a control signal from the engine controller 13 is interposed.

Based on these detection signals, the engine controller 13 optimally controls the fuel injection amount and injection timing by the fuel injection valves 8 and 9, the ignition timing by the spark plug 6, the opening degree of the throttle valve 14, and the like.
- FIG. 2 shows the in-cylinder injection occupying the total injection amount (that is, the sum of the in-cylinder injection injection amount and the port injection injection amount) in the operating region of the internal combustion engine 1 using the load and rotational speed of the internal combustion engine 1 as parameters.
- DIG means in-cylinder injection by the in-cylinder injection fuel injection valve 8
- MPI means port injection by the port injection fuel injection valve 9.
- the injection amount ratio of in-cylinder injection is 100% in the low-speed low-load region (that is, the entire required fuel amount is injected from in-cylinder injection fuel injection valve 8).
- the high speed / high load side region the state in which both are used in combination at a predetermined ratio, for example, the injection amount ratio of in-cylinder injection becomes about 70%.
- the injection amount ratio of in-cylinder injection tends to be lower.
- the engine controller 13 determines the necessary injection amount of the in-cylinder injection fuel injection valve 8 and the injection amount of the port injection fuel injection valve 9 in accordance with the characteristics as shown in FIG. FIG. 2 shows the characteristics after the completion of warm-up of the internal combustion engine 1, and when the engine is cold, the characteristics of the injection amount ratio of both are corrected based on the engine temperature, for example, the cooling water temperature.
- a plurality of control maps assigned to appropriate characteristics for each cooling water temperature may be provided.
- the injection amount ratio at the time of fuel cut recovery after fuel cut is corrected for a predetermined period on the premise of the control of the injection amount ratio as described above. That is, during the fuel cut, since the intake air flows without combustion in the cylinder, the temperature of the combustion chamber wall (specifically, the temperature of the cylinder wall surface and the piston crown surface) falls relatively rapidly. Therefore, in the in-cylinder injection, the fuel injected into the cylinder easily adheres to the wall surface, which causes an increase in the amount of emission of particulate matter. In the present invention, in order to suppress the discharge of such particulate matter, the reduction correction of the injection amount ratio of the in-cylinder injection is performed at the time of recovery.
- FIG. 3 is a flow chart showing the flow of control executed by the engine controller 13 according to one embodiment.
- step 1 it is determined whether fuel cut has already been started, in other words, whether fuel cut is in progress. Assuming that the driver fully closes the accelerator pedal opening while the vehicle is traveling, predetermined fuel cut conditions (for example, the cooling water temperature has been warmed up, the vehicle speed is equal to or higher than a predetermined threshold, the engine rotational speed Is equal to or greater than a predetermined threshold value, etc.) and the fuel cut is performed.
- predetermined fuel cut conditions for example, the cooling water temperature has been warmed up, the vehicle speed is equal to or higher than a predetermined threshold, the engine rotational speed Is equal to or greater than a predetermined threshold value, etc.
- step 12 the process proceeds to step 12 to perform normal fuel injection control. That is, the injection amount of the in-cylinder injection fuel injection valve 8 and the injection amount of the port injection fuel injection valve 9 are controlled in accordance with the characteristic of the injection amount ratio as shown in FIG.
- step 2 If it is in the fuel cut, the process proceeds to step 2, and the fuel cut time is measured using the counter FCTCNT indicating the fuel cut period.
- step 3 based on the value of the counter FCTCNT in step 2, a first set value TFCRDIDTA of the in-cylinder injection decrease correction period is obtained from the table of characteristics as shown in FIG.
- the first set value TFCRDIDTA increases as the fuel cut time increases.
- the process proceeds to step 4 to estimate the combustion chamber wall temperature CCWTEMP.
- the combustion chamber wall temperature CCWTEMP during engine operation can be estimated using parameters such as the load and rotational speed of the internal combustion engine 1 and, if necessary, the coolant temperature and the intake temperature.
- the combustion chamber wall temperature CCWTEMP during the fuel cut is obtained by successively subtracting the temperature decrease from the estimated temperature at the start of the fuel cut using the intake amount and the intake temperature passing through the combustion chamber during the fuel cut. Estimation is possible.
- the method of estimating the combustion chamber wall temperature CCWTEMP is not limited to the above example, and any method may be used. Alternatively, the combustion chamber wall temperature may be directly detected.
- step 5 based on the combustion chamber wall temperature CCWTEMP estimated in step 4, a second set value TFCRDIDTB of the in-cylinder injection decrease correction period is obtained from the table of characteristics as shown in FIG.
- the second set value TFCRDIDTB becomes larger as the combustion chamber wall temperature CCWTEMP is lower.
- step 6 the first set value TFCRDIDTA of step 3 is compared with the second set value TFCRDIDTB of step 5, and the larger value is determined as the set value TFCRDIDT of the in-cylinder injection decrease correction period. Do.
- steps 2 to 6 described above are repeatedly performed during the fuel cut.
- the set value TFCRDIDT of the in-cylinder injection decrease correction period according to the fuel cut time up to that time and the combustion chamber wall temperature CCWTEMP at that time is sequentially calculated.
- step 7 it is determined whether fuel cut recovery has started. That is, it is determined whether a predetermined fuel cut recovery condition is satisfied. For example, as the fuel cut recovery condition, in addition to the depression of the accelerator pedal by the driver, the vehicle speed may be reduced to a predetermined threshold or less, or the engine rotational speed may be reduced to a predetermined threshold or less.
- step 7 the process proceeds from step 7 to step 8, and the ratio of the injection amount of in-cylinder injection to the total injection amount is corrected to decrease, and fuel supply is performed. That is, although the basic injection amount ratio is determined as shown in FIG. 2 based on the load (intake air amount) at that time and the engine rotational speed, the injection amount ratio of in-cylinder injection is higher than this basic injection amount ratio. Each injection quantity is determined so that the injection quantity ratio which made low becomes.
- the injection amount ratio after correction can be determined by subtracting a predetermined amount from the basic injection amount ratio of in-cylinder injection, or multiplying the basic injection amount ratio by a predetermined correction coefficient.
- the degree of correction (for example, the subtraction amount or correction coefficient) at this time may be a fixed value, or may be variably given according to some parameter such as a fuel cut time.
- step 9 the in-cylinder injection decrease correction period is measured using a counter FCRDIDT that indicates an elapsed period from the start of recovery.
- step 10 the value of the counter FCRDIDT is compared with the set value TFCRDIDT of the in-cylinder injection decrease correction period set in step 6. Then, when the value of the counter FCRDIDT becomes equal to or larger than the set value TFCRDIDT, the process proceeds to step 12 and returns to the normal fuel injection control. Until the set value TFCRDIDT is reached, the process returns to step 8 and the decrease correction of the injection amount ratio of the in-cylinder injection is continued.
- step 11 it is determined whether or not the combustion chamber wall temperature CCWTEMP (which is continuously estimated after recovery in step 4) becomes equal to or higher than a predetermined temperature TCCWTEMP during the in-cylinder injection decrease correction period. judge. Since the combustion chamber wall temperature CCWTEMP rises due to the resumption of fuel supply, the injection amount ratio of in-cylinder injection when the combustion chamber wall temperature CCWTEMP reaches a predetermined temperature TCCWTEMP before the value of the counter FCRDIDT reaches the set value TFCRDIDT. End the reduction correction of step S.sub.2 and return to the normal fuel injection control of step S12.
- the predetermined temperature TCCWTEMP is, for example, about 140 ° C.
- the setting value TFCRDIDT of the above-described in-cylinder injection decrease correction period is also set at a time when the actual combustion chamber wall temperature returns to about 140 ° C.

- the engine speed gradually decreases.
- the temperature of the combustion chamber wall gradually decreases.
- the fuel cut duration is measured by the counter FCTCNT.
- fuel cut recovery is performed based on recovery conditions such as a decrease in vehicle speed to a threshold, for example.
- the set value TFCRDIDT of the in-cylinder injection decrease correction period is determined based on the combustion chamber wall temperature CCWTEMP and the fuel cut time (counter FCTCNT) at the time of recovery. Then, during the in-cylinder injection decrease correction period from the start of recovery, as shown in (f) and (g) in the figure, the injection amount ratio of in-cylinder injection is given low, and the injection amount ratio of port injection is high. Given.
- the broken line indicates the basic normal characteristics as shown in FIG.
- the in-cylinder injection decrease correction period (counter FCRDIDT) reaches the set value TFCRDIDT, and the correction of the injection amount ratio ends. Thereafter, control is performed to a normal injection amount ratio.
- a so-called rich spike is given to quickly recover the catalyst device 19 from an oxygen excess state, and the equivalence ratio temporarily becomes rich. This rich spike is not necessarily continued until time t3.
- the particle number PN As described above, by reducing and correcting the injection amount ratio of in-cylinder injection during the time t2 to t3 after the fuel cut recovery, the amount of emission of particulate matter at the time of recovery is suppressed.
- the broken line in (h) of the figure shows the characteristic of the number of particles PN when the recovery is performed without correcting the injection amount ratio, and the solid line shows the case where the injection amount ratio is corrected as in the above embodiment. Shows the characteristics of the particle number PN. As shown in the drawing, at the time of fuel cut recovery, the particle number PN increases as the combustion chamber wall temperature decreases, but in the above embodiment, the particle number PN is corrected by decreasing the injection amount ratio of in-cylinder injection. Increase is suppressed.
- the combustion chamber wall temperature CCWTEMP rises as shown in the figure after recovery starts, and at time t3 when the value of the counter FCRDIDT reaches the set value TFCRDIDT, many particulate matter is generated even by in-cylinder injection. It has reached a sufficient temperature not to be generated.
