Abstract

PURPOSE:In an electronic fuel injection controller to improve the fuel consumption and the operationability, by increasing the fuel in accordance to the increasing ratio to be determined by the control variable incidating the operational state while correcting the increasing ratio in accordance to the control variable indicating the load. CONSTITUTION:Upon the turning off of the throttle valve full-close detection signal LL, the initial fuel injection AEWo is calculated from a memory containing map A to calculate the fuel injection time tau from the basic injection time Tp and the ineffective injection time tauv through the formula tau=Tp(1+AEW)+tauv. Then the constant attenuation DELTAAEW is reduced for each injection by the 30 deg.CA interruption signal. If approximately 100mS is passed after turning-off of the signal LL, the variation rate DELTAQ/N between the rotation N and the suction amount Q is calculated as the parameter indicating the acceleration state by the 4mS timer interruption, to obtain the correction factor from the map B thus to obtain AEW=KXAEW. Consequently the fuel control can correspond to the various acceleration state resulting in the improvement of the emission, fuel consumption or the operationability.
