Abstract

PURPOSE: In the range of an engine load used except for normal operation status of an engine, to always effect a good operation by performing fuel injection while using the number of revolution and intake negative pressure which have been prepared as parameters.
CONSTITUTION: A pulse width of basic fuel injection set by the number of revolution and intake negative pressure as its parameter over all operation ranges of an engine shall be stored in a ROM20. Furthermore, a basic fuel injection rate set by the number of revolution and opening rate of a throttle valve as its parameter shall be stored in a ROM25. If there is any abnormarity produced in a circuit of a throttle position sensor 21, fuel injection control is automatically changed from control depending on output of the ROM25 to that of the ROM20.
