摘要： A fuel injection control system for an engine includes fuel injection valves, each of which injects fuel to one cylinder a plurality of times during each cycle. The system has an arithmetic device for calculating a required fuel injection amount based on driving conditions and a trailing side injection capability of a trailing side injection time point, a determination device for comparing the required fuel injection amount with the trailing side injection capability and determining which is greater, and a fuel injection controller for setting a leading side injection time point and a trailing side injection time point and setting a leading side injection amount and a trailing side injection amount. The fuel injection controller carries out a fuel injection only at the trailing side injection time point when the required fuel injection amount is not greater than the trailing side injection capability and divides the fuel injection between a fuel injection at the leading side injection time point and a fuel injection at the trailing side injection time point when the required fuel injection amount is greater than the trailing side injection capability.

摘要： An air-to-fuel ratio control system executes a feedback control of air-to-fuel ratio based on an output of an oxygen sensor. The oxygen sensor is judged to be active when a change of the output therefrom occurs to make a fuel mixture rich. For detecting the failure or breakdown of the oxygen sensor when the feedback air-to-fuel control is suspended, the air-to-fuel ratio control system comprises an activity sensor for detecting whether the oxygen sensor is active or inactive, an air-to-fuel ratio altering device for enforcing an alteration of air-to-fuel ratio to make a fuel mixture rich, and a judging device for judging the oxygen sensor to be broken down when no activity detection is made while the alteration of air-to-fuel ratio has been effected.

摘要： A fuel supply control system for an engine associated with a transmission for transmitting the engine output power to driving wheels of a vehicle increases the amount of fuel to be supplied to the engine when the engine is in a particular operating condition in which relatively large engine output power is required. The fuel supply control system receives a signal from a switch which is switched over according to whether the engine is associated with a manual transmission or an automatic transmission, and controls the amount by which the fuel to be supplied to the engine is increased when the engine is in the particular operating condition so that the amount is smaller when the engine is associated with an automatic transmission than when the engine is associated with a manual transmission.
