ABSTRACT:
A method for controlling an internal combustion engine equipped with a fuel injection valve fitted to its intake manifold. Repeatedly values are determined of a first quantity approximately representing the proper amount of fuel to be injected, at least partly based upon signals from an air flow meter and a revolution sensor. Simultaneously, repeatedly the current value of a second quantity approximately representing the actual amount of fuel to be injected is determined, at least partly based upon signals from the air flow meter and the revolution sensor, an average value of all the successive instances of the value of the first quantity in some time interval up to the present is determined, and the current value of the first quantity is compared with this average. It is determined whether or not the engine is being decelerated, according to whether this current value is less than this average value; and if the engine is being decelerated and is also fully warmed up, then the current value of the second quantity is increased somewhat, so as to produce an adjusted value corresponding to proper fuel amount. Optionally the adjusted value may be further adjusted. At proper points in the operational cycle of the engine, the fuel injection valve is opened for a period which allows approximately the fuel amount represented by the adjusted value to be injected. A device is also explained, incorporating a digital computer, which practices this method.
