Fuel is injected into each branch pipe of the MjIK intake manifold synchronously. The relationship between the tl11 rotation angle of the crank and synchronous injection is as shown in Fig. s1 and Fig. 2.

An acceleration signal is output from the signal from the air flow meter.If this acceleration signal is output, for example, just before the 3V damper 0 suction stroke, the synchronous injection pulse 14.1b will be asynchronous as shown in Figure 13. Injection 2 is performed %/- & 9,
As mentioned above, this bottle stand has a Kit 5 $/ring that is inhalable and 1iIK, so the #1 tilt due to asynchronous injection is first inhaled into the cloud 3Fafn, and then sequentially into the s4! Supplied to $1r phosphorus.

１／４求する量の燃料を供給することは困雌でめった。However, since asynchronous injection occurs only once, no matter how much the injection amount is changed, the result is instantaneous KJ or instantaneous KJ.
It was very difficult to supply 1/4 of the required amount of fuel.

入）、次いで雰１．ｊ５．雰４ｖリンメＫＭ次入る。In order to achieve the above-mentioned objective t--, the present invention is characterized in that in addition to synchronous injection, asynchronous injection of the decimal number is performed. For asynchronous injections 2m and 2b, as shown in Fig. 4, for example, when an acceleration signal is generated just before the suction stroke of the s6 cylinder, a synchronous pulse j is generated.
i, 1b and then once between synchronous pulses 1b, 1C, or asynchronous injections 3&, 3b @
When the acceleration signal appears in Figure 5, the synchronization pulse is 1 m, 1
The width and number of asynchronous injection pulses, which may be performed twice during period b, will be determined from the amount of fuel required during acceleration. In the case of Fig. 4, the fuel from the asynchronous injection 2& in the first garden first enters the s3v cylinder (a little goes into the s1 cylinder), then the $4. $2. $I V') gradually increases. Also, the fuel from the second asynchronous injection 2b is primarily sent to the mist 2v ring (a little goes into the $4v ring).
Enter), then Atmosphere 1. j5. Atmosphere 4v Rimme KM enters next.

性能が陶土する。As mentioned above, this invention performs multiple asynchronous injections in addition to synchronous injections at the same time as the acceleration signal, so it is difficult to effectively supply the fuel required by the engine to each cylinder during acceleration. This results in faster engine response and improved acceleration performance.
