PURPOSE:To obtain ideal air-fuel ratio by making a signal for controlling air amount follow to timing change of accelerator opening with time lag at the time of acceleration and reduction in a fuel leading type engine control device. CONSTITUTION:In normal operation, fuel amount is obtained from operating condition of an engine and accelerator opening, and air amount is obtained in correspondence with the fuel amount. A throttle valve 3 is opened or closed by a throttle actuator 4 in accordance with the air amount signal. In acceleration and reduction time, air supply amount is varied late from the change of accelerator opening. Thus, ideal air-fuel ratio can be obtained. |
