PURPOSE:To vary a control zone continuously and eliminate the shock of operation by a method wherein the zones are provided based on an operating condition and a smooth shift zone is provided on the way from each zone to the other zone. CONSTITUTION:A map is made in regard to a vacuum and a number of revolution and overall output zones decision threshold curves 1, 2 are described. Basic injection amounts at the upper an the lower limits of hysteresis shown by A-B are read respectively from the map and the vacuum between A and B is interpolated linearly to obtain the basic injection amount. The zone between A and B is the smooth shift zone from a full output zone 3 to a normal output zone 4. Thus, the control zone may be varied continuously, therefore, an operator will never feel the shock of the operation. |
