たものは知られてる。 Conventionally, as disclosed in Utility Model Application Publication No. 54-124822, etc., a fuel control device for such an engine has conventionally been used, which supplies an increased amount of fuel to the engine during high-load operation when the engine load exceeds a predetermined value. hand,
Engines designed to improve engine output are known. In addition, as disclosed in Japanese Patent Publication No. 54-27490, for example, when the engine accelerates at a preset value or higher, an increased amount of fuel is supplied to the engine to prevent deterioration of acceleration performance due to fuel delay. Engines that are designed to improve the output of the engine are also known.

顕著であつた。 However, as mentioned above, in an engine equipped with a dual fuel control function to increase the amount of fuel during high load operation and acceleration operation, the intended function is not performed during high load operation or acceleration operation. However, during high-load operation and acceleration operation, the fuel increase during both operations overlaps, resulting in an overbalance of the air-fuel ratio, resulting in an air-fuel ratio that is much richer than the output zone, which actually reduces the output. There was a problem that caused a decline. In particular, the above-mentioned problem was noticeable when the air-fuel ratio was set to the rich side in order to prevent dissolution of the exhaust gas purifying catalyst installed in the exhaust system of the engine during high-load operation.

向上等が図れない。 Therefore, in the present invention, when increasing the amount of fuel mentioned above, the acceleration increase rate is determined by the amount for preventing acceleration deterioration due to fuel delay, that is, the fuel delay replenishment Q 1 and the output improvement amount Q 2 required for acceleration, and Considering that the increase rate is determined by the output improvement Q 3 required for high load, and that the above required output improvement Q 2 for acceleration is smaller than the above required output improvement Q 3 for high load, Originally, this was done by focusing on the fact that the fuel increase rate required during high-load operation and acceleration operation is the sum of the fuel delay replenishment Q 1 for acceleration and the required output increase Q 3 for high load. It is something. Therefore, in the acceleration increase operation region and the high load increase operation region, the above-mentioned increases Q 1 , Q 2 , Q 3
If the amount is increased by adding (Q 1 + Q 2 + Q 3 ), the amount will be overloaded than the original required amount (Q 1 + Q 3 ), and it will be necessary to increase the amount at an accelerated rate (Q 1 + Q 2 ) or increase the amount under high load (Q 3 ).
If any one of them is stopped, the amount will not be increased enough to improve the output.

に確保される。 Next, the operation of the above embodiment will be explained.
During normal operation of the engine, the basic injection pulse signal from the basic injection pulse generation circuit 30 corresponding to the output of the air flow sensor 4 is directly transmitted to the fuel injection valve 5.
Therefore, an amount of fuel corresponding to the amount of intake air is injected from the fuel injection valve 5 and supplied to the engine 1, thereby ensuring good driving performance during normal operation.

好に確保することができる。 On the other hand, during high-load operation of the engine, the increase correction circuit 31 changes the basic injection pulse signal from the basic injection pulse generation circuit 30 according to the output of the air flow sensor 4 to the first increase rate signal according to the output of the high-load sensor 7. Since the fuel injection valve 5 is operated and controlled by the injection pulse signal that has been corrected for the increase, the fuel is injected from the fuel injection valve 5 in an increased amount at the first increase rate according to the load. The fuel is then supplied to the engine 1, matching the required output during high-load operation and ensuring good output performance.

The amount increase is corrected based on the amount increase rate signal. As a result, the operation of the fuel injection valve 5 is controlled by the injection pulse signal corrected to increase the amount, and an increased amount of fuel is injected from the fuel injection valve 5 to the engine 1 at a second increase rate according to the acceleration. Therefore, it is possible to prevent a fuel delay during acceleration operation, improve acceleration performance, and improve output during acceleration.

ことができる。 On the other hand, when the engine is operating under high load and accelerating, a third increase rate signal obtained by adding the signal obtained by reducing the first increase rate and the second increase rate signal is input to the increase correction circuit 31. By doing so, the fuel injection valve 5 outputs the first increase rate and the second increase rate.
The fuel is injected in an increased amount and supplied to the engine 1 at a third increase rate that is larger than the larger increase rate and smaller than the sum of the first increase rate and the second increase rate, Since it almost matches the original demand, the first
This prevents the air-fuel ratio from overlapping due to overlap between the fuel increase rate and the second fuel increase rate, thereby preventing a decrease in output, and also improves operating performance since it does not cut either the first or second fuel increase rate. can be secured.

As a means of obtaining a third increase rate that is smaller than the increase rate obtained by adding the two increase rates, in addition to reducing and adding one increase rate as in the above embodiment, it is possible to add the first and second increase rates. It may be decreased by .
