摘要： An apparatus for use with a multi-cylinder internal combustion engine including a plurality of fuel injectors, each being operable in its open position for injecting fuel into an intake port with which an intake valve is in cooperation for regulating the entry of combustion ingredients into the corresponding cylinder. The apparatus includes a control circuit for operating the fuel injectors in a predetermined sequence. The control circuit determines a length of time one fuel injector to be operated is in its open position in response to selected engine operating conditions. The control circuit opens the one fuel injector at a time to terminate the determined time length substantially at the same time when the corresponding intake valve opens. In addition, the control circuit prolongs the determined time length in response to a demand for engine acceleration produced when the one fuel injector is in its open position.

摘要： A fuel injection control system is directed for a sequential injection type fuel injection internal combustion engine for injecting fuel for each engine cylinder at different timing. Acceleration enrichment asynchroneous fuel injection is initiated in response to an acceleration demand. Acceleration enrichment is further performed for subsequent given injection cycles for compensation of smaller engine load indicative sensor signal than actual engine load due to error in an air flow meter.

摘要： In controlling the air-fuel ratio in an air-fuel mixture in an internal combustion engine, a pulse duty signal Tp corresponding to the basic fuel injection quantity is operated at least from the intake air flow quantity Q and the rotation speed N of the engine, a signal of a fuel injection quantity Ti corrected by adding an appropriate correction value to said Tp is applied to a pulse-controlled fuel injection apparatus. Feedback control is carried out so that the actually detected air-fuel ratio is made to follow the aimed air-fuel ratio, and the learning correction coefficient .alpha.o is operated by learning so that the correction coefficient for this feedback control is as small as possible and the operated value is given as a correction value to Tp. Since the reliability of .alpha.o is low in a driving state area where learning is not advanced, .alpha.o of the area where learning is not advanced is estimated from .alpha.o of areas where learning is advanced, whereby control of the air-fuel ratio in the transition stage between different areas is smoothened.
