| description | A method for controlling the fuel injection into an internal combustion engine when it is in a starting condition or in an accelerating condition. When a predetermined control parameter shows a value requiring acceleration of the engine, fuel injections are consecutively effected a predetermined number of times in synchronism with generation of pulses of a control signal having a predetermined constant pulse repetition period and being asynchronous with rotation of the engine, immediately after either generation of a pulse of an engine position signal indicative of a predetermined crank angle of the engine or closing of the ignition switch of the engine has been detected. After completion of the above consecutive fuel injections, fuel injection is suspended until a subsequent pulse of the above engine position signal is generated for the first time after the completion of the consecutive fuel injections. Preferably, the value of the above predetermined number of times of consecutive fuel injections is set in dependence on the temperature of the engine, and the injection quantity of fuel per one time is set in dependence on the value of the above predetermined control parameter, preferably, rate of change of the throttle valve opening. |
