IPC: F02D41/12
Filed: 1984-03-19
Abstract: PURPOSE:To supply an optimum fuel and as well to precisely control the air-fuel ratio of mixture upon transient, by limiting the volumetric efficiency which is used for the calculation of a fuel injection amount within a range that is determined in accordance with the opening degree of a throttle valve at the time when the opening and closing speed of the throttle valve exceeds a predetermined speed. CONSTITUTION:The opening and closing speed of a throttle valve 14 is obtained in accordance with the difference between the preceding and present opening degrees VTA of the throttle valve which are stored in a RAM 36 after being subjected to A/D conversion. Further, the amount of intake-air Q and the rotational speed N of an engine are read out to calculate a volumetric efficiency Q/N. When the opening and closing speed of the throttle valve 14 exceeds a predetermined value, an estimated value QN0 of volumetric efficiency is obtained in accordance with the opening degree of the throttle valve to limit the volumetric efficiency within a range of + or -DELTAQN, thereby the width TAU of fuel injection pulse is calculated. Meanwhile a CPU34 determines the period of the above-mentioned control operation, that is, the control is made during, for example, two revolutions for every 30 deg. of crank angle, or 160msec for every 4msec.
