Abstract
PURPOSE: To control properly the air-fuel ratio during the time of acceleration by the procedure in which when an abrupt acceleration is detected from the flow rate of air measured, fuel is immediately injected before the start of the next stroke and also when a slow acceleration is detected, a fuel corresponding to the correction of acceleration is additionally injected after the next stroke.
CONSTITUTION: The flow rate of air every a certain time is read in microprocessor and compared with the flow rate of air already memorized at the previous stage to obtain the difference ΔQ. When the ΔQ is greater than the set value KH, it is judged as a abrupt acceleration and an injection time corresponding to the ΔQ is obtained and the flag F is risen to inject fuel immediately. And so, when reading again the flow rate of air after a certain time, the flag F is restored if the injection time obtained previously is elapsed and the air flow rate is memorized. When the ΔQ is smaller than KH, it is compared with the set value KL for slow acceleration and also when it is greater than KL, it is judged as slow acceleration and a correction value for the slow acceleration and the period during which the correctional addition is made are obtained and the injection of fuel is made.
