Abstract

PURPOSE:To prevent the occurrence of torque shock during slow acceleration, by a method wherein when fuel feed is restored from a deceleration running state in which the feed of fuel is stopped, a current amount of a change in a throttle opening is detected, and fuel feed is restored at a rate of change in an increase amount which is increased as an amount of a change is increased. CONSTITUTION:When the deceleration state of an engine is detected by a deceleration detecting means 4, a fuel feed stop means 5, stopping the feed of fuel from a fuel feed means 3, is provided. A fuel feed restoring means 7 is provided for releasing a stop of fuel feed, effected by a fuel feed stop means 5, when a deceleration release detecting means 6 detects that an engine is released from a deceleration state. The fuel feed restoring means 7 is also adapted to output a signal to a fuel feed means 3 so that fuel is fed in a given rate of change so as to satisfy demand fuel. The rate of change is corrected by a rate of change correcting means 9 so that the more an amount of a change in a throttle opening detected by a throttle opening change amount detecting means 8 is increased, the more the rate of the change is increased.

(Prior Art) Conventionally, an engine fuel control device has stopped the supply of fuel during deceleration operation, and when restoring the fuel supply from the fuel supply stop state, it has gradually stopped the fuel supply in order to reduce the shock. A technique for increasing and returning to normal is known, for example, as seen in Japanese Patent Publication No. 56-38781.

(Problem to be Solved by the Invention) However, in the device that stops fuel supply during deceleration operation as described above, when transitioning from deceleration operation state to acceleration operation state, fuel is gradually supplied at a constant increase rate. If you perform a return, torque shock may occur during slow acceleration,
There is a possibility that the acceleration performance during sudden acceleration may be insufficient.

In other words, for example, if the degree of increase in m at the time of return is set in accordance with a sudden acceleration state, the fuel supply amount will suddenly increase during slow acceleration, and in addition to the torque shock caused by just starting fuel supply, a large torque will be generated. A shock occurs. On the other hand, if the degree of retraction at the time of return is set in accordance with the slow acceleration state, the increase in fuel value relative to the required fuel amount will be delayed during sudden acceleration, resulting in a decrease in acceleration response.

Next, the operation of the control unit 26 will be explained based on the flowchart shown in FIG. This flowchart only shows a fuel control routine for returning fuel from a fuel supply stop state during deceleration. After the start, various signals such as throttle opening TV and engine rotation speed N are read in step S1, and based on these signals, it is determined in step S2 whether or not the fuel cut zone is reached. This fuel cut zone is a region where the throttle opening degree TV is fully open and the engine speed N is a predetermined value (for example, 2000 rpm or more).

Then, when the operating state is in the fuel cut zone and the determination in step S2 is YES, it is determined in step S3 whether or not the state has transitioned to an acceleration state. This determination is made based on whether the current throttle opening degree TV is larger than the previous throttle opening degree Tvo, and the determination in step S3 is made when the throttle opening degree TV shifts to an acceleration state in which it is operated in an increasing direction. When becomes YES, the timer value CE is counted in step S4. This counting of the timer value CE continues N times until the determination in step S2 or step S3 becomes No and the timer ffl CE is reset in step S5.

Step S6 is to determine whether or not the throttle opening degree TV has reached a predetermined opening degree TV1 or more, and this predetermined opening degree TVs is set, for example, to the timing when an idle switch that closes when the throttle is fully opened opens. , the determination is made in response to whether the idle switch is on or off. Then, the idle switch is turned off when the throttle opening TV reaches the predetermined opening TVr), and the determination in step S6 is YES.
When S is reached, the timer value GE counted in step S4 is read in step S7, and this timer value GE is

The timer value CE corresponds to the time required for the throttle opening TV to be opened to a predetermined opening TV t, and the smaller the value, the more rapid acceleration is required;
Correspondingly, the fuel return gradient C is set to a large value when the timer value CE is short, and the rate of increase in the pulse width becomes large.

is supplied, and then, based on the gradient C, a required injection pulse T2. corresponding to the operating state is supplied. Until the value corresponding to T3 is reached, the amount of fuel is increased at a large rate of change as shown by the broken line A during rapid acceleration, and at a small rate of change as shown by the solid line B during slow acceleration. Thereby, the fuel can be increased ω in accordance with the acceleration state corresponding to the amount of change in the throttle opening, and fuel control can be executed in accordance with the required output characteristics. Incidentally, the fuel amount may be increased gradually based on the gradient C from the beginning when the fuel supply is restored.
